Science and Technology Log

water from CTD — Here I’m filling up the BOD jar with our salt water samples from the CTD cast.

Reminiscent of my days in high school chemistry, today I had the opportunity to work with our Chief Scientist, Brittany, on completing the daily titration. If you remember, getting readings on the dissolved oxygen in the water is an important part of this survey as we locate any hypoxic (less than 2 mg of oxygen per liter of water) zones or anoxic (no oxygen) zones. This is done with a computerized device on the CTD, but we want to make sure that our readings are accurate. Because “chemistry never lies”, this is how we ensure our readings are accurate.

With our CTD, we have the ability to collect water samples at various depths. We do not collect water samples at every CTD, but rather one or two a day during the daytime hours. We collect water from the bottom to see if there is any expansion of hypoxia.

orion meter — Using the Orion dissolved oxygen meter to measure the amount of dissolved oxygen in our sample.

When the CTD comes back up, we use an Orion dissolved oxygen meter, which is a handheld device, to get a dissolved oxygen reading from our samples. We put the probe on the end of the meter gently into the containers of water on the CTD to get our reading. We will use this number in conjunction with the information sent from the CTD to our dry lab to check against our titration results.

Once we have the reading with the probe, we are ready to take some samples for our titration. We then take the water samples in the cylinders, rinse out our 300 mL BOD (biological oxygen demand) glass bottles a few times with that water, and then fill the botttles up with the sea water from the bottom. These samples are brought back to our Chem Lab (short for chemistry, as I’m sure you figured out) where we will test the amount of dissolved oxygen.

adding manganese sulfate — Adding the manganese sulfate to our sample.

TAS 2012 (357) — This is after I’ve added the manganese sulfate and iodide. Now we have to wait for it to settle.

We are using the Winkler method to find the amount of dissolved oxygen in our water samples. The first step in this process is to put 2mL of manganese sulfate into the bottle. After that, we also add 2 mL of azide- iodide. With those 2 chemicals added, we carefully replace the stopper and give the bottle a good shake. We then can wait about 10-15 minutes for the chemicals to settle at the bottom. Pipettes are used to add the liquids and allow us to be very precise in our measurements.

after settling 1 — Here is our sample after it has settled.

After the particles have settled at the bottom, we add 2 mL of sulfuric acid (which can be a dangerous chemical if used inappropriately), replace the stopper, and shake the bottle again gently. The sulfuric acid “fixes” the solution. Finally we add 2 mL of starch to the solution, which is a blue indicator when we put it in but turns the solution a burnt orange color. Now we are ready to titrate!

adding to beaker — Our sample solution being poured into the beaker, ready for the titration. Inside the beaker is a magnetic stirrer.

finished titration — Now you can see the solution is clear in color, meaning our titration is finished. We are ready to determine the amount of dissolved oxygen.

Prepared beforehand was a burette filled with phenylarsine oxide, what we use to drip into the sample. We pour the sample into a beaker and place it on a magnetic plate. We’ve placed a magnetic stirrer in the beaker so it gently stirs the solution while we are titrating. We let the phenylarsine oxide slowly drip into the sample until it turns clear. When it does this, we note the amount of phenylarsine oxide that we put in the sample (which is equivalent to the amount of oxygen in the water), and the number should match (or be very close) to the reading of dissolved oxygen that we received from the CTD and the Orion dissolved oxygen meter.

This process is quite simple yet yields important results and is just one of the ways scientists verify their data.

Bioluminscence

One other interesting thing happened the other night on one of our shifts. We had brought in a bongo tow and were looking into the codends to see what we got. When Alex began rinsing the sample with some salt water, the whole codend began to illuminate. Why did it illuminate? Bioluminescence. Bioluminescence is essentially a chemical reaction that produces light. Many marine critters can produce bioluminescence, as seen below.

Personal Log

One of the things I’ve probably enjoyed the most about my trip so far are the relationships I’ve formed with the people on board. As a teacher, one of my top priorities is to build and maintain relationships with my students, both past and present. That became a bit more of a challenge to me this past year as I took on a new position and began teaching 600 students rather than the 30 I was used to.

