The SEPA project is a deployment of broadband PASSCAL instruments
in Chilean Patagonia, the South Shetland Islands, and the Antarctic Peninsula.
It is a joint project involving Washington University,
Universidad de Chile, and Bristol University (UK), and is
funded by the U.S. Antarctic Program (NSF - Office of Polar Programs) and
the Instituto Antartico Chileno (INACH). 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 have now been removed, but one Patagonia station and three Antarctic stations continue to operate.
This site contains a
brief description of the project, station location maps, and a gallery
of photos, including typical station layout, as well as plenty of penguins
and seals.
