| Description: | SPaSE projectThe SPaSE project was a two year deployment of 12 broadband PASSCAL instruments in Fiji, Tonga, and Niue Island. Earthquakes recorded by SPaSE stations are used to study the structure of the subducting slab using phases converted at the upper slab interface, dispersion of phases traveling up the slab, and comparison of travel times between phases traveling inside and outside of the slab.LABATTS projectLABATTS was a 3-month deployment of 30 Ocean Bottom Seismographs (OBS) in the Lau backarc and Tonga forarc during late 1994. The OBS survey took place during the Southwest Pacific Seismic Experiment (SPaSE), a 2 year deployment of 12 broadband seismographs on the islands of the Tonga-Fiji region. Scripps Institute of Oceanography was the lead in the project LABATTS.Mariana projectThe Mariana project was a large-scale multidisciplinary endeavor to image the Mariana subduction zone. It utilized multi-channel seismic reflection to image shallow geological features, controlled-source wide-angle reflection/refraction to constrain crustal structure, and passive broadband land and ocean bottom seismographs (OBS) to image the upper mantle. Washington University focussed on the passive aspect of the project, which consists of an 18-month land deployment of 20 stations and a 12-month deployment of 70 OBS.SEPA projectThe 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. |
