Chemical, physical, profile and laboratory analysis oceanographic data collected aboard the Ferrel in the Gulf of Mexico from 2010-08-18 to 2010-08-23 in response to the Deepwater Horizon Oil Spill event (NCEI Accession 0069065)

Chemical, physical, profile and laboratory analysis oceanographic data were collected aboard the Ferrel in the Gulf of Mexico from 2010-08-18 to 2010-08-23 in response to the Deepwater Horizon Oil Spill event on April 20, 2010, by the Subsurface Monitoring Unit (SMU), which consisted of multiple government and corporate agencies. These data include CDOM fluorescence, Semivolatile Organic Compounds, Total Petroleum Hydrocarbons (TPH), Volatile Organic Compounds, conductivity, dissolved oxygen, hydrostatic pressure, salinity, sound velocity, temperature and water density. The instruments used to collect these data included CTD, bottle, fluorometer and oxygen meter along with other physical sampling devices. More specific information about each data set is located in their individual metadata records. This data set also contains products created for use in real time analysis and decision support. These products may include charts, graphs, maps, plots, and GIS formatted data files. The CTD data underwent preliminary quality assurance and control procedures at the National Coastal Data Development Center (NCDDC). The analytical chemistry data are provisional and provide results of onshore laboratory analysis of water and sediment samples. Cruise level information consisting of data management documents, cruise reports and plans, videos and pictures, and other miscellaneous documentation were gathered by the data managers.

本数据集为海洋化学、物理、剖面及实验室分析类海洋学数据，由地下监测单元（Subsurface Monitoring Unit, SMU）于2010年8月18日至2010年8月23日搭载Ferrel号船在墨西哥湾采集，以响应2010年4月20日发生的深水地平线漏油事件。该单元由多家政府与企业机构联合组成。
本次采集的数据涵盖有色溶解有机物（CDOM）荧光、半挥发性有机物、总石油烃（TPH）、挥发性有机物、电导率、溶解氧、静水压、盐度、声速、温度及海水密度。数据采集所用仪器包括CTD、采水器、荧光计、溶氧仪及其他物理采样设备。
各数据集的详细说明可查阅其对应的独立元数据记录。本数据集还包含用于实时分析与决策支持的衍生产品，包括各类图表、图形、地图、绘图结果及地理信息系统（GIS）格式数据文件。
CTD数据已在美国国家海岸数据开发中心（National Coastal Data Development Center, NCDDC）完成初步质量保证与质量控制流程。分析化学数据为暂定性数据，提供了水体与沉积物样品的陆上实验室分析结果。
航次层级的相关资料由数据管理人员汇总收集，涵盖数据管理文档、航次报告与航次计划、视频、图片及其他各类杂项文档。(NODC Accession 0069065)
