Department for Environment, Food and Rural Affairs (DEFRA) MCZ: Offshore Brighton: Multibeam, Benthic Sampling and Video survey OBRG_cend0812: Eastern Channel (06/06/2012 to 10/06/2012)

A seabed survey for the purpose of habitat identification and mapping at the Offshore Brighton recommended Marine Conservation Zone (rMCZ) site. Ground-truth sampling by grabs and underwater cameras (video & stills images). Multibeam bathymetry and backscatter collected opportunistically on transit between stations. Broadscale habitat (BSH) and habitat FOCI (Features of Conservation Interest) recorded at time of sampling and included in cruise/survey report. More in-depth interpretation to be made in a Post-Survey Site Report, following integrated assessment of acoustics and outputs from laboratory analysis of benthic samples. 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.本数据集为针对布赖顿近海推荐海洋保护区（recommended Marine Conservation Zone, rMCZ）站点开展的生境识别与制图专项海底调查。调查采用抓斗采样器与水下相机（含视频与静态图像）完成实地验证采样；多波束测深与后向散射数据于各测站间的航行阶段临时采集获取。采样过程中同步记录了宽尺度生境（Broadscale habitat, BSH）与保护关注生境特征（Features of Conservation Interest, FOCI）相关信息，并将其纳入本次航次/调查报告。待完成声学数据集成评估与底栖样品实验室分析结果的综合研判后，将在《调查后站点报告》中开展更为深入的生境解译工作。本项目相关数据已归档至海洋环境数据与信息网络（Marine Environmental Data and Information Network, MEDIN）下属的数据归档中心（Data Archive Centres, DACs），具体包括英国地质调查局（British Geological Survey, 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（The Archive for Marine Species and Habitats Data, DASSH）以及英国水道测量局（United Kingdom Hydrographic Office, UKHO）测深数据归档中心。完整的站点数据集（含原始数据）亦可应相关要求向英国地质调查局申请获取。
