The last three weeks zoomed by on this little island, and we are wrapping up data collections and switching over to conference mode for our last week in Hawaii.
We were up well before sunrise thanks to jet lag the first week, & enjoyed many beautiful mornings at the beach.
Joey & Blake love spending time with their grandparents
So how is it going? The short answer is fairly well. We (I) spent a huge amount of time prior to arriving carefully selecting a house that was suitable for kids and grandparents, planning travel to arrive a few days early so we could adjust & set up, finding local stores and restaurants, sussing out activities for them, and packing items like power outlet covers and night lights so we could quickly “baby-proof” the beach house. These efforts paid off, as the children made a fairly smooth transition to life in Hawaii. We had a very long day of travel and arrived after their bedtime, so thankfully they were tired enough to sleep until 5am local time the first morning (that’s 10am in Virginia- they usually would wake up at 7:30). Joey was good to go after that. Blake had a few tough nights and we had a little more trouble getting his nap schedule on track, but we are now cruising along with a good routine for everyone. The team agreed that the most crucial piece of planning to everyone’s happiness was the house – easy walk to the beach, bedrooms for everyone plus a lab, and a spacious backyard safe for the kids to play in.
The boys are getting very good at their job – clean dive/snorkel gear with hose
Group hike at Manoa Falls on a family morning
We got into work relatively quickly, sorting out instruments, unpacking gear, and connecting with local colleagues. We had tank experiments up and running within days. Weather kept us off of the water longer than we had hoped, but we managed to start collecting in-water data within a week of arrival and are now on track. Our first week was very busy and the boys started asking for more time with us. Thankfully we crossed off a few big hurdles early on (tank experiments!) and were able to adjust our schedule so that we had a fun family activity with them every few days. We are living in Kailua on the windward side of Oahu, so grand adventures like kayaking, hiking, and swimming are easily within reach for morning play before nap.

Joey & Blake love swimming, especially with Grammy
The boys love spending time with their grandparents, and the beach is a few minutes walk from our front door, so in general their days are spent playing in the sand, swimming in the surf, and enjoying our luxurious backyard complete with banana trees while Simon & I work. When the weather keeps us off the water and/or we are able to schedule half a day off, we take them further afield to different parts of Oahu for hiking, beaches, tide pool exploration, and a couple of memorable boat & kayak excursions.

We have almost completed our data collections, both in water and in tanks with collaborators at the University of Hawaii. We have a few instruments still taking data that we need to pick up early next week before we ship our equipment back to NRL on Thursday, but otherwise we are starting to clean and pack gear. In terms of work, we have shifted to preparing our presentations for the ASLO Meeting this week. My talk is tomorrow morning, so I’m finalizing the details of my powerpoint presentation today while Simon takes the kids on a rock pool adventure (apparently the sea urchins were their favorite animal). We are also taking care to back up data, start running codes for quality control, and organize our notes and photos from the trip.
Joey scrambles over volcanic rocks without trouble
Blake is now a confident walker
A few highlights from our time here include Joey’s growing knowledge of sea animals. After reading a couple of books about sea turtles ingesting trash by mistake, he has led us on quite a few beach clean-ups. Blake is now walking confidently on grass, sand, and rocks. Both boys love to play in the ocean, and scramble around on dark black lava rocks in bare feet with smiles on their faces. We are very happy with our decision to bring them along, and are immensely grateful to the spoilers (Grammy & Papa) for caring for the boys so well and on an ever-changing schedule while we take care of our fieldwork requirements and juggle work needs with family time.

Joey discovered many types of sea urchins & claims they are his new favorite animal.
This expedition has been years in the making, from applying to proposals & gathering funds, sussing out a timeline, and making a plan where we could bring the boys, caregivers, and still get our work done. Here’s what is going to happen & how we got there:
Me & Simon (the science team), Joey & Blake (the nuggets), and Grammy & Papa (the caregivers) are flying to Honolulu on February 1 for one month. We are staying at a rental house by Kailua beach, a short drive from the Kaneohe Marine Corps Base and Coconut Island in Kaneohe Bay, where Simon & I will be working. In addition to space for the six of us, the house has a semi-attached “in-law suite” that will serve as our lab.
It all started with a NASA proposal two years ago that I developed with my postdoc advisor, to inform the HySPIRI satellite mission during an expedition to Hawaii. NASA will fly over the Hawaiian Island chain with hyperspectral remote sensing imagers to simulate HySPIRI data, and during the same time a science team will be collecting data on the ground to validate and test the imagery. We are on the coral reef team. My question is how well coral reef health can be determined from some of the highest quality satellite imagery, utilizing the relative proportion of coral and fleshy macroalgae as the metric of health. This proportion can be detected from space with the correct sensor, and is a well established indicator of coral reef ecosystem state. A healthier reef has more live coral, and a more degraded reef has been overgrown with fleshy macroalgae.
