Large sea surface temperature, salinity, and productivity‐preservation changes preceding the onset of the Messinian Salinity Crisis in the eastern Mediterranean Sea
Abstract The Messinian Salinity Crisis (MSC; 5.97–5.33 Ma) is an enigmatic episode of
paleoceanographic change, when kilometer‐thick evaporite units were deposited in the …
