Bathymetry--Offshore San Gregorio, California

This part of SIM 3306 presents data for the bathymetry and shaded-relief maps (see sheet 1 and 2, SIM 3306) of the Offshore of San Gregorio map area, California. The raster data file is included in "Bathymetry_OffshoreSanGregorio.zip," which is accessible from http://pubs.usgs.gov/ds/781/OffshoreSanGregorio/data_catalog_OffshoreSanGregorio.html.
The bathymetry and shaded-relief maps of Offshore San Gregorio, California, were generated from bathymetry data collected by Fugro Pelagos and by California State University, Monterey Bay (CSUMB). Mapping was completed in 2006 and 2007, using a combination of 400-kHz Reson 7125 and 244-kHz Reson 8101 multibeam echosounders. These mapping missions combined to collect bathymetry (sheets 1, 2) from about the 10-m isobath to beyond the 3-nautical-mile limit of CaliforniaÕs State Waters.

本数据集为SIM 3306的组成部分，包含加利福尼亚州圣格雷戈里奥近海制图区域的水深测量（bathymetry）与晕渲地形图（shaded-relief maps）相关数据（详见SIM 3306的第1、2幅图）。其栅格数据文件收录于"Bathymetry_OffshoreSanGregorio.zip"压缩包中，可通过链接http://pubs.usgs.gov/ds/781/OffshoreSanGregorio/data_catalog_OffshoreSanGregorio.html获取。加利福尼亚州圣格雷戈里奥近海的水深测量与晕渲地形图，由Fugro Pelagos公司与加州州立大学蒙特雷湾分校（California State University, Monterey Bay, CSUMB）采集的水深数据生成。制图工作于2006年至2007年间完成，采用400kHz Reson 7125型与244kHz Reson 8101型多波束测深仪（multibeam echosounders）组合实施测绘。本次联合测绘任务共采集了约10米等深线（isobath）至加利福尼亚州领海3海里界限以外区域的水深数据，对应第1、2幅图。
