Holiday at Sea- Week 1

04/07/16
Holiday at Sea

Happy 4th of July from the USCGC Healy! Today marks day 3 on our expedition to the Arctic and things have been going smoothly. We have been sailing southwest along the Aleutian Trench since the day before yesterday and I anticipate we will make a right turn into the Bering Sea sometime in the next day or so. Since today is the 4th there are a few activities scheduled: the crew will kick off a cornhole tournament (possibly ping pong) and there will be some sort of “pyrotechnic training”. There is also a USA themed movie marathon on the ship’s tv channel.
Since getting on board, I have slowly been able to find my way around the ship both physically and on the various networks we have here. Step one was finding the route(s) between the computer lab, stateroom, and mess deck. From there I could begin mounting troubleshooting strategies for the various instruments we have here. 
Much of the work we have done so far is to make sure that these instruments are sending accurate data to the right place. If you want a visualization any of these, they are usually a black cylinder with various tubes and plugs leading in and out. Yesterday I checked that the fluorometers (which measure how much chlorophyll is in the water) were calibrated and sending that data to the right port on the network. I later checked to make sure the configuration file for the computer that runs the instruments on the CTD (a water sampler that also measures conductivity, temperature, and depth) was set up so that the serial numbers matched. And the day before we left Seward my mentor, Croy, had me change a gyro on the gravimeter in the bottom of the ship. I worked very carefully since it was one of the more sensitive (and expensive!) instruments on board. It made a full recovery with its new gyro. You don’t often get to work with the guts of a gravity meter.
I’m learning alot obout the serial interfaces between instruments and computers as well as the myriad software that parse the data. Day to day duties involve looking at all the various fires and then trying to put them out, which keeps things constantly changing. 
This also reminds me: We had our first actual fire alarm yesterday! Nothing major, but since it was a few hours after the first drill it caught a few by suprise. 

Perhaps next week I’ll be able to say that everything is running perfectly. However I’m dubious, plus we will be at our first station by then so I’ll have some updates.

Until then,
Nick

Quiet times

Hello everyone,

   I have been continuing on with my internship here in Bermuda.  We have only gone out on a few cruises and they have been pretty short (though everything will probably seem short after a 45 day trip!) but still full of new experiences for me.  We just returned from a one day cruise that was a deep CTD cast and the recovery of an incubation chamber that we had put into the water three weeks ago but the whole trip was fairly uneventful.  I have very quickly learned that “uneventful” is a wonderful magical word when describing research cruises and it means that everything went smoothly.  Nothing broke down, everything went into and out of the water as it was meant to, no one was injured…uneventful in the best way possible. 

During our time on land we have delved into several projects that have kept us busy.  we walked through terminating the end of our CTD cable which I have mentioned before.  It is a long process but a very important one and it was nice to get a really good tutorial about the process.  On Monday we will terminate the actual cable instead of a practice one so I will try to include some pictures for the next post.   We have also been working on the CTD itself making sure it is all ready to go for the cruise next week.  There are 12 different sensors on our CTD so we have to make sure that each one is within its calibration date, is functioning properly, and that everything is very securely attached to the CTD.  Sounds pretty straight forward but it can become several long days of work if things don’t go smoothly. 

I was also fortunate enough to get invited to see some of the behind the scenes action involved in operating a glider.  These gliders are loaded onto a ship and brought out to open waters where they are  slipped into the water by hand.  From there all of the action is back in a lab office at BIOS.  The scientists have programmed “missions” into the glider and can send it commands from land.  In the beginning the test commands are “dive to 5 meters and surface” and then “dive to 60 meters and surface”.  The science team monitors the activity to make sure that all of the sensors are recording properly, that the glider is moving the way it should, and that it is following the commands it is given.  Once the testing phase is done then the glider receives a longer mission that it completes on its own.  It will dive to 300 meters (for example) come up to the surface and transmit the data before changing position and diving again.  The gliders can stay out in the ocean for months at a time collecting data before being recovered.  They are pretty amazing little fish.  I wasn’t with the team when they launched the gliders but it sounds like I will get another chance to see it later this month so hopefully I can grab some pictures.

Speaking of pictures I wanted to get a few out there of the back deck of the R/V Atlantic Explorer.  In my last post I mentioned it being a wet deck and if it was anything except for the calmest conditions we would get big waves over the side.  Here are some pictures from our last cruise to tide you over before my next chance to take some more.