The Freeman & Freeman paper that came out in December was a thorough investigation of passive acoustic indicators of coral reef state in the Hawaiian Islands from our 2012 fieldwork. One of our most interesting finds was that different acoustic signals come from reefs with lots of coral (healthier reefs), versus reefs with lots of fleshy macroalgae (more degraded reefs). We were very interested in testing this further, and seeing if we could use remote sensing & acoustics together to improve the overall ability to determine coral reef state from afar. When Simon started his fellowship as a federal scientist in June, he was given start-up funds and has been able to dedicate part of them to his own, complimentary experiments in Kaneohe Bay in February.
The timeline was heavily constrained by flight time for the NASA aircraft and instruments, but thankfully it was confirmed with enough advance notice that we have been able to get all of our coordinating pieces into place. Simon requested and scheduled his experiment. My parents were able to take a month away from work & home duties, which meant that we could bring the boys. We can’t express enough gratitude to them, as neither of us would be willing to leave our kids for a month right now. The kids, in turn, are so excited for a month on the beach with their grandparents:
We have dreamed for far longer than we have been parents about conducting joint fieldwork and having our children along, a-la Rosemary and Peter Grant style. What an incredible experience for them – an opportunity to live in a new place, enjoy a new culture, and learn about the diversity of the natural world. Not to mention lots of QT with the grandparents. We are beyond excited that this is happening, and can’t wait to share it with you over the blog-channels in the next few weeks.
We made it home! In time for Simon to start his new job! With most of our things!
After our last post, the comedy of errors continued including a rental car with no child seats (did you know that rental agencies are not obliged to guarantee child seats?, and that if you try hard enough, priceline will refund prepaid ‘nonrefundable’ rental car fees?), lost diaper covers, awkward seating assignments on flights, Blake being kicked out of a bar (too intoxicated), etc.
But something strange happened. After the first few days of everything seeming to go wrong, Simon & I stopped being stressed. We accepted the situation, paying an extra $1700 for flights, and moved forward calmly. We worked together to manage the safety, happiness, and well-being of our family first. We met many friends and colleagues along the way who were always surprised when we said our trip was full of things going wrong. “But you seem so calm and happy!” they said. Truthfully… we were.
The biggest reason is that we were with our kids, and my strong feeling is that happy parents make happy babies, and happy babies make everything easier. We both work hard to achieve family happiness at all times, but especially during travel and times of stress. The side effect of ensuring that the boys get time to play outside, timely meals, naps, and bedtime, is that we experience many of the calming benefits and are able to better handle the various fires being thrown at us.
In addition, we had a lot of good things happening alongside the fires. We had productive meetings with colleagues; Simon got good experimental data, we gave various talks, brown bags, and seminars at Scripps and at the International Coral Reef Symposium that were well received; we enjoyed quality family time in beautiful places; and we had happy reunions with friends.
Something else special happened on this trip though. In our times of great duress, we received unexpected assistance from strangers. Random acts of kindness that meant so much given our compromised state:
The strangers that switched seats with us on the red-eye flight from LA to DC so that our family could sit together in one row
The Virgin America flight attendant that provided six little bottles of water when we desperately needed it for the kids
The baggage claim clerk that helped me move all of our luggage to the street to meet Simon with the rental car and I was alone with Blake
The collection of Brazilian scientists at ICRS that happily held & played with Blake during the last night banquet for an hour while Simon & I ate and made friends with them
The friends-of-friends that offered to take photos of our whole family on our last day (and only day on the North Shore!)
The cleaning staff at both hotels we stayed at, who were amazing about providing extra towels and coming back repeatedly so as not to disturb our napping children when cleaning the room
That’s not to mention all of our friends and family that stepped in, whether or not we asked, to play with Joey, hold Blake, and in general help us out immensely. Japanese grammy came all the way from New Zealand to Hawaii to look after the boys during the meeting. She did the typical grammy thing – spoil Joey rotten with care and attention – so that now Joey wants to “go back to Hawaii”. Why? “Obaasan”.
Those relatively small kindnesses made all of the difference for these strung-out parents that wanted to bring their kids on a work trip. Kindness matters most to those who need it. Look for the need and pay it forward. You might be in the needful position some day.
I wanted to call this “When the Shit Hits the Fan,” but I’m pretty sure my mom reads it.
You may have gathered that we have taken to the air again with our two kiddos and are currently in Hawaii. The lack of a pre-departure post is a fair indicator of our lack of organization for this trip.
Usually, I am a super-planner. Every detail thought out, from snacks for everyone on the plane to printing out hotel confirmations and addresses ahead of time (or more recently, saving them to my iPhone). Simon is surprised if I cannot spout off our itinerary in detail at any point on an adventure.
