Abstract
During the RVIB Nathaniel B. Palmer 1994–01 and 1995–01 cruises, approximately 7141 km of 50 in3 airgun seismic profiles and 12,150 km of 3.5 kHz trackline data were collected from the Ross Sea continental shelf. Ross Sea is a broad embayment, approximately 1500 km wide and 900 km long, on the Antarctic coast (Fig. 1). Water depths range from less than 300 m to greater than 1200 m and average in excess of 500 m. Bathymetry is dominated by a series of roughly northeast-southwest ridges and troughs. The continental shelf is foredeepened; the inner shelf is deeper than the outer shelf due to a combination of enhanced glacial scour and isostatic loading. Repeated expansion of the East and West Antarctic ice sheets is interpreted to have modified the continental shelf. The records of the most recent glacial expansions are preserved in the surficial features and sedimentary deposits of the Ross Sea floor.
