Week Fourteen: Cruising to Kodiak

Greetings from the damp and green shores of Kodiak, Alaska! We arrived yesterday midday and are tied up pretty close to downtown, which makes exploring a breeze. There are a lot of outdoor shops and the whole area seems like an ideal jumping-off platform for anything from surfing to hunting to backpacking up impressive craggy cliffs.

Overall, the transit up from Seattle was a pretty good one and it really gave me a chance to get a better idea as to where various labs, staging bays, and equipment are located around the ship and what the startup and shut down procedures are for each cruise. Our first day out we got to wake up all the underway systems and echosounders that the STARC technicians are responsible for maintaining.

Getting the science seawater system (SSW) going involves calling down to the engine control room so the engineers can get the positive displacement pumps on line and up to the required speed using a VFD to convert percent load requested to pump speed. There are 4 pumps in the line and they can run multiple pumps in parallel. There is also a centrifugal chamber that the water can be pumped through which can remove chunks of ice that may have been sucked in through the seachest. This is quite handy as we are headed into ice territory, after all!
 

Once the SSW was up and running, we let the water drain out into the sink at each station until it started smelling less fishy. We then adjusted flow to various instruments via a series of manifolds until our flow meter was in range (2-3LPM). Unfortunately, it was quite a struggle to maintain this flow so we started isolating parts of the system and found a blockage in the form of a mini seafood buffet in the barbed fittings entering the equilibrator tank. Once all the critters were removed, we reassembled the fittings and the flow was good to go.

Another important aspect of being on the Healy is, of course, the USCG crew members and subsequent operations (like the pyro testing below), routines, and rules. The senior officers, including the Captain and XO, are incredibly personable and I was able to sit in on several evening planning meetings with them during the transit. They have also visited the Computer Lab to say hello and ask how things are going, which is definitely above and beyond the interaction I expected.

During the transit, we launched an XBT and I was on the radio as “Aft Con” communicating with the enlisted MST officers who run all deck deployments. I quite enjoyed it and am looking forward to navigating all of the rather dense and complicated 24-hour science operations we have coming up (CTD casts, net tows, benthic grabs, sonobuoy and mooring deployments).

We will be leaving Kodiak tomorrow morning and heading up to Nome to pick up the science party and any additional equipment that has not already been loaded. On the way up, the Healy is providing support to NOAA while they board fishing vessels in the area and is also conducting flight operations training with ARISTA Kodiak. Lastly, we will be crossing in to the Domain of the Polar Bear and there may be some voluntary ceremonial participation involved.

0 Pre-Internship Post: R/V Atlantis

Hello everyone! My name is Nick Ellis, and I’m a rising sophomore at Santa Clara University studying mechanical engineering. In high school, I joined Jesuit Robotics and competed in the MATE International ROV Competition where I developed a special interest in underwater robotics. In the next couple of weeks I will begin my internship working aboard the R/V Atlantis with the HOV Alvin group. I am ecstatic at having this opportunity to experience firsthand what it’s like to work as a marine technician, and I cannot wait to begin work with these two historical research vessels. Throughout the internship, I’ll be posting about what I’ve learned and my new experiences at sea. Anchors aweigh!

Week Thirteen: 47deg N at 85deg F

2130 Local time

Well, hello!

I had a fantastic time with friends and family the past week and am now writing to you at the end of a surprisingly warm and sunny Seattle day. Earlier this afternoon I arrived at the U.S. Coast Guard base to get settled in on the Healy. As I drove past the container ship docks, two very large and red-hulled ships came into view. We slowed down to take a closer look but thought both were much too big to possibly be the Healy. Well, it turns out we were wrong. The USCG Healy is the country’s largest icebreaker and at 420′ LOA it is also the largest Coast Guard vessel.
 

After a very nice escort from base security, I made the gangway climb and was met by Brett, the Scripps STARC (Science Technical Support in the Arctic) coordinator. We spent the rest of the afternoon getting me familiarized with the ship and various science spaces and instrumentation on board. The loading bays, fantail, and science storage spaces are quite full as it is easier to load for each cruise in advance while the ship is in Seattle than it is to try to get equipment shipped up to Alaska. 

I will be working on cruise HLY1801, which will be operating in the Chukchi Sea with multiple moorings, CTD water sampling, net tows, and benthic grabs. This cruise is part of a long-term study called DBO-NCIS (Distributed Biological Observatory-Northern Chukchi Integrated Study). Their goal is to document changes to the Pacific-Arctic ecosystem due to climate change as sea ice melts back earlier and freezes later each year.

