Recent planktonic foraminifera population and size response to Eastern Mediterranean hydrography
The eastern Mediterranean Sea is a partially isolated sea where excess evaporation over precipitation or riverine discharge results in large north to south gradients in temperature and salinity. Eastern Mediterranean Sea surface sediment samples from 28 locations spanning from the North Aegean to th...

The eastern Mediterranean Sea is a partially isolated sea where excess evaporation over precipitation or riverine discharge results in large north to south gradients in temperature and salinity.
