Abstract

Results demonstrated that the water column of the Gulf of Elat was saturated with an excess of anthropogenic CO2, indicating winter overturning. In the Red Sea, the upper 200 m are very young with a very uniform excess carbon dioxide signal close to zero (0±7 μmol kg-1). The ΔΣ CO0 2 values (the signal of anthropogenic CO2 penetration, after reaching maximum negative values ca -28±5 μmol kg-1 at 600±100 m, increase and remain almost constant at ca. -15±6 μmol kg-1 from 800 to 1500 m. The increase of ΔΣ CO0 2 values below 600±100 m in the northern Red Sea was explained by the influence of the overflow of younger waters from the Gulf of Elat over the sill in the Strait of Tiran and by the inflow of young waters from the Gulf of Suez. -from Authors
