On the outflow of dense water from the Weddell and Ross Seas in OCCAM model
We describe the seasonal and interannual variability of volume transports in the Weddell and Ross Seas using the 1/12° 20-yr simulation of the OCCAM global ocean general circulation model. The average simulated full-depth cumulative volume transports were 28.5 ± 2.9 Sv (1 Sv ≡ 10 6 m 3 s −1 ) and 13...
