Mission: Channel Islands Deep-Sea Coral Study
Geographical Area of Cruise: Channel Islands, California
Date: Wednesday, March 11, 2015

 

Ms. Raskin will be joining NOAA scientists on a research expedition in the waters around the Channel Islands. NOAA scientists will be using ROVs (remotely operated underwater vehicles) to look at deep­-sea coral and water chemistry and the effects of ocean acidification.

 

The water pressure in the deep sea is very strong… which makes for a fun science activity! Students in Ms. Alstot’s Environmental Science class decorated styrofoam cups which Ms. Raskin will take with her on the boat. Those cups will go down in the ROV and when they return to the surface, the extreme pressure will have shrunken the cups! Stay tuned to see how it turns out.

Science and Technology  Log 

A few hours into our shift midnight we get the word we have been expecting for several days – government shutdown. Our mission will be cut a few days short. That reality means the Bigelow has 24 hours to return to its homeport of Newport,  R.I.  It takes us 10 hours and we dock around 1 in the afternoon. With our fisheries operations suddenly declared over comes clean-up time, and we spend the next 6 hours of our shift cleaning up the on‐board fish lab. It is a time consuming but important process. The lab needs to be spotless and “fish scent” free before we can call our work finished on this cruise.  The lab is literally solid stainless steel and every surface gets washed and suds downed so there is no residue remaining.

Eau de fishes

Fish scales hiding under a flap!

Our work is inspected by a member of the crew. If it were the military, the officer would have had white gloves on I believe, just like in the old movies, rolling his finger over a remote spot looking for the dust we missed. But this is a shining stainless steel fish lab so there are two simultaneous inspections going on at once – the one with the eyes and the one with the nose.  It takes us twice to pass the visual inspection as small collections of fish scales are spotted in a few out-of‐the way areas. It takes us one more pass to clear the smell inspection. Up and down the line we walk, we can all smell the faint lingering perfume of “eau de fishes,” but we are having trouble finding it. We keep following our noses and there it is. Hiding under a black rubber flap at the end of the fish sorting line we find a small collection of fish scales revealed  when the flap is removed for inspection.  With that little section cleaned up and sprayed down the lab is declared done! There is a smile of satisfaction from the team. It is that attention to detail that explains why the lab never smelled of fish when I first boarded the ship 10 days ago nor has it smelled of fish at any time during our voyage. There is a personal pride in leaving the lab in the same shape we found  it. Super clean, all gear and samples stowed, and ready for the next crew to come on board – whenever that turns out to be.

The abrupt and unexpected end to the cruise leaves me scrambling to change my travel plans. Like the ship, I have a limited amount of time to make it home on my government travel orders. The NOAA Teacher at Sea team goes above and beyond to rebook my flights and find me a room for the night.

Personal Log 

On the serendipitous side, the change in plans gives me a little time to see Newport, a town famous for its mansions and the Tennis Hall of Fame.  My first  stop is  the Tennis  Hall  of  Fame.  My father was a first class  tennis  player who invested many  hours  attempting to

teach his  son the game. Despite the passion in  our  home  for  the  great  sport  we  never  made it  to  the  Tennis  Hall  of  Fame in  Newport.  Today I get the  chance to fulfill that  bucket  list  goal. I still remember being court side as a young boy at The  Philadelphia Indoor Championships watching the likes of Charlie Pasarell, Arthur Ashe, and Pancho Gonzales playing on the canvas tennis court that was stretched out over the basketball arena. There was even a picture of the grass court lawn of the Germantown Cricket Club from its days a USTA championship venue before the move to Forest Hill, NY. I grew up playing on those tennis courts as my father belonged to that  club. Good memories.

Clark Log 4b

There was also a  “court tennis” court, the game believed to be the precursor  to outdoor  tennis. Court  tennis derived from playing a  tennis  type  game  inside a walled‐in  court yard.  Using  the  roof and  the  wall and the open side windows to beat your opponent is all part of the game. I played court tennis as a  young teen. It’s a very unique game that is only played in a few spots now. There are only 38 court tennis courts in the world and Newport has two of them. If you like tennis, give court tennis a go if  you ever get the  chance.

The tennis court

Thoughts of a leisurely stroll evolve into a brisk walk as I head toward the ultimate and most famous Newport mansion: The Breakers, the 100,000 plus square foot summer home of the Vanderbilt family. This house has to be toured to understand the conspicuous consumption as a  pastime of the then super rich. My 2000 square foot  home would fit entirely inside  the  grand  hall  of  the  Breakers.  In  fact you could stack my home three high and they would still be below the Breaker’s ceiling. A ceiling inspired by Paris, a billiard room with walls of solid marble overlooking the ocean, a floor of thousands of mosaic floor tiles all put  down by hand one by one, a stair case from Gone With the Wind, and 20 bathrooms to choose from all speak  to the wealth and pursuit of elegance enjoyed by  the Vanderbilt clan. It is a lifestyle of a bye–gone era often referred to as the “Gilded Age.” It is  an apt description.

