BathymetryA Hillshade [USGS]--Offshore Aptos, California

This part of DS 781 presents data for the bathymetry and shaded-relief maps of Offshore of Aptos map area, California. Bathymetry data are provided as two separate grids depending on mapping agency and processing method. The raster data files are included in "BathymetryAHS_USGS_OffshoreAptos.zip," which is accessible from http://dx.doi.org/10.5066/F7K35RQB.
The bathymetry and shaded-relief maps of Offshore Aptos, California, were generated from bathymetry data collected by the U.S. Geological Survey (USGS) and by California State University, Monterey Bay (CSUMB). Mapping was completed between 2006 and 2009 using a combination of a 244-kHz Reson 8101 multibeam echosounder and a 234-kHz SEA SWATHplus bathymetric sidescan-sonar system. The mapping missions collected bathymetry data from about the 10-m isobath to beyond the 3-nautical-mile limit of California’s State Waters.

本数据集为DS 781的组成部分，涵盖加利福尼亚州阿普托斯近海（Offshore of Aptos）制图区域的水深与阴影晕渲地图数据。依据制图机构与处理方法的不同，水深数据分为两个独立栅格网格。相关栅格数据文件存储于"BathymetryAHS_USGS_OffshoreAptos.zip"压缩包中，可通过http://dx.doi.org/10.5066/F7K35RQB获取。

加利福尼亚州阿普托斯近海的水深与阴影晕渲地图，基于美国地质调查局（U.S. Geological Survey, USGS）与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2006年至2009年间完成，采用244kHz Reson 8101多波束测深仪与234kHz SEA SWATHplus水深侧扫声呐系统的组合方案。本次测绘任务采集了从约10米等深线至加州州属海域3海里边界以外区域的水深数据。
