Souls on Board

Despite some bouts of seasickness, it was smooth sailing all through the night. To quote our captain, she moved “like a bar of soap slipping across your bathroom floor.” At 1030 this morning, we deployed the CTD (conductivity, temperature, depth) for the first time, and collected a lot of salps! According to Molly, salps stand for “snacking and lunching on plankton sludge.” While that may be true, they are also hermaphroditic tubular shaped gelatinous organisms, that can exist as a single polyp or in a colony.

A current research project is looking into whether or not they vertically migrate in the water column from day to night! At noon, our calculated rhumb line was determined to be about 108 nautical miles. This means that we have traveled 140 nautical miles in a straight line from noon yesterday to noon today. Watch groups and schedules have also been running more smoothly, like a bar of soap slipping across your bathroom floor, with everyone learning the ropes (literally).

We arrived in the majestic Whangaroa Harbor at about 1430 today. Steward Sarah and her trusty sidekick Tim made some wonderful meals with seasickness in mind. They also hit us with some stellar pizza, following the flawless execution of what is named a “Sierra Charlie.”

For all you landlubbers, a Sierra Charlie is one of the most critical components of any successful voyage. It is what you would all call a classic “dip in the water”, the difference being you do it jumping from the bowsprit of a 134-foot brigantine. There were games played, mid-air animal impersonations, as well as some gentle peer pressuring to get everyone into the water (…Jeff…). The day is currently finishing with some smooth guitar tunes and hanging out on the science deck with Tim and Molly.

P.S.: Hi mom (and friends)! I'm sunburnt, but so is everyone else.
