Testing for ocean acidification during the Early Toarcian using δ 44/40 Ca and δ 88/86 Sr ...
During the Early Toarcian, volcanic gases released by the Karoo-Ferrar large igneous province are widely believed to have caused severe environmental disturbances, including ocean acidification. Here we show records of δ Ca and δ Sr through the Early Toarcian, as recorded in three groups of biogenic...
