| Summary: | Temperature data collected over the last 36 years (1969–2004) in Drake Passage are used to examine global sea level rise are potentially significant. Shepherd et al. (2004) suggest the ice discharge has been a source of ocean mass, equivalent to a 0.13 ± 0.02 mm yr1 rise in eustatic sea level over the past decade. This consequence of a warming ocean to global sea level rise is above and beyond the expected thermosteric con-tribution of 0.55 mm yr1 (Cabanes et al., 2001; Church et al., 2004). Southern Ocean have been limited to one particular depth (e.g. Gille, 2002) or to a few repeated sections occupied for a number of years (e.g. Aoki et al., 2003; Sokolov and Rintoul, 2003) or single repeat surveys that are decades apart (e.g. Bindoff and McDougall, 2000; Wong et al., 2001). Yet the dynamics of the climatic response in the air–ocean–sea ice system of the Southern Ocean may be very different if the anomalies are only confined to the surface layer. The ocean surface layer provides a boundary condition to both the deeper ocean and the overlying atmosphere in its direct re-sponse to the air–sea heat and freshwater flux. Below this surface layer, property changes may be related to changes in the wind |
