Eastern IFCA (EIFCA) Geophysical Survey 2014_RP2014D The Well habitat mapping: (07/Jul/2014 to 08/Aug/2014)

Eastern Inshore Fisheries and Conservation Authority (EIFCA) sidescan sonar survey to characterise the seabed of areas of The Wash, in particular to identify areas indicative of Cobble & Boulder habitat, and of Sabellaria spinulosa. The data is used to inform EIFCA's monitoring within the Wash and North Norfolk Coast Special Area of Conservation. The intention is that the surveys will be repeated at intervals. The survey took place from 7/7/2014 to 8/8/2014 on board the RV Three Counties. Sidescan sonar data were collected using an Edgetech 4200-P Sidescan sonar System. These data are archived at the BGS MEDIN Data Archive Centre (DAC) for Geology and Geophysics. Technical details of the survey are contained in EIFCA Research Report 2014.本数据集为东部近岸渔业与保护管理局（Eastern Inshore Fisheries and Conservation Authority, EIFCA）开展的侧扫声呐（sidescan sonar）勘测项目，旨在对英国沃什湾（The Wash）海域的海底特征进行表征，重点识别具备砾石与巨砾生境（Cobble & Boulder habitat）以及刺沙蚕（Sabellaria spinulosa）分布特征的区域。该数据用于支撑EIFCA在沃什湾及北诺福克海岸特殊保育区（Special Area of Conservation）的监测工作。项目计划定期重复开展此类勘测作业。本次勘测于2014年7月7日至2014年8月8日在研究船（Research Vessel, RV）“三郡号”（Three Counties）上实施，采用Edgetech 4200-P型侧扫声呐系统（Edgetech 4200-P Sidescan sonar System）采集侧扫声呐数据。相关数据已存档于英国地质调查局（British Geological Survey, BGS）海洋环境数据网络（Marine Environmental Data Network, MEDIN）下属的地质与地球物理数据存档中心（Data Archive Centre, DAC）。本次勘测的技术细节详见EIFCA 2014年研究报告。
