Salsipuedes-Punta Morro, Baja California, Mexico 2014

This airborne LiDAR dataset collected by NCALM, covers two sites. Site one is a coastal strip (4.5 x 0.4 km) of Salsipuedes Bay, in Baja California, Mexico. It is centered on km 93 of the Ensenada-Tijuana Scenic Highway 1D traversing sea cliffs with steep slopes, cutting exhumed marine sediments of the Rosario formation that are capped in part by the basaltic Rosarito Beach formation. On the night of December 27, 2013, a 220m long segment of the highway, at km 93, started to slide down towards the ocean. The movement continued for several hours until it stabilized the following day after, having displaced a volume close to 300 x 10³ m³ of sandstone 35m down and 25m towards the Pacific Ocean. It took almost a year to repair this massive landslide and reestablish traffic through the main gateway to the Baja California Peninsula. This dataset was collected 186 days after the landslide when reconstruction was already taking place. Site two is Punta Morro, where Ensenada's science cluster is located, hosting CICESE, UNAM and UABC campuses.<p><br>Publications associated with this dataset can be found at <a href="http://calm.geo.berkeley.edu/ncalm/dtc.html" target="_blank">NCALM's Data Tracking Center</a></p>

本由 NCALM 收集的机载激光雷达数据集涵盖了两个地点。第一个地点位于墨西哥下加利福尼亚州萨利斯皮德斯湾的沿海地带（4.5 x 0.4 公里），该地带以恩塞纳达至蒂华纳景观高速公路 1D 的第 93 公里为中心，穿越陡峭的海崖，切割出露的罗萨里奥地层沉积物，部分由玄武岩构成的罗萨里托海滩地层所覆盖。2013 年 12 月 27 日夜间，高速公路第 93 公里处 220 米长的路段开始向海洋滑动，持续数小时直至次日稳定，移动过程中推移了近 300 x 10³ m³ 的砂岩，其中 35 米向太平洋方向移动，25 米向下海移动。修复这场巨大的滑坡并恢复通过下加利福尼亚半岛主要通道的交通几乎花费了一整年的时间。该数据集是在滑坡发生 186 天后收集的，此时重建工作已开始。第二个地点是莫罗角，这里是恩塞纳达的科学集群所在地，拥有 CICESE、UNAM 和 UABC 的校区。<p><br>与该数据集相关的出版物可查阅于 <a href="http://calm.geo.berkeley.edu/ncalm/dtc.html" target="_blank">NCALM 数据追踪中心</a>。</p>
