The sun set around 7:45, and my first shift began! Sporting a bright orange vest and hard hat, my team helped to deploy the CTD off the starboard side of the BOLD just off Cape Ann in Gloucester, MA.

In this first day (and a half day at that) we were able to sample 7 stations!  Chlorophyll samples are being sent to EPA New England’s laboratory on land in Chelmsford, MA.

Stations labeled “R1…” are located on the Captain’s Log page. New Stations have the latitude and longitude.

At a bit past midnight, my shift ended and we were on course to New Hampshire’s coast. Said, “hello and goodnight” to my roomie who caught the tough shift, she will get back to the room around 4 am.

I wonder what tomorrow will bring!

Hi there! Each day thousands of people are working at EPA to help clean up our environment. I’m one of the lucky few that gets to see how this work is done out on the ocean! My name is Jeanethe Falvey, I’m 24 years old and have worked for EPA for just over two years since I graduated from Bates College in 2007. This week, from July 30 - August 6, I will be onboard the OSV BOLD, EPA’s only ocean research ship. Scientists will be studying the health of New England’s coastline from Boston Harbor to Penobscot Bay in Maine, and I’m here to help show you what life is like onboard the ship.

Each week we write about the science behind environmental protection. Previous Science Wednesdays.

Imagine powering your computer using an energy cell fueled by cow manure. Or using gold dust as the key ingredient in a glamorous yet inexpensive sunscreen?

These products aren’t so far away, and the minds behind these amazing ideas are students between 14-18 years old. Over 1,500 high school students met in Reno, NV last month to showcase their independent research at the world’s premiere pre-collegiate science competition – the Intel International Science and Engineering Fair.

Forget about the blue ribbon and $20 gift certificate for the homemade volcano. These kids were bringing some serious science: biochemistry, electrical and mechanical engineering, environmental management, nuclear and particle physics, cellular and molecular biology, and medicine and health sciences—just to name a few.

Because it looked like such an amazing opportunity for EPA’s Year of Science 2009, activities, I wrote a proposal that would include EPA in the 2009 ISEF as a Special Awards presenter. EPA’s award included an all-expense-paid trip to Washington, D.C. to attend the P3: People, Planet and Prosperity Student Design Competition for Sustainability and display their project on the national mall.

High school sophomore Ryan Alexander was the winner of EPA’s 2009 Sustainability Award with his outstanding project, Gone with the Windmills: An Analysis of the Effectiveness of an Oscillating Wind Energy Generator. Our judges were blown away with this guy (okay, pun intended). Not only was he brilliant (he is skipping the next 2 years of high school to attend college) but he was a poised, charismatic salesman. Ryan was pitching his project with the prowess of a seasoned CEO. We joked about buying stock in his future company.

The best part of my experience at the competition was interacting with the students. After all, they were just kids, but to hear their casual conversations was inspiring. They joked about algorithms and played anagram games. Here, the quintessential nerd did not exist. There were no classifications, just regular people who felt that science and knowledge was the status quo. It reminded me of something I felt at a much less prestigious science fair I participated in many years ago. You can’t let anyone tell you that science is just for people who wear dorky glasses and study quantum physics all the time. Science allows you to appreciate more about the world. By learning and studying it, you can understand anything from how to program a video game to how wormholes might connect possible alternate universes. It even energizes people about manure. How can you say that is not cool?!

Ask any wetlands ecologist what life is like in the field and, if they’re honest, you be regaled with tales of long days and longer nights, weather, mud, being stuck in the mud, boats breaking down, people breaking down and bugs – lots and lots of bugs.

All of my graduate research took place in east coast estuaries where seemingly serene swaying fields of salt grass hide one of the most ferocious and fearsome predators known to ecologists and beachgoers alike: the greenhead fly. I know what you’re thinking, “It’s a fly! Sure they’re annoying but aren’t we being a little dramatic?” If you’re thinking this then you’ve clearly never experienced Tabanus nigrovittatus. With razor sharp mouth parts and giant green eyes capable of tracking a target with military precision, the greenhead is impressive, intimidating and seemingly indestructible. Smack, swat, slam or smash it and the greenhead pauses (probably chuckles evilly to itself) and swoops in for the next round of attack. Oh and I haven’t even begun to discuss the painful bites nor the resulting huge welts.

At this point you’re probably thinking, “Ok, they sound pretty nasty but one or two flies isn’t the end of the world.” Ah, but we’re not talking about one or two flies! Scientists at Rutgers University have collected over 1000 greenhead flies PER HOUR all seeking a “blood meal.” (shudder) If that number doesn’t give you nightmares then imagine my panic when greenheads even attempted to fly down my snorkel in their quest for blood! This is the stuff of horror movies folks yet wetlands scientists persist, nay even thrive, in such an environment. Perhaps the greenhead has met its match?