I’ve come to love working with the scientists on the night watch, as each of them brings something to the table. Our watch leader, Alonzo, has a wealth of knowledge that he gladly shares with each of us, pushing us to learn more and find the answer for ourselves. I’ve improved immensely on identifying the different fish, crabs and shrimp we find (thanks to Lindsey, who is my partner in crime for making up silly ways to remember these crazy Latin names for all our species). Where I came in knowing names of very few if any types of Gulf critters, I can now confidently identify 15-20 different species. I’m learning more about how to look for the subtle differences between different species, and Alonzo has been able to sit back and be that “guide on the side” while we work and input all of our data. His patient demeanor has allowed all of us to become more self-sufficient and to become more confident in the knowledge we have gained thus far on this trip.

Alex, another one of the scientists on my watch, shows an endless enthusiasm for marine science. He shares in my excitement when a trawl comes up, and the both of us rush out there to watch the net come up, often guessing how big we think the catch is going to be. Will it fill one basket? Two? Six? It’s even more exciting when we get inside and lay it out on the conveyor belt and can really examine everything carefully. His wish finally came true today as we are now in the eastern part of the Gulf. Alex is studying lionfish (Pterois volitans) for his research, and of course has been hoping to catch some. Today we caught 4, along with a multitude of other unique critters that we have not seen yet. Alex’s enthusiasm and passion for science is something I hope my students can find, whether it be in marine science, biology, or meteorology- whatever it is they love is what I hope they pursue.

Lindsey and Renee are both graduate students. Rene wanted to gain some experience and came on the ship as a volunteer. What a better way to get a hands-on experience! Lindsey has joined us on this cruise because she is doing research on Sargassum communities. She has been able to collect quite a few Sargassum samples to include in her research for her thesis. Lindsey, like Alex, is very passionate and excited about what she does. I’ve never seen someone more excited to pull up a net full of Sargassum (which I’m sure you remember is a type of seaweed) in order to sift through and find critters. She has a great eye, though, because she always manages to find even the tiniest of critters in her samples. Just yesterday she found a baby seahorse that couldn’t have been more than a few millimeters long! Outside I hear her giggle with glee- I know this is because she has found a Sargassum fish, which is her all-time favorite.

Our night watch would not be complete without the deck crew, Tim, Reggie and Chuck, who are responsible for helping us lower the CTD, Neuston and bongo tows, and for the trawl net. Our work could not be done without them.

William, one of our engineers, took me down into the engine room the other day. First impressions- it was hot and noisy! It was neat to see all the different machines. The ship makes its own water using a reverse osmosis system, which takes water from the ocean and converts it into drinking water for us (this water is also used for showers and sinks on board). One interesting note is that the toilets actually use salt water rather than fresh water so that we conserve our fresh water.

I cannot believe how fast this leg has gone and that we only have a few more shifts to go before we return to the Oregon II’s home port of Pascagoula. As we’ve moved into the eastern waters of the Gulf, we have seen a lot of different types of critters. On average, our most recent trawls have been much more brightly colored. We are near some coral reefs too- in our trawls we have pulled up a bit of coral and sponge. The markings on some of the fish are very intriguing, and even fish we’ve seen before seem to be just a little brighter in color out here.

Due to the fact that we are finding very different critters, my list of favorites for today has greatly increased! Here are just a few:

The mouth of a scorpion fish. We’ve caught a bunch of these since we hit the eastern Gulf.

sea horse — A baby seahorse we pulled out of our Neuston tow. He was hiding in the Sargassum.

This is another type of bashful crab, also known as the flame-streaked box crab (Calappa flammea).

The HabCam-ing and dredging continue here in the North Atlantic in calm seas and clear skies!

