Near-Surface Current Shear from Multiple Instruments, Submesoscale Processes and Lagrangian Analysis on the SHelf (SPLASH), northern Gulf of Mexico, 27 April 2017

As part of CARTHE's SPLASH (Submesoscale Processes and Lagrangian Analysis on the SHelf) experiment, current observations were obtained from a variety of instruments in the Louisiana Bight, northern Gulf of Mexico. On 27 April 2017, between 17:00 UTC and 22:00 UTC, six types of measurements at various depths were taken, which in combination provide the near-surface current shear in the area 89°38.29' W - 89°41.25' W and 29°9.83' N - 29°10.65' N. This dataset contains the current measurements obtained from (1) thin bamboo plates at 0.9 cm depth; (2) an undrogued LASER-style drifter at 1.8 cm depth; (3) a drogued LASER-style drifter at 30 cm depth; (4) polarimetry valid at 0.8 cm - 4.9 cm depth; (5) the ADCP mounted on the autonomous REMUS for depths between 0.18 m and 3.77 m; and (6) the bottom-mounted ADCP from the research vessel Walton Smith for depths between 4 m and 13.5 m. In addition, the velocities obtained from a theoretical Stokes drift profile are provided for the top 1 m in steps of 0.1 cm.
