System Description - Sea Water Intake

Sea Water Intake
Surface water properties are obtained by pumping near-surface (~2m) water from below the hull, through a small (~2in) sea chest, up to an instrument package on the car deck that includes a debubbler, salinity, dissolved oxygen and chlorophyll sensors. Installation of sea water intake was performed during the P.T. Barnum's dry dock period.

Bottom (lower) and port side (upper) of hull showing route sea water traverses to car deck (out of the picture at the top). Note that ADCP is just out of the picture in the foreground.	The sea-water intake emerges from the hull below onto the car deck (lower portion of picture) where it feeds water into the salinity, dissolved oxygen and chlorophyll sensors that are housed inside the gray boxes.
