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.

本部分DS 781提供了加利福尼亚州鸽子角至南蒙特雷湾区域的海侵等高线（transgressive contours）相关数据。该矢量文件收录于"TransgressiveContours_PigeonPointToSouthMontereyBay.zip"压缩包中，可通过http://dx.doi.org/10.5066/F7N29V0Z获取。
作为美国地质调查局（USGS）加利福尼亚州水域填绘项目的组成部分，研究人员依托2009年与2010年采集的地震反射数据（辅以DS 781提供的露头与地质构造资料，对应USGS作业活动编号S-15-10-NC与S-N1-09-MB），生成了鸽子角至南蒙特雷湾段加利福尼亚州管辖水域内海底沉积物厚度的50米网格数据集。该数据集覆盖面积约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。基于该网格数据集，提取得到间隔为5米的海侵等高线。