This trip was not well planned. In fact, it coalesced together in a messy fashion after we both were given slots for conference talks at the International Coral Reef Symposium in Honolulu this week. From there, we slowly added on items. We decided to bring both boys & a dedicated care giver (Japanese Grandma!). We decided to come to Honolulu early to use rewards nights at the Marriott for our anniversary, and to stay the weekend after the conference with friends on the North Shore of Oahu. Somewhere along the way, we had the idea to make a long layover in San Diego en route to Hawaii where we would visit Scripps to give talks, catch up with friends & colleagues, and Simon would collect some data off the pier while we were at it. So in summary, in two weeks we would visit two cities, stay in six different places, do a wide variety of work things, vacation with our kids, and catch up with friends.
What could go wrong?
Turns out, a lot:
We forgot toothpaste
We didn’t realize that we wouldn’t have childcare in San Diego for all of those talks and experiments & had to modify our plans at the last minute
Joey took three days of sharing a room with Blake to nap quietly without waking his brother, much to my dismay
Our bags didn’t really fit in the rental car with the car seats (so I had either a large suitcase or stroller on my lap)
Renting car seats with the rental car is expensive & they didn’t tell us that ahead of time. In fact, our first rental car reservation added so many costs & fees that Simon elected to cancel it and find another rental car at the airport, adding nearly an hour delay before we got to our digs for the night.
We missed our flight from San Diego to Hawaii and had to fly standby the next day
On our standby flight, we were seated behind another child who spent a lot of time screaming, making it extraordinarily difficult for our non-screaming children to nap and remain well-behaved
We lost Simon’s wedding ring and the quadcopter (not at the same time)
We continue to not have baby wipes available when we need them, despite bringing at least five packages with us
I’m forever optimistic, and am inclined to now list the things that are going well. I’ll spare you bullet points, but will say that we are still having a good time and for the most part the boys are not phased by our stress and struggles.
Our little champion flyers wait patiently to get on the plane to Honolulu. Our standby tickets meant we were last to board.
After three days in a hotel, I finally had two children napping at the same time!
We were as happy as we look here all day in Waikiki, despite various struggles before and after.
Blake scored us an upgrade to the oceanfront suite at the Waikiki Marriott – an unexpected perk along the way!
Whether this trip is a set of unique challenges or a complete disaster depends on your point of view. For example, we found ourselves leading a discussion with graduate students about government jobs and postdocs while holding a very alert and cheerful Blake, watching Joey play with the foozball table out of the corner of our eyes. At least we’d had the foresight to suggest this event occur in the graduate student lounge? And the grad student coordinator that organized for us had kindly provided Joey’s favorite snacks (bagels) as refreshments, further sweetening the deal for him. In fact, he has been asking to go to another “work meeting” with us since.
So what do you do when your plans fall apart? Or you failed to make a plan in the first place?
Make a new plan stat.
Simon & I will waffle endlessly about things like where to go to dinner – until we get to a critical situation. Then we both switch gears and start damage control. We dish out orders to each other and the children, and follow one another’s instructions exactly.
This trip has been a healthy reminder that planning is important, but even more important is learning to roll with the punches and make the best of it. We could have let various challenges ruin this trip, but that would have been a much bigger loss overall. The kids mean that we spend more money (missed flight? better just get a new hotel and go out for lunch so the boys can eat & nap), they also keep us on the happy end of the spectrum. They achieve this magic partly because we want the best for them, including happy parents, and partly because they are delightful and they cheer us up. Joey has even started making jokes. We also have some perspective that the most challenging situations wind up being some of our favorite memories and most endearing stories later on.
That ^^ was supposed to be the end, in hopes that posting would put an end to our comedy of errors. Nope! Cue some important emails to Simon yesterday about his first day as a federal employee – not only does he have to be in the office in person with paperwork on Monday, but he needs to arrive no earlier than 7:30am and no later than 8:00am. Our flights would not get him there in time.
We each had our own itinerary on the same flight, and Joey was attached to Simon’s. Much of our first day at the conference was spent looking for flights, calling airlines and travel agents, and establishing that Simon really had to be at work by 8am Monday (he does). We went through a string of options and came down to the choice of 1: buying Simon a new flight home early, while I traveled alone with both boys on a red eye and really hoped that they would let me add Joey to my reservation without asking for large sums of money or 2: cancel all of our flights home and buy three seats on an earlier flight together.
I think we’ve finally learned something from the last few weeks, because we picked #2. This sadly means cutting our family fun weekend on the North Shore a little short, but based on how things were going we decided to plan conservatively.
What else can go amiss in the next few days? Stay tuned for updates 🙂
There have been many times when people commend us on our environmental ethic. I am proud to say that some things Simon & I do are intentionally to try to help the environment- reusable shopping bags, walk/bike instead of drive, buying local foods, etc. However, there are many, many more things that we actually did to save money, and later realized that they had a big side benefit of helping the Earth too. Here are some examples – you might find a helpful hint for your own life in here!
