Transgressive Contours--Pigeon Point to South Monterey Bay, California

This part of DS 781 presents data for the transgressive contours for the Pigeon Point to South Monterey Bay, California, region. The vector file is included in "TransgressiveContours_PigeonPointToSouthMontereyBay.zip," which is accessible from http://dx.doi.org/10.5066/F7N29V0Z
As part of the USGS's California State Waters Mapping Project, a 50-m grid of sediment thickness for the seafloor within the limit of California’s State Waters between Pigeon Point and Southern Monterey Bay was generated from seismic-reflection data collected in 2009 and 2010 (USGS activities (S-15-10-NC and S-N1-09-MB) supplemented with outcrop and geologic structure from DS 781. The resulting grid covers an area of approximately 850 sq km. The depth to the transgressive surface of the Last Glacial Maximum ranges between 1.5 and 144 meters. Contours at 5-meter intervals were derived from this grid.

本数据集（DS 781的此部分）提供了加利福尼亚州鸽子角至南蒙特雷湾区域的海侵面等高线（transgressive contours）数据。矢量文件已打包至"TransgressiveContours_PigeonPointToSouthMontereyBay.zip"压缩包，可通过链接 http://dx.doi.org/10.5066/F7N29V0Z 获取。
作为美国地质调查局（USGS）加利福尼亚州水域测绘项目的一部分，研究人员基于2009至2010年采集的地震反射数据（对应USGS活动编号S-15-10-NC与S-N1-09-MB），并辅以DS 781中的露头与地质构造资料，生成了覆盖鸽子角至南蒙特雷湾范围内加利福尼亚州州属水域界限内海底沉积物厚度的50米分辨率网格数据。该网格数据覆盖面积约850平方千米。末次冰盛期（Last Glacial Maximum）海侵面的埋藏深度介于1.5米至144米之间。基于该网格数据，以5米为间隔生成了对应等高线。