After sightseeing, it’s off to the bus stop for my shuttle to the Newport Airport where I take off at dawn the next morning to head for  home. I’m  leaving  so  early that the complementary coffee isn’t out yet! After an uneventful flight comes the end to an amazing adventure. Nothing left now except laundry and memories. And lots of great ideas for lesson plans to work into my classes. Thank you NOAA Teacher at Sea Program for offering me the learning experience of a lifetime. I cannot wait to get back and share the experiences with my students.

It’s going to be a busy night trawling and processing our catch.  Yippee. I like  being busy as the time passes more quickly and I learn about more fish. A large number of trawling areas are all clustered together for our shift. For the most part that means the time needed to collect data on one trawl is close to the amount of time needed for the ship to reach the next trawling area. The first trawl was a highlight for me as we collected, for the first time,  a few puffer fish and one managed to stay inflated so I had a picture taken with that one.

We found a puffer

We found a puffer

However, on this night there was more than just puffer fish to be photographed with. On this night we caught the big one that didn’t get away. One trawl brings in an amazing catch of 6 very large striped bass and among them is a new record: The largest striped bass ever hauled in by NOAA Fisheries! The crew let me hold it up. It was very heavy and  I kept hoping it would not start flopping around. I could just see myself letting go and watching it slip off the deck and back into the sea. Fortunately, our newly caught prize reacted passively to my photo op. I felt very lucky that the big fish was processed at the station I was working at. When Jakub put the big fish on the scale it was like a game show – special sounds were emitted from our speakers and out came the printed label confirming our prize  – “FREEZ – biggest fish ever “-‐-‐the largest Morone Saxatilis (striped bass) ever caught by a NOAA Fisheries research ship.  It was four feet long. I kept  waiting for the balloons to come down from the ceiling.

Catch of the day

Every member of the science team sorts fish but at the  data  collection tables my role  in the  fish lab is one of “recorder”. I’m teamed  with  another scientist who serves  as  the “cutter”, in this  case Jakub. That person collects the information I enter into the computer. The amount of data collected  depends on  the quantity and  type of fish  caught in  the net. I help  record  data on length, weight, sex, sexual development, diet, and scales. Sometimes fish specimens or parts of a fish, like the backbone of a goose fish, are preserved. On other occasions, fish, often the small ones are frozen for further study. Not every scientist can make it on to the Bigelow to be directly part of the trip so species data and samples are collected in accordance with their requests.

Collecting data from a fish as large as our striped bass is not easy. It is as big as the processing sink at our data collection  station and it takes Jakub’s skill with a hacksaw-‐-‐yes I said hacksaw-‐-‐to open up the back of the head  of the striped  bass and retrieve  the  otolith, the  two small bones  found behind the head that are  studied to determine  age. When we  were  done, the fish was bagged and placed in the deep freeze for  further  study upon our return. On the good side we only froze one of the six striped bass that we caught so we got to enjoy some great seafood for dinner. The team filleted over 18 pounds of striped bass for the chef to cook up.

Too big for the basket

More Going On: 

Processing the  trawl is not the  only data  collection activity taking place on the  Bigelow.  Before most trawls begin the command comes down to “deploy the bongos”. They are actually a pair  of  closed end nets similar to nets used to catch butterflies only much longer. The name bongo comes from the deployment apparatus that holds the pair of nets. The top resembles a set of bongo drums with one net attached to each one. Their purpose, once deployed, is to collect plankton samples for further study. Many fish live off plankton until they are themselves eaten by a predator farther up the food chain so the health of plankton is critical to the success of  the ecological food chain in the oceans.

Processing

Before some other trawls, comes the command to deploy the CTD device. When submerged to a target  depth  and  running in  the water as the ship  steams forward, this long fire extinguisher sized  device measures conductivity and temperature at specified depths of the ocean. It is another tool for measuring the health of the ocean and how current water conditions can impact the health  of the marine life and also the food chain in the area.

Personal Log 

On a personal note, I filleted a fish for the first time today – a  flounder. Tanya, one  of the science crew taught me how to do it. I was so excited about the outcome that I did another one!

Science and Technology  Log 

I was  told  that  the  first  12  hour night watch shift was the hardest for staving off sleep and those who spoke were right. Tonight’s  overnight shift seems to be flying by and I’m certainly awake. Lots of trawling and sorting this  evening with four sorts complete by 6am. One was just full of dogfish, the shark looking fish,  and  they  process  quickly  because  other  than  weight  and  length there is little request for other data. The dogfish were sorted at the bucket end of the job so determining sex had already been completed by the time the fish get to my workstation. Again I’m under the mentorship of Jakub who can process fish faster than I can print and place labels on the storage envelopes. The placement of the labels is my weakness as I have no fingernails and removing the paper backing from the sticky label is awkward and time consuming. Still tonight I’m showing speed improvement over last night. Well at least I’m getting the labels on straight most of the time.

