It’s a swell day for science today on the Robert C. Seamans...just like any other day, except today the conditions have provided us a good southwest swell to keep us on our toes. We had some strong winds this morning and it’s been gradually lying down, but the science deployment this morning was definitely sporty! The hydrocast rocked and rolled a bit in the swell. Our plankton net kept trying to surf in the waves. Dusky dolphins even came out to surf around the net and a seal pup was incongruously porpoising alongside, too.
One of our coolest pieces of scientific equipment is our carousel. Every day, we deploy our carousel on the hydrowinch, sending it down a few hundred meters or more to gather information about the water column. The carousel contains a lot of instruments that provide continuous data on temperature, salinity, oxygen, light and various other interesting environmental factors. The twelve Niskin bottles on the carousel are programmed to close at specific depths allow us to collect the water at various depths and do even more analysis from there. The actual deployment, called a hydrocast, is pretty involved and requires a lot of planning and coordination between deck
and lab. The students are quickly learning how to take over and ‘call’ the deployment and sail handing to get us on station. They’re mastering the routine and assuming leadership in lab, as well as on deck. It’s impressive how much they learn in such a short amount of time!
Our Secret Santa Christmas celebration continues, and today I got my gift. It was a lovely ball cap from the Pequot Museum (so I do have a suspicion who gave it to me, as only one of our crew works for the Pequot Museum.) but we’ll wait for the big reveal at the end. Meanwhile, everyone’s crafting and planning away on the gifts coming up. It’s fun to celebrate the holiday of giving every day.
All my best to y’all at home! Hope it’s not too cold; does it make you feel better if I tell you we got snowed on yesterday? So much for the quest for eternal summer!
