Hi all,

This week we finished up mooring recoveries and have started our transit back home. We’re heading home early because we had great weather during science operations and needed no weather delays. There’s a hurricane coming through the North Atlantic and we have altered our route so that we can avoid as much of the bad weather as possible. Because of that we are sailing through a big chunk of ice country, and the captain has requested that I assist watches on the bridge from 10pm to 2am so there are extra eyes looking for ice.

The last flanking mooring recovery went as usual, however, operations changed when it came time to recover the surface mooring. Typically we bring the buoy on first and then the cable, however, since the surface mooring has  a large buoy and it’s the last buoy to recover there wasn’t much deck room. So we triggered the acoustic release and deployed the rescue boat to attach a tag line to the end of cable to bring the cable up first and the buoy last.

During deck ops for the surface mooring recovery I helped pull in the synthetic line that was at the base of the mooring as well as operate the winch that was spooling up the mooring’s cable.

Once those operations were over and we were transiting back to WHOI, I finished a label project that I had started earlier in the cruise. In the transducer room, where most all scientific transducers are, I created permanent labels to show type of water (fresh or seawater) and direction of water in the pipes. (The new labels look pretty good, if I say so myself!)

We’re hitting some weather today, but we plan on being back at WHOI in about a week’s time!

Hi all,

This first full week of science operations has been a busy one!

On Day 8 we finally made it out to the Irminger Sea Array and deployed our first mooring – the surface mooring. During the deployment, the first mate called me up to the bridge two times because there were long finned pilot whales all around the ship – I swear they were following us! One of the scientists, has a drone and he flew it out during the mooring ops and  got some great footage of the whales and the R/V Armstrong (and of course the mooring ops)!

A scientist adapted a spare acoustic communications device so that his modified one can be deployed in the water and talk to the moorings and collect data  autonomously. After mooring ops are done each day we have been deploying his instrument to test its range and how good it can collect the moorings’ data.

Between mooring deployment and recovery three sea gliders were deployed with the intent of collecting and transmitting mooring data over the course of a year.

The night before we started mooring recovery, the night of Day 12, we did an EK80 survey of the mooring locations to make sure that the buoys and instrument cages were at their respective depths. The EK80 is a sonar and when in use over the moorings there is a strong return at each of the buoys/instrument cages. We can then see what depth those returns occur at and verify with what they should be based on the mooring structure and water depth at that location.

So, by today, Day 14, we have deployed all of the new moorings, deployed all sea gliders, and have recovered two of the old moorings.

A couple days ago, a leak was noticed in one of our underway seawater pump’s housing, so we need to replace the whole pump. I have been helping out the third engineer with replacing this pump. We first removed the pump and are now cleaning up and priming the stand where the spare pump will go. In the next couple of days we will actually replace the pump.

Joe and I have started having daily Linux lessons to help familiarize me with the system as well with the servers that we work with on a daily basis. I have also been reviewing and editing instruction sheets for operating and data recording on some of the acoustic instruments, like the multibeam and the EK80.

In my down time I have been watching Planet Earth II with some the crew!

We still have ~3 more weeks  to go – stay tuned.

Hi all,

Although we have been transiting for a week and there has been hardly any science operations, myself and others in the SSSG (Shipboard Scientific Support Group) have had a lot to do. Not necessarily because we’ve been swamped with work but also because we have had the time to work on things since there hasn’t been any scientific operations. I’ve helped:

• Fix leaks in underway seawater systems
• Re-terminate the CTD cable
• Turn on the acoustic instruments and edited procedures on how to turn on, operate, and save data from the instruments

Personally, I have been familiarizing myself with the Linux system, as well as its formating and commands.

On Day 5 we made it to deep enough international waters where we could do some tests on the acoustic releases that will be deployed with the new moorings. The science party attached acoustic releases to the CTD and brought it down to ~1000 m where they then attempted to communicate with each release to see if it’s functioning. Then once the CTD was back on deck they checked the release mechanisms to ensure that the acoustic releases are fully functional before they attached them to the new moorings. Everyone was anticipating the CTD station because there have been 0 science operations for the past 4-5 days.

This past night I was allowed to assist watch on the bridge from 1800 – 2400 and received a crash course in bridge related topics/instrumentation from the 3rd Mate. It was a great opportunity to learn about ship operations. I plan on assisting more watches on the bridge throughout the rest of the crews.

On a side note, the most wonderful thing happens aboard this ship at 2:30pm every day, and that thing is Cheese Thirty where we are all blessed with divine cheese and meat platters by our gracious stewards! Also, some scientists are crossword enthusiasts (as am I) and we all have been doing crossword puzzles in our downtime.

Early tomorrow morning we finally arrive at the Irminger Sea Array and can finally start science operations! More exciting news to follow.

P.S. Sorry for the lack of photos, I was having a hard time uploading them with my current internet connection.

Hi all, my name is Lauren Kowalski and I’ll be interning aboard the R/V Neil Armstrong!

I am a recent graduate from the University of Washington with a B.S. in Oceanography. Up until now I have gathered about 12 weeks of ship time aboard various research vessels as a part of the scientific party. Now as a marine technician intern, I have been given an exciting opportunity to expand my knowledge and experience and work as the interface between the ship’s crew and the scientific party.

My internship will be focused on recovering and replacing moorings and other scientific instruments from an OOI site off the coast of Greenland called the Global Irminger Sea Array! (I really hope we get close enough to see land!) OOI stands for the Ocean Observatories Initiative, where ‘underwater observatories’ have been established at different locations across the globe. Each site includes a number of fixed scientific infrastructure at the seafloor and throughout the water column to collect real-time data. In addition to the fixed infrastructure there other scientific instruments deployed by scientists aiming to collect data on a specific aspect of that site.

Quite fortunately, while at UW, I had the privilege of working at another OOI site called the Cabled Array which is located off the coast of Oregon. In fact, I completed my senior thesis using data collected from a methane seep site, called Hydrate Ridge, which is one of the sites within the Cabled Array.

Now I get to continue my involvement with OOI in a different ocean at a new site with different oceanic processes!

I am very excited to have been given this opportunity and I can’t wait to share my experience with you!

Lots of pictures to come!