This is a general post that leads to many others – reusing things instead of throwing them away. Do you have other ideas of
Are you sensing a theme here? The original three R’s of being eco-friendly from my childhood were reduce, recycle, and reuse.
Reusing things is one of the very best ways to save money, and it has a nice positive environmental impact as well. The principle is very simple – instead of buying a disposable object (i.e. paper napkin), using it once, and throwing it away, you have a slightly sturdier version (i.e. cloth napkin) that you use over and over, washing between uses.
This almost always results in financial gains long-term. The initial investment is often (not always) higher for a reusable item than its disposable counterpart, but it only takes a month or two to break even and start saving money. To really do things on the cheap, many of these items can be crafted from other things that you already have around the house, saving you even more cash. Another perk is that the reusable versions of products are almost always more aesthetically appealing, and will hold up better to the kind of abuse we put our things through. Each individual thing may only save you a few dollars a week, but bundle a few of them together for a couple of months and it really adds up! Here’s a list of items that we reuse with a few pro tips for each.
I bought a bottle of water in a gas station the other day for $2.50. You’ve got to be kidding me! You can get a wide range of reusable water bottles (or make your own from a previous water, soda, or juice bottle) that can be refilled for free to a few cents in virtually any restaurant, service station, or home in the western world. If you have concerns about BPA and other plasticizers, stainless steel or aluminum bottles are easy to come by for as little as $4.99 in general stores.
I know, I just told you to make your own coffee at home, so you aren’t getting all of those paper and plastic Starbucks cups anyway, right? It never hurt anyone to have a to-go style coffee mug ready for that homemade coffee or the off-chance that you need a second caffeinated beverage from your neighborhood café around lunchtime. Most places (including sbux) give you a discount for bringing your own cup, and the insulated versions keep your drink warm or cold much longer! These are also easy to find in stainless steel for under $10 (although not at sbux 🙂 ).
Cloth napkins range in price but can be found for less than a dollar per napkin. We have a set of 12 that I bought for $5.99 on sale six years ago that are still going strong. They are softer and more absorbent than paper napkins (an important feature with our little mess-maker), and take up very little space in the laundry so really do not affect our energy and water budget for washing! This was also one of the great Tim Ray’s top ten environmental tips.
Use these for drying dishes, covering baked goods before serving, drying hands, and wiping down the kitchen table. This again minimizes your need for paper towels. Dish towels and napkins have a huge price range, but simple cotton sets can be found at target or dollar general for a few dollars.
We use a wide range of glass containers with lids for leftovers and airtight jars for dry goods in our pantry. Ikea sells the storage jars for a great price, and almost any grocery store or target sells the pyrex and Tupperware storage containers. There are also a plethora of cute snack bags, sandwich wraps, and specialty reusable lunchtime paraphernalia available on the internet. It takes a little longer to realize savings here, but over time all of the zip-loc bags, plastic wrap, and aluminum foil add up. The environmental impact is big – far fewer one-time wrappers being manufactured and going to landfills. For more cost-savings, save jars from pasta sauce, salsa, yogurt, etc to use for your leftovers or packed lunch.
Once towels get old and torn, they move to our cleaning bin. We use them to mop stains off the floor, clean windows, and clean off surfaces in the kitchen. All jobs that were once held by paper towels (which we do have but almost never use now!) It is possible to buy this new, but we’ve never had a shortage just by using old towels, sweatshirts, etc so this item is virtually free and starts saving your change from paper towels immediately.
We have an extensive collection of reusable grocery bags by now, collected from various events along the way. I have a fleet of heavy-duty totes (mainly these from LL Bean), which are awesome for shopping (as well as travel!), especially since Joey and I walk to the stores most of the time. I know you’ve heard of this before and you know it is eco-friendly, but how on earth does it save you money if you go out and buy new bags when the store gives them to you for free? Well, most stores give a per bag discount (usually 5-10 cents per bag) if you bring your own. They will honor this even if you save and bring back the plastic bags from your previous visit. However, plastic bags have been outlawed in Hawaii (all of Maui and Kauai), San Francisco, and Portland completely, and many stores and states are implementing policies where customers are charged per bag for plastic or paper bags. So again, not a huge savings but it adds up over time. The reusable bags are far sturdier and have never failed on me, while I’ve had at least four memorable events where a grocery bag has catastrophically ruptured and spilled/smashed food at an inopportune place. If you do get paper or plastic grocery bags, hang on to them to bag your recycling, use as trash bags, carry wet clothes home from the beach, and more.
