Working in an Unpredictable Sea

Yesterday found me standing on the aft deck of Falkor, gripping a rope to hold the swinging CTD rosette steady as we lowered it over the side...

CTD’s Away!

Our first day of sailing consisted of voyage preparation. This included tying everything down and expecting the worst sea conditions. Pete and I managed to...

Catching the Wave!

A very big part of this project depends on a piece of equipment called the ADCP (acoustic Doppler current profiler). This is one of the...