Sorting fish

Sorting fish

In  addition  to  the  dogfish,  we  have  processed  large  quantities  of  skate  (the  one  that  looks  like a  sting  ray to me), left  eyed flounders, croakers (no relation to the frog), and sea robins of which there are two types, northern and stripe. The sea robins are  very colorful with the  array of spines just behind the  mouth. And yes it hurts when one of the spines goes through your glove. Sadly for me sorting has been less exciting tonight.  With  the big fish being grabbed off at the front of the line there has been little left for me to sort. I feel like the goal keeper in soccer  – just  don’t let them get past me. To my great surprise, so far I’ve experienced no real fear of touching the fish. The gloves are very nice to work with.

Species in specific buckets

Species in specific buckets

And let us not overlook the squid. There have been pulled in by the hundreds in the runs today. There are two types of squids, long fin (the lolligo) and short fin (the illex). What they both have in common is the ability to make an incredible mess. They are slimy on the outside and  inky on the inside. They remind me of a fishy candy bar with really big eyes. And  for all the fish  that enjoy their squid  treat the species  is,  of  course,  (wait  for  it) just  eye  candy.  The  stories  about  the  inking  are  really  true. When  upset, they give  off ink; lots of ink. And  they are very upset by the time they reach the data collection stations. If you could bottle their ink you would  never need  to  refill your pen  again. They are also  very, very  plentiful which  might explain  why there are no requests to collect additional data beyond  how long they are. I guess they are not eye candy to marine scientists. However, there vastness is also their virtue. As a food source for many larger species of marine life, an absence of large quantities of squid in our trawling nets would be a bad sign for the marine ecosystem below us.

When the squid are missing, our friend the Skate (which of  the four  types does not  matter)  is glad to pick up  the slack on  the “messy to work with” front. As this species makes it down the sorting and data collecting line the internal panic button goes  off and they exude this thick, slimy substance  that covers their bodies and makes them very slippery customers at  the weigh stations.  It turns out the small spines on the tails were placed there so that fisheries researchers could have a fighting chance to handle them without dropping. Still, a skate sliding onto the floor is a frequent event and provides comic relief for all working at the data collection stations.

Clark Log 2There was new species in the  nets tonight, the  Coronet fish which looks like  along  drink straw with stripes  and a string attached to the back end. It is  pencil thick and about a foot long without the string. We only caught it twice during the trip. The rest of the hauls replicate past  sorting as dogfish, robins, skates, squid, croakers, and flounder are the bulk of the catch. I’ve been told that the diversity and size of the trawl should  be more abundant as we steam along the coastline heading north  from the lower coast of  New Jersey. Our last trawl of the shift, the nets deployed collect two species new for our voyage, but ones I actually recognized despite my limited knowledge of fish – the Horseshoe Crab and a lobster! I grew up seeing those on the Jersey shore.  We only got one lobster and after measuring  it we let  go  back  to  grow  some  more.  It  only  weighed in at less than two pounds.

Personal Log 

The foul weather suit we wear to work the line does not leave the staging room where they are stored as wearing them around the ship is not  allowed. After  watching others, I have mastered the art  of  pushing the wader pants over the rubber boots and  thus leaving them set-‐up  for quick donning and  removal of  gear  throughout  the shift.

While the work is very interesting on board, the highlight of each  day is meal time. Even though I work the night  shift (which ends at  noon) I take a nap right after my shift so I can  be  up  and  alert in  time  for dinner. My favorite has been  the T-‐bone steaks with Monterey seasoning and  any of the fish cooked up from our trawling like scallops or flounder. The chef, Dennis, and his assistant, Jeremy serve up some really fine cuisine. Not fancy but very tasty. There is a new soup every day at  lunch and so far my favorite has been the cream of tomato. I went back for seconds! Of course, breakfast is the meal all of us on the night watch  look forward  to  as there is no  meal service between midnight and  7am. After 7 hours of just snacking and  coffee, we are ready for  some solid food by the time breakfast  is served.

Seas continue to be  very calm and the  weather sunny and pleasant. That’s quite a surprise for the North Atlantic in the fall. And  the sunrise today was amazing. The Executive Officer, Chad Cary, shared that the weather we are experiencing should continue for at least four more days. I am  grateful  for  the  calm weather – less  chance  to  experience  sea  sickness.  That is something I’m determined to avoid if possible.