Flannel and cotton baby wipes are available to purchase online, or you can make your own from old flannel sheets and t-shirts. (We also made burp clothes! I used a mix of upcycled t-shirts, an old sheet, and some new flannel from the fabric store.) Like cloth napkins, these take up very little room in the wash and don’t affect your water or energy budget. Many moms make their own wipes solution with various soaps and oils, but we just use plain water and it has always worked well for us. Keep wet wipes on hand with a dispenser like this at home, or in a wet bag at home and on the go. This saves $100-$400 a year depending on the type of baby wipes you would typically buy.
I had to make this in to a whole separate post because I’ve gotten so many questions about it that I wanted to answer. At the end of the day, cloth diapers have an initial cost of $200-600 depending on the type, brand, and quantity. They can be re-used for subsequent children (although you may need more for twins or multiple babes in diapers). Washing costs (if you have your own machine) are about $30-50 a year. Paper diapers cost $800-$1200 per year depending on the brand, so you save about $550 in the first year and $1000 each subsequent year your baby is in diapers. The environmental impacts of this one are huge – tons of material not going into landfills and heavy manufacturing burdens and greenhouse gas emissions that you aren’t supporting.
Upcycle Your Old Things!
We have developed a knack for assessing an object for its potential usefulness before it is sent to the rubbish bin. Old t-shirts, sheets, and towels can be transformed into baby wipes, cleaning cloths, and more. Pasta sauce jars can be washed and used for food storage. Cardboard boxes become forts for Joey. The little bottles of shampoo from hotels can be saved for guests, and re-filled from your big shampoo container for future travels. That tent that isn’t really waterproof anymore still makes a great sun shelter in the yard for kiddos. Anytime you can come up with a new use for something, with or without modification, you are minimizing the demand for newly manufactured items and the load sent to landfills. Get creative – and please share your favorites! I’m always looking for new ideas for our family and home.
How Does This Help The Planet?
Nearly everything you buy in a store has to be manufactured in a factory, shipped to a distribution center, then shipped to that specific store. The carbon emissions and pollution add up quickly, especially since so many things are manufactured overseas. The less you buy, the less demand you are giving the manufacturing machine, so it will eventually respond by reducing the supply that it produces. When we throw things away they don’t just disappear- they are sent to landfills (again, carbon emissions and pollution), which we are rapidly running out of space for. (Think Wall-E)
We’ve almost never deployed or collected our instruments without additional flotation of some kind. A raft helps us transport heavy and large equipment from shore, and when equipped with a dive flag, signal to others where we are. We’ve had to swim out quite far in many places – the beach at Nu’u bay is far from deep water, hydrophones needed to be distant from the boat traffic at Maliko gulch, and we needed to show where we were to the boats coming in and out of Kewalo basin.
Our first ‘vessel’ was the “Sea Hawk 300” – a toy inflatable boat complete with plastic oars we got for $30 (what a bargain!). Apart from its tendency to occasionally leak it was a great help, hauling equipment from the beach to dive sites and back. It even served as a real boat when Simon had a cold and followed Lauren as she snorkeled to retrieve the instruments at Electric Beach, Oahu.
We had a few problems with the sea hawk. We left the car keys inside while we were down which didn’t go well on one occasion when the waterproof plastic bag with the keys inside took flight over the side. If anyone ever finds a floating bag on a pacific beach with a new-looking Volkswagen keyfob inside (which should be in perfect working condition), its worth $370 when returned to Enterprise.
The line connecting the sea hawk to us was fairly thin and had the disconcerting tendency to break. This happened three times at Kahekili bay on Maui’s west coast. Luckily, each time the stiff tradewinds were blowing along shore. As soon as it was discovered that the boat was gone the drill was the same – everyone surfaced and swam to the beach, whoever got there first would dump their gear and run downwind. After running a kilometre in a full wetsuit and then walking back upwind with the sea hawk in tow several times, we upgraded the line to an anchor warp. It was hoped that the extra hassle of carrying a heavy line like that underwater would be offset by never having to retrieve the boat again. We were right about never having to retrieve the boat again, but wrong about the rope..
Our deployment at La Perouse Bay, southern Maui, involved a swim of a couple of hundred metres offshore into water between 10-20 m deep. The tradewinds were fairly strong this far from shore and we could feel them constantly tugging on the sea hawk while we were underwater with the heavy line clipped to our belts. During the last survey of the day we clipped the sea hawk to one of the anchors that was already screwed into the sand. When we came back…it was gone! The line hadn’t snapped. Instead, the spring loaded swivel snap had somehow come undone – something very difficult to replicate (as we tried many times) but possible under the right conditions. We surfaced as fast as we could (which was fairly slowly, as we had equipment and an ascent rate to watch) and looked for the boat. If it was close enough we could make a dash for it, or so I thought. I will never forget the view on the surface: a wild and windswept sea, a glowing sunset over Molokini, and the sea hawk flipping over and over wave crests far in the distance, forever freed from its anchor and on its way to the deep ocean via the Lanai channel. If it made it past Lanai, Molokini, and Maui, its three independent floatation chambers may mean that sea hawk will voyage over the north pacific gyre for many years.
