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
