Department for Environment, Food and Rural Affairs (DEFRA) MCZ: South West Deeps (West): Multibeam, Benthic Sampling and Video survey SWDW_CEND0613: (08/05/2013 to 28/05/2013)

Ground truthing (GT) survey to provide data which would be used in conjunction with the existing multibeam echosounder (MBES) acoustic data (bathymetry and backscatter) to determine the presence and extent of broad scale habitats (BSH) and Habitat FOCI present within the SWDW rMCZ. A. 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.本研究开展实地验证（Ground Truthing，简称GT）调查，旨在获取可与现有多波束测深声呐（Multibeam Echosounder，简称MBES）声学数据（涵盖水深地形与反向散射数据）协同分析的数据，以判定SWDW rMCZ区域内大尺度生境（Broad Scale Habitats，简称BSH）与生境FOCI（Habitat FOCI）的分布范围与覆盖程度。此类数据已归档于海洋环境数据与信息网络（Marine Environmental Data and Information Network，简称MEDIN）的数据归档中心（Data Archive Centres，简称DACs），具体包括英国地质调查局（British Geological Survey，简称BGS）地质与地球物理数据归档中心、海洋物种与生境数据档案馆（Archive for Marine Species and Habitats Data，简称DASSH），以及英国水道测量局（United Kingdom Hydrographic Office，简称UKHO）水深地形数据归档中心。包含原始数据在内的完整站点数据集，也可通过向BGS提出申请获取。
