Hello and welcome! I am so excited to be a part of the NOAA Teacher at Sea experience. I currently teach chemistry, engineering, and technology at Lanier High School in Sugar Hill, GA (outside of Atlanta). I am part of an awesome project based learning (PBL) program called CDAT (Center for Design and Technology), which focuses on science, technology, engineering, and math (STEM). Lanier High School opened in 2010, so this is our fifth year as a school; however, this is my first year teaching here. Before transferring to Lanier High School, I taught sixth grade Earth science at Lanier Middle School for eight years. Now, I have the awesome privilege of teaching many of my students a second time. It’s really fun to see how much they have grown up and matured since they were sixth graders.

I am looking forward to sharing what I learn with my students as I think my engineering students will gain insight into shipboard careers they may have never considered, especially as it relates to engineering. I think my technology students will get a chance to see how scientists collect and organize data using technology tools.

Although I teach chemistry and this research cruise is focusing on fisheries, I know my students will gain a new understanding of our oceans. Sampling the health, age, and quantity of different fish species with the NOAA scientists help us to measure the health of the oceans. Some of the big issues with the health of our oceans concern overfishing, human pollution, and ocean acidification. Ocean acidification refers to how the oceans take some of the extra carbon dioxide from the air and dissolve it into the water. This lowers the pH of the water making it more acidic, which can affect the health of the ocean’s inhabitants.

I applied to be a NOAA Teacher at Sea so I could learn more about our oceans in order to share this knowledge with my students. I have always been a hugely passionate about space and space exploration. I’ve had so many cool space opportunities like seeing shuttles and rocket launches, going to Space Camp, floating in microgravity, and most recently, helping our students talk to Reid Wiseman on the International Space Station via amateur radio.

Space is awesome and amazing, but we have an equally amazing frontier right here on own planet, our oceans. I want to be able to share with my students about the oceans with as much confidence and enthusiasm as I do about space, so I am extremely happy to be a Teacher at Sea so I can begin to glimpse all the science our oceans entail. I was also inspired to apply after hearing the stories from two Teacher at Sea Alumni Jennifer Goldner and Kaci Heins, who I met at Advanced Space Camp and now call dear friends.

Me as a child in Florida

I grew up on the west coast of Florida near the Gulf of Mexico. Just two miles from my house was a tiny commercial fishing village, Cortez. My childhood best friend lived in Cortez, so I spent many days running up and down the docks and sampling the fresh caught seafood. (Fresh smoked mullet was my absolute favorite!) This gave me a unique look at the importance of fishing to a community. I even had a chance to go out on a small boat with a commercial fisherman and a few of my friends one night and catch fish via nets. So even though space has always been my passion, I feel a connection to the ocean as well.

My cruise is on the Henry B. Bigelow, a NOAA ship outfitted for fisheries research. You can take a virtual tour of the Henry B. Bigelow including the science labs, and track the ship here.

I am part of Leg II of the Autumn Bottom Trawl. We will be taking samples of fish and other species of marine animals from the Mid-Atlantic to Southern New England to measure the abundance, health, and age of certain fish species. As part of the science team, I will work a twelve hour shift everyday – either from noon to midnight (day shift) or from midnight to noon (nigh shift). I will find out my assigned shift when I arrive to the ship.

Right now I am working on getting everything I need ready and thinking about packing. Since space on the ship is very valuable, I am trying to pack as lightly as possible. Some of the things I plan to bring with me are earplugs (I hear the engines are loud so it’s good to have these while sleeping), anti-nausea aids so I don’t get seasick, and cameras to document my trip. A couple of weeks ago, I received this cool package of items from the Teacher at Sea program. I’ll definitely be bringing the water bottle, shirt, and hat with me. The good thing is there are laundry facilities on board, so I don’t have to pack too many outfits. I also plan to bring a companion along with me. At my school, we are the Lanier Longhorns, so I will be bringing one of the plush longhorns along with me for this adventure. My question for you is which one? Toro or Tyson? You get to decide!

Who should join me at sea: Toro or Tyson?

At Lanier, our motto is Learn.Lead.Succeed. I cannot wait to learn new things on this trip and share them all with you! What things to you hope I will learn and share with you? Please leave your ideas in the comments. Until next time!

