Long-term Phanerozoic global mean sea level: Insights from strontium isotope variations and estimates of continental glaciation

Global mean sea level is a key component within the fields of climate and oceanographic modelling in Anthropocene. Hence, an improved understanding eustatic deep time aids our Earth’s paleoclimate may help predict future climatological changes. However, long-term reconstructions are hampered because ambiguity stratigraphic interpretations rock record limitations plate tectonic modelling. Hence amplitude timescales Phanerozoic eustasy remains poorly constrained. A novel, independent method from or methods, based on estimating effect tectonics (i.e., mid-ocean ridge spreading) 87Sr/86Sr led to curve, but did not include glacio-eustatic drivers. Here, we incorporate changes resulting variations seawater volume continental glaciations at steps 1 Myr. Based recent compilation global average paleotemperature derived ?18O data, paleo-Köppen zones paleogeographic reconstructions, estimate ice distribution land shelf margins. Ice thickness calibrated with model for late Cenozoic icehouse, yielding ?1.4 km ice, ultimately providing estimates. Eustatic associated (>1 Myr) reach up ?90 m, similar to, times dominant over tectonic-derived eustasy. We superimpose effects tectonically driven record. This results Tectono-Glacio-Eustatic (TGE) curvefor which describe main (>50 residual trends detail.
