This was a joint UT and Lamont-Doherty Earth Observatory program collecting a series of MCS lines in the Bransfield Strait, across the South Shetland Trench and farther south along the Antarctic margin. UTIG was responsible for the Bransfield Strait and South Shetland Trench data. Additional lines collected farther south along the margin were the responsibility of Lamont-Doherty Earth Observatory. The goals were to increase understanding of the following processes: Andean-type orogenesis, continental lithosphere extension in a convergent continental margin setting, ridge crest subduction, and interaction of large- offset fracture zones with convergent margins, including the uplift of subduction complexes. Funded by NSF grants OCE89-17332 and OCE89-16436. ...
