In the East Mediterranean Deep Thermohaline Cell (Engine) getting into a stall? H. Kontoyiannis, G.P. Gasparini, S. Sparnoccia, V. Lykousis Water properties (temperature, salinity, dissolved oxygen, ..transparency (… to a certain degree) in the deep (near-bottom) oceanic layers depend on the deep thermohaline cell, i.e., a series of phenomena/mechanisms that start from The deep/dense water formation … at certain regions The spreading to the deep layers The filling of the basins … Preservation and evolution of the original site formation properties through mixing with surrounding waters
ADW In 1998 the ADW circulated around 1000m (Theocharis et al., 2002) CDW In 1995 the ADW appeared above the deep and bottom CDW (Theocharis et al., 2002) ADW C D W In 1997-98 no deep convection (~400m) was reported in the Adriatic (Manca et al., 2002) In 1999 the ventilation went deeper (~700m) (Manca et al., 2002)