Science and Technology  Log 

Today is my first full 12 hour shift day. I’m on the night crew working midnight to noon. Since we left port yesterday I’ve been  trying to  adjust my internal clock for pulling daily “all night”ers.  On Monday, after we  left port, safety briefs for all hands occurred once we made it out to sea and I got to complete my initiation into the Teacher at Sea alumni program  – the donning of  the Gumby suit as I call it. It is actually a bright red wet suit that covers your entire body and makes you look like a TV Claymation figure from the old TV show. In actuality it is designed to help you survive if  you need to abandon ship. Pictures are  of course taken to preserve this rite of passage.

The Henry B. Bigelow is a specially-built NOAA vessel designed to conduct fisheries research at sea.  Its purpose is to collect data that will help scientists assess the health of the Northern Coastal Atlantic Ocean and the fish populations that inhabit it. The work is invaluable to the commercial fishing industry.

Yesterday, I learned how we will go about collecting fisheries data. Our Chief Scientist, Dr. Peter Chase, has selected  locations for sampling the local fish population and the ship officers have developed a sailing plan that will enable the ship to visit all those locations, weather permitting, during the course of the voyage. To me its sounds like a well-‐planned  game of connecting the dots. At each target location, a trawling net  will be deployed and dragged near the bottom of the sea for a 20 minute period at a speed of 3 knots. Hence the reason  this voyage is identified as a bottom trawl survey mission. To drag the bottom without damaging the nets is not easy and there are five spare nets on board in case something goes wrong. To minimize the chance of damaging the net during a tow, the survey technicians use the wide beam sonar equipment to survey the bottom prior to deployment. Their goal is to identify a smooth path for the net to follow. The fish collected in the net are sorted and studied, based on selected criteria, once on board. A  specially designed transport system moves the fish from the net to the sorting and data collection stations inside the wet lab. I’m very excited to see how it actually works during my upcoming shift.

The big net.

Work is already underway when our night crew checks in. The ship runs 24/7  and the nets have been down  and trawling since 7pm. Fish sorting and data collection  are  already underway.  I don my foul  weather gear which  looks  like a set of waders used for British fly fishing.  There is also a top jacket  but the weather is pleasant  tonight and the layer is not needed. I just need to sport some gloves and get to work. I’m involved with processing  two trawls of fish right away. I’m assigned to work with an experienced member of the science team, Jakub. We will be collecting information on the species of fish caught on each trawl.  Jakub carries out the role as cutter, collecting the physical  information or fish parts needed by the scientists. My role is recorder and  I enter data about the particular fish  being evaluated  as well package up  and  store the parts of the fish  being retained  for future study.

Data collection on each fish harvest is a very detailed. Fish are sorted by species as they come down the moving sorting line where they arrive after coming up the conveyer belt system from the “dump”  tank, so  named  because that is where the full nets deposit their  bounty. Everybody on the line sorts fish. Big fish get  pulled off  first  by the experienced scientists at  the start  of  belt  and then volunteers such as I pull off the smaller fish. Each  fish  is placed  into  a bucket by type of fish. There are three types of buckets and each bucket has a  bar code  tag. The  big laundry  looking  baskets  hold  the  big  fish,  five  gallon  paint buckets hold  the smaller fish, and  one gallon  buckets (placed  above the sorting line) hold  the unexpected  or small species. On  each  run  there is generally one fish  that is not sorted  and  goes all the way to the end untouched and unceremoniously ends up in the catch-‐all container at the  end of the  line. The watch leader weighs the buckets and then links the bar code on the bucket to the type of fish in it. From there  the  buckets are  ready for data  collection.

Clark Log 1d

The sorting line

After sorting the fish, individual data collection begins “by the bucket” where simultaneously at three different stations the sizing, weighing, and computer requested activities  occur. By  random sample certain work  is  performed on that fish. It  gets weighed and usually opened up to retrieve something from inside the fish. Today, I’ve observed several types of  data collection. Frequently requested are removal of  the otolith, two small bones in the head that  are used to help determine the age of  the fish. For bigger fish with vertebra,  such  as  the  goose  fish,  there  are periodic  requests  to  remove a  part  of  the backbone and  ship  it off for testing. Determining sex is recorded  for many computer tagged  fish  and  several are checked stomach contents.

Of the tools used to record data from the fish, the magic magnetized measuring system is the neatest. It’s  rapid  fire  data  collecting  at  its  finest.  The  fish  goes  flat  on  the measuring  board;  head  at  the  zero point, and  then a quick touch  with  a magnetized block at the end  of the fish  records the length  and  weight. Sadly, it marks the end of tall tales about the big  one that got  away and keeps getting bigger as the story is retold. The length of  the specimen is accurately recorded for  posterity in an instant.

I arrive a day prior  to sailing so I have half a day to see the sites of Newport, Rhode Island  and  I know exactly where  I’m headed – the Tennis Hall of  Fame.
