A Deep Stepped Thermohaline Structure Deep in the Mediterranean

Abstract

A deep stepped thermohaline structure has been observed in the Tyrrhenian Sea below the Levantine water salinity maximum. The layers are remarkably homogeneous starting with a thickness of 10 m - 20 m at 600 m and thereafter increasing dramatically to 200 m thickness at 1200 m depth. The thickness of the interfaces between the layers is a few metres or less with typical changes of 0.05 deg C - 1 deg C and -0.02%, for 'temperature and salinity 'respectively decreasing with depth. The identity of the layers is sustained over a horizontal distance of at least 75 n.mi and at a point for a time interval of more than a year.
