Environmental Controls on Mg/Ca in Neogloboquadrina incompta: A Core‐Top Study From the Subpolar North Atlantic

Magnesium/calcium paleothermometry is an established tool for reconstructing past surface and deep‐sea temperatures. However, our understanding of nonthermal environmental controls on the uptake of Mg into the calcitic lattice of foraminiferal tests remains limited. Here we present a combined analys...
