Science and Technology Log
On the ship, there are two science watches: noon to midnight (day shift) and midnight to noon (night shift). I am assigned to the day shift. We left port late Tuesday afternoon, but we made it to our first trawl site a few hours later. When the nets brought back our first haul, I had a crash course in sorting through the fish. The fish come down and conveyor belt from the back deck to the wet lab. In the wet lab, the first thing we do is sort through the fish. The more experienced scientists are at the front sorting through the larger species and sometimes the more abundant ones. The largest species of fish go in large baskets, the medium sized ones go into large buckets, and the smaller ones go into smaller buckets. Each basket or bucket only has one species in it. During our first trawl, there was a smaller amount of fish to sort through, but we had a lot more fish the second trawl. It took us longer to sort through the larger fish.
Once the fish are sorted, we go to our cutter/recorder stations. At our stations, we sort through the buckets of fish one by one. Right now, I am a recorder. This means that I record the information about each fish into the computer. It’s a really cool computer system. First, the bucket it scanned. On the computer screen, a message pops up to tell us what type of fish should be in the bucket. If that is what we have, we say “Yes” to the prompt and continue. Then, we dump the contents of the bucket into a well waiting for inspection. The cutter pulls the fish out, one by one, and begins to take measurements. The first measurement is usually length. The tool for taking the measurements is integrated into the computer system. The fish are laid out on the ruler, and a sensor is tapped at the end of the fish. This sends the fish’s measurement to the computer. The Fish Measuring Board is a magnetic system. The tool that we use to measure the fish is a magnet. The board is calibrated so that when the magnet touches a specific area of the board, it will read the appropriate length. The computer then tells us what measurement to take next. Usually it is weight. On the other side of the Fish Measuring Board is the scale for the larger fish. There is also a small scale for smaller specimens. When the weight is recorded, the computer then prompts for additional measurements which are taken from the fish. During our second trawl, we worked up a bucket of summer flounder. One of the summer flounder was huge! I had not seen a flounder that big before!
One of the things that has really impressed me so far is the integration of the science and the technology. The computer system that records measurements is integrated into the ruler and scale right at the work bench (the fish measuring board). When we take samples from the specimen, a label is printed right at the station, and the sample is placed into either an envelope, zip bag, or jar for further handling. It reminds me of how technology makes the job of science more streamlined. I can’t imagine how long it would take for the processing and sampling of the fish if we had to take all of the measurements by hand! Technology is a valuable tool for scientists at sea.
Careers at Sea
We left port on Tuesday, September 23. Before we left, I had a chance to explore the ship and ran into chief engineer Craig Moran. He sent me to the engine room for a tour, and I met John Hohmann. John is the first engineer on the Henry Bigelow. He showed me around the engine room including the generators, the water system, and the shaft to the propeller. It was pretty quiet in the engine room since we hadn’t left yet, but it is a loud, warm place when the ship is at sea.
I had a chance to chat with John about his background in engineering. He has a specialization in marine engineering. Marine engineers really need to be a jack-of-all-trades when we are out at sea. If anything is not working right on the ship, they are called out to fix it. This can include any of the machinery in the engine room, the electrical systems, the water purification system, and even fixing the cooking equipment in the galley! Life at sea can be demanding as they can be called at any time day or night to fix an integral piece of machinery. However, engineers generally work 30 days at sea and then are home for 30 days. One thing John wanted you all to know is that there will always be jobs for engineers. If you are interested in marine engineering, it can help you travel the world. John has been all over the world to many interesting countries. The other thing that I found interesting is that he says you need to be able read and follow instruction manuals in order to fix an issue. He also said an essential skill for an engineer is problem solving. Marine engineering entails a lot more than I had initially thought, and it is really cool to be able to talk to John and learn about marine engineering from him first hand.
I arrived to the ship Monday evening (September 22). Since the ship wasn’t scheduled to leave port until the next day, most of the team was not on board yet. I was able to find my stateroom and get settled in. Tuesday, things started to pick up on ship. There was a dive at 9:00 to check the hull of the ship, so I had a chance to watch the divers slide into the water and later climb back out. The rest of the science team arrived just in time for lunch. I then had time to explore the ship (I found the important places: the laundry room and the gym!), and get to know the science team a little bit better. The ship started undocking around 16:00 (4:00 pm), and we were on our way to sea. We went up to the flying bridge, the highest deck on the ship, as we left Rhode Island. It was beautiful up there as we passed by Newport and the surrounding areas. There is an old lighthouse that is now used for event spaces, and a house built up on a small rocky island. At 17:00, it was dinner time. We eat our meals in the mess, and the meals are prepared in the galley. I knew I needed to eat a good meal because my watch for the night officially started at 18:00 and would last until 24:00.
The sea was pretty calm yesterday, so it was a good introduction to the ways of life on a ship. So far, I have not had any trouble adjusting to life onboard ship. I was worried about sea-sickness, but I came prepared and have felt great so far. A lot of the crew have mentioned that I should be fine, and that I’ve already found my sea legs. I think perhaps I have found my sea stomach but not my sea legs! I do periodically lose my balance when walking through the corridors. Thankfully, there are handrails everywhere to catch my balance just in case. Maybe I’ll find my sea legs in a few more days, but I am pretty clumsy even on land!
Safety drills are also an important part of sea life. Each person has their own immersion suit and personal flotation device (PFD). These are in case we have to abandon ship. We need to be able to put our immersion suit on in 60 seconds. The immersion suit is kind of like a wet suit, but it has lights on it and other tools. There are also lifeboats on board. There are three types of emergencies we need to be prepared for: abandon ship, man overboard, and fire/other emergency. Just like we have fire drills at school to help us know where to go in the case of a fire, these drills help us prepare for emergencies.
Did You Know?
You can tell a summer flounder from a winter flounder by the side the eyes are on the fish. You look at the fish as if it were swimming up right. Summer flounder eyes are on the left, and winter flounder eyes are on the right. Summer flounder are called left eyed, and winter flounder are called right eyed.
