Bathymetry [2m]--Offshore of Monterey Map Area, California

This part of DS 781 presents data for 2-m and 5-m bathymetry and shaded-relief maps of Offshore of Monterey map area, California. The raster data file is included in "Bathymetry_2m_OffshoreMonterey.zip," which is accessible from http://dx.doi.org/10.5066/F7F47M6T.
The 2-m and 5-m bathymetry and shaded-relief maps of Offshore of Monterey map area, California, was generated from acoustic bathymetry data collected by California State University, Monterey Bay (CSUMB) and by Monterey Bay Aquarium Research Institute (MBARI), as well as from bathymetric lidar data collected by the U.S. Army Corps of Engineers, Joint Airborne Lidar Bathymetry Center of Expertise (JALBTCX). Acoustic mapping was completed between 1998 and 2012 using a combination of 200-kHz/400-kHz Reson 7125, 100-kHz Reson 7111, 240-kHz Reson 8101, and 30-kHz Simrad EM-300 multibeam echosounders, as well as 234-kHz and 468-kHz SWATHplus bathymetric sidescan-sonar systems. Bathymetric lidar mapping was completed between 2009 and 2010 for the California Coastal Mapping Project (CCMP). These mapping missions combined to collect bathymetry data from the shoreline to beyond the limit of California’s State Waters. NOTE: The horizontal datum of this bathymetry data (NAD83) differs from the horizontal datum of other layers in this data release (WGS84).

本部分为DS 781数据集提供加利福尼亚州蒙特雷近海制图区的2米、5米水深地形（bathymetry）及晕渲地形图（shaded-relief maps）数据。栅格数据文件包含于"Bathymetry_2m_OffshoreMonterey.zip"压缩包中，可通过http://dx.doi.org/10.5066/F7F47M6T获取。
加利福尼亚州蒙特雷近海制图区的2米、5米水深地形及晕渲地形图，数据源自加利福尼亚州立大学蒙特雷湾分校（California State University, Monterey Bay, CSUMB）与蒙特雷湾水族馆研究所（Monterey Bay Aquarium Research Institute, MBARI）采集的声学水深测量数据，以及美国陆军工程兵团联合机载激光测水深专家中心（Joint Airborne Lidar Bathymetry Center of Expertise, JALBTCX）获取的测深激光雷达（bathymetric lidar）数据。声学测绘工作于1998年至2012年间开展，所用设备包括200kHz/400kHz Reson 7125、100kHz Reson 7111、240kHz Reson 8101与30kHz Simrad EM-300多波束测深仪，以及234kHz、468kHz的SWATHplus水深侧扫声呐系统。测深激光雷达测绘工作于2009年至2010年间为加利福尼亚海岸测绘项目（California Coastal Mapping Project, CCMP）完成。本次联合测绘任务采集了从海岸线至加州州辖海域边界以外的全部水深数据。注意：本次水深数据的水平基准面为NAD83，与本数据发布中其他图层所用的水平基准面WGS84不一致。
