Sediment thickness grid of the deep-sea basins offshore of Washington, Oregon, and California (cowthkg.tif) based on data collected in 1984

Cowthkg.tif is a 1000-m resolution grid of sediment thickness derived from contours (cowiso.shp, also in this data set) from 1:1,000,000-scale Map Showing Sediment Isopachs in the Deep-sea Basins of the Pacific Continental Margin, Strait of Juan de Fuca to Point Loma, California (Gardner and others, 1992, 1993a, 1993b). The maximum sediment thickness in this region is 2342 m with a mean value of 359 m.Cowthkg.tif为分辨率1000米的沉积物厚度网格数据，其数据提取自本数据集收录的矢量文件cowiso.shp，该矢量文件的原始制图依据为1:100万比例尺的《太平洋大陆缘深海盆地沉积物等厚线图（胡安·德富卡海峡至加利福尼亚州洛马角）》，该图件由Gardner等人于1992年、1993a年、1993b年发布。本区域内沉积物最大厚度为2342米，平均厚度为359米。
