Abstract:

Underway data were collected by shipboard flow-through system and other onboard instrumentation. This includes: water temperature, salinity, chlorophyll, beam attenuation, GPS, wind speed and direction, surface PAR, air temperature, barometric pressure, relative humidity, echo sounder. Data were collected in the northern Gulf of Mexico from October to November, 2015.
