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DS 781数据集的本部分提供了加利福尼亚州蒙特雷峡谷及周边区域的2米、5米分辨率水深测绘（bathymetry）数据与晕渲地貌图（shaded-relief map）数据。栅格数据文件包含于"BathymetryB_5m_MontereyCanyon.zip"中，可通过http://dx.doi.org/10.5066/F7XD0ZQ4获取。 加利福尼亚州蒙特雷峡谷及周边区域的2米、5米分辨率水深测绘与晕渲地貌图数据，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）采集的水深测绘数据生成。测绘工作于1998年至2014年间完成，期间采用了30 kHz Simrad EM-300、200 kHz/400 kHz Reson 7125多波束测深仪，以及234 kHz与468 kHz SEA SWATHplus侧扫声呐测深系统开展作业。本次测绘任务采集了约10米等深线至加州领海3海里以外区域的水深测绘数据。注意：本次水深测绘数据的水平基准面为NAD83，与本数据集中其他图层的水平基准面WGS84不一致。
