Raw sidescan sonar data from Inner Dowsing, Race Bank and North Ridge cSAC, and Haisborough, Hammond and Winterton cSAC

Raw sidescan sonar data from Inner Dowsing, Race Bank and North Ridge cSAC, and Haisborough, Hammond and Winterton cSAC (CEND 11/11). This survey, carried out on the Cefas Endeavour research vessel, used acoustic data and ground truthing to assess location, extent and condition of the Annex 1 habitats "Sandbanks slightly covered by sea water all the time" and "Reefs" in the Inner Dowsing, Race Bank and North Ridge cSAC and the Haisborough, Hammond and Winterton cSAC.原始侧扫声呐（sidescan sonar）数据取自Inner Dowsing、Race Bank及North Ridge海洋特别保护区（cSAC）与Haisborough、Hammond及Winterton海洋特别保护区（cSAC），数据编号为CEND 11/11。本次调查由Cefas Endeavour号科研船开展，通过声学数据与实地验证（ground truthing）技术，对上述两处保护区内附录1所列生境——"持续被海水轻度覆盖的沙岸"与"礁体"——的位置、分布范围及健康状况进行评估。
