Late Quaternary Evolution and Stratigraphic Framework Influence on Coastal Systems along the North-Central Gulf of Mexico, USA
… climate change. The stratigraphic framework and antecedent topography directly influence coastal evolution over geologic timescales. This study synthesizes ~2100km of geophysical data, 700+ sediment cores, and 63 radiocarbon dates to regionally map two sequence boundaries, multiple ravinement …

Configuration of the Pleistocene Surface Beneath Cat Island, Mississippi and Implications for Barrier Island Formation and Evolution
… The geometry and composition of local antecedent topography plays a role in barrier formation by providing an elevated base, nucleus for sedimentation and local sediment supply. Investigation of barriers' subsurface geology provides insight into island formation and evolution. …

Spatial variability in washover deposits : Hurricane Ike and the Texas coast
… the volume change, and the relationship with the antecedent topography all present changes that generally mirrors the alongshore decay of Hurricane Ike’s energy, represented by the storm surge and waves. These are put in context using the ratio, called here r, that is the maximum surge height in …

Late Quaternary variability in coastal changes along the Texas Gulf coast
… internal (autogenic) basinal mechanisms such as antecedent topography, regional subsidence, wave climate, offshore profile, and anthropogenic effects. The central Texas coast is characterized by stable barriers whereas the upper and south Texas coast is dominated by transgressive barriers. These …

Seismic-stratigraphic analysis of shelf-margin delta/slope fan and basin floor fan on high-latitude and middle-latitude margins (Ross Sea, Weddell Sea and Alabama/West Florida shelf): Paleoclimatic and eustatic implications
… of the upper slope. Therefore, other factors (antecedent topography, salt tectonics and growth faulting) are deemed to be more important initiators of upper-slope canyon formation on the middle-latitude margin.
