CTD Hydrographic data from Cruise OC468, LA, MS, AL Self Break, August and September, 2010

Hydrographic data were collected during cruise OC468 using a CTD-rosette system aboard the R/V Oceanus. Our objectives were to collect water column and benthic samples in the Northern Gulf of Mexico immediately following the Deepwater Horizon incident. This cruise was funded by the Biological Oceanography Program at NSF and was repurposed to explore the impacts of the spill and to provide a platform for investigators with rapid response funding from NSF. The ship departed Gulfport MS on 08/21/2010 and collected samples at sites near the wellhead as well as to the south and southwest of the wellhead before returning to Gulfport on 09/16/2010.

本数据集的水文数据采集自“海洋号”（R/V Oceanus）科考船的OC468航次，作业采用温盐深采水器系统（CTD-rosette system）完成。本次航次的核心目标为，在深水地平线（Deepwater Horizon）漏油事件发生后立即采集墨西哥湾北部海域的水柱与底栖生物样本。本航次最初由美国国家科学基金会（National Science Foundation, NSF）生物海洋学项目资助，后调整任务方向，用于探究此次漏油事件的生态影响，并为获得NSF快速响应资助的科研人员提供作业平台。科考船于2010年8月21日从密西西比州格尔夫波特港起航，在油井井口附近及井口南侧、西南侧海域布设采样点开展样本采集工作，最终于2010年9月16日返回格尔夫波特港。
