Seismic Experiment in Patagonia and Antarctica

Project Description

The SEPA project was a deployment of broadband PASSCAL instruments in
Chilean Patagonia, the South Shetland Islands, and the Antarctic
Peninsula. The initial ten broadband seismographs were deployed during
January and February, 1997. Additional sites were added in 1998 and
1999. A complementary 6 month deployment of ocean bottom seismographs
in the Bransfield Strait and South Shetland Islands (BSOBS) took place
in early 1999. Most of the seismometers were removed in December 1999,
but one Patagonia station and three Antarctic stations continued to
operate until November 2001. The purpose of SEPA is to study the
tectonics and structure of the region.
