TGS’ Seismic Survey Uses 160/180 dB and PAM in Chukchi

TGS plans to conduct a two-dimensional (2D) marine seismic survey in the Chukchi Sea during the 2013 open-water season using a 3,280 cubic inches (in3) towed airgun array.  TGS has submitted a marine mammal monitoring and mitigation plan to the U.S. National Marine Fisheries Service and to the U.S. Fish and Wildlife Service to supplement TGS’s Incidental Harassment Authorization and Letter of Authorization applications for the incidental taking of marine mammals in conjunction with this 2D seismic program.

TGS’ plan continues to use the historical acoustic criteria of 160 and 180 dB.  TSG’s plan also incorporates passive acoustic monitoring.
