Chemical, physical, profile and underway oceanographic data collected aboard the GORDON GUNTER in the Gulf of Mexico from 2010-07-01 to 2010-07-06 in response to the Deepwater Horizon Oil Spill event (NODC Accession 0069068)

Chemical, physical, profile and underway oceanographic data were collected aboard the GORDON GUNTER in the Gulf of Mexico from 2010-07-01 to 2010-07-06 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 conductivity, current speed - east/west component (U), current speed - north/south component (V), dissolved oxygen, hydrostatic pressure, salinity, sound velocity, temperature and water density. The instruments used to collect these data included ADCP, CTD and oxygen meter along with other physical sampling devices. More specific information about each data set is located in their individual metadata records. The Acoustic Doppler Current Profiler ADCP used sonar to measure and record water current velocities and the distribution of suspended material over a range of depths. Absolute U- and V-component ocean current vectors from the ADCP collected can be used to create detailed maps of the distribution of water currents and suspended materials through the water column along the ship's path. The data from this ADCP is raw and unprocessed. Some of the datasets associated with this instrument are still incomplete and will be published as they become available. 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). 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.

为响应2010年4月20日发生的深水地平线（Deepwater Horizon）原油泄漏事故，由多家政府与企业机构联合组建的地下监测单元（Subsurface Monitoring Unit, SMU），于2010年7月1日至7月6日搭乘戈登·冈特号（GORDON GUNTER）科考船，在墨西哥湾海域采集了化学、物理、剖面及走航海洋学数据。本次采集的数据涵盖电导率、海流东向分量（U）、海流北向分量（V）、溶解氧、静水压力、盐度、声速、水温与海水密度。用于采集上述数据的仪器包括声学多普勒流速剖面仪（Acoustic Doppler Current Profiler, ADCP）、温盐深仪（Conductivity, Temperature, Depth, CTD）、溶氧仪及其他物理采样设备。各数据集的详细信息可查阅其对应的独立元数据记录。声学多普勒流速剖面仪（ADCP）借助声呐测量并记录不同深度范围内的海流流速与悬浮物质分布；通过该设备采集得到的绝对海流U、V分量矢量，可用于绘制沿科考船航线的水柱内海流与悬浮物质分布精细化图谱。该ADCP采集的数据为原始未处理数据，该仪器关联的部分数据集尚未完成，待就绪后将公开发布。本数据集还包含用于实时分析与决策支持的衍生产品，此类产品包括各类图表、地图、绘图文件以及地理信息系统（Geographic Information System, GIS）格式的数据文件。温盐深仪采集的数据已由国家海岸数据开发中心（National Coastal Data Development Center, NCDDC）完成初步质量保障与质控流程。数据管理人员收集了航次级信息，包括数据管理文件、航次报告与航次计划、影像资料、图片及其他各类辅助文档。（国家海洋数据中心（National Oceanographic Data Center, NODC）存档编号：0069068）
