Abstract:

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.

Purpose:

In order to better understand the physical processes relevant to the transport of oil and marine debris, the current vector profile (defined within 1 cm of the air-sea interface) was observed.
