Marine mammal observations and mitigations associated with USGS seismic surveys in the southern California Bight in 1998
Calambokidis,J., L. Schlender, and J. Quan. 1998. Marine mammal observations and mitigations associated with USGS seismic surveys in the southern California Bight in 1998. Report to U.S. Geological Survey, Menlo Park, CA. Cascadia Research, 218½ W Fourth Ave., Olympia, WA
From 9 to 22 August 1998, the U.S. Geological Survey conducted seismic surveys in the Pacific Ocean just off Los Angeles to investigate earthquake hazards. Details on the purposes and specifications of the equipment used are described below. As a part of this project, Cascadia Research was contracted by the USGS to monitor marine mammals from the survey platform and provide mitigation on impacts on marine mammals by requesting shutdown of the sound sources when marine mammals were close to the operations. We report here the results of this marine mammal mitigation and monitoring program conducted in conjunction with the USGS Los Angeles surveys.
