| Zusammenfassung |
| 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 ≡ 106 m3 s−1) and 13.4 ± 5.2 Sv, across the
main export regions of the Weddell and Ross Seas, respectively. The values of
mean outflow of Antarctic Bottom Water (AABW) (defined by neutral density
γn ≥ 28.27 kg m−3) from the Weddell and Ross Seas of
10.6 ± 3.1 Sv and 0.5 ± 0.7 Sv, respectively, agree with the
range reported in historical observational studies. The export of Weddell
Sea dense water in OCCAM is primarily determined by the strength of the
Weddell Gyre. Variability in AABW export is predominantly at periods of
~1 yr and 2–4 yr. |
