Me in Front of the Southwest Fisheries Building

Yesterday, Anne-Marie and I were given a tour of the NOAA facilities in Pascagoula. In the new building they house several different divisions; Southeast Marine Fisheries Unit, Seafood Inspection and Documentation and Approval Center. Kevin Rademacher our Chief Scientist showed us around. The labs in the Marine Fisheries unit take what is being done on the vessels and use it for research. They run many different types of research on the ships. Beside the Pisces, there are two other ships that are run out of Pascagoula; Oregon II, and The Gordan Gunter.

On one of the floors were the Seafood Inspection labs. They bring in fish from different areas and test it. In one lab they had a set of partitions up which were the tasting areas. An example of what they have done in the past that Kevin gave us was a restaurant bought some red snapper. They brought it to the lab where they cooked in clear Pyrex containers then they smelled, checked the consistency, and tasted the fish. They discovered that the fish was not really snapper! Right now due to the oil spill they are mainly focusing on the fish that we bring in on our survey. We are required to save 10 fish out of every trap we bring up so that they can have a baseline testing of fish from an area before being it has been impacted by the oil spill.

Another floor of the building is the science labs. We walked through the plankton lab, where each person had their own station with a computer and a high powered microscope. They had several different samples out that were labeled. Just like our trip in the 6th grade they used nets with different size holes to catch different types of plankton. Another lab was called the Age and Growth lab. Here is a picture of shark vertebrae they were preparing for aging.

Today we are not working on the Reef Fish survey. Our Chief Scientist Kevin Radechamer wanted to do some mapping of an area called Sackett Bank which is south of Louisiana. The mapping they had done before did not give them an accurate depiction of the sea floor and now they have new technology. They are using an acoustic system called ME70. This system has 27 beams that run in a 120 degree swath. With the technology they had before they were only able to see 1 meter “bumps” on the surface now they can see to within a ½ meter. The white line that you can barely see shows the surface of the seafloor. The red is sand or mud that is on the bottom, as the red gets thinner and darker it is showing the harder rock that is below. As the sound waves go down they bounce back and we are able to see any see critters that are down there. Most of what you can see in the picture is plankton but occasionally you can see fish as well. This is a before and after shot of the two types of mapping. In one the map technology was guessing what was in between the bands. This information will give scientists new information about the seafloor.

Personal Log:

I’m finally here! The last two days were very exciting. When we got to the ship it was 7:00ish and most of the ship’s crew were out and about, so we had the ship to ourselves. We wandered around taking pictures and investigating. I only went on an “adventure” (lost my way) twice. Everywhere you turn there is a doorway, hatch or stairwell. I was awed by the amount of technology that they have on board. There are computer labs on almost every floor. I am envious of the color printer! Ann Marie and I are sharing a state room. It’s fantastic! The crew takes pride in what they do and it is very obvious, our beds even had mints on them. We have a T.V. and an internet connection in our room. I don’t plan on spending a lot of time in there but it is pretty fabulous!

We left port yesterday and headed south. The scientists and teachers stayed on the fly deck as we moved closer to the Gulf. As we were leaving you could see what impact the oil spill has had on the Mississippi Coast and on the Barrier Islands.

As a result of the tropical storm over the weekend there were some pretty high swells. We had waves from 6 to 8 ft. The ship was rocking pretty badly. After our Safety Meeting where we were told about all of the safety precautions and the rules. No matter where you go there are rules. Including.. No wearing tank tops to the galley and NO sitting in the captains chair. After the safety meeting the rolling was beginning to get to us so Anne Marie and I took to our bunks. I didn’t get sick! I did however go to sleep at 7:30.

Today we have spent most of the day wandering around the ship and talking to the many different crew members on board. Oh.. and we had a fire drill. The fire drill was a lot like having one at school, the bell rang we walked to our area and then we sat for awhile. The next drill was much more exciting. We had an Abandon Ship Drill! We had to grab a long sleeve t-shirt, a hat, pants, our Gumby suit, and a life jacket. It was a lot of stuff to carry with us! Everyone met out on the deck and I was introduced to Chief Marine Engineer Garrett who would be in charge of getting me where I needed to be in an emergency. As a first timer I was required to get into my Gumby suit. Yes, for those of you old enough to remember they are named after Gumby and Pokey. This would definitely not be my choice of a fashionable outfit. To get into it you have to lay the suit down on the ground and climb in like a sleeping bag. Then you zip it up!

