Arctic GEOTRACES Week One


The USCGC Healy sailing out of Dutch Harbor, Alaska into the Bering Sea (August 9, 2015).

And we’re off!

The U.S. GEOTRACES Arctic expedition departed Dutch Harbor on August 9th onboard the USCGC Healy. Shortly after departure we had our first safety drill. Everyone onboard has to practice putting on immersion suits which are kept on the boat for an emergency situation that would force us to abandon ship and jump into the water. The suits are bright orange with a flashing light and whistle, and the back has an inflatable pouch for flotation. There is a rubber cap that goes over your head and hugs tightly around the neck to prevent water from flooding the suit. The shoulders of the suits have clips to attach to a neighbor, in the water we would hook our suits together and form a giant circle of bodies that would be easier to spot from the air.

After day one I am medication free, unless we run into harsh weather (>20 ft seas make me slightly queasy). Everyone handles seasickness differently. I am lucky to be able to adjust to the motion, but others, even those who frequently go to sea will continue taking medication throughout the cruise. Over-the-counter Bonine and Dramamine are the most common medications used onboard. For extreme motion sickness there is the prescription-only “Coast Guard Cocktail” which is a dose of promethazine (a mild sedative) for anti-nausea, paired with ephedrine to keep you awake. Fortunately, the Bering Sea has been kind to us this week with calm seas and fair temperatures between 40-50 °F.
