The oxygen-isotopic record and microfossils from deep-sea cores raised in the hypersaline (41‰ salinity) Gulf of Aqaba indicate that during Late Quaternary glacial time salinity rose considerably due to sea-level fall and strait-dynamics, reaching values of more than 50‰ during the last Glacial maximum about 18 Ka B.P. The salinity-dependent sequence of disappearance of various species of foraminifera, pteropods and coccolithophorids can be used to determine upper salinity tolerance limits of different taxa. Only the pteropod Creseis acicula and various benthonic foraminifera are able to withstand high salinities like those during the last glacial maximum.
