This $374,395 National Science Foundation project grant through the Geosciences program (CFDA 47.050) will fund research at Rutgers University and Princeton University from December 2022 through November 2024. The grant supports the identification of silicate diagenesis processes controlling pore fluid chemistry in marine sediments and their influence on the geochemical budgets of magnesium, strontium, lithium, and boron through analysis of pore fluid samples from the Mid-Norwegian Margin. High-resolution isotopic analysis of the samples using MC-ICP-MS will provide unprecedented constraints on how silicate diagenesis regulates seawater chemistry and facilitates environmental change. Insights gained will enhance proxy-based and model-based reconstructions of warmer climates in Earth's history. Public outreach activities are also supported.
