Summary
----------------------------------------------------------------------

59 CTD casts made from small boats launched by the RV Walton Smith in the
northern Gulf of Mexico near DeSoto Canyon in July 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).