Both of us were rather upset. It was sunset and we had to swim back to shore with all our stuff. We had become used to the convenience that sea hawk provided. What shall we do? We swam back to the beach and discussed/commiserated on the way home. Could we find an inexpensive replacement on Maui? Craigslist was consulted and sea hawk #2 (A.K.A. ‘the donut’) was found.
The donut is actually a ski tube (or ski biscuit in NZ). Bought for the humble sum of $25, it proved its worth the first time we used it – in choppy seas on Maui’s north shore where the sharp rocks might have pierced the thinner hull of the sea hawk.
Sometimes however, the distance between shore and where we want to put our equipment is just too far to swim. We have a permit to do our work in the marine reserve at Kealakekua bay on the Big Island, about 2 km from the nearest shore access. Although almost no-one swims, hundreds of kayakers make the trip every day to view the monument in the place where Captain Cook was killed and to snorkel the reef. We were tempted to use a kayak. But to rent or buy? The going rate for a double kayak is around $60 a day. We would need one here and at two other locations, so we would end up spending at least $300, which was roughly how much used double kayaks were going for on Craigslist. To cut a long story short we bought one – the “Pelican apex 13 twin”. Whether or not we save money depends on whether or not we can sell it in a couple of weeks!
Regardless, it works very well after a few quick mods (there were no porthole lids, so some real estate signs were sacrificed). The one exception was when we tried to take our scuba gear on board with us. With the tanks in the footwells, the centre of gravity is dangerously high. If you neatly put your mask away in the foot pocket of your fin (which sinks), its impossible to find everything on the bottom when the kayak tips over and spills all your gear! Luckily this occurred in a shallow safe place during our ‘sea
trial’ deployment at Puuhonua o Honaunau (Place of Refuge) Bay and a short swim to the car (to get a spare mask) meant that we recovered everything. We now tow the donut (with our dive gear inside) behind the kayak as a kind of trailer, which works very well. Needless to say we get quite a few comments from the other kayakers.
Initially we thought we would be spoiled rotten during our time on the cruise. The idea of working from a small boat with a tender seemed so much easier than lugging all of our heavy equipment between car and beach, and beach and dive site. Such luxury would be hard to come down from, and we weren’t sure how we would handle it.
Turns out that some of those original assumptions were wrong. Fortunately, it wasn’t too big of a shock- since our original assumptions often turn out to be wrong!
Working from the Hi’ialakai was awesome, and we got to visit some of the most amazing underwater places on earth. However, it was also extremely difficult. We had to move heavy equipment between decks, and on and off our small boat every day. The small boat was often out in rough seas, which made dealing with our gear challenging. We were both looking forward to begin shore diving operations this past week to see how it compares.
The Perks of Shore Diving:
1- All gear (diving, photographic, and acoustic) can be assembled on land. It may be sandy, but it will definitely not be rocking, and no one will be seasick over the side while putting hydrophones together.
2- No one uses our car except for us! Unlike the small boat, which had to be emptied every day, our car can be the semi-permanent home for clean gear, removing one of the lugging stuff around steps.
3- Towing a raft full of stuff isn’t much harder than towing an empty raft. We had to tow a surface float at all times on the cruise, so our trusty SeaHawk raft doesn’t seem very different in terms of effort. It does serve a much more functional role as the main gear transportation device, however.
4- Surface swimming is great exercise, and you get all the pros without much risk of serious injury. At least, not much risk compared to lifting 50-100lb piece of equipment or bracing oneself against 2-3 meter seas in a small boat.
5- I get to pack our cooler! With whatever I want! Instead of sifting through the same array of potato chips and crackers that weren’t particularly appetizing on the first day (much less the 21st), we fill our cooler each morning with foods we like for lunch and snacks. What a great idea.
6- If someone becomes sick and can’t dive, the other one can just pick the gear up snorkeling- no lost equipment! This happened today when Simon’s cold was still too persistent for diving, and I recovered the two small hydrophones and camera tree from a dive site. He helped from the SeaHawk, which incidentally also works well as a small rowboat.
7- Shave ice. Instead of celebrating another successful deployment with increasingly stale cookies, we can each select our own preferred flavors of Hawaii’s best frozen treat.
All of our experiences in Hawaii have been incredible, and our time on the Hi’ialakai was nothing less. We both learned so much and got to see the most amazing things. But the challenges of really working at sea were real. We learned how to take it all in stride and had an awesome time, but being relieved of those challenges makes us appreciate what we doing now that much more!
I can’t believe this day is here already- we are embarking on a five day transit back to Honolulu! Our amazing adventure to the Northwest Hawaiian Islands is drawing to a close.
