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).

DS 781的本章节提供了加利福尼亚州蒙特雷峡谷及周边区域的2米与5米水深（bathymetry）地貌晕渲图（shaded-relief maps）数据。栅格数据文件收录于"BathymetryB_5m_MontereyCanyon.zip"，可通过http://dx.doi.org/10.5066/F7XD0ZQ4获取。这套蒙特雷峡谷及周边区域的2米、5米水深与地貌晕渲图，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。制图工作于1998年至2014年间完成，所用设备包括30-kHz Simrad EM-300、200-kHz/400-kHz Reson 7125多波束测深仪，以及234-kHz和468-kHz SEA SWATHplus水深侧扫声呐系统。本次测绘任务采集了约10米等深线至加州州属水域3海里以外区域的水深数据。注意：本次水深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。
