Calcium isotope ratios of malformed foraminifera reveal biocalcification stress preceded oceanic anoxic event 2

HIGHLIGHTS

• who: Gabriella D. Kitch from the Northwestern University have published the research: Calcium isotope ratios of malformed foraminifera reveal biocalcification stress preceded Oceanic Anoxic Event 2, in the Journal: (JOURNAL) of 11/02/2022
• what: Using an integrated timescale to compare these Osi records to the u03b444 /40Ca records (see Supplementary Fig 5) the authors show that the positive u03b444/40Ca excursions coincide with decreases in Osi (Fig 4).
• future: While additional studies are needed to examine species-specific effects on u0394CaCO3 H2 O correlating the data to existing proxies for volcanic activity . . .