On my tour with Brett, I saw some very familiar equipment including a Bongo net (last seen during CalCOFI) and two Van Veen grabbers (last seen during GeoPaths). I also came across some new items including a Haps corer, which is evidently quite good for coarser sediments like sand. There were also an impressive number of moorings staged on the fantail and in the large staging bay area. Overall, I am very excited for this new and unique experience to begin. We will get underway some time tomorrow afternoon and will have some projects to take care of along the transit before the scientists board in Kodiak. 

More soon!

Challenging Myself

Things have been going great aboard the R/V Atlantic Explorer. We left for sea this morning, and we will be out here until Monday. I have met so many great people while I have been here.

This past week I was given the task to change out the LCI-90i winch display (see attached picture). I was a little nervous at first, but I was able to learn a lot from it. The Marine Techs have shared a lot of their knowledge with me, and I greatly appreciate it. 

I hope to work with people as great as the AE crew in the future. 

 

Week 2-aka Last Week at BIOS

Unfortunately, this is my last week at BIOS, but what a week it has been! I have to say, the time I have spent here in Bermuda has not been wasted. Plus, I think I got the best of both worlds during my stay in Bermuda. My first week started right off the bat by meeting everyone and then shipping out to sea for five days. Week two, we stayed at the port, and I got to see how the marine techs handle their “8am-5pm” lifestyle at home.

To finish off week one, we got back to port on Friday and helped unload the scientist’s gear/equipment for the first four hours. After 12 pm, the fun began. Everyone needed to decompress from a stressful cruise. Networks went down, Gyro-compass streaming was faulty, a MOCNESS deployment failure that led to re-terminating within an hour to re-deploy successfully and a seawater pump, to all the labs, explosion: to name a few things that transpired on the cruise. But, on the lighter side, I got to deploy and recover the CTD, help deploy pumps to various depths and I also got to help deploy a MOCNESS!! The CTD and pumps are generally common among most cruises but the MOCNESS is a more of a rarer deployment, so I am incredibly fortunate to have taken part in that.

So a lot happened on that cruise, which means we (the Marine Techs) had a lot of work to do before the next scheduled cruise in seven days. Our first objective was to re-terminate the CTD. By the way, if anyone was wondering what “re-terminating” means it’s essentially cutting out a section of wire, connecting “fresh” wire to the plug end of the wire and then protecting it by making it water/pressure proof. By re-terminating cables, you ensure corrosion near the plug doesn’t affect the performance of data streaming from the instrument to the computer on the ship—where Marine Techs and scientists analyze/record the data. And to give everyone an understanding of the amount of time it takes to properly re-terminate a wire, it took us roughly six and half hours to place the molding that would protect the new connection. Granted the Marine Tech was doing the re-termination was explaining and showing every step carefully so that I could understand the whole process, but generally, it’s no quick task.

Once we completed the re-termination for the CTD, we started on re-terminating our COM7 winch (another type of cable used to connect to different types of instruments). We had to stop half-way because BIOS took us on a field trip! We got to visit an island named Nonsuch where we snorkeled and visited a terrestrial protected island where ornithologists use this area to help bring back an almost extinct species of bird named Cahow.

Overall, a week at port leads to projects that focus on fixing systems that failed or gave issues during the most recent cruise. Once those projects are handled, there are always more things to do—you can count on it. When I believed we were in a good place, we had five more things to work on. But, it’s needed, and everyone encouraged each other to stay focused and accomplish the goal(s) at hand.

I would say the first week of my internship taught/developed my deck handling and problem-solving skills while the second week improved my research and wire handling skills. I am truly honored to have received this internship because it showed me a world I never knew existed. Plus, I got to meet some incredible people and have some amazing experiences while improving myself as a worker. The life of a Marine Technician is not an easy one, but it’s a great developing position that could project you into something else. Or, it could be your career, everyone is different.

The people I met at BIOS showed me how to have fun while being efficient when I work. Especially, when you think the world is ending, we support each other enough to at least smile and somehow get the job done. I hope our paths cross again BIOS; you have instilled more than just skill improvement in me, you sparked passion for pursuing work in Marine Science—something I thought I lost. Thank you for everything.

Take care.

Week Twelve: Troubleshooting

1500 local time

Hi there!