Alicia Star Oddi — Alicia installing sensor on dredge

I learned a new part of the data collection process with the dredge. Each time the dredge goes out, a sensor that tracks the pitch and roll (side to side and up and down movement) of the dredge on the ocean floor needs to be installed on the dredge. When the trawl is complete, the sensor is removed and the data is uploaded to the computer. It is automatically plotted on a line graph that visually tells the story of the dredge’s movement on the ocean floor. This data is eventually combined with all the other data gathered at each dredge station. Installing and removing the sensor has been my job for the last couple of shifts. To do this, I have to climb up on the sorting table when the dredge is first brought to the surface, remove a metal pin and plastic holder that keeps the sensor in place, remove the old sensor and add a new sensor, then reinstall the holder and pin. This all happens before they dump the dredge. On a funny note, on my way to the sorting table to add the sensor to the dredge earlier today, I managed to trip on a hose that was on deck and turn it on, watering myself and the lab technician that was on the deck with me and entertaining everyone else watching, I’m sure! Luckily, we were all wearing our foul weather gear, so no one was soaked!!

It’s interesting to experience all the different pieces that make a successful dredge tow. Before coming to sea, I guess I just assumed that you lowered a big net to the ocean floor and hoped to catch something. I had no concept of how methodical and detailed each deployment of the dredge really is, from the locations, to the timing, to the number of people involved, to the detailed data collection. The process is still being refined, even on this third leg of the sea scallop survey. One of the scientists on my watch is an engineer who helped design and build the latest version of HabCam. When a part that holds the sensor in the dredge was not working correctly, he was asked to use his engineering skills to create a better way to hold the sensor, so he made the needed modifications right on the ship.

While sorting the haul from dredging stations, I sometimes run across ocean critters that I’ve never seen before. I usually set these to the side to snap a picture after we finish sorting and to ask a scientist, usually Karen or Sean, to identify it for me. It turns out that the strange hairy, oval-shaped creature I keep running across is a type of worm called a sea mouse. In my pictures it looks like a grassy ball of mud, but it’s much more interesting in person, I promise! I consulted a field guide in the dry lab to learn a little more about it. Its scientific name is Aphrodita hastate and it is usually about 6 inches by 3 inches and can be green, gold, or brown. There are 15 gills hidden under the bristly fur. They like muddy areas and often live in the very deep parts of the ocean, so they are only seen when brought up with a dredge or after being tossed ashore in a storm. I haven’t seen any of them in the HabCam images, so I’m wondering if they tend to burrow in the mud, if their camouflage skills are really impressive, or if we just haven’t flown over any. The HabCam moves so quickly (remember, it takes 6 pictures per second) that it’s impossible to see everything in enough time to figure out what it is.

Another item that keeps coming up in the dredge looks like a clump of pasta shells and cheese and it crumbles easily. My initial guess was that it is some type of sponge, but I was wrong. It turns out these are moon snail egg cases. Once I’m back ashore, I think I’ll have to find out more about these.

We’ve seen lots of sea stars, scallops, sand dollars, crabs, clams, hermit crabs, flounder, several species of fish called hake, and skates (relative of the stingray) in the dredge hauls. We’ve also seen most of these on the ocean floor with the HabCam. One of the scientists found a whale vertebrae (part of the backbone) while sorting. It’s at least a foot and a half wide and 8 inches high! Can you imagine the size of the whale when it was alive? Each haul usually has a monkfish or two in it. I’ve heard that these fish are pretty tasty, but they sure look mean! I was warned early on to keep my hands away from their mouths unless I want to get bitten!

Today is supposed to be a day of mainly flying the HabCam, so I’m hoping to be able to interview a few people on the ship about their jobs for use back at school when I’m not flying the HabCam or co-piloting.

Sea stars — Pretty sea stars that came up in the dredge

Personal Log

I ate my first real meal in the galley tonight and it was pretty tasty! The steward, Paul, has worked on this ship for eight years and seems to have cooking a sea down to a science. He has to work and sleep some unusual hours to keep everyone aboard well-fed, but he does it with a smile on his face. Between the meals, snacks, and limited space to exercise, I imagine that keeping fit while at sea for long periods of time can be a challenge. There is a stationary bike next to the washer and dryer, but other than that you have to be creative with getting your exercise. I saw one crew member on the deck this morning with a yoga mat doing crunches and using a storage container to do tricep dips. He said that it’s a challenge, but that you can find ways to keep in shape at sea if it’s a priority for you.

