Abstract:

43 CTD casts made from the RV Walton Smith in the northern Gulf of Mexico near DeSoto Canyon in July-August 2012 as part of the Grand Lagrangian Deployment (GLAD) experiment. These CTD casts were made to determine the hydrography of the upper water column as one way to characterize the meso- and submesoscale variability in the region where 297 CODE-type ocean drifters were launched in an attempt to measure multi-scale near surface dispersion. The drifters were drogued at 1 meter and most of them were launched in triplets (initially separated by roughly 100 meters). This dataset was created by the Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE). This research was made possible by a grant from BP/The Gulf of Mexico Research Initiative.

Purpose:

These CTD casts were made as part of the GLAD experiment to determine the hydrography of the upper water column as one way to characterize the meso and submesoscale variability in the GLAD experiment region.
