Abstract:

59 CTD casts made from small boats launched by the R/V Walton Smith in the northern Gulf of Mexico near DeSoto Canyon in July 2012 as part of the Grand Lagrangian Deployment (GLAD) experiment. Samples were collected 2012-07-22 - 2012-07-31. 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 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).

Data Parameters and Units:

Each CTD cast ASCII file contains these variables: Column 1 = date (YYYY-MM-DD) Column 2 = time (HH:MM:SS) Column 3 = depth (meters) Column 4 = temperature (degrees Celsius) Column 5 = salinity (PSU)