Science and Technology Log

 

We are now “on the road again” trawling. The nets were lowered at about 7:30 am. I was surprised by how small our catch has been. The scientists are not at all surprised. They said because of the time of year, many fish are in the estuaries spawning (reproducing). Today we have been on the edge of the continental shelf off the coast of Delaware and Virginia. When we get in closer, the scientists say we will have a lot more fish in our net.

It is fascinating how they are selecting sites for sampling.The sea floor needs to be fairly flat to pull a net across. We learn what the bottom is like using sonar. A multi-beam sonar on the bottom of the hull is in the center of the ship. There is also a single-beam sonar there. They serve two different purposes. The single-beam looks straight down the water column. It is like a really bright penlight. This shows what is in the water column such as fish and plankton. It also can reach greater depths since its light is stronger. The multi-beam is more like a floodlight. It spreads out over the bottom revealing all the different levels of the ground. These sonar beams bounce off the bottom and send the ship information. The crew  watches the sonar information and scouts for a good area to drop our nets. Of course, there are certain areas where samples need to be taken. They are trying to repeat a tow at the same time every year within a strata area. “So what is a strata?” I asked.

Geoff Shook, our survey technician, reads the information on the display

Strata lines are like lines on a topographic map on land. It is called a bathymetric map underwater. The lines on a bathymetric map are called strata lines. These are based on the different depths. The net needs to be pulled within the same strata at the same time each year. As long as a tow is within the strata the habitat is about the same. In order to get accurate population information, they must make at least two tows within a strata. Some of the strata are hundreds of square miles. Strata are the same depth range and habitat. Closer to the continental shelf, the strata are much narrower. Closer to shore, they are much wider. For example, strata 70 is 281 square nautical miles (nm). It is 55-110 m deep and is next to the shelf. However, strata 73 is closer to shore, is 2145 sq. nm, and is 27-55 m deep. Their habitats are different so random samples need to be taken within each.

So, I think of it like a chess board within a strata. If we want a random sample, we could drop a piece of soft clay from about a 1/2 m above the board. Where it hits is where we tow in that strata. Our first tow is at D5. The second piece of clay could fall on H2. So, there is where we would sample.

Then, when the ship is over top of the strata we will sample, it must find a safe area to tow which won’t tangle or break the net. You can’t get a sample with a broken net.

Notice the wires on the spools which haul the nets. On the first one the wire is tightly wrapped. On the second one the wire has a gap. This could lead it to break or more easily tangle. We are doing a deep tow tonight outside of the “normal” range of 366 m deep. However, it will not only give us new information, but will, hopefully, help rewrap the wire on the second spool so it will be tight. Have you ever tangled a loose fishing line on your reel? It is somewhat similar to that so we are trying to prevent this from happening later.

So, what have I been doing while waiting for a tow to complete? It depends. One time I told jokes with the scientists. Another I had a snack. Once I ate dinner. Right now, I’m working on my blog. Nap is not an option. I’ll explain that later.

It was a Win-Win Wednesday. We got some great fish by going deep, we explored some very deep water, the wire was rewound properly onto the spool, and we will have a shrimp fest tomorrow.

Meet the Crew

Luke Staiger, 2nd Cook

Luke Staiger, 2nd Cook

The old adage “an army runs on its stomach” holds true for a research vessel. Meet Luke Staiger, our 2nd cook. Luke is with the Bigelow on temporary assignment from the Reuben Lasker  in San Diego. NOAA members get moved around short term as needed. Luke has been with NOAA for 12 years. He has been cooking since he was a kid. His most important tool is an 8″ all purpose knife. It must be sharp and long-handled. If he could invent the perfect tool for the job, what do you suppose it would be? That’s right, a knife that is comfortable to hold all day.

Luke worked in a buffet restaurant so this is the perfect situation for him since it’s all buffet. He worked his way up to cook after doing other jobs at the restaurant. I’m looking forward to a breakfast that he prepares since cooking breakfast is his favorite.

Luke recognizes how important the work is that NOAA does. We need to preserve our resources, such as water, he says. NOAA keeps an eye on things so we don’t lose sight of what matters. When not on a boat, Luke enjoys fixing up cars, especially adding stereo systems. Luke has an easy going personality and a ready smile, making it pleasant to work with him.

How did he find NOAA? Similar to others that I have interviewed, he looked online. NOAA has good benefits, you get to travel, and the experience is good. His advice to my students is to gain lots of experience in your field, even if it’s just volunteering. You will find work if you do a good job and have a lot of experience.