I actually slept better the first few days at sea when I was seasick than I do now that I’m feeling better, thanks to the anti-nausea medication, I expect. I’ve found that earplugs are essential for catching sleep aboard the ship when I’m not medicated! There is one washer and dryer aboard the ship and I’ve had a bit of trouble finding a time when it’s not in use, so I decided to do my laundry at 5 am a day or so ago when I was having trouble sleeping. I figured I may as well use insomnia to my advantage and it was so nice to use a towel that is finally completely dry for the first time in a week!

There are 22 people aboard this ship; 12 scientists and 10 crew members. Four of the scientists and two of the crew are women. Because of watch schedules, most of the time I see only two other women while I’m awake. All that to say, the ship is a pretty male-dominated arena, with lots of ESPN, toilet seats left up, and guy humor. I feel very welcome aboard the ship, but I find that I spend most of my down time doing my own thing, like working on this blog or just enjoying the view, since I’m not much of a movie or sports watcher. With fabulous views of the Atlantic Ocean and beautiful weather, this doesn’t bother me a bit! In fact, I find that I see the most animals swimming in the ocean during these down times. Today it was a huge group of jellyfish swimming next to the ship!

I’m still enjoying my time at sea and am looking forward to learning even more in my last few days.

Dump dredge — Dumping dredge onto sorting table

My last shifts have been a mix of HabCam work and dredging. Remember, dredging is when we drag a heavy-duty net along the ocean floor for fifteen minutes, then bring it up and record what ocean critters we catch. Dredging involves a lot more physical work and is much dirtier than flying the HabCam, so time goes much faster when we are dredging and it’s exciting to see what we will catch. However, it is also kind of sad to see all the animals we bring up in the dredge, because most of them are dead or will soon be dead. You can watch a video about sea scallop dredging here and here.

There are three two-week legs to this sea scallop survey. I am on the last leg. Before the first leg began, a computer program, with the assistance of a few people, decided which spots in the sea scallop habitat we should dredge and fly the HabCam. These points were all plotted on a computerized map and the chief scientist connects the dots and decides the best route for the ship to take to make it to all the designated stations in the available time.

Here’s how our typical dredging process works:

About 10 minutes before we reach a dredge station, the Captain radios the lab from the Bridge (fancy name for the place at the top of the ship where the Captain and his crew work their magic) to let us know we are approaching our station. At this point, I get on a computer in the dry lab to start a program that keeps track of our dredge position, length of tow, etc. I enter data about the weather and check the depth of our dredge station. When the engineer and Captain are ready, they radio the lab and ask for our depth and how much wire they need to send out to lower the dredge to the ocean floor. I get the wire length from a chart hanging in the dry lab that is based on the depth of the ocean at the dredge site and use the radio to tell the engineer, who lets out that amount of wire until the dredge is on the ocean floor. When the dredge hits the ocean floor, I use the computer program to start timing for 15 minutes and notify them when it is time to bring the dredge back up.

Alicia sorting fish — Alicia sorting the haul

The lab technicians and engineer raise and dump the dredge on a giant metal table, then secure it for the scientists to come in and begin sorting the haul. Meanwhile, the scientists get dressed in foul weather gear to prepare for the messy job ahead. That means I’m wearing yellow rubber overalls, black steel-toed rubber boots, blue rubber gloves, and a lovely orange lifejacket for each dredge. Sometimes I add a yellow rubber jacket to the mix, too. Science is not a beauty contest and I’m grateful for the protection! Each scientist grabs two orange baskets, one large white bucket, and one small white bucket and heads to the table. The lab technicians shovel the catch toward each scientist as we sort. Scallops go in one orange basket, fish go in the white bucket, crabs go in the small white bucket (sometimes), and everything else goes into the other orange basket. This is considered “trash” and is thrown back overboard, but the watch chief keeps track of how many baskets of “trash” are thrown overboard during each haul and enters it into a computer database along with other data. After sorting the haul, much of the data collection takes place in lab called a “van”.

Research Van — Research “van” where we gather data from haul

The fish are sorted by species, counted, weighed, sometimes measured, and entered into a special computer system that tracks data from the hauls. Sometimes we also collect and count crabs and sea stars. The baskets of sea scallops are counted and weighed, and then individual scallops are measured on a special magnetic measuring board. You lay the scallop on the measuring board, touch the magnet to the board at the end of the scallop, and the length is automatically entered into the database. Some hauls have lots of sea scallops and some don’t have very many. We had a couple hauls that were almost completely sand dollars and one that was almost completely sea stars. I learned that sea stars can be quite slimy when they are stressed. I had no idea!

