Abstract:

This dataset contains raw Acoustic Doppler Current Profiler (ADCP) data collected aboard the R/V Point Sur for cruise PS19_04 in the northern Gulf of Mexico from 2018-07-18 to 2018-08-01. The dataset also includes trawl field data collected during this cruise and includes information on trawl ID/number, cruise name/number, types of gear used, station, sample, date, location (latitude and longitude), time, depth, temperature, salinity, the volume of water, net mesh size/units, and related comments. The overall purpose of the R/V Point Sur cruise PS19_04 led by chief scientist Dr. Tracey Sutton is to perform deep water sampling of in-situ seawater and associated fauna.