This is week 12 of my internship, which is quite extraordinary. In reflection, I am pleased as punch by how much I have learned and experienced, especially when comparing where I am now with the skills and abilities I had coming into this back in April. Being out at sea and learning “on the job” like this is akin to trying to learn a new language. You can take classes or download a software program, but if you really want to learn then you should live and fully engage yourself in the culture and region where that language is spoken.

Part of the learning process comes with being humbled by how much you still don’t know. This particular flavor of humble pie has occurred almost on a daily basis for this current cruise, which is a really cool, 2-year study of zooplankton and larval fish along Trinidad Head, California and Newport, Oregon including the ever abundant and truly bizarre pyrosomes.

Through no one’s fault, we have entered into the ultimate Murphy’s Law of science cruises. Everything from a simple dipped net to the giant and complicated MOCNESS have had various problems that have required intensive troubleshooting. Thankfully, the Chief Scientist and entire science team are real troopers and we have been able to work together and come up with solutions along the way.

The two biggest issues we ran into at the very beginning of the cruise was the deck winch stand that tows the ISIIS plankton imager stopped responding and then, so did the MOCNESS. The data provided by these two instruments is the heart of this operation and so losing both of them was going to potentially be the end of the cruise. Thankfully, we were close enough to shore that the Chief Scientist was able to call the technician and communicate the error codes so we could get it back up and running. The scientists still end up losing communication with some regularity during a tow, but at least we can now recover and re-launch without issue.

The MOCNESS has proved more of a challenge. Not only is it a beast to get in and out of the water, but the 0.680 electro-mechanical cable that allows us to talk to the unit cut in and out for the first two days. Getting it permanently back on line was quite an experience. We carefully inspected and isolated each sensor connection. We made sure the calibration profile for each sensor was correctly entered in the software program the scientists were using. We found some water damage and re-spliced cables and also used new cables. We re-terminated the connection at the instrument 4 separate times. We traced the entire circuit through the ship and ran continuity tests and insulation tests at various points junctions and noted when polarity was reversed to the MOCNESS. We spent a few hours doing a hard re-termination of cutting off the outer and inner steel cables, making a new FIJI fitting, and then putting it through a stress test using a dynamometer and some lifting straps. Needless to say, it was a real triumph to finally get it back up and running.

Next up to fail were (simultaneously) the -80 chest freezer, CTD hydraulic power unit, dip net pole, and MilliQ clean water system. Thankfully, these fixes took less than two hours to completely rectify and were back up and running for the scientists that needed them before the next station sampling. Through it all, ResTech Kelsey has held it together very impressively and even kept us on schedule to potentially finish all of the sampling requirements before the end of the cruise. This is a good thing, as we are (naturally) about to hit some rough weather, which will likely slow down operations.

My post for next week will be composed from my own living room. I have a 9-day vacation coming up between this cruise and when I will be off on my next adventure aboard the USCG Healy en route for the Chukchi Sea in the Arctic Ocean. More soon!

Week 1-Into the Bermuda Triangle

 Such an incredible first week to this internship. I got the VIP tour of the R/V Atlantic Explorer from my mentor Nick Mathews the moment I arrived at BIOS (Bermuda Institute of Ocean Science), I got to meet the crew, my bunkmate Mason (who is level two technician that works for BIOS), and all the responsibilities a marine technician are supposed to oversee. Immediately starting the work day, I was helping scientists get gear placed on the R/V Explorer, and I helped with the pre-launch protocol for a cruise we were shipping out for in the next 18 hours. The research cruise was funded by a group of scientists called BIOSCOPE, compiled with scientists from six different research institutions. After pretesting all of our equipment and going through some safety briefings, we were off to explore the Atlantic!

Our transit to BATS (Bermuda Atlantic Time-series Study) took only five-ish hours to reach. Once we reached our way-point (GPS specific location), on the Atlantic, we immediately began operations. Marine Technicians have 12-hour shifts. I was scheduled to shadow Jillon (a level one technician) from 12:00 to 00:00 hours, while Mason handled the “night shift” which was 00:00 to 12:00 hours. So once we arrived at our desired location around 12:30, Jillon and I went to work.

Our 12-hour shifts were always filled with tasks. If we weren’t conducting a major operation, we were either helping out a scientist with a lab issue, or assisting the bridge with GPS connection issues, or just organizing our equipment in preparations for the next major operation.