Until next time!

Blog 3, Final

Blog update 3

After a ten day journey, I have finally returned home. My journey has been an incredible experience. The USCG crew flew their way across the Pacific Ocean and arrived at Seward Alaska 1 day ahead of schedule. The ship couldn’t dock at Seward the day we arrived because it was busy unloading containers from cargo ships.  Instead, the coast guard arranged flight ops with the air operation division in Kodiak, Alaska. For most of the day, a helicopter landed and took off from the ship helipad to practice in case there was an emergency. I was able to come close to it and take some pictures.

In general I really enjoyed this trip. I love that I learned so much about while under way on the ship. Andrew and Kyle were amazing people to work with, very helpful, intelligent and all around good people. Casting the CTD was one of the most fulfilling part of the trip. Me and Kyle worked on having it ready for a test cast. We installed an altimeter, flourometer and transisometer to the CTD. All nerves ended when the CTD came out of the water and all its components came up. 

The adventures I had on this internship will stick with me for a long time. From getting sea sick the first day of the trip to walking out the door and seeing land for the first time after they voyage. Adventures and experiences like this are the reason why I really want to be a Marine Technician. Apart from cool adventures, helping out troubleshoot a machine that goes up to 4000 meters under the sea is also fulfilling. I hope to one day, find a job where I can assist marine scientist with their electronics while under way in missions.

I would like to thank the crew of USCG, Andrew and the marine tech, Nandita at MATE and everyone else who helped me receive this internship.  

Introduction and Anticipation

Introduction and Anticipation

Hi all, my name is Nick Benz and I will be sailing on the USCGC Healy for the next six weeks. In approximately eighteen hours I will have finished packing and repacking, and then board my first flight on my way to Anchorage. I’ll then board the Alaska Railroad south to Seward, where the US Coast Guard Cutter Healy is docked. From there the opportunity of a lifetime will begin. 

I have had a bit of experience working on research vessels, but I expect Healy to be unique because it is a Coast Guard ship. Also, I have learned that the primary goals of the cruise will target the biology of the focus sites. My background is in geophysics so I’m sure there will be a learning curve for becoming familiar with the intricacies of the survey methods. This should make for fairly exciting blog posts. 

By this time next week I will be able to report those details. For now I would like to thank those who were instrumental in my attaining this awesome internship. I am honored.

Pre-Internship Blog Test

Hello all,

My name is Alex Hamm and I am an electrical engineering undergraduate student at the University of Wisconsin-Milwaukee. I will hopefully be serving on the R/V Sikuliaq from June 27-July 8. Unfortunately, the ship has been having some power distribution problems and the cruise is on hold. A final meeting will be held either Monday or Tuesday night to determine if the cruise is a go. I am flying into Victoria, Canada and if all goes as planned will be returning to Seattle, WA. Hopefully by my next post I will have a better idea as to what exactly the plan is for the coming days.

USCG Healy Internship – Post 2

   

      I arrived in Honolulu on June 19th after a grueling sixteen hour travel day that started at 2:30 AM in Boston, Massachusetts. My first two days aboard the Healy were spent in port, where I used that time to familiarize myself with the ship and got to know my fellow companions that would be accompanying me on the voyage. Once we left port, my mentor Andrew Woogen had us set-up and trouble-shoot both flow-through systems connected the the Science Seawater System. The main flow-through system went together rather painlessly, but the flow-through in the wet lab was not so easy. Everytime we were able to get the sensors related to the TSG box online the other sensors would seem to cut out and stop working. Once we ironed out the problem, all the sensors in the wet lab came back online and we then began to organize and label the rats nest of wires that were associated with the flow-through system.

    The following day we were met with much rougher seas and my fears of becoming seasick finally  vanished. I had no problems tolerating the rough conditions and actually found the situation rather exciting. The task of the day was to install and connect all the necessary sensors associated with the CTD.  My duties included installing the altimeter, the PAR sensor, and mounting and installing the transmissometer. I was also shown the basics of how the software associated with the components onboard the CTD work and how all the instruments are programmed. I ran into some trouble finding all the correct wires necessary for each sensor, but with the help of my mentor together we were able to source all the appropriate cables and get the CTD completely wired up and ready for a connection test.