Sand dollar dresge — Dredge haul with LOTS of sand dollars

Sometimes my watch chief, Sean, will select a subsample of five sea scallops for us to scrub clean with a wire brush.

Alicia scrub scallops — Alicia scrubbing scallops at about 11pm

Next, we weigh and measure all five sea scallops before cutting them open to determine the gender. We remove the gonad (the reproductive organ) and weigh it, then do the same with the “meat” (the muscle that allows the scallop to open and close its shell and the part people like to eat). All of this information is recorded and each scallop is given a number. We write the number on each shell half and bag and tag the shells. The shells and data will be given to a scientist on shore that has requested them for additional research. The scallop shells can be aged by counting the rings, just like counting the rings on a tree.

Alicia scrub scallops 2 — Scrubbing scallops is dirty work!

Meanwhile, other people are hosing off the deck, table, buckets, and baskets used. The dredge ends by shucking the scallops and saving the meat for meals later. A successful dredge requires cooperation and communication between scientists, lab technicians, the Captain, and the crew. It requires careful attention to detail to make sure the data collected is accurate. It also requires strategic planning before the voyage even begins. It’s an exciting process to be a part of and it is interesting to think about the different types of information that can be collected about the ocean from the HabCam versus the dredge.

Personal Log

Hallway to shower — Hallway to the shower and bathroom

Living on a ship is kind of like living in a college dorm again: shared room with bunkbeds, communal shower and bathroom down the hall, and meals prepared for you. I can’t speak to the food prepared by the steward (cook) Paul, as I haven’t been able to eat much of it yet (I’m finally starting to get a handle on the seasickness, but I’m not ready for tuna steaks and lima beans just yet), but I do appreciate that the galley (mess hall) is open all the time for people to rummage through the cabinets for crackers, cereal, and other snacks. There’s even an entire freezer full of ice cream sandwiches, bars, etc. If my husband had known about the ice cream, he probably would have packed himself in my duffel bag for this adventure at sea!

Taking a shower at sea is really not much different than taking a shower at the gym or in a college dorm… in the middle of a small earthquake. Actually, it’s really not too bad once you get used to the rock of the ship. On the floor where the scientists’ berths (rooms) are, there are also two heads (bathrooms) and two showers. The ship converts ocean water into water that we can use on the ship for showering, washing hands, etc. through a process called reverse osmosis. Sea water is forced through a series of filters so small that not even the salt in the water can fit through. I was afraid that I might be taking cold showers, but there is a water heater on board, too! We are supposed to take “Navy showers”, which means you get wet, press a button on the shower head to stop the water while you scrub, then press the button to turn the water back on to rinse. I’ll admit that I find myself forgetting about this sometimes, but I’m getting much better!

Today there was about an hour and a half of “steam” time while we headed to our next dredge location and had nothing official to do. Some of the people on my watch watched a movie in the galley, but I decided to head to one of the upper decks and enjoy the gorgeous views of ocean in every direction. I was awarded by a pod of about 15 common dolphins jumping out of the water next to the ship!

I’m starting to get a feel for the process of science at sea and am looking forward to the new adventures that tomorrow might bring!

Question of the Day

Hugh R Sharp — R/V Hugh R. Sharp in Port

Well, it took a car, two airplanes, an airport shuttle, a bus, and a short walk, but I made it to the ship in Woods Hole, MA at about 8pm on June 26, 2012! I met a few of the ship’s crew who were kind enough to show me to my room and I slept on the ship while it was in port. You can see a rather long, but informative video tour of the Hugh R. Sharp on this website and you can track the ship’s progress here.