I’ve done field work all over this country and have encountered numerous creepy crawlies. Heck, I once even had an alligator try to bite a fish trap out of my hand yet greenhead flies stand out. And yet, when reflecting on my many wetland adventures, do I mostly remember the beauty and complexity of the estuary right down to that unique marshy smell (malodorous to some and perfume to others)? Absolutely. Did I tolerate greenheads because my fascination with wetlands overrode my seemingly genetically programmed response to flail my arms around while screaming and swatting? Absolutely. Would I do it all again? Absolutely!

Wetland field stories…if you’ve got ‘em, I’d love to hear ‘em!

In 2007, I participated in the EPA’s P3 Design Competition as a student representative for the Learning Barge project, a design/build initiative within the Schools of Architecture and Engineering at the University of Virginia, to create a unique environmental classroom and field station.

Despite months of planning and building, we seemed to have the odds stacked against us as competitors: after spending a night loading a U-Haul with a portion of the Learning Barge’s prefabricated classroom our truck refused to start the morning we were to drive from Charlottesville, Virginia to Washington, D.C to display our project at the National Sustainable Design Expo.

When we finally, arrived rainclouds threatened to drench our exhibits outside of the tent area. Although we had a nerve-racking start to the competition, our P3 ‘ulcers’ were quickly mended a few days later when it was announced we were winners of a Phase II grant.

The Learning Barge will be located on the Elizabeth River, the most polluted tributary of the Chesapeake Bay, and will provide interactive kindergarten through high school, and adult education about how the river and human activities are inextricably linked.

Unlike environmental education centers located in pristine “nature,” the Learning Barge will traverse an important urban river linking Norfolk, Portsmouth, Chesapeake and Virginia Beach. Moving to a different river restoration site every few months, the Barge will teach participants about the tidal estuary ecosystem, wetland and oyster restoration, and sediment remediation efforts. It is estimated that more than 19,000 students and adults will visit the Barge annually.

The design of the vessel harnesses energy from the sun and wind, filters rainwater and gray water in a contained bed wetland, and utilizes recycled materials and “green” technologies.

Currently, we are just a few short months away from completion, when the non-profit Elizabeth River Project will take over operation of the barge. In anticipation of our launch this summer check us out at: http://www.arch.virginia.edu/learningbarge/.

The recognition we received from EPA’s P3 Competition helped secure several other key grants and awards: an American Institute of Architects Education Award, National Council of Architectural Registration Boards Prize, Waterfront Center Award, United States Green Building Council GoGreen Award, and National Endowment for the Arts Access to Artistic Excellence grant.

March 6, 2009 (Day 26)

For most of our trip so far, the weather has been very good to us, and we’ve been able to keep to our itinerary. But when the weather doesn’t cooperate, all of our plans are thrown off. Unfortunately, that’s the current situation that we’ve found ourselves in as a strong, low pressure front is upon us and the weather is quickly becoming a problem. Rain is now pelting down, and winds are howling out of the northwest with gusts up to 39 knots (about 45 mph).

This will prevent us from working at our remaining stations on the northwest of St. Thomas. It’s not the rain that concerns us, but the sustained high winds that are creating rough sea conditions and will make it virtually impossible to be able to put our small diving boats out into the water. It is what it is, and we all have to keep in mind that this is beyond our control. We go back to the drawing board to figure out what is in our control. We decide to cast off from our dockage in Charlotte Amalie, cruise east, and anchor in Coral Bay in St. John. We’re hoping that the stations in this embayment on southwest St. John, are protected enough to allow diving.

We are so grateful for the assistance of The Virgin Islands Department of Planning and Natural Resource in helping us transport some of our divers, using their fast monitoring boat, the Vigilant. She’s been docked in St. Thomas, so crossing Pillsbury Sound to rendezvous with us could be a difficult task if the seas are rough. But as the BOLD bounds into 4 to 6-foot seas before turning into Coral Bay, we anchor and it seems calmer, and we’re delighted to see the Vigilant anchored at our meeting point. It’s time to get to work.

We’re able to safely load the Vigilant and two BOLD rigid-hulled, inflatable boats on the leeside of the massive BOLD hull. Although stiff winds prevail, the sea surface tucked behind these mountains seems to be staying down enough to allow diving. We’ll find out as divers return and have a chance to report back to us.

As the boats return, the sun is now shining and we learn of success; the waters are workable. Being a glass-half-full kind of guy, I’m confident that we’ll have success in our next two days here on the south side, and we’ll ultimately get the weather to allow us to return to complete our stations on the north sides of St. Thomas and St. John.

Everyone’s heard the riddle about whether a tree falling in the woods when no one’s around actually makes a sound. A similar analogy can be made for the work being one right now on the OSV BOLD; if no one sees what we do, just how valuable is our work?

Yesterday, some 200 people—about half of them students from local middle and high schools—got a close up look at EPA’s coral reef survey and the BOLD’s inner workings through an open house at Charlotte Amalie in St. Thomas. EPA scientists, the ship’s crew and members of the U.S. Virgin Islands Department of Planning and Natural Resources served as tour guides, and demonstrated the coral reef survey techniques and diving operations currently underway.

