fish board

This is the fish board we use for measuring each critter in our sample.

Now that we’ve talked about how we collect, sort, and measure our catch, let’s take a closer look at the way we measure, weigh and sex our critters.

When measuring the critters, we use a fish board that is activated by a magnetic wand to measure the animal to the nearest millimeter.

When the fish is placed on the measuring line, we touch the magnetic wand to the board and the length is recorded into our computer program, FSCS (Fisheries Scientific Computer System).

Depending on the type of fish we catch, there are different ways to measure it.

scorpion fish total legnth

Here is Alex measuring the total length of our scorpion fish.

total length measurement

This is how we would measure a fish for its standard length, which is just before the tail fin starts.

fork length measure

This is how we would measure a fish for its fork length.

Cutlass measuring

For fish such as this cutlassfish, we measure the length from the head down to the anus, as seen here on the board.

When we are done measuring, the fish is placed on a scale to determine its weight to the nearest gram. When we confirm the weight of the fish, that weight is automatically put in the computer for us- no need to enter it manually.

Our last task is to determine the sex of the fish. For many fish, this is done by making an incision in the belly of the fish from their anus to their pelvic fins. It’s easiest to determine the sex when it is a female with eggs. In the males, you can see milt, or sperm, which is a milky white color.

This is a male fish. Notice the arrow pointing to the testes.

female fish

Here we have a female fish.

For the flatfish, you can see the female’s ovaries when you hold the fish up to the light. Males lack this feature.

male flat fish

This is a male flat fish.

female flat fish

Here we have a female flat fish- notice her gonads.

Because we were catching quite a few shrimp earlier in the leg, I got pretty good at sexing the shrimp. Remember, we take samples of 200 for each type of shrimp, and we often had more than one type of shrimp in each trawl. Male shrimp have a pestama on their first pleura to attach onto the females. The females are lacking this part. Although it’s not necessarily an indication of sex, on average the female shrimp tend to be larger than the males.

Here is a male shrimp.

female shrimp

Here we have a female shrimp, which is lacking a pestama.

You  know from my previous post what we do with the data we gather from the shrimp, but what about the other fish? With the other fish and critters we catch, we use the data to compare the distribution across the Gulf and to compare it to the historical data we’ve collected in the past to look for trends and changes.

Sometimes scientists also have special requests for samples of a certain species. Some scientists are doing diet studies to learn more about what certain types of fish eat.  Other studies include: species verification, geographic range extensions, age and growth, and distribution. Through our program, we have the ability to create tags for the scientists requesting the samples, allowing us to bag and freeze them to send to labs when we return to land.

showers

There are 2 communal showers for our use on the bottom deck.

Personal Log

I’ve had a few people ask me what the living quarters and the food is like on the ship, so I wandered around the ship with my camera the other day to snap some shots of the inside of the Oregon II. There are 17 staterooms on board. Most of the staterooms are doubles, such as mine, and are equipped with bunk beds to sleep on. It makes me reminisce of my days at camp, as it’s been a while since I’ve slept on a bunk bed! We have a sink and some cabinets to store our belongings. Once a week they do room inspections to ensure our rooms are neat and orderly. Most importantly, they want to make sure that our belongings are put away. If we hit rough waters, something such as a water bottle could become a dangerous projectile.

Walter, doing what he loves

My stateroom is on the bottom deck, where there are also communal showers and toilets for us to use. We can do our laundry down here, providing the seas aren’t too rough. Most of the staterooms are on this bottom deck, as the upper 2 levels are the “living areas” of the ship. On the main deck is the galley, where we eat all our meals, or where we head to when we are trying to make it through the shift to grab a snack or a cup of coffee. This tends to be right around 4:30/5:00am for me, especially when we aren’t too busy. I’ve gotten used to the night shift now, but it still can be tiring, especially when we have a long wait in between stations. Our stewards take very good care of us, and there is always something to snack on. Meals have been pretty tasty too, with plenty of fresh seafood. My favorite!

chart room

On the top deck we have the lounge, a place where we hang out in between shifts. We have quite a good movie selection on board, but to be honest we haven’t had the time to take advantage of it. They’ve kept us very busy on our shifts so far, and today is one of the first days we’ve had a lot of downtime. Outside we also have some workout equipment- a bike and a rowing machine- to use on our off time. When you set the rowing machine out on deck, it’s almost like you are rowing right on the ocean!

dive

The other day, 2 of the NOAA Corps officers, LT Harris and LT Miller (who is also the XO for the Oregon II) and 2 of the deck crew, Chris and Tim, got ready to go out on a dive. NOAA Corps officers need to do a dive once a month to keep up their certification. Sometimes they may need to fix something that is wrong with the boat, and other dives are to practice certain dive skills. They dove in the Flower Gardens, which is a national marine sanctuary with a wide diversity of sea life. I was hoping they’d see a whale shark, but no such luck. We stopped all operations for the duration of their dive.

