Raw current velocity profile data from Electro-Magnetic Autonomous Profiling Explorer (EM-APEX) floats collected aboard R/V Walton Smith cruise WS17121 in the northern Gulf of Mexico from 2017-05-02 to 2017-05-17

This dataset contains raw current velocity profile data acquired from Electro-Magnetic Autonomous Profiling Explorer (EM-APEX) floats deployed via U. Miami R/V Walton Smith cruise WS17121 in the northern Gulf of Mexico from 2017-05-02 to 2017-05-17. Period of the record is for the first 10 days of operation during a cold front passage. The first day of record for each float ranges from May 2, 2017, to May 7, 2017. Technology for measuring subsurface ocean currents is available using the EM-APEX sensors recently developed by Teledyne Webb Research and the University of Washington. Velocity measurements obtained from electromagnetic current sensor pairs. Sampling rates were changed by updating mission profiles from continuous to profiling modes between specific depths by changing the piston counts on the missions via Iridium remote sensing when the float reaches the free surface. Related raw temperature, salinity and biogeochemical profile data are available under GRIIDC Unique Dataset Identifier (UDI): R5.x275.000:0002 (DOI: 10.7266/7QQF9969).
