Groundwater discharge impacts marine isotope budgets of Li, Mg, Ca, Sr, and Ba
KK Mayfield, A Eisenhauer… - Nature …, 2021 - nature.com
Groundwater-derived solute fluxes to the ocean have long been assumed static and
subordinate to riverine fluxes, if not neglected entirely, in marine isotope budgets. Here we …

A productivity collapse to end Earth's Great Oxidation
It has been hypothesized that the overall size of—or efficiency of carbon export from—the
biosphere decreased at the end of the Great Oxidation Event (GOE)(ca. 2,400 to 2,050 Ma) …

Toward an improved understanding of the marine barium cycle and the application of marine barite as a paleoproductivity proxy
Marine barite (BaSO4) is a relatively ubiquitous, though minor, component of ocean
sediments. Modern studies of the accumulation of barite in ocean sediments have …