    Since the cables for the CTD were difficult to find and some important ones were scarce, the following day I was put in charge of categorizing, organizing, and inventorying all of the CTD cables aboard the Healy. I decided to organize everything first, then when through and created a spreadsheet and checklist of everything we had, and what we needed. In my spreadsheet I noted that the cables I inventoryed were only the ones that I deemed “Plug and Play” or “Complete”, being that a majority of the cables have been cut or spliced at some point. My mentor also suggested that a particular Y-cable that would run both the fluorometer and the transmissometer off of one connection would be helpful in future deployments of the CTD. My second task that afternoon was to source that particular Y-cable using Sea Bird Electronics website as a guide. I was able to narrow my search down to two options of cable that I believed to be the correct ones for the application. Since I wanted to guarantee I had the correct cables, I decided to email Sea Bird Electronics to ensure I had the correct ones. 

     My mentor was pleased with the way that I organized and inventoried the CTD cables, and suggested that I email my spreadsheet/checklist to an incoming marine technician so he could get a head start on gathering the required cables for his future research mission. At that point, I hadn’t heard back from Sea Bird Electronics on whether I had the correct cables or not, so I decided to email the incoming marine tech the two cables that I thought were the correct ones, and noted that I wasn’t one hundred percent sure they were the proper cables. I also added in my email other necessary supplies that we knew we in need of.

    I look forward to updating this blog later on this week or sometime early next week as we cruise toward Seward, Alaska. At some point we are supposed to start in on the Science Seawater System so in the next installment of my blog I will hopefully have some good info and experience with that equipment. 

    Stay Tuned–

Week 5 Aboard the R/V Sharp

Since my last report, we are currently steaming offshore to begin the final leg of the cruise. I have received a request, from one of the scientist, that had to depart from us following the 3rd leg of the cruise. He wanted me to try, and monitor the flow through system on the ship every 6 hours instead of once a day. In our transient back to port, I had discovered small organisms that had been trapped in the filter, of the ships flow through system. I collected them, and took them to Scott (the scientist on board that studies planktonic organisms). He put them under the microscope, and identified them as Pteropods, Limacina, Foraminifera, and Amphipods. He had a particular interest in the Pteropods, because he wants to conduct further studies on their abundance. The Pteropods play a major role in balancing ocean acidification. Scott stressed, that if these organisms were to disappear the levels C02 in our atmosphere could likely be effected. On this final cruise leg, I will be monitoring the filter for their presence, and record the Lat/Long, of the general area they were collected in.

On this final leg, of the cruise, we are getting the chance to perform more CTD cast. KG is allowing me to prepare the CTD for deployment, and record, as well as process the data. A salinity sample is also collected every 12-hour period. CTD cast were suspended through several days, of the cruise, due to sea state conditions. One of the important skills I have gotten the chance to assist with, is performing a termination on the EM cable and CTD unit. We had to re-terminate it, because the CTD jumped the sheave during a cast in rough conditions, and damaged the cable.

Things have been running smooth, so far on the final leg of the cruise. We will continue to alternate HAB CAM operations, with deploying dredges. Also, the science team has scheduled CTD cast at certain locations.

Till next time,

Pre-internship blog

Hi my name is Gerardo Acosta, a student from Long Beach City College. I have been given this chance to participate in the MATE internship. This internship is a great opportunity and I intend to take full advantage of it. This is the first of my blogs that I will do throughout the two weeks I will be at sea on board the USCG Healy. To begin with, going into this internship I feel it to be a bit intimidating. The science coordinator, David and I had a phone call in which he briefly discussed my job on the ship. We talked for about thirty and while on the phone I typed notes on my laptop of the details about the job so that I can research specific components at a later time. When I talked with David, I was able to speak with Kyle Yusen who is the other intern that will be joining me on the cruise.  Kyle Yusen sounded like a very intelligent and friendly person. I look forward to working with him on this cruise. David briefly explained to us the complex system of piping that Kyle and I will be working on. The components I will be working on for the ships vital information system that the crew needs in order to make decisions for navigation. The whole idea of this cruise seemed very intimidating for several reasons. One, the people I spoke with were well education and had lots of experience. The last reason is because the moment I learned that I received the internship, I researched the history, missions and accolades of Healy. I googled the name and clicked on the first Wikipedia page. The first sentence on Wikipedia read, “The United States’ largest and most technologically advanced icebreaker“. This gave me the idea that work here will be serious because one, I will be working with US coast guards, two, even if it’s just an internship I will need to give it my full attention to have correct data for the ships navigation, and three because I feel like I have a duty to do my job with zero mistakes to get our ship to safely cross the ocean. When I finished talking on the phone with David, I was under the impression that he had lots of experience and that if I had any question about the trip he would answer. Also, after telling my professor at Long Beach City College about this cruise, he told me to just focus on my work and try to get as much experience as I can in this trip and if I had any questions to no hesitate to call and ask him.

