Bathymetry from multibeam data collected on the RV Heincke, cruises HE-324 and HE-349, North Sea, Helgoland (Germany)

Mosaicked multibeam-derived bathymetry from Simrad EM710 on board RV Heincke collected during Spring 2010 (HE- 324) and 2011 (HE-349). Water depths range from 20 to 50 meters. The range of opening angles of the EM710 multibeam varies between 50 and 65 degrees. EM710 data were used in conjunction with an OCTANS motion sensor, ship’s DGPS and Sound Velocity Profiles (SVP). CRS information: WGS 84 / UTM zone 32N.

本数据集为2010年春季（航次HE-324）与2011年（航次HE-349）期间，在考察船海因克号（RV Heincke）上搭载西姆拉德EM710（Simrad EM710）多波束测深系统采集并经拼接处理的多波束测深数据。该数据集覆盖的水深范围为20至50米，EM710多波束系统的开角范围为50至65度。数据采集过程中同步配套使用了OCTANS运动传感器、船载差分全球定位系统（Differential GPS，DGPS）以及声速剖面（Sound Velocity Profiles，SVP）。本数据集采用的坐标参考系统为WGS 84 / UTM 32N分带。
