CCALBATC - bathymetric contours for the central California region between Point Arena and Point Sur.

CCALBATC consists of bathymetric contours at 10-m and 50-m intervals for the area offshore of central California between Point Arena to the north and Point Sur to the south. The lines were digitized from 1:250,000-scale NOAA charts.

This is one of a collection of digital files of a geographic information system of spatially referenced data related to the USGS Coastal and Marine Geology Program "Monterey Bay National Marine Sanctuary Project" http://walrus.wr.usgs.gov/mbms. The data were collected and analyzed between 1994 and 2000.

CCALBATC 数据集包含北起阿雷纳角（Point Arena）、南至苏尔角（Point Sur）的加利福尼亚中部近岸海域的水深等深线，等深线间隔分别为10米与50米。该等深线数据系从比例尺为1:250000的美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）海图数字化而来。
本数据集为美国地质调查局（United States Geological Survey，USGS）海岸与海洋地质项目“蒙特雷湾国家海洋保护区项目”的地理信息系统空间参考数据数字文件集合之一，相关资源访问链接为 http://walrus.wr.usgs.gov/mbms。该数据的采集与分析工作于1994年至2000年间完成。
