BathymetryA [2m]--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 "BathymetryA_2m_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的此部分提供了加利福尼亚州蒙特雷峡谷及其周边区域2米与5米分辨率的水深（bathymetry）数据及晕渲地形图（shaded-relief maps）。相关栅格数据文件收录于"BathymetryA_2m_MontereyCanyon.zip"，可通过http://dx.doi.org/10.5066/F7XD0ZQ4获取。
这套蒙特雷峡谷及其周边区域的2米、5米水深及晕渲地形图数据，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）采集的水深数据生成。测绘工作于1998年至2014年间完成，所用设备包括30kHz的Simrad EM-300多波束测深仪（multibeam echosounders）、200kHz/400kHz的Reson 7125多波束测深仪，以及234kHz与468kHz的SEA SWATHplus水深侧扫声呐（sidescan-sonar）系统。本次测绘任务采集了从约10米等深线（isobath）至超出加利福尼亚州海域3海里界限范围内的水深数据。注意：本次水深数据的水平基准面（horizontal datum）为NAD83，与本数据发布中其他图层的水平基准面WGS84存在差异。