My first operation was a CTD deployment/recovery at 14:30. A CTD is an instrument used to measure conductivity, temperature, and depth with various other devices connected to it. After deploying this behemoth of a tool, Jillon and I went up to the bridge to analyze and monitor the data. Our job was to make sure the data stream contained a good connection with the vessel so the scientists could use that data for their experiments. Seems simple enough, but when you have to send an instrument full of water sensitive devices and have to send them down to 1000 meters (roughly 3,000 feet) things can go wrong really fast.

Overall, my role as a Marine Technician on the Explorer was to assist with operations and fix/maintain instruments as the research cruise was underway. We were also responsible for Wifi, seawater flow, instrument success, transporting the data to the scientists, safely deploying/recovering VERY expensive instruments, and not contaminating any samples gathered at extreme depths.

By day seven, I was feeling extremely confident in my deck skills and getting familiar with the ship operations. The ship works as one unit, but within that unit contains more units that handle various responsibilities. Everyone is incredibly supportive of one another, and if someone is struggling, there is someone else there either trying to assist or just trying to help in whatever way they can. Several significant problems popped up on this research cruise that Mason or Jillon struggled to handle. But with the support from the crew and other personnel, they managed to complete the cruise with excellent results.

A special shout-out to the ships cooks SUCH INCREDIBLE FOOD! I could not believe the food Dexter, and Reggie made for the ship. Sushi, steak, lasagna (maybe the best I have ever had), perfectly crisped bacon, unbelievably fresh cookies, the list goes on and on. They made every meal count and bolstered everyone’s spirits. The crew on the R/V Atlantic Explorer is a solid one. Given some hardship in the past, they are making some excellent strides in what they are doing.

That’s all I got for this week. My apologies for posting late in my first week. Right now the ship’s network (WiFi) went down when we were at sea. We got back to BIOS and finally made a breakthrough today! Until next time everyone!

Week 1-Into the Bermuda Triangle!

Week Eleven: Spruce and Sea Spray

2230 local time

Hello!

This post is coming to you a bit later than usual and after a very eventful transit from the Scripps dock in San Diego to the OSU dock in Newport, Oregon. We left Tuesday morning with a full complement of ship crew members and 6 visiting researchers from the University of Minnesota. Their reason for being on board was unique in that they were studying human responses to ship motion and how this motion affects the motor functions of people who work at sea. Their study consisted of walking blindfolded in place with weights on your ankles, followed by several back-and-forth, 30-pace walks within a narrow, taped-off expanse of deck.

On the first day at sea, I gave the safety and ship orientation presentation for the first time followed by a survival suit tutorial. It went very well! Unfortunately, this would be the last day I would see all of the researchers in one room until we got close to port. This was due to some of the worst, pitching seas I have experienced. For a couple of days, we were reduced to 4-5 knots of speed as the bow was assaulted by one violent wave after another. This meant that the motion studies were put on hold as motion sickness abounded.

In the meantime, I busied myself with several projects. One project was to secure this plastic, tabletop material called starboard to an existing, stainless steel counter top. I was worried that bolting through the starboard would permanently damage the pristine stainless steel and could also allow for seawater seepage into the wooden counter underneath. My proposed solution was to make clamps that would prevent the starboard from moving while maintaining the existing counter. I also trimmed and sanded the starboard edges and placed rubber caps on all clamps. Now that the cleverly named MEZCAL cruise science members are on board, it’s nice to see this new surface in use.

Newport, Oregon is quite a lovely, seaside town. There are beautiful views all around, and the wonderful scent of spruce and cedar and salt spray. For all the horrid weather we experienced on the journey up, coming through the channel into Yaquina Bay was quite pleasant. A nice bonus was that the Roger Revelle was tied up on the NOAA dock just next door! It gave me the chance to see more of the town and reunite with some delightful people before they set sail the next day.

The last two days have been incredibly busy learning a brand new termination for 0.680 EM and loading for the upcoming cruise, including the largest piece of equipment I will be putting over the side to date. This is a MOCNESS, which I have seen before, but you will note the slight difference in scale below. You will note that the smaller model fits on a pallet, whereas the one for this cruise barely fits between the A-Frame.

I will also be taking back my familiar 0000-1200 shift again, and the science team will be standing 3-3 watches, so I will get the chance to meet and work with all the science team members. This also means taking command of deck operations using the A-Frame for the MOCNESS monster as well as the ISIIS plankton imager, the CTD, and a couple of vertical nets. Oh my! We will be out for the next 9 days and I imagine I will have a lot to update you with next week, toward the end of our cruise.

Happy 4th of July, and see you next Sunday!
