Sphere Cameras:

As we travel along the coastal shelf of Texas to Louisiana, scientists have already mapped out drop sites for the Sphere Cameras. There are five cameras that have a 360 degree view, one camera is stereo paired for measurements, and one is facing straight up. The cameras are attached to a rosette (cage), as well as bait to attract fish. Once the cameras are dropped in their designated location they will record for approximately 30 minutes. It is a process dropping the cameras in and picking them up that both the scientists and deck crew all have to help out with. It is hard to believe that by the end of their mission (Legs 1-4) they will have done this over and over around 500 times. Once all footage is collected from the day and downloaded it is then stitched together. This information allows scientist to see a number of things including biodiversity, distributions, and habitat classifications. This is helpful because it is also a much less invasive way for scientists to collect data.

Two members of the science crew, wearing hard hats and life vests, stand on deck, facing a large metal cage hoisted up on ropes. The cage houses underwater cameras. The crewmembers are steadying the apparatus with additional ropes as a davit arm lifts it over the railing of the deck.

Tony is responsible for anything electronic. This could include things like wind, temperature and pressure sensors, electronic connections for the scientific computer systems, and GPS position for mapping. He states, “Anything that can be recorded for future data collection accuracy is very important.” Tony is also in charge of letting others know if the ship needs help. Tony has been on several ships in his lifetime including spending twenty years in the Navy. When Tony retires he hopes to work at a train museum in New York, due to his fascination with trains. He has been a great person to talk to while on this journey and is always willing to give me any information I ask. He even took time out to give me a tour of the bridge and flying bridge, as well as giving me several lesson ideas of coding for my students.

Chris Rowley, Lead Fisherman

Chris is the lead fisherman on Pisces. His job is to assist the scientists in deploying cameras and CDT, and anything else needed. NOAA provides great benefits to support his family. Chris also is a coxswain who drives the Fast Rescue Boat (FRB) if needed. He is also part of the fire drill and you can see him in the pictures below during the drill. Chris lives in Louisiana and enjoys spending any off time he has with his twin daughters and wife.

Student Questions of the Day for Tony and Chris

Alivia and Tucker ask: How many different ships have you been on?

Tony was a great one to answer this question. Tony was on two naval ships, and eight different NOAA ships. I would say he has had a lot of experience in maritime.

Aryan and Alivia ask: When did you start working for NOAA?

In 2004 Tony started working for NOAA.

Maverick asks: What do you do in your free time?

Tony enjoys woodworking, religious teaching, and is involved with a food bank rescue ministry when he isn’t out to sea.

Konnor asked: What did you do before this job?

Chris started in High School working in the summers on shrimp boats as a deckhand in Louisiana. Before working for NOAA, he worked several years on offshore supply vessels (OSV).

Holden, Karson, Gary, Macie, Zane, Haylee, and Liam ask: What is the coolest and largest thing you have seen in the ocean?

Chris states that at night, while working on the supply vessels, lights would shine in the dark water and he saw an albino barracuda. The largest marine life he has seen has been a whale shark and he has seen several orcas.

Meela and Parker ask: Do you get lonely and do you get personal time?

Chris works out on the ocean over nine plus months out of the year. He looks forward to vacation where he can spend more time with his family back home. The ship now has internet that helps keep them in touch with family.

Personal Log

Last night we had to start working our way inland about 20 miles offshore, due to a large storm out in the Gulf. Tomorrow we plan to head back out towards our mission locations to continue where we left off. We have been tracking the storm for a few days and knew that we would need to go somewhere due to the heavy winds and waves. Since we can’t deploy cameras at our designated locations, everyone is using this day as a catch up day. We also did fire drills and abandon ship drills today. Safety is a huge priority on the ship, and I am confident that if there were to ever be an emergency situation, that everyone on Pisces would handle it excellently. I am taking advantage and downloading photos and working on the blog today, and checking in with my students work back home. Yesterday was amazing! I love getting my hands dirty and take every chance I can get to help cut bait for the baited cameras. I got to see my first whale at sea, and I have had the opportunity to see dolphins a few times now. I find myself often looking for marine life. There are always amazing sunsets at the ocean.

Crew of the NOAA Ship Oregon II

It is no small feat to conduct a research survey for NOAA. It takes many individuals with many different strengths to ensure a safe and successful cruise. From the captain of the ship who is responsible for the safety of the ship and the crew, to the stewards who ensure the crew is well fed and well kept, every crew member is important.

I interviewed many of the crew members to get a better idea of what their jobs entail and what they had to do to become qualified for their jobs. I complied all of the interviews into a video to introduce you to some of the Oregon II’s crew.

Safety Aboard the Oregon II

While out at sea, safety is a critical issue. Just as schools have fire and tornado drills, ships have drills of their own. All crew members have a role to fulfill during each drill. Emergency billets (assigned jobs during emergencies) are posted for each cruise in multiple locations on the ship.

