Souls on Board

Well, we have a day under our belts. I can see the signs that of all onboard are slowly settling in.  The seasickness is dissipating as time goes on and the meds do their thing. The coffee is flowing and the stewards are nourishing us with delicious food.  Students are learning the pinrail diagrams, their watch schedules, and how to navigate around the boat, as well as, on the chart in the doghouse.

We are starting to settle into our science schedule as well. Last night we towed our first Neuston net, a one meter net that cuts through the surface of the sea sampling the air-sea interface.  Apparently, the bioluminescence was alight and there were dolphins swimming by like glowing torpedoes and checking out the net.

This morning, we had our first morning science station. We deployed our CTD (conductivity i.e. salinity, temperature and depth) down to 325 meters on the hydrowire.  We also deployed a phytoplankton net, a secchi disk, another Neuston, and collected a surface sample.  This station was the first of, hopefully, a daily sampling of our cruise track from the south island of New Zealand to Tahiti.  Our cruise track is a unique one and there isn’t much data available other than the two previous SEA Semester cruises.  I look forward to seeing the environmental changes as we continue to make our way along.

As I write this in the library on the Seamans, I am sitting next to a large chart of the Pacific Ocean. I am constantly blown away by how big of an ocean it is. We are lucky ones to be able to explore a slice of it.
