GLAD experiment CTD casts, northern Gulf of Mexico near DeSoto Canyon, July-August 2012

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.2012年7月至8月，研究团队搭乘RV Walton Smith号科考船，在墨西哥湾北部德索托峡谷（DeSoto Canyon）附近海域完成了43站温盐深（Conductivity-Temperature-Depth, CTD）剖面测量，该工作作为大拉格朗日部署（Grand Lagrangian Deployment, GLAD）实验的一部分实施。本次CTD剖面测量旨在获取上层水体的水文特征，以此表征该海域的中尺度与亚中尺度变化特性；同期该区域共投放297台CODE型海洋漂流浮标，以开展多尺度近海面扩散过程观测。该批漂流浮标均搭载1米水深的定深曳浮装置，其中绝大多数以三枚为一组投放，初始投放间距约为100米。本数据集由环境碳氢化合物输运高级研究联盟（Consortium for Advanced Research on Transport of Hydrocarbon in the Environment, CARTHE）构建。本研究依托BP与墨西哥湾研究倡议（Gulf of Mexico Research Initiative）提供的资助完成。
