GLAD experiment CTD casts, northern Gulf of Mexico near DeSoto Canyon, 2012-07-21 - 2012-08-01, R/V F.G. Walton Smith cruise WS1211

43 CTD casts made from the R/V Walton Smith in the northern Gulf of Mexico near DeSoto Canyon 2012-07-21 - 2012-08-01 (F.G. Walton Smith cruise WS1211) 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.本数据集包含2012年7月21日至8月1日期间，由R/V Walton Smith号科考船在墨西哥湾北部德斯托托峡谷（DeSoto Canyon）附近海域开展的43次温盐深（CTD，Conductivity-Temperature-Depth）剖面测量，所属航次为F.G. Walton Smith号WS1211航次，系大拉格朗日部署（Grand Lagrangian Deployment, GLAD）实验的一部分。本次温盐深剖面测量旨在获取上层水柱的水文特征，以此表征该区域的中尺度与亚中尺度变化；同期该区域共投放297台CODE型海洋漂流浮标，以实现多尺度近表层扩散过程的观测。该批漂流浮标均搭载1米层定深浮子，其中大部分以三联组形式投放，初始间距约为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）编制完成。本研究依托英国石油公司（BP）与墨西哥湾研究倡议（The Gulf of Mexico Research Initiative）提供的资助得以开展。
