Holocene sea-level history and the evolution of Sabine Lake and Calcasieu Lake; east Texas and west Louisiana, USA and the glacial retreat history of Maxwell Bay, South Shetland Islands, Antarctica: Implications for ice cap thickness, retreat, and climate change
The history of relative sea-level rise along the northern Gulf of Mexico must be constrained in order to determine the relative effects of eustatic sea-level rise, subsidence, antecedent topography, and sediment supply variations on fluvial--bay-shoreline sedimentary systems. This study adds importa...

The history of relative sea-level rise along the northern Gulf of Mexico must be constrained in order to determine the relative effects of eustatic sea-level rise, subsidence, antecedent topography, and sediment supply variations on fluvial--bay-shoreline sedimentary systems. This study adds important additional sea-level indicators for the past 10 kyrs in addition to compiling the extensive pre-existing data from the literature. The northern Gulf of Mexico data from the modern shoreline is compared western and eastern Gulf of Mexico datasets to determine the relative difference in subsidence rates over the past 4 kyrs. Subsidence differences are negligible. Furthermore, quantification of the antecedent topography provides a means to account for its effects on sedimentary architecture and the evolution of the Sabine and Calcasieu river-bay systems. The record of eustasy potentially indicates 3 to 4 meter-scale rapid rise intervals during the early Holocene. Subsequent to 7.5 ka, the progradation and retrogradation of the sedimentary systems must be attributed to sediment supply variations (climate change). From 7.5 ka to ∼3 ka, the east Texas, west Louisiana climate oscillated between sub-humid to sub-arid to produce greater than modern sediment flux manifested as deltaic deposits in the modern estuaries.