We visited a total of four remote islands- French Frigate Shoals, Pearl & Hermes, Kure, and Lisianski. Each had its own unique character, both above and below water. Kure was by far our favorite, as you may have gathered from our earlier enamored blog posts! A combination of beautiful weather, extra time, and perfect diving really sold us on Kure atoll. At each island, we put out three different types of hydrophones to record acoustic data for two days, and 3-6 time lapse cameras. We also completed surveys of the surrounding ecosystem, using photo mosaics, transect lines, and fish counts amongst other things to quantify the character of each individual site.
We have learned firsthand about some of the most pristine ecosystems in the world, and collected as much data as we possibly could with the amount of small boat time we were given. We are both looking forward (really!) to analyzing it and turning it into scientific papers and PhD chapters. It is far more meaningful to research something that you got to experience yourself.
We have also learned some of the ins and outs and eccentricities of living on a research vessel and working at sea. It has been quite an experience in of itself! Lauren’s feeling is that this was an incredible opportunity, but she doesn’t want to base her career on working in such remote areas. There is so much planning, logistics, and time involved in collecting data, and at any moment technical difficulties or weather could preclude you from getting what you need!
On our last dive at Lisianski, we had two casualties. One was relatively minor- Lauren was bitten by one of the large ulua that have followed us around every dive site up here. It was a small injury, but certainly a big reminder that we are diving with large predators, and that they are not afraid of people! Much more significant was an incident that we began to suspect when the hydrophone array was not as buoyant as usual when we brought it up from Lisianski. Upon getting back to Hi’ialakai and opening the battery and computer cylinders, Simon quickly learned that the computer compartment had flooded with seawater. He is working hard to salvage as much of the equipment as possible, and will send the hard drive off for data recovery once we return to land.
Equipment failure is a normal part of field work, but this was our first big hit. We are now both working on developing modified field plans and experiments for our upcoming time on Oahu, Kauai, Maui, and the Big Island. We appreciate all of the mentors who have reassured us that this is to be expected in seagoing work, and rather an important experience that comes with being a graduate student!
We are steaming back to Honolulu against swell and wind, so the Hi’ialakai is only doing 8 kts (she did 10.2 kts on the way out). It will still take four full days from Lisianski. We are scheduled to make port at 0900 Friday, August 24 (Honolulu time). Feel free to give us a call on our cell phones after that! We are looking forward to catching up with all of our family and friends on the phone, skype, and facetime. We’re planning a ‘vacation’ three day weekend when we return to rest and recover, and then we’ll be getting started on our next Oahu leg after unloading our stuff from the vessel. We’ll also be back to public blogging when we are off of the NOAA ship.
This cruise has given both of us some of the most amazing experiences of our life. The diving has been spectacular, in particular since we were in the water alone- never on a tour or as part of a large group, and often in places that may never have been dived before (or again!) We were so impressed by the natural curiosity and un-altered behavior of all of the animals that we encountered. By far the most memorable were the impromptu ‘lunch’ snorkels with dolphins, manta rays, monk seals, and sharks. We were completely alone in the sea with these beautiful swimmers, who were in their natural habitat and acting as they ‘should.’ (Before humans pushed these species out to the fringes, anyway). Our sense of ocean wonder has only grown from this trip.
We got lucky yesterday- we were given a full day at the last minute instead of a half! We used the extra time to explore Kure Atoll, and for the first time we brought our ‘big’ camera along for the ride. Here’s a collection of some of our favorite shots from the day. We are currently steaming full speed to our last stop, Lisianski, and gearing up for our final gear deployment on this cruise! (PS- don’t let our last title confuse you. It’s pronounced cure-ay)
Sunday saw us retrieving the last of our acoustic equipment from the lagoon at Pearl and Hermes atoll, which went very well. All through the dive Lauren and I had been admiring the half-dozen or so galapagos sharks that had shown up. We sent the hydrophone to the surface and watched them swimming around for about 15 minutes. As we ascended the sharks became more curious, reducing the distance between them and us. Being in blue water and surrounded by sharks and big alua was very special – so special that our coxswain and one of the science outreach team got back in the water for some snorkeling. Soon, the coxswain suggested they be picked up as the sharks were becoming very curious. After they got in the boat, we dropped over the side for a look. Initially, there were around four sharks visible in the very clear water. The bottom could be seen clearly, easily 30 m below. Slowly, the number of sharks began to increase. In almost no time at all there were around twenty galapagos sharks below our feet, swimming close by and inspecting our flippers. Lauren reports that this was one of the most amazing experiences of her life. Looking down on the school of sharks was absolutely incredible, and the visibility was perfect so we could see them all the way to the sandy bottom.
We motored overnight to Kure and were back in the water first thing Monday morning. We’re back from our first day’s diving at Kure Atoll, the northernmost atoll on the planet.