Everywhere you look in the Gulf you see oil rigs or tankers moving away or to an oil rig. We passed the disaster site this morning but we were 9 miles away so we did not see any oil or much of anything. In fact I haven’t seen oil yet, which is a good thing. The interesting thing that has come about for our trip as a result of the spill is the two bird experts, Scott and Ron. The birders were hired to look for pelagic birds, those that spend most of their lives at sea. Fish and Wildlife hired one, and the other is here for BP. They are looking to see if any pelagic birds have oil on them or if they find any dead birds. So far, in the four hour s they watched this morning they saw 11 birds. Listening to them talk has been fascinating!

This was the sunset tonight. I’m heading in with tea in hand to try and upload the rest of my pictures. I’m ready for tomorrow! Kevin said we will start a half hour after sunrise so I’ll be up bright and early! Let’s do it! Bring on the giant fish and things for me to get dirty with!

Science and Technology Log

As you can tell from our previous blogs, we spend a lot of our time on the Oregon II counting, measuring and weighing our catch and loading the data into FSCS. These data are critical to NOAA and the states in managing fish stocks and the Gulf ecosystem. In addition to knowing population size, weights, and lengths of individuals it’s also important to know the sex of the organisms. Information on the male:female ratio helps NOAA and the states assess the ability of the population to reproduce, and to establish sustainable catch levels for commercial fishing.

But how do you determine the sex of marine organisms? For most fish and invertebrates you can only tell the sex by internal anatomy, which almost always requires cutting the animal open. This is time consuming and not always practical when we have a large catch to process and other tasks take priority, such as preparing samples to be analyzed for contamination from the oil spill which is our top priority right now.

For some organisms, however, sex can be determined externally. One of the things we’ve learned in the past week is how to determine the sex of shrimp, flatfish, crabs, sharks, skates and rays. Here’s how:

Shrimp: the males have a pair of claspers (called petasma) on their first set of legs.The petasma are absent in females. The males use the petasma during mating to grasp the female and transfer the sperm sac.

Shrimp M — Male – arrows show the petasma

Crabs: On most crab species females have wide plates curving around the rear of the abdomen, while males have a long narrow plate or plates. On females, the eggs develop under the curved plate.

Flatfish: When you hold a flatfish up to the light you can see through it, which enables you to do an internal examination without cutting it open. On female flatfish, the gonad extends in a dark red, curved wedge which is absent in the male.

Flatfish F — Female showing long curved gonad

Flatfish M — Male – long gonad is absent

Sharks, skates and rays. Males have external claspers that they use in mating, while in females the cloaca is smooth and claspers are absent.

Shark M — Male Angel shark – arrows point to claspers

Shark F — Female Angel shark – claspers are absent

Personal Log

A tropical depression moved through the Gulf yesterday evening, making it too rough and windy to fish. So instead of counting, measuring and loading data into FSCS, my watchmates and I cleaned the lab, secured our gear, and headed up to the lounge to watch Shutter Island on the large-screen TV. Last night my bunk was like a roller coaster, tossing me from side-to-side and head-to-toe as the ship rolled and pitched in the big swells. Today has been a slow day for the scientists on board, waiting for the storm to pass so we can start trawling again, while the crew and officers remain as busy as ever.

Science and Technology Log

Since setting out on Friday we’ve headed south along the Gulf coast of Texas almost to the Mexican border, and now we’re heading back north but farther offshore, in deeper water. As a result our trawls are pulling up a deep-water assemblage of species different from those we saw in shallower waters a few days ago. There is still no sign of oil in this part of the Gulf, but we’re still taking samples of fish and shrimp for analysis to make sure there’s no contamination here from the BP- Deepwater Horizon oil spill.

