Sub-bottom chirp data acquired in the Salton Sea, California, between 2006 and 2008

More than 1,000 line-km of sub-bottom chirp data were collected with an Edgetech 0.5-16 kHz subscan system by Scripps Institution of Oceanography between 2006 and 2008 in the Salton Sea, California, with assistance from the U.S. Geological Survey (USGS). Data were subsequently donated by Scripps to the USGS for public release (USGS field activity identifier 2006-603-DD).

2006年至2008年间，斯克里普斯海洋研究所于美国加利福尼亚州索尔顿湖海域，使用Edgetech公司生产的0.5-16 kHz SubScan系统，采集了测线总长超过1000千米的浅地层线性调频声呐数据（sub-bottom chirp data）。本次数据采集工作得到了美国地质调查局（U.S. Geological Survey，缩写USGS）的协助。后续斯克里普斯海洋研究所将该批数据捐赠予美国地质调查局，以供公开发布（美国地质调查局野外活动标识号：2006-603-DD）。
