Sedimentary processes in the Wilkes Land margin: a record of the Cenozoic East Antarctic Ice Sheet evolution

Glacial Intensification During the Neogene: A Review of Seismic Stratigraphic Evidence from the Ross Sea, Antarctica, Continental Shelf

“…A similar stratal pattern is noted from the Antarctic Peninsula Pacific margin (Bart and Anderson, 1995;Bart and Iwai, 2012), Prydz Bay margin (Cooper and O'Brien, 2004;O'Brien et al, 2007), and Wilkes Land (De Santis et al, 2003;Donda et al, 2007). The overall reduction in sediment production and delivery to the margin is taken by some to represent a shift to significantly drier climatic conditions (De Santis et al, 2003), coincident with the onset of Northern…”

The relationship between ice sheets and submarine mass movements in the Nordic Seas during the Quaternary

“…Other extensive channel/submarine canyon and related submarine fan systems have been found on the Wilkes Land Margin (130 -145 o E) and Queen Maud Land (12 -18 o W) (Escutia et al, 2000;Busetti et al, 2003;De Santis et al, 2003;Ó Cofaigh et al, 2003). The presence and morphology of these systems are thought to be the result of multiple factors and reflect the dynamic evolution of the Antarctic Ice Sheet with changing climate in this sector (Donda et al, 2007). During the Early -Late Miocene (23.03 -5.333 Ma), the meltwater derived from a highly dynamic temperate Antarctic Ice Sheet delivered large amounts of sediment to the shelf edge.…”

“…During the Early -Late Miocene (23.03 -5.333 Ma), the meltwater derived from a highly dynamic temperate Antarctic Ice Sheet delivered large amounts of sediment to the shelf edge. The high sedimentation rate led to the triggering of submarine mass movements (probably turbidity currents) which led in turn to the development of high-relief channel-levee complexes (Donda et al, 2007). Since the end of the Miocene, climatic deterioration has led to a less dynamic ice sheet (Rebesco and Camerlenghi, 2008).…”

Crustal structure of the Transantarctic Mountains near the Ross Sea from ambient seismic noise tomography

“…Improving our knowledge of crustal seismic velocities allows for better determination of crustal thicknesses and is important for constraining geological and geodynamical models. Additionally, better knowledge of shallow crustal structure, in particular the location of sediment, may contribute to advancing our understanding of glacial movement and how it is influenced by the subglacial geology [ Anandakrishnan et al , 1998; Anandakrishnan and Winberry , 2004; Bell et al , 1998; DeConto and Pollard , 2003; Donda et al , 2007; Escutia et al , 2005]. …”