Favorite Catch of the Day: Here are a few cool critters we pulled up today. In addition to these critters, we also started seeing some sea stars, lots of scallops, and a variety of shells.

Net Tow

That's me tending the Neuston net as it's being towed aside the R/V Walton Smith.

One of the many experiments we are doing on board is to learn about a plant that grows in the ocean called Sargassum. This tan plant floats near the surface and along in the current. It grows throughout the world’s topical seas. It can grow into large mats the and can be as large as boats and ships. Sargassum provides an environment for distinctive and plants and animals that are not found other places. These ecosystem rafts harbor many different organisms.

On the third stop of the CTD cycle we drag a Neuston net along side of the boat. For 1/2 hour, night or day, the boat takes a slow turn as we drag the net along the surface as we collect samples.  Almost all of the animals below are what we have found in the Neuston net.

We’ll haul in the net and remove the contents. We’ll first try to get all of the animals out. The animals usually don’t survive but every once in a while we can save them (see below for some of the animals we captured with the net).

We’ll next sort the plant life that we collect in the net. Of course we are looking for Sargassum, so we will separate out all of the sargassum.

So, how do you measure what you get? We measure it by volume much like our mom’s measure shortening for cookies. We will fill up a graduated cylinder part way with water, put the samples from the net into the cylinder and then measure how much water they displace.

For example, if we put 2500 ml of water in the graduated cylinder, then put Sargassum in the cylinder, the water level now measures 5500 ml . We then know that there are 3000 ml  (5500 ml – 2500 ml = 3000 ml) of Sargassum by volume measure.

Everything we collect from the net, we measure and record.

Personal Log — Animals I’ve seen

  • Flying Fish— Yes, believe it or not, there are fish that fly. Last night as were preparing to lower the CTD, I noticed silvery-blue streaks in the water. One of the scientists with me explained that they are Flying Fish (Exocoetidae) and the lights of our vessel attracts them and many other types of fish to the surface at night. As soon as she explained this, one of them shot out of the water and glided about a meter and ducked back into the water. Read more about Flying Fish here.
  • Rock Fish

    This fish was found as we unloaded the Moch net.

    Rock Fish — Each time we drag the Moch Net for the Sargassum survey, we can expect interesting things. Last night we captured a type of Rock Fish.

  • Spotted Eel — We also found an eel that has white spots. I tried my best to see if I could more specifically identify it. We have saved it in an aquarium on board the R/V Walton Smith.
  • Mystery Fish

    Help identify this mystery fish. Make a comment below if you think you know what it is.

    Mystery Fish — This fish has many of us stumped. It has a long nose but when the fish opens its mouth, you can see that the pointy part is connected to its lower jaw. Put your investigative skills to use and help me identify the fish. Post a comment if you think you know what it is. For an enlarged view, click here.

  • Moon Jellies — Many people call them Jelly Fish but actually they don’t belong to the fish family at all. They don’t even have a backbone. When we carefully picked these animals up, with gloves on of course, it feels like picking up Jello with your hands; it just slips through your fingers. You can find more about Moon Jellies, Aurelia aurita, at the Monterey Bay Aquarium. You can also find general information about Jellyfish at National Geographic Kids.
  • Sharptail eel

    This eel was found when we were collecting Sargassum.

    Sharptail eel — It’s about half a meter in length and squirms all over. The scientist studying the Sargassum, has saved it in an aquarium so we can observe it. Its scientific name is Myrichthys breviceps.

  • Honey Bee — Believe it or not a honey bee joined us. There was no land in view and a honey bee landed on me. The wind must have blown the bee to sea and it was probably very happy to find a place to land that was not wet.
  • Porpoise — We also call these dolphins. Sometimes a pod of porpoises will get curious and  investigate our boat. They will circle us, swim along side and even ride our bow wave.

Dear Blog Aficionados,

Cumulonimbus clouds on the horizon

Cumulonimbus clouds on the horizon

Today I saw two different types of sea turtles, a bunch of jelly fishes, dolphins, and the people on the boat. It has been a beautiful day and I am trying to rest up because it is going to be a long day and night of setting up traps and categorizing fish. The weather here is hot and somewhat clear. I believe there is a high pressure system over us at this time. However, when you look over the coast of Florida there are these extremely large rain clouds, which are cumulonimbus clouds, rising into the sky.  The sky is clear all around the boat and suddenly there is this large mass of clouds. Last night was very memorable when a lightning storm intermittently made this region glow. I stood at the bow, stern, port side, or starboard side in wonder of this spectacle. (Hopefully I will learn locations by the end of the trip.)