Personal Log

Remember I said I won’t get a nap during my 20 minutes between tows? It is interesting how our stateroom (cabin/bedroom) works. There are four of us in our stateroom. When I leave to go to work, I cannot go back until the end of my watch. I carry everything with me so it is like the private room for two other women. Then I only have one room mate. We get the room for 12 hours. There are curtains around our beds and we wear earplugs. I hardly know that the other scientist on my watch, Lacey, is even there. All I do is check to see if her curtain is closed. That means, “I’m asleep.”

Did You Know?

Did you know that there is an anchor-cleaning device onboard the ship? It sprays salt water at 150 psi (pounds per square inch). The anchor gets pretty dirty sitting on the ocean floor when we are at anchor. They don’t want all that dirt on the ship in the anchor locker, so it gets cleaned. A clean ship is a happy ship.

Question of the Day

Why would different depths affect which fish live there?

Vocabulary Word

Sonoluminescence. This is short bursts of light from imploding bubbles in water (or in a liquid) when excited (moved around) by sound. A mantis shrimp is capable of sonoluminescence because the high speed of its front legs is capable of creating and rapidly shrinking air bubbles. The bubble looks like a spark underwater with no fire.

Something to Think About

If we don’t preserve our fisheries, which is what NOAA is researching, soon there won’t be any fish.

Challenge Yourself

We used a deep-water protocol, which is between 183 and 366 m. If you are fishing in a strata that is 200 feet deep, would you fall in the deep-water protocol?

Animals Seen Today

Here are pictures of what we saw today in our really deep water trawl.

Science and Technology Log

I have the privilege of working with the science team on Leg II of the Autumn Bottom Trawl Survey aboard the NOAA Ship Henry B. Bigelow from September 27 – October 7, 2010. We left port on Monday, September 27 and have been conducting the survey in the waters of Southern New England.

Processing Fish

Processing Fish

Fisheries surveys are conducted every spring and autumn in order to determine the numbers, ages, genders and locations of species that are commonly caught by the commercial fishing industry. The surveys are also carried out to monitor changes in the ecosystem and to collect data for other research. The scientists working on this leg of the survey are from Alaska, Korea, and New England. This ship works around the clock, therefore, we are divided into a day watch and a night watch, and we are all under the direction of the Chief Scientist, Stacy Rowe. I’m on the day watch, so my team processes fish from 12:00 noon until 12:00 midnight.

In order to collect a sample of fish, our ship drags a net for twenty minutes in areas that have been randomly selected before the cruise began. After the “tow,” the net is lifted onto the boat, and the fish are put in a large area to await sorting. The fish move down a conveyor belt, and we sort the fish by putting the different types into buckets and baskets. Once, the catch has been sorted, we move the buckets onto a conveyor belt, which moves them to stations for data collection.

Measuring fish

Measuring fish

Two people work at a station. One is a “Cutter” and the other is a “Recorder.” The cutter measures the length and weight of the selected species of fish on a “fishboard.” This data is automatically entered into the computer system. Depending on the species, the cutter might also be required to take an age sample or a stomach sample. Age is determined by collecting scales or an otolith (sometimes called an ear bone), depending on the species. The cutter removes these and the recorder puts them in a bar-coded envelope to send back to the lab for later study. The cutter also removes the stomach, cuts it open, and identifies what the fish has eaten, how much, and how digested it is. All of this information is entered into the computer for later analysis.

The information gathered during this cruise will give NOAA and other organizations valuable information about the health of the fish species and their ecosystem.

Personal Log

I arrived the night before we left port, and I was able to spend the night on the boat. My stateroom sleeps two people in bunk beds, and each person has a locker in which to stow our belongings. The stateroom also has a bathroom with a shower. Right across the hall is the scientist’s lounge. It has two computers, a television, many books, and games. This is where we sometimes spend our time while we are waiting for a tow to come in.

We spent much of the first day waiting to leave port. Once underway, some tests were conducted on the nets, and my Watch Chief showed me pictures of some of the common species we would see, explaining how to identify them. We began processing fish today. The first time the fish came down the conveyor belt, I was nervous that I wouldn’t know what to do with them. It worked out fine because I was at the end of the conveyor belt, so I only had to separate the two smallest fish, Scup and Butterfish, and Loligo Squid. After my first try at processing, I felt much more confident, and I even was able to tell the difference between Summer and Winter Flounders. One faces to the right and the other faces to the left!
