Abstract Paleoshorelines serve as measures of ancient sea level and ice volume but are affected by solid Earth deformation including processes such glacial isostatic adjustment (GIA) mantle dynamic topography (DT). The early Pliocene Epoch is an important target for sea‐level reconstructions it contains information about the stability sheets during a climate warmer than today. Along southeastern passive margin Argentina, three paleoshorelines date to times (4.8–5.5 Ma), their variable...
Geological indicators of past relative sea level changes are fundamental to reconstruct the extent former ice sheet during interglacials, which considered analogs for future climate conditions.Four dating from Holocene Pliocene, have left sea-level imprints in proximity coastal town Camarones Central Patagonia, Argentina.Sea-level index points were preserved as beach ridges deposited by storm waves above modern level.We used highly accurate survey techniques measure elevation these...
The land surface beneath the Greenland and Antarctic Ice Sheets is isostatically suppressed by mass of overlying ice. Accurate computation elevation in absence ice important when considering, for example, regional geodynamics, geomorphology, sheet behaviour. Here, we use contemporary compilations thickness lithospheric effective elastic to calculate fully re-equilibrated isostatic response solid Earth complete removal Sheets. We an plate flexure model compute unloading modern loads, a...

Abstract. Global mean sea level during the mid-Pliocene Epoch (~3 Ma), when CO2 and temperatures were above present levels, was notably higher than today due to reduced global ice sheet coverage. Nevertheless, extent which sheets responded Pliocene warmth remains in question, owing high levels of uncertainty proxy-based sea-level reconstructions as well solid Earth dynamic models that have been used evaluate a limited number data constraints. Here, we dataset ten wavecut scarps formed by...

This project utilizes Ocean Drilling Program (ODP) cores from Expedition 113 in the Weddell Sea and Integrated (IODP) ODP geophysical down-hole
<div> <p>Bivalve and gastropod shell beds deposited during the Early Pliocene (4.69-5.23 Ma) occur in uplifted outcrops (36 – 180 m above sea level) along east coast of Patagonian Argentina. These rock units provide a record level geologic period when atmospheric CO2 temperatures were higher than today. As such, reconstructing elevation global mean (GMSL) this time allows us to better understand how sensitive ice sheets are increased past future...
