Abstract
Using existing and new seismic reflection data, new and updated correlations of late Oligocene-early
Miocene RSS-2 strata were made between the southern parts of Ross Sea basins. Previous studies documented
Cretaceous extension across much of Ross Sea. We interpret that Cenozoic extension also occurred across Ross Sea.
Subsidence during and following this extension deepened existing basins and may have initiated basins in the west,
subsiding ridges between basins below sea level during the late Oligocene. Pre-Oligocene strata record cessation of L.
Cretaceous extension in easternmost Ross Sea. Successively younger Cenozoic extension occurred from east to west
across the rest of Ross Sea.