Fire on a ship is a very critical situation. Because of this, fire drills are performed frequently to ensure all crew recognize the alarm, listen to important directions from the captain, and muster to their assigned stations. (To muster means to report and assemble together.) One long blast of the ship’s whistle signals a fire. (Think of someone yelling “Firrreee!!!”) Each crew member is assigned to a location to perform a specific duty. When the fire whistle is blown, some crew members are in charge of donning fire fighting suits and equipment, while others are in charge of making sure all crew have mustered to their stations.

Another drill performed on the ship is the abandon ship drill. This drill is performed so that crew will be prepared in the unlikely event that the they need to evacuate the ship. Seven short blasts of the ship’s whistle followed by one long blast signals to the crew to abandon ship. Crew members must report to their staterooms to gather their PFDs (personal flotation devices), their immersion suits, hats, long-sleeved shirts, and pants. Once all emergency equipment is gathered, all crew meets on the deck at the bow of the ship to don their shirts, pants, hats, immersion suits, and PFDs. All of this gear is important for survival in the open ocean because it will keep you warm, protected, and afloat until rescue is achieved.

The last drill we perform is the man overboard drill. This drill is performed so that all crew will be ready to respond if a crew member falls overboard. If a crew member falls overboard, the ship’s whistle is blown three times (think of someone shouting “Maann Overr-boarrrd..!). If the crew member is close enough, and is not badly injured, a swimmer line can be thrown out. If the crew member is too far away from the ship or is injured, the RHIB (Rigid Hull Inflatable Boat) will be deployed and will drive out to rescue the crew member. The crew member can be secured to a rescue basket and lifted back onboard the ship.

It is important to practice allof these drills so that everyone can move quickly and efficiently to handle and resolve the problem. All drills are performed at least once during each cruise.

Daily safety aboard the Oregon II is also important. When any heavy machinery is in operation, such as large cranes, it is important that all crew in the area don safety equipment. This equipment includes a hard hat and a PFD (personal flotation device). Since cranes are operated at least once at every sampling station, this safety equipment is readily available for crew members to use

I have now returned home from my grand adventure aboard the Oregon II. It took a few days for me to recover from “stillness illness” and get my land-legs back, but it feels nice to be back home. I miss working alongside the crew of the Oregon II and made many new friends that I hope to keep in touch with. Being a Teacher at Sea has been an experience of a lifetime. I learned so much about life at sea and studies in marine science. About half way through the cruise I had started to believe this was my full-time job! I am eager to share this experience with students and staff alike. I hope to spark new passions in students and excitement in staff to explore this opportunity from NOAA.

I want to thank all of the crew of the Oregon II for being so welcoming and including me as another crew member aboard the ship. I also want to thank the NOAA Teacher at Sea Program for offering me such a wonderful opportunity. I hope to be part of future opportunities offered by this program.

Science and Technology Log
In a recent post, I talked about how one of the things we are doing on board the Oscar Dyson is trawling for fish. The video from that post showed what happens in the fish lab during a midwater trawl. Remember that there are two nets we have been using for a midwater trawl: first, the normal Aleutian Wing Trawl, or AWT, which catches plenty of pollock, but also the 83-112 to which adjustments are being made to use this bottom trawl net for midwater fishing. But what about using the 83-112 for its original purpose: bottom (or benthic) trawling?

Bottom Trawl

I’ve been lucky enough to see two bottom trawls on this cruise, although neither of them were actually during my shift. My wonderful roommate Carwyn, one of the other scientists on board, came to tell me about the bottom trawls so I could see all the neat creatures from below! A bottom trawl is used when the pollock are swimming much lower in the water column for one reason or another, but in trying to catch them, there are always many more “trawling treasures” that find their way onto the fish table. The process is basically the same as a midwater trawl, except the 83-112 net is lower down in the water towards the bottom of the sea floor (hence the term bottom trawl). The net is also much shorter in length than the AWT using in midwater trawling.

DYK?: How do the scientists know exactly how far down the net is in the water column? One of the sensors attached to the net is called the SBE (Seabird) 39. This will measure the depth and temperature during the trawl and determine the average head rope depth (which is the top of the net) and average temperature during the trawl between EQ (equilibrium – start of the trawl) and HB (haul back – end of the trawl). The sensor is then uploaded on the computer and the data is used by the scientific party.

Headrope Haul 76 — This plot is used to determine the average head rope depth and temperature during the trawl (between EQ and HB). Depth is measured in meters and temperature in degrees Celsius on the y-axis versus time on the x-axis.

Field Guides — Field guides to classify various species found in the Pacific Ocean.

I attempted to classify all of these great bottom trawl treasures, and discovered that this was way easier said than done. There are some books in the fish lab with photos and descriptions just of the species that may be found around the Alaskan waters, and it was incredibly difficult to nail down a specific species for most of the finds!

In the bottom trawl, we found things such as the Oregon hairy triton, an unidentified pretty purple star fish, pink shrimp, basket stars, sheriff’s star, halibut, crabs, pacific cod, sculpin, Pribilof snail, sea anemone, scallop, sponge, sea pens, arrowtooth flounder, flathead sole, chiton, and seaweed.