Everyone reported to the ship at 8am on June 27, but we didn’t end up leaving port until about 2pm because of last-minute adjustments to equipment, among other reasons, so the first day was pretty much the hurry up and wait game. While waiting to leave port, we did a safety drill and heard a presentation from a NOAA employee named Deborah about the basics of sea scallops. I was intrigued by all the data that she mentioned in her presentation and talked to her about it afterwards. She is a mathematician with a passion for biology who found a way to merge the two into a career. A big part of her job is to make sense of the data collected on the scallop survey and to present it in a way that can make sense to people. She uses lots of graphs and charts to help the data tell its story. She said that estimation, graphing, and numerous math skills play a huge role in her work. She was kind enough to give me her business card so that we can chat more after I return from sea, as she isn’t sailing on this leg of the survey.

HabCam

Once aboard the Hugh R. Sharp, I learned that this survey will actually be two surveys in one: about half of our time will be spent dredging, sorting, measuring, and weighing scallops. The other half of the time will be spent gathering data with a newly developed underwater camera system called HabCam. The HabCam is about a half-million dollar, 3,000-pound piece of scientific equipment that is controlled by a winch, operated inside the Dry Lab (kind of like a computer lab) of the ship by a joystick and a computer program that shows the depth of the HabCam and its height off the ocean floor. The pilot of the HabCam “flies” it approximately 2 meters above the ocean floor and the copilot keeps an eye on the images coming back from the HabCam. It takes 6 images per second, so there are LOTS of pictures to look at and the clarity is amazing.

Alicia Zip Tie — My first job on the ship

The HabCam is a pretty fascinating piece of equipment that has been under development for several years and is a cooperative effort between the sea scallop industry, NOAA (National Oceanic and Atmospheric Administration), WHOI (Woods Hole Oceanographic Institution), and others. Some of the people that developed the HabCam are on the ship with me and I have had the opportunity to talk to them about its development and uses. Each conversation always seems to have a common theme: the HabCam is a work in progress. We are using version 4 of the HabCam on this scallop survey. As they test the HabCam, they notice issues and make modifications accordingly. It is interesting to see the scientific process in action. Before we left port, they were attempting to correct an issue with pressure and vibration on the winch cable that controls the HabCam while it flies through the water. They thought that covering the portion of the cable directly above the HabCam with zip ties might help break up some of the water pressure and solve the problem. So, my first job as a scientist aboard the Hugh R Sharp involved installing lots and lots of zip ties! I had to laugh when they realized a slight glitch in the plan and had to remove many of the zip ties later. Science is a process!

There are 6 people on my watch and we started with the HabCam. I had the opportunity to pilot and copilot several times. It is fascinating to see images of the seafloor that no one else had ever seen and a bit daunting to be trusted with flying such an expensive piece of equipment through the ocean! We saw skates (like a stingray), sand dollars, sea biscuits, fish, sea stars, and more.

Personal Log

Life at sea is more relaxed than I expected. For some reason, I expected there to be lots of strict rules and procedures, but so far that has not been the case. This has been a welcome surprise for me, especially since despite my extensive anti-nausea arsenal, I am experiencing a rather nasty bout of seasickness. Everyone aboard has been very sympathetic and shared their personal stories of dealing with seasickness as well as remedies for seasickness that work for them (ginger ale, standing outside, etc.). I’m hoping that spending time outside today while we dredge instead of inside flying the HabCam will help. Enough about that!

Bed on Hugh R Sharp — My bed on the Sharp

I share my berth (room) with four other ladies. There are two bunk beds with curtains around each bed to allow for a little privacy and to help darken the room if needed. The berths are in the “belly” of the ship with no windows, so room darkening really isn’t much of an issue! I do think the curtains are sort of ingenious and wish I had them back when I was living in the dorms in college. I am glad that I packed light, since there really isn’t much of a place to store things in the berth. I’m using every inch of available space and wishing that things (like my towel) would actually dry down here, but not much luck with that so far. I managed to be the first person to get drenched on the ship on the day we left and it took three days for my clothes to dry! It’s all part of the adventure, right?

Two of the people I share a room with are on the day shift (noon to midnight) and the other two are on the night shift (midnight to noon), so there really isn’t a time when all four of us are in the room at the same time. When you leave for your watch (shift), you take everything with you that you might need, so you don’t go back to the room while other people are trying to sleep.

