Department for Environment, Food and Rural Affairs (DEFRA) MCZ: Mid St Georges Channel: Multibeam survey msgc_2_2012: Irish Sea (17/03/2012 to 30/03/2012)

Full coverage multibeam survey collecting bathymetry and backscatter to client specifications, namely International Hydrographic Organization (IHO) Order 1a standard, WGS84 latitude and longitude co-ordinates collected by RTG Global Positioning System (RTG-GPS), depths corrected to Chart Datum (CD), crosslines run at 20 times spacing of main lines. Raw and processed data delivered to Centre for Environment, Fisheries and Aquaculture Science, UK (Cefas) complete with georeferenced mosaics and GeoTiffs images. 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测量成果，按照客户指定规范采集水深地形与反向散射数据，符合国际海道测量组织（International Hydrographic Organization, IHO）1a级标准。采用RTG全球定位系统（RTG Global Positioning System, RTG-GPS）采集WGS84经纬度坐标，水深数据已校正至海图基准面（Chart Datum, CD），旁测线的布设间距为主测线的20倍。原始及处理后的数据已交付至英国环境、渔业与水产养殖科学中心（Centre for Environment, Fisheries and Aquaculture Science, UK, Cefas），同步附带地理参考镶嵌图与GeoTIFF图像。本数据集已存档于海洋环境数据与信息网络（Marine Environmental Data and Information Network, MEDIN）数据存档中心（Data Archive Centres, DACs），其中包括英国地质调查局（British Geological Survey, BGS）地质与地球物理数据DAC、海洋物种与栖息地数据档案馆（The Archive for Marine Species and Habitats Data, DASSH）以及英国水道测量局（United Kingdom Hydrographic Office, UKHO）水深数据DAC。含原始数据的完整现场数据包亦可通过向英国地质调查局（BGS）申请获取。