Ten-foot seas are predicted for tonight so we’re heading north along the Texas coast, away from the storm, and we’ve put away the fishing gear until it gets calmer.

Last log we talked about FSCS (Fisheries Scientific Computer System). So what is it, how is it used, and what is so great about it?

FSCS, commonly pronounced ‘fiscus’, is an automated system for recording the massive amount of biological and oceanographic data generated 24 hours a day by NOAA scientists during fisheries surveys. During a trawl survey, fish and invertebrates from each haul are sorted, counted and weighed by species. Scientists record data from individual fish, such as sex, weight, length and even stomach contents, resulting in tens of thousands of new data points every day. Before NOAA rolled out FSCS in 2001 aboard the NOAA ship Albatross IV, scientists recorded all data by hand, an incredibly tedious process. With FSCS, however, data are recorded digitally which is much faster, allows integration of biological and oceanographic data, and enables NOAA to obtain critical real-time information to assess and manage the health of the marine ecosystem and individual fish stocks.

Kim FSCS — Here I am entering data at one of the two FSCS stations aboard the Oregon II.

FSCS uses a Limnoterra FMB4 (fish measuring board) which has a magnetic pen to upload the length of an organism within a millimeter (mm) range, and computer software that annotates all of the data with information such as length, mass, sex, etc. The software also lists species scientific names which can be selected into a short list so scientists can more quickly select organisms from a list. Special labels can be printed for specimen samples that are to be shipped to other scientists and to the National Seafood Inspection Laboratory which was started in Pascagoula, MS.

Personal Blog:

My last shift Wednesday 0000-1200 hrs. was very good. I was over my sea sickness, I had 8 hours straight of good sleep, and we did a good job on night shift with keeping up with our stations.

This photo shows a brown shrimp being measured for length. The magnetic pen to the right of the shrimp marks the spot, the measurement is then sent to the computer.

Our chef, Walter has been feeding us very well. The portions are so big that I can’t clean my plate. As you can guess, we have had shrimp several times, and after measuring and identifying shrimp every night for 12 hours I don’t know if I will be that anxious to eat shrimp for a while!My Thursday 0000-1200 shift was canceled due to weather as mentioned in the earlier part of today’s blog. So now I am catching up on emails, blogs, and laundry. We should be trawling again within the next 24 hours.

Where am I?
Life aboard a ship is difficult to comprehend until you have experienced it first hand. If you forget something, oh well, and you live with what you have for the duration of your leg. Planning ahead is huge for a mission to the Bering Sea! (Sound familiar students?!) Life at sea can be much slower than I think people believe it to be. On this particular type of cruise, much of the day is spent waiting, watching, and analyzing information. While everyone has their job, some of those jobs require patience and flexibility.

brustolon_log5_img_1 — NOAA Ship Oscar Dyson anchored in Dutch Harbor

What happened?

Ever have that moment when a demonstration fails, the cool lab you worked so hard on doesn’t work, there’s a schedule change thrown into your day, or maybe that special dinner you were planning didn’t taste right? It happens on the boat too! You have to be prepared and understand that it is going to happen. Equipment failure, human error; they all happen on board. I arrived in Dutch Harbor on June 26th and we were scheduled for departure on June 27th. There was a broken crank shaft in one of the large generators so our departure from Dutch Harbor was an educated guess at best. Without the generator, we would be in short supply of fresh water for a ship holding 39 people until July 16th. There wasn’t anything that we could do so we took advantage of being in Dutch Harbor for a couple of extra days until we departed on June 29th. Maybe the copper wire was cut before it reached the bottom on an XBT or there was a hole in the trawl net that needed to be mended. That part of life on board is no different than any other environment.

It’s an albatross, an orca, a tree?

Talk about patience…the mammal observers have lots of it. They are on watch constantly looking along the horizon for blowholes and other signs of mammalian life. When observations are slow, anything in the water can become exciting. Earlier this week while I was on the bridge, the mammal observers called down from their observation deck to the bridge because there was an object in the water that we were getting closer to. You could feel the excitement from everyone growing as this magnificent object grew closer. We got our cameras ready because this could be “the” picture of the trip and positioned ourselves to take the shot of our lives. As we approached this rather large piece of unidentified matter, we realized that it was a piece of driftwood with murres hanging out on it. At this point, the adrenaline rushed out of me and laughter took over. None of us could believe how excited we became and how let down we were to find out it wasn’t a mammal at all. Back to the observation deck!

brustolon_log5_img_2 — Looking toward the horizon through the “Big Eye”

You can’t force the fish!