There is a constant sucking noise that sounds a bit like wind that I always hear while in my room. I initially thought it was just the sound of the ship going over the water, but now I’m wondering if it might be some type of pump. I checked with my chief scientist Geoff Shook and he told me that the sound is actually the ship’s stabilizer fins. There are 4 fins (2 on each side) that move back and forth to dampen the vessel’s roll and provide a more comfortable, stable ride.

Introductory Log

Greetings from Washington, D.C. and from South Florida! My name is Allan Phipps and I am a teacher from South Plantation High School’s Everglades Restoration and Environmental Science Magnet Program in Plantation, Florida (part of the greater Fort Lauderdale metropolis area). I teach Advanced Placement Environmental Science, a course entitled Solar & Alternative Energy Honors, and serve as a senior research advisor.

Allan Phipps at Capital Building in DC — Einstein Fellow Allan Phipps at the Capital Building in DC

This year, I have had the distinct pleasure to serve as an Albert Einstein Distinguis hed Educator Fellow here in Washington, D.C. at the National Science Foundation. While at the NSF, I have worked with both the Noyce Scholarship Program and the Math Science Partnership, both of which focus on improving the quality and quantity of highly qualified new STEM teachers in high-needs school districts across the country. It has been a wonderful experience working at the NSF and with pre-service teachers. I have also worked with the Presidential Awards for Excellence in Math & Science Teaching program that is operated through the NSF. As a former PAEMST awardee, it was great to be able to work behind the scenes to reward outstanding teachers! A highlight of my experience here in D.C. was when I spoke at the White House Environmental Education Summit! I discovered the NOAA Teacher at Sea opportunity while here in Washington, D.C. working with the Einstein Fellows.

solarknightIII — Solar Knight III racing at the Texas Motor Speedway

At South Plantation High, I am the sponsor of our Solar Knights Racing Team that has won 1^st place in the nation twice in the past six years at the high school level Solar Car Challenge (see video below)! We have been building and racing solar cars at the high school level for six years! Two of the races we have competed in were cross-country, the latest of which went from Fort Worth, Texas to Boulder, Colorado over 7 days in July 2010. Last year’s race was a track race at the Texas Motor Speedway.

I also sponsored our school’s Project ORB (Operation Reef Ball) and deployed thirty 500-1,500 lb concrete reef balls off the coast of

South Florida to encourage coral colonization and propagation to offset some of the damage done to our beautiful South Florida coral reefs. Recently, I had the privilege of presenting a poster session about our Project ORB at the European Geophysical Union conference in Vienna, Austria!

solarkayak — One of my students, Carson Byers, takes the solar kayak out for a test drive.

One of my favorite senior projects was a solar-powered kayak, which would improve accessibility to the Florida Everglades as well as other coastal environments for persons with disabilities. I really enjoyed this project as it blended my passion for alternative energy with my love for getting out on the water. This project won the WOW Award at the Florida Solar Energy Center’s Energy Whiz Olympics!

Now, I am incredibly excited about the opportunity to sail aboard the NOAA Ship Oscar Dyson out of Dutch Harbor, Alaska! This will officially be the furthest north I have ever traveled! As we experience climate change, particularly in areas near the poles where the effects of climate change are more dramatic, it is important to study these changes and how they affect economically important species such as the Alaskan or Walleye Pollock (Theragra chalcogramma). Walleye Pollock is said to be the largest remaining supply of edible fish in the world, and is the fish used in high quality breaded and battered fish products, fish sticks, and surimi (also known as “imitation crabmeat”). Many fast food restaurants commonly use Walleye Pollock in their fish sandwiches. It is important that this fishery be monitored and maintained so that harvest remains sustainable. I hope that I may enlighten my students about their impacts on the environment when they decide what they will eat so they may become more conscientious consumers.

What’s Next?

I am getting ready to head out to sea and am really looking forward to working with the scientists on board the NOAA Ship Oscar Dyson! While my blog will be geared towards my AP Environmental Science students, I hope that people of all ages will follow me along my journey as I learn about the science behind maintaining a sustainable fishery. I also hope to inspire my own students, and others, about the career opportunities in STEM associated with NOAA. Stay tuned!
