Gulf of Tehuantepec
We spend the day transiting the famously capricious Gulf of Tehuantepec, but today winds were calm, and we were able to cut across the bay in good time. At the southern end of the gulf is an underwater seamount, so we maneuver the Sorcerer over the seamount in hopes of encountering an upwelling. An indeed there are numerous dolphins in the area feeding on fish. We take a CTD sample just as the sun is setting, and I spend the rest of the evening processing the filters.