A few days later Nandita the MATE internship coordinator called me to conduct a phone interview and discuss the details of my flights and travel plans. Nandita was very helpful when it came to setting up travel plans. The plan is to leave from LAX to Honolulu and meet up with the rest of the team. Then conduct all emergency details required to be on the boat. Then, be on our way for our cruise and arrive at Seward Alaska. There, we take a train to Anchorage with Andrew Woogen and Kyle and then catch our individual fights back home. In this cruise I will give it my best and gain as much experience as possible to someday get that dream job.

After this cruise my goal is to use this experience to get a job in the field. Most importantly though, I will try and network with ship crew members to see if they would happen to know any opportunities to actually work with them and getting paid full time to conduct research on the ship. Over all though I think this will be an excellent work experience opportunity. My dream job involves doing something I love to do. Being able to travel the world while working in the field I studied is life goal.

 

 

BATS Cruise

So after returning from our short one day cruise out to our hydrostation, we spend a couple days prepping everything up for our BATS cruise (Bermuda Atlantic Time Series). This is a 7 day cruise that takes place once a month and is one of the longest running oceanographic time series. So far we have been out 5 days and aside from a few minor set backs, everything has been running smoothly.

The first issue we encountered was an oxygen senor with our CTD. For some reason it would only work below 20 meter, and after tinkering with it we only made more issues trying to fix this one. After a while we called it a wrap and put the CTD back to its original setting and just left the issue to deal with at the dock because we did have a secondary sensor that worked just fine.

After a few days of deployments we encountered our second problem which was our COM7 winch that we were using to tow our MOCNESS. We were performing a test run without collecting samples and while we were towing the device back in our winch kept tripping its breaker and shutting off mid recovery. Luckily this was the test run and we did not deploy it too deep but it was an extended effort to get it back on board.

Aside from that the trip has been a great success. We’ve had a very successful MOCNESS operation were all 8 nets collected great data and with this particular device, that can be difficult. The MOCNESS is comprised of 9 nets that are triggered electronically to open one while closing another to collect plankton samples at varying depths.

Unfortunately this is my last blog because my internship will come to an end next Tuesday (June 21st). I wish I could stay much longer but am very grateful for the opportunity that I have been given to be an intern at BIOS (Bermuda Institute of Ocean Sciences). I have gained so much knowledge and experience in just the short 6 weeks that I have been here. I will attach a last picture when we make it to shore because it would probably take the rest of the trip to upload anyway haha.

All the best,

Mason Schettig

Week 4 Aboard the R/V sharp

Since I talked to everyone last, I received a great opportunity to go aboard the new research vessel, the R/V Neil Armstrong. KG, Chip, and myself were allowed to give ourselves a self-guided tour of the vessel, and had the chance to briefly talk to one of the technicians on board. We were also allowed in the warehouse to view the Alvin, and talk to one of technicians there as well. The Alvin is transported, and deployed from the R/V Atlantis, which was also in port at Woods Hole at the time.  

Currently, we are out to sea on our third leg of the cruise plan. We have been using both the HAB CAM, and NOAA scallop dredge system for data collection. When the CAM is being towed, it allows for some free time, so I have continued to work on creating system schematics for KG. Also, we have spent some time trying to trace, and label the wire feeds, which run power to the deck lighting and doghouse locations. I also got tasked, with giving a tour below deck, to one of the scientist on board. He wanted to see the underway flow through, and how it worked.

I have really had a great experience aboard the R/V Sharp, so far. The crew has been great, and everyone on the science team is very nice as well. I have enjoyed talking to the science crew about their experiences, and backgrounds. Most of the science team is made up of NOAA, and Woods Hole employees. We will be making our way back to Woods Hole in a couple of days, to pick up a new group of scientist, for the final leg of the cruise. Hopefully, things will continue to run smooth, and on schedule, for the duration of their fisheries survey.

Till next time,

Chris Petroff
