Department for Environment, Food and Rural Affairs (DEFRA) MCZ: East of Celtic Deep: Multibeam, Benthic Sampling and Photo/Video Survey ECLD_cend0312: Western Channel & Celtic Sea (18/02/2012 to 19/02/2012)

Full coverage multibeam survey collecting bathymetry and backscatter to International Hydrographic Organization (IHO) Order 1a standard, WGS84 latitude and longitude co-ordinates collected by Differential Global Positioning System (D-GPS), depths corrected to Chart Datum (CD), Raw and processed data delivered to Centre for Environment, Fisheries and Aquaculture Science, UK (Cefas) complete with georeferenced mosaics and GeoTiffs images. Groundtruth survey collecting sediment samples (using Hamon grab) for infaunal anaysis and PSA and video and still image samples (using combination of camera sledge and drop camera). These data are archived with the Marine Environmental Data and Information Network (MEDIN) Data Archive Centres (DACs) including the British Geological Survey (BGS) DAC for geology and geophysics, The Archive for Marine Species and Habitats Data (DASSH) and the United Kingdom Hydrographic Office (UKHO) bathymetry DAC. The full site data package including raw is also available on request from BGS.本数据集为全覆盖多波束勘测项目，采集水深与海底反向散射数据，符合国际海道测量组织（IHO）1a级标准。勘测采用差分全球定位系统（D-GPS）获取WGS84坐标系下的经纬度坐标，所有水深数据均已校正至海图基准面（CD）。原始与经处理后的全套数据已交付至英国环境、渔业与水产养殖科学中心（Cefas），并附带地理参考镶嵌图与GeoTIFF图像。 本数据集同时包含实地验证勘测内容：采用哈蒙采泥器采集底质样本，用于底内动物分析与颗粒尺寸分析（PSA），并结合摄像雪橇与下放式相机采集视频及静态图像样本。 上述所有数据已存档于海洋环境数据与信息网（MEDIN）旗下的多家数据存档中心（DACs），其中包括负责地质与地球物理数据存档的英国地质调查局（BGS）数据存档中心、海洋物种与栖息地数据档案馆（DASSH），以及英国水道测量局（UKHO）水深数据存档中心。完整的站点数据包（含原始数据）可通过向英国地质调查局（BGS）提出申请获取。