The last time I wrote about myself I was a bit nauseated, which does not do much for the self-esteem. My name is Walter Charuba and I have been teaching for a number of years. (This is code for not wanting to give you a specific number.) I am lucky to work for Grosse Pointe Schools at a great school called Brownell Middle School. I am also lucky to live in Grosse Pointe Farms and I actually live about a half a block from my school. This makes my carbon footprint sort of a toe print.

I have won numerous teaching awards such as Best Dressed Teacher, Youngest Looking Teacher (I hand out treats for this one.) and Teacher Who Lives Closest to School. After filling out the forms and passing the physical, and these examples from my wonderful resume, I was lucky enough to be chosen for the NOAA Teacher at Sea Program. Seriously, I do feel very fortunate to be part of this program and learning from these scientists.

You now may be wondering what exactly am I doing on this wonderful boat called the Savannah?  (If you are not wondering about it, could you change your focus, because this concerns my next paragraph!)  I am assisting in a very large fisheries survey by setting up fish traps, deploying of fish traps, and collecting data about the fish. When laid flat, the fish traps are six by five feet across and two feet deep. In these traps we place 24 menhaden bait fish, which are a close relative to the herring, if that means anything to you.

Then 5 to 6 traps are dropped off the back of the boat with special cameras to record activity around the trap. These cameras take about ninety minutes of footage. The traps also have two buoys connected to them to assist in collection. The areas where the traps are dropped are designated by the Chief Scientist, Warren Mitchell. Using sonar, Warren has to consider depth, currents, distance, topography, and a time schedule. Not an easy decision.

Setting the fish traps with bait

Setting the fish traps with bait

Science Watch Chiefs, Sarah Goldman and David Berrane, have to make certain the drop offs go smoothly. They have to make certain there are enough bait in the traps, and if all materials are ready for a perfect drop. Trap and data collection are another major responsibility of the chief scientists, and this will be the topic of the next blog.

Thanks for reading,

Walt (Mr. Charuba to my students.)

Science and Technology Log 

Above is a spreadsheet of some of the Chrysaora fuscescens data that was collected on September 15.  The first trawl was at 4:48 pm, the second at 6:39 pm and the third at 8:20 pm.  A fourth trawl was deployed at 10:49 pm. A total of 204 jellies were sorted and measured.  Of these, the first 7jellies measured from trawl numbers’ 46, 47 and 48 are recorded above. All of the species in this data set are Chrysaora fuscescens. Using the spreadsheet, create a graph that compares mass to length for these 21 animals.  When you believe you have completed this, answer the questions listed below.

Screen shot 2013-04-20 at 1.48.14 AM

Questions:

  1. Is your graph complete?
  2. Check to see if you have included; all units-mass in kilograms, length in millimeters; a legend that includes the code of the points; title for each axis(length of jelly in millimeters, mass of jelly in kilograms); title for graph.
  3. Did you make a scatter plot, bar graph or line graph? The best choice would be a scatter plot, this may give an indication of patterns in the relationship between length and mass.
  4. Can you see any pattern?  Is there a relationship between mass and length? This would be indicated by a linear pattern in the points?
  5. Do there appear to be any points that do not fit a general pattern?  What might cause these points that do not fit the norm to exist?
  6. Compare your graph with the one shown below, generated by the computer.

Screen shot 2013-04-20 at 1.48.32 AM

These Chrysaora fuscescens were caught in “jelly lane”, in the waters near Pacifica, CA that are known to have large jelly populations.  It is also an area known for leatherback sightings because of this food source. A great deal of information is known about the oceanographic conditions in this near-shore habitat. The reason the LUTH survey is crisscrossing off the continental shelf, is that much less is known about deeper offshore waters as a potential food source for migrating leatherbacks.  The routes they travel on must have some food available, so we are working to find out where that is, and gain information about relationships to oceanographic variables so that researchers will be able to eventually estimate where that food is using satellite images that will be translated into jellyfish habitat.

Personal Log 

There was quite a bit of excitement today up on the flying bridge. Although we were traveling out beyond the continental shelf, we moved over a front of water that had an abundance of moon jellies.  It was unexpected and the scientific team became very excited. New plans were made based on this observation and a decision was made to cross back across the front and collect temperature data within the water column every 10 minutes.  Quantitative observations were made of all jellies seen port and starboard and a net trawl was deployed at one point along the zone of interest.  It was quite a day. We also spotted blue sharks, ocean sunfish, and a swordfish jumping.  It was a good day.