Initially formed much further south in warmer waters, Kure has been slowly transported north by the tectonic motions of the pacific plate. Sometime in the future, conditions will presumably be too cold for corals to grow. Right now, it’s hanging on, barely at the edge of the tropical currents that sweep through the Hawaiian Islands. Consequently, the species we see here are like what you’d see in Northern New Zealand!
Our first day of diving at Kure was very nice (Lauren says it was idyllic). Both topside and underwater colors were vibrant and bright, and most of the views we saw looked like they could be used for postcards. The term “gin clear water” describes well what we saw off the southern side of Kure atoll. Underwater visibility is around 50 m, making the search for an ideal hydrophone deployment site a task we could do from the boat, rather than having to get in, dive down, and swim around.
We motored over an expanse of spur-and-groove coral habitat, and an ideal section of white sand straddled by two high spurs of coral reef was selected as a candidate site for our equipment. Diving down, a few galapagos sharks immediately came in to view. They stuck around but their numbers did not swell to what we had seen the previous day at Pearl and Hermes. The white sand was deep enough for our sand anchors – a critical aspect we needed to check out before the flyby array was bought down to the sea floor. The coral spurs adjacent to the sand were teeming with a large number of different fish species – there were hundreds of fish, but it seemed that there were very few which were alike.
The tropical species which are so familiar to us were there (surgeonfish, squirrelfish, angelfish, parrotfish, wrasse), but they were also joined by subtropical varieties (morwong, boarfish, endemic butterflyfish, etc). Interestingly, big snapper hung out near one of the overhangs, a good sign that fishing had not really taken place here in some time. The coral situation was an interesting one – the large spurs of rock on which coral was growing are clearly made from calcium carbonate, or dead coral. This suggests to us that at one stage massive reef-building corals existed here. Nowadays, however, small porites colonies dot the surface of the rock, too small and sparse to build reef, but enough to maintain habitat for the animals which rely on live coral growth. This was the first site on this cruise where Lauren spotted one of her favorite sea slug relatives, a neon yellow and black flatworm.
The flyby and another hydrophone were put in the water and bought down to the bottom in short order. Working on the sea floor here was a pleasure not just because of the stunning scenery, but because it was also so calm! Our time at Kure is the first time on this cruise we’ve experienced good weather. The surface was mirror calm, the swell was of low amplitude, long-period, and manageable. We took a number of photographs of the array deployment, which runs as follows:
1) Assemble the hydrophone cable, battery pack, and data acquisition computer together. 2) Power on (don’t forget!). 3) Simon and Lauren kit up and enter the water. 4) The coxswain places the cable in the water, and lifts the computer/batteries to the boat gunnel. 5) The array is lifted from the gunnel and lowered into the water, Simon guiding it in while the coxswain does the lifting. 6) A rope is tied to the array and the divers descend to one of the sand anchors. 7) The rope is strung through an anchor eye and the array (very buoyant) is slowly pulled to the bottom. 8) As the array reaches the bottom, Simon maintains tension on the line while Lauren ties the array off to the sand anchor using a shorter rope. As soon as this is done, Simon can let go and relax! 9) The array cable is strung out and fixed to other sand anchors, the array geometry being carefully measured so we’ll be able to process the data with greater accuracy later on. Retrieval is the reverse of deployment – the only difference being that it’s much harder to bring the array back on board the boat than it is to put it in the water. Hopefully Wednesday will be just as calm!
Once the array, another hydrophone, and our camera ‘tree’ were in the water, we moved site to deploy one more hydrophone and a couple of cameras in the inside of Kure lagoon. Arriving on site inside, it was immediately clear that things were very different here. The slow ocean swell was gone, replaced by some confused wind chop (wind and swell were in opposing directions). The clear blue water outside was gone too, and in its place was something more greenish. The
environment on the shallow lagoon floor was like what you would experience in a harbour. Fine silt, lots of dead coral, many small fish, including juvenile versions of what you’d find outside the lagoon. Visibility was worse but not bad. The temperature was considerably warmer at 28 degrees (as opposed to 25-26 outside). We positioned our equipment and began surveys. What initially looked to be piles of dead coral rubble turned out to harbour lots and lots of small critters – many kinds of reef fishes (including a boxfish!), cone shells (venomous), juvenile fish, rock lobsters, polychaetes, sea cucumbers, and some pufferfish! While definitely a dive where the small things were of greatest interest, the lagoon was an equally fantastic place.
Its our day off today due to the boat shortage. We’re taking advantage of the down time to sleep in 🙂 enter data, back up data and photos, update our notes, and of course write a new blog! We’re planning to head back out tomorrow morning for a half day to retrieve our gear before the Hi’ialakai steams back east towards Lisianski tomorrow night.
