Bathymetry--Offshore Scott Creek, California

This part of DS 781 presents data for the bathymetry and shaded-relief maps of Offshore Scott Creek, California. The raster data file is included in "Bathymetry_OffshoreScottCreek.zip", which is accessible from http://dx.doi.org/10.5066/F7CJ8BJW. The bathymetry and shaded-relief maps of Offshore Scott Creek, California, were generated from bathymetry data collected by California State University, Monterey Bay (CSUMB), by Fugro Pelagos, and by the U.S. Geological Survey (USGS). Mapping was completed between 2006 and 2009, using a combination of 400-kHz Reson 7125 and 244-kHz Reson 8101 multibeam echosounders, as well as a 234-kHz SWATHplus bathymetric sidescan-sonar system. These mapping missions combined to collect bathymetry from about the 10-m isobath to beyond the 3-nautical-mile limit of California’s State Waters. NOTE: The horizontal datum of this bathymetry data (NAD83) differs from the horizontal datum of other layers in this SIM (WGS84). Some bathymetry grids within this map area were projected horizontally from WGS84 to NAD83 using ESRI tools to be more consistent with the vertical reference of the North American Vertical Datum of 1988 (NAVD88).本数据集DS 781的此部分，提供了加利福尼亚州斯科特溪近海（Offshore Scott Creek）的水深测量（bathymetry）与阴影晕渲地形图（shaded-relief maps）相关数据。栅格数据文件收录于"Bathymetry_OffshoreScottCreek.zip"压缩包中，可通过链接http://dx.doi.org/10.5066/F7CJ8BJW获取。 加利福尼亚州斯科特溪近海的水深测量与阴影晕渲地形图，由加州州立大学蒙特利湾分校（California State University, Monterey Bay, CSUMB）、富格罗佩拉戈斯（Fugro Pelagos）以及美国地质调查局（U.S. Geological Survey, USGS）采集的水深数据生成。制图工作于2006年至2009年间完成，综合使用了400kHz Reson 7125与244kHz Reson 8101多波束测深仪，以及234kHz SWATHplus水深侧扫声呐系统。本次联合测绘任务采集的水深数据覆盖范围约从10米等深线延伸至超出加利福尼亚州领海3海里的海域。 请注意：本次水深数据的水平基准面为NAD83，与本SIM中其他图层的水平基准面WGS84存在差异。本制图区域内的部分水深栅格，已借助ESRI工具从WGS84水平投影至NAD83，以更匹配1988年北美垂直基准面（North American Vertical Datum of 1988, NAVD88）的垂直参考基准。
