BathymetryB [5m]--Monterey Canyon and Vicinity, California

This part of DS 781 presents data for 2-m and 5-m bathymetry and shaded-relief maps of Monterey Canyon and Vicinity, California. The raster data file is included in "BathymetryB_5m_MontereyCanyon.zip," which is accessible from http://dx.doi.org/10.5066/F7XD0ZQ4. The 2-m and 5-m bathymetry and shaded-relief maps of Monterey Canyon and Vicinity, California, were generated from bathymetry data collected by the U.S. Geological Survey (USGS), by Monterey Bay Aquarium Research Institute (MBARI), and by California State University, Monterey Bay (CSUMB). Mapping was completed between 1998 and 2014 using a combination of 30-kHz Simrad EM-300 and 200-kHz/400-kHz Reson 7125 multibeam echosounders, as well as 234-kHz and 468-kHz SEA SWATHplus bathymetric sidescan-sonar systems. The mapping missions collected bathymetry data from about the 10-m isobath to beyond the 3-nautical-mile limit of Californiaís State Waters. NOTE: The horizontal datum of this bathymetry data (NAD83) differs from the horizontal datum of other layers in this data release (WGS84).本数据集（DS 781）包含加利福尼亚州蒙特雷峡谷及周边区域的2米、5米分辨率水深（bathymetry）数据与晕渲地形图。该栅格数据文件已打包至"BathymetryB_5m_MontereyCanyon.zip"，可通过链接http://dx.doi.org/10.5066/F7XD0ZQ4获取。 本次加利福尼亚州蒙特雷峡谷及周边区域的2米、5米分辨率水深数据与晕渲地形图，由美国地质调查局（U.S. Geological Survey, USGS）、蒙特雷湾水族馆研究所（Monterey Bay Aquarium Research Institute, MBARI）以及加州州立大学蒙特雷湾分校（California State University, Monterey Bay, CSUMB）采集的水深数据制作生成。本次测绘工作于1998年至2014年间完成，采用了30kHz Simrad EM-300、200kHz/400kHz Reson 7125多波束测深仪，以及234kHz与468kHz SEA SWATHplus水深侧扫声呐系统组合方案。本次测绘任务采集的水深数据覆盖范围约从10米等深线至加州领海3海里界限以外区域。注意：本次水深数据采用的水平基准面为NAD83，与本数据集中其他图层所使用的WGS84水平基准面不一致。