Apart from seeing all the cool gadgets and gizmos that make the ship run, as well as our dining hall and living quarters, visitors heard about the importance of studying, protecting and enhancing the health
of coral reefs around the Virgin Islands. Bill Fisher, an EPA scientist from Florida who’s been contributing to this blog, told the visitors about how the Virgin Islands, like many small islands around the globe, are specially vulnerable to the potential impacts of global climate change and human activity.

Rising sea levels affect how close people can live to the coast. Elevated ocean temperatures can alter marine habitat and change how some animals, plants and fish function, including coral reefs. The reefs, Bill explained, benefit islands like the Virgin Islands by acting as a natural (and free) barrier to destructive storm surges; man-made barriers cost millions of dollars to construct.

Coral are also particularly sensitive to even the slightest changes in the water around them, so they’re good indicators of looming water quality problems. Bill was clear to explain how almost everything we do on land affects what goes on in and under the sea. He emphasized to our visitors, especially to the students, that lowering one’s carbon footprint can have a demonstrable benefit in their backyard.

Many of the students who came aboard seemed excited to see and hear about what we were up to. Hopefully we inspired them to take action to protect this beautiful and ecologically-significant place. Maybe a few will even become environmental scientists and carry on our work someday.

We’re at anchor in St. James Bay on the eastern corner of St. Thomas, giving us access to both St. Thomas and St. John stations. Our daily routine has already been well established, and with three dive teams making three dives each a day, filling scuba tanks is an essential task. The breathing gas that we use is Nitrox, which is air spiked with extra oxygen. Increasing the amount of oxygen decreases the nitrogen breathed in while diving, which in turn allows for longer dives without saturating our bodies with nitrogen levels that could cause decompression sickness or the “bends.” Nitrox is specially blended daily on board, with factory efficiency, by the BOLD technicians.

Planning for each day always starts the night before, when after dinner, the survey coordinators and BOLD captain meet to finalize dive plans that start the next morning. Dive team assignments are posted in the ship’s laboratory, which serves as a survey operations center. Divers are responsible for checking the oxygen content of the Nitrox in their tanks, and before retiring each night, they must analyze the air in his or her tanks assigned for the next day.

In the morning, divers check the assignment board to see which boat they’re in and the order of boat deployment. The teams stage their gear for loading onto the boats, with care to include all of the dive gear, survey and sampling equipment, drinking water, and oxygen kit. The gear is methodically loaded; missing one piece of equipment or gear would abort a survey and require a return trip to the BOLD. Once the boats are loaded, divers are on their way to start their work. GPS units are used to locate the station, and a snorkeler confirms that the site is appropriate to “count.” If it’s a go, two divers gear up and splash in to begin the survey; in about 10 minutes, two more divers descend to fill out the survey team. The observations are performed and recorded according to our protocol.

When the divers are finished, they return to the BOLD where samples are logged and refrigerated, data sheets are rinsed and dried, and dive gear is rinsed and hung to dry. Data is then entered into computer spreadsheets by the statisticians, with rigid review by the diver. Water samples are filter-processed for various analyses. Logged data for each diver is entered into the dive officer’s spreadsheet to track each diver’s activity and to ensure that no one has built up too much nitrogen in his or her system after several days of diving. After a long day of being the water, the whole process begins again for the next morning.

I’ve spent plenty of time on sailboats and in canoes and kayaks, but just boarding and getting acclimated to the OSV BOLD in St. Thomas was an experience unlike any I’ve ever had on a watercraft.

The ship is like a living organism. Even the smallest pieces of equipment and supplies have their proper place. And no matter where you may be on the ship, if She’s moving, so are you (your stomach included). That means newcomers like myself had better find or re-discover their sea legs pretty quickly or endure seasickness.

In the case of choppy seas most everything is attached to the floor or secured in some other way. All the drawers on my dresser and desk have locks, for example, so they won’t slide out if we hit an unexpected patch of rough water. Safety always comes first regardless of what type of boat you’re on, but on the BOLD, it comes first and second, partly because the ship is so big–224 feet long and 45 feet wide–and partly because of the complexity of what She’s expected to do on a daily basis.

After Her days as a Navy ship, the BOLD was transformed into a state-of-the-art research lab, complete with side scan sonar, biological sampling and analysis tools, and powerful computers to help process all the data that’s collected.

But the BOLD would just be a fancy boat without all the people who make Her work. The 18-person crew knows the ship inside and out, and there’s a chef on board who makes sure we all get three square meals each day.

The team of EPA scientists, who hail from every corner of the country, is nothing short of world class. The coral reefs they’re mapping right now have never been surveyed in such a comprehensive way. People often think that we’ve studied every inch of the planet, but this effort is showing that there are things we still don’t know, especially when the land and water are changing beneath our feet.

Well, we’re cruising back to port at a pretty good clip and the ship’s starting to rock a bit, so I think I’ll go catch up on sleep.
