Seismic Project Information EW9513
Pacific-Australia-Antarctic Plate Circuit

This R/V Ewing survey explored the Southeastern Indian Ocean and southern Tasman Sea region, recording 4-channel data. Part of a collaborative project, there was a companion cruise on board the R/V Palmer (NBP9702) north of the Ross Sea embayment. The objective was to obtain data to test the hypothesis that the Antarctic side of the ridge acted as a separate plate, attached to Marie Byrd Land, and that there was motion between East and West Antarctica between anomalies 24 and 13 time.

MSDC currently has shot (field) data on-line. Trace 3 was stripped from the original 4-channel data to produce seismic images and associated strip files.