Questions of the Day 

  1. What might be possible reasons the scientific team was excited at finding jellyfish out beyond the continental shelf?
  2. The weather has been very calm and mostly overcast.  One of the officers told me he would much rather have those conditions, than windy and sunny.  What effect might wind have on a sturdy, ocean-going ship?

Science and Technology Log 

As the scientific team conducts its research locating areas where jellyfish congregate, they have determined that samples need to be taken along both sides of a warm water/cold water boundary.  The charts below comprise a computer-generated chart of water temperature in the area we are focusing on. The chart on the right was created from remotely sensed data obtained from a satellite, and a small square of that is enlarged on the left. The chart on the left is produced from a computer model that smoothes out the lines and includes data taken continuously from the ship and integrated into the chart. Although hard to read at this resolution, the legend shows where CTD’s have been deployed, along with XBT’s, which record temperature. It also marks where upcoming deployments will take place. Net trawls were also deployed to collect samples of jellyfish that might be in the region. The quest is on for good turtle habitat.

After examining these charts above, please answer the following questions:

  1. What can you tell about the temperature of the water just off the coastline for most of that area of California?
  2. What range temperature of water does it appear that the LUTH survey is currently sampling in?
  3. Would you expect to find the same organisms in each of the samples? Why or why not?
  4. What might cause temperatures to be different in some parts of the ocean?

The Expendable Bathy Thermograph (XBT), consists of a long copper wire shot into the water down to 760 m.  When kept in the water for 2 minutes, the cable registers a signal to a dedicated computer, giving temperature readings along the wire, which are immediately plotted onto a graph.

After looking at this graph, answer the following questions:

  1. What temperature is measured at the surface?
  2. At what depth below the surface does the temperature start to drop dramatically? How many degrees Celsius is the drop?
  3. How many more degrees does the temperature drop, after the initial quick decrease? In how many meters does this gradual drop occur?

The LUTH survey is very interested in finding out whether jellyfish are found in the colder water (yellow and green), and how the distribution changes through the changing temperature of the water. Their questions surround what conditions would allow leatherbacks to travel along certain routes to and from the California coast, and how to identify areas of productivity so that commercial fishing can occur without harming protected species. Every jellyfish caught, either by the net trawls or the bongo net, and oceanographic data collected at the same time, provides more insight into where favorable conditions might exist.

It is a very different lifestyle to have a profession that involves living for periods of time aboard a ship. Most of us land-based folks get up, wander through the house, eventually rounding up food and heading off to school or work.  For me, after a day full of movement all over Chico Junior High’s large school grounds, I may go to the store, run errands and then return home to read the paper, clean house, and prepare dinner.  My family will eventually arrive home and we will go over the day’s events.  Here, the crew spends up to 23 days in this home, office and recreational area, away from their families.  Two cooks prepare, serve buffet-style and clean up after all meals; serving at 7am, 11am and 5pm.  During off hours, I have observed T.V. or movie watching, card games in action and some gym use.

Many people have iPods and in some areas music is broadcast. Personal computers with satellite internet capabilities are used, I assume, to communicate with friends and family on land.  It is interesting that the ‘living room’, which is also the mess hall, may have 10 colleagues in it sometimes watching a show. I am used to cooking when I choose, or just making cookies if I want or heading outside to jog with my dog after school. No such activities like that happen here.  Every one in the crew seems to get along, is extremely polite to each other, and is also very pleasant.  It takes a very flexible person to enjoy living on a ship and a certainly love for the ocean.  I am enjoying this very different way of living, and will also enjoy when I can run a few miles through the park again.

Bow Chamber

Bow Chamber

Science and Technology Log 

The Bow Chamber! Wow! The Bow Chamber is in the bulbous bow. It is located in the very front of boat where the V hull is. Basically this area breaks up the water pressure to create less drag. The chamber is actually a little room about 20 feet down below the main deck. It has port holes/windows so you can see aquatic life. Currently the windows have a lot of algae on them so it is hard to see out of them during the day. A group of us went down after dark and we could see bioluminescent creatures zipping by. We were seeing things such as dinoflagelletes/ plankton and jelly fish. It was so beautiful to watch.

Great day. I got up at 5:30am to watch and learn a little more about the CTD, which I wrote about yesterday. We completed our 2 final sets and I gathered goodies to bring back to school. We had the perfect ending to our last set. One of the very last hooks we pulled in possessed a huge, enormous Blue Shark. He was the biggest that we had caught so far, in length (229 cm) and girth. He gave a huge fight while in the water and even threw up a little (but thankfully not his stomach) before they got him onto the cradle. The best part of this was that the rest of the scientists could watch the people on the platform work with the shark, because the long line hauling was finished. It was truly the perfect ending to the perfect adventure.

Question of the Day 

How do bioluminescent creatures shine?
