Carbon-cycle changes during the Toarcian (Early Jurassic) and implications for regional versus global drivers of the Toarcian oceanic anoxic event
MN Remírez, TJ Algeo - Earth-Science Reviews, 2020 - Elsevier
Abstract The Early Jurassic Toarcian oceanic anoxic event (T-OAE) is characterized by an
extinction event, a major sea-level rise, enhanced marine primary productivity, elevated …

230Th Normalization: New Insights on an Essential Tool for Quantifying Sedimentary Fluxes in the Modern and Quaternary Ocean
Abstract 230Th normalization is a valuable paleoceanographic tool for reconstructing high‐

I/Ca in epifaunal benthic foraminifera: A semi-quantitative proxy for bottom water oxygen in a multi-proxy compilation for glacial ocean deoxygenation
The decline in dissolved oxygen in global oceans (ocean deoxygenation) is a potential
consequence of global warming which may have important impacts on ocean …