Bering Sea Bottom Trawl Treasures

Methot Trawl

The other trawl we’ve done outside of the normal AWT (Aleutian Wing Trawl) midwater and 83-112 midwater comparison trawl is something called a methot trawl. This uses a completely different net because the others have mesh that is much too large to catch something so small. The methot net has very fine mesh and a hard square opening with a fixed height. The cod end (very end of the net) is actually a small white container because the organisms collected are so small. A methot trawl is done to collect euphausiids, otherwise known as krill. Sometimes other microscopic (small) organisms are collected as well, including jellies, salps, and amphipods, which must then be carefully sorted out.

DYK?: Krill are part of the phylum Arthropoda, which includes species with an exoskeleton and jointed legs such as spiders, crabs, insects, and lobsters. They are an important part of the ecosystem because these small, reddish-orange animals are a source of food for many larger animals.

Steps to process a methot trawl in the fish lab:
1. Dump contents of the hard cod end container into a large gray bin.
2. Remove any large jellyfish (and weigh those separately).
3. Rinse contents from the gray bin into the sieve to remove any water.
4. Using tweezers, sort through the small microscopic organisms on the sieve and remove anything that isn’t krill.
5. Weigh krill sample.
6. Collect a random subsample in a scoop and weigh it.
7. Count all of the krill in the subsample (yes, this is as tedious as it sounds!).

Bowthruster — Heading down to check out the bowthruster on the *Oscar Dyson*!

It continues to be a little slow on the trawling during my shift, but that’s okay, because I was lucky enough yesterday to get a tour of some of the lower bridge levels from the 1^st Assistant Engineer, Tony.

DYK?: There are 8 levels on the Oscar Dyson. They are numbered, starting from the topmost deck, as follows:
O4 – flying bridge
O3 – bridge
O2 – staterooms (CO, XO, chief scientist)
O1 – staterooms (scientists), CTD winch, FRB (fast rescue boat), Peggy D (boat), liferafts
1 – galley, labs (acoustics, chem, dry, fish)
2 – engineering (machinery, centerboard, oceanic winch, trawl winch, and more), staterooms (deck crew and then some)
3 – engineering (machinery, bilge/ballast, workshop, and more)
4 – bowthruster, transducer, fuel oil tanks, ballasting tanks

I plan to share some of the facts I learned related to chemistry and biology from this tour (and other things on board) in one of my next blogs, so be sure to look for all of the info on the generators, sea water purification, MSD, cathodic protection system, and more.

We did have two trawls yesterday (July 10) – the first was an AWT midwater trawl that had caught so many fish it was actually a “splitter”! In a splitter, there’s an extra step between hauling in the net and getting it to the table in the fish lab. The cod end of the AWT net is opened over a separate splitting crate, where there is another net underneath that will only take about half of the fish to release on the table. The rest are then returned to the water.

Splitting an AWT midwater trawl that collected too many pollock.

We also had drills yesterday (these are required once a week) and after gaining permission from the bridge, I checked in to my muster station (which is in the conference room for the science party, away from all of the action) and then went and watched what everyone else on board does. When we have fire drills in school, the alarm sounds, we walk outside, and wait for the “all clear” before heading back in. When they have fire drills on the Oscar Dyson, they use a smoke machine to produce smoke, there is an on-scene crew (first responders), there may or may not be a “victim” involved, the hose team actually dresses out (with the help of another person on the alpha or bravo firefighting teams), and the fire hoses are actually used. It may seem like old hat to everyone else on board, but I found it incredibly interesting to watch!

Following the fire drill, there was an abandon ship drill, where everyone on board grabs their survival suit, PFD, and heads to one of three life rafts (there are actually 6 on the ship). The CO had me stay up in the TV lounge so that my life raft (#5) wouldn’t have a “full muster” until they sent out a search party to find me. Just as there are two people on hose team in both alpha and bravo for the fire drill, people must go in pairs for the search party, so Patrick and Rick came and found me. I think some people thought I’d actually not heard the alarm (I was wearing headphones), but I was instructed to be up there! We will have one more day of drills before we get back to Dutch Harbor, so maybe I’ll actually don my bright orange survival suit, which other Teachers at Sea in the past have affectionately called the “gumby suit” (even though Gumby was green).

Animal Love
In yesterday’s AWT midwater trawl, we had a new visitor in the fish lab. Introducing the lumpsucker!

The lumpsucker is in the family Cyclopteridae, which is derived from Greek words that mean circle and fin in reference to their round-shaped pectoral fins. There is a sucker on the bottom of them, so when we put this little sucker in some sea water while we were processing the fish, he stuck himself to the bottom of the container! Lumpsuckers are poor swimmers, so they are mostly benthic, meaning they stay at the bottom of the sea floor. However, that doesn’t mean they are incapable of swimming (especially since this one was caught during a midwater trawl). We took some photos and tossed this little guy back to sea, so hopefully he makes it!
