Abstract:

This dataset contains underway Acoustic Doppler Current Profiler (ADCP) data collected during R/V F. G. Walton Smith cruise WS19159 in the Gulf of Mexico from 2019-06-08 to 2019-06-23. Data were collected as part of a mission to satellite tag adult control and oil exposed mahi-mahi (Coryphaena hippurus) and characterize the habitat where they were captured. Data included here are flow through underway (surface water) environmental data and underway ADCP data collected for the duration of the cruise. Underway current velocity profiles and surface water characteristics document the lateral distribution of salinity, temperature, and chlorophyll. The raw ADCP data were collected and processed using the University of Hawaii data acquisition system (UHDAS) during the cruise. The post-cruise data processing was conducted using the CODAS (Common Ocean Data Access System) processing. This dataset contains both raw and processed data. There were two vessel-mounted ADCPs on the Walton Smith operating at 75 kHz and 600 kHz, respectively. Both were manufactured by RD Instruments. This dataset was created by the RECOVER (Relationships of Effects of Cardiac Outcomes in fish for Validation of Ecological Risk) Consortium and was made possible by a grant from the Gulf of Mexico Research Initiative.