My primary job on this boat is to help with the fish surveying. Using the acoustics helps decide when the trawl nets are deployed for fishing. In order for fishing to occur there needs to be at least 2-3 miles of pollock showing up on the transducer screens. Weather also plays a role on what we see on the transducers. We have been very pleased with the weather so far; although it has been foggy, that usually means calmer seas. Later in the week, the weather is supposed to get dicey. When this happens there is a chance that it will be too rough to fish even if we do see the pollock. Look for my journal on weather after the weekend! Since the start of our journey we have fished three times during my shift and deployed the Methot a few times. When we are not fishing we find other things to keep us busy. Some people are analyzing data, checking equipment, or if you are a teacher at sea, you may be documenting all of your experiences. I have never taken so many pictures! The down time gives me a chance to talk to others on the boat to see what other operations are happening. As my friends and family know, I have a hard time sitting still. This is the perfect place for me to be because I have no choice but to slow my pace! It’s REALLY hard, but I think I am doing a pretty good job!

What shift are you working?

Aside from the flexibility needed to work on the ship, you also need to be flexible and patient just to live on board. Remember, you can’t just leave the ship when you need a break! The boat runs 24/7 so there are lots of shifts on the boat. To give you an idea you may be on watch for 4 hours in the dead of the night, or you may be observing mammals from sunrise to sunset. I was lucky to land the 12 hour shift from 0400-1600, but the other fisheries crew comes on for the remaining 12 hours of the day. I say this because with a full crew of 39 people on board and with everyone working different shifts, there is etiquette on board a vessel. If you and your roommate do not have the same shift, it is the unwritten rule not to enter the room while they are sleeping. That means you need to take everything with you for that shift. Not everyone eats during the allotted times that the mess hall is open so food is often set aside so everyone can have their meals regardless of what shift they work. Taking showers need to be short because everyone would like to take a hot shower after 12 hours of working. Appropriate volume is important because there may be people sleeping in the stateroom next to you and you don’t want to wake them while they are trying to sleep when off shift (remember inside voices!). It makes you very aware of your surroundings. I absolutely lucked out because Rebecca (the other TAS) and I have the same shift and same schedule. We have it much easier than most people on the boat that have opposite shifts.

Can anybody hear me?

Need time away from the hustle and bustle of life back on land? Need to take a break from your TV, cell phone, blackberry, I phone, and the internet…the Bering Sea is the place for you! Even though there is a phone on board that allows you to call off the ship, it is extremely expensive so it is definitely not for everyday use. Phones don’t work here so you can save the batteries in your cell phone or I phone for home. Most of them actually don’t even work on Dutch Harbor either. As far as the internet is concerned, that’s a little trickier. As you may have noticed, my journals took a while to be posted. It is very difficult to send information via internet from the Oscar Dyson. If we are traveling on a northern transect, we may not get internet the entire time. The transect itself could take 2 days to complete running at 12 knots! If we are turning or heading south, we may get lucky for a while. Therefore it takes time to get all the information and pictures sent just to be posted. It is very hard to be patient because I want everyone to know what’s happening and all the cool things we have been doing. Internet is sporadic at best, but keep the emails coming! It is nice to hear from everyone back home!

I’m enjoying my 12-hour shifts processing fish, shrimp and invertebrates on theOregon II. Our noon-to-midnight watch is working well together and starting to bond.

Day Watch Fish Lab — My watch-mates in the Oregon II wet lab.

I’m seeing lots of very cool marine life that we’re hauling up from the bottom of the Gulf with our trawling net. Here are just a few of the things I’ve seen in the past two days:

Dwarf frogfish - Antennarius radiosus — Singlespot frogfish – Antennarius radiosus.

Note the lure on its snout.
