Past diatoms bloom and Foraminifer extinction detected in old Adriatic sediments

The finding in two cores, collected in the Southern Adriatic, of sediments rich in diatoms and radiolaria and almost completely lacking in benthic forams, testifies to an environmental situation comparable with that in the Northern Adriatic. This situation must have persisted for long enough to be registered in the sediment. It is interpreted as the Adriatic's response to the extreme oceanographic conditions causing deposition of the Sapropel S1 in the Eastern Mediterranean
