Última An inverse model of the large scale circulation in the South Indian Ocean ArchiMer Sultan, Emmanuelle; Mercier, Herle; Pollard, R.t. An overview of the large-scale circulation of the South Indian Ocean (SIO) (10 degrees S-70 degrees S/20 degrees E-120 degrees E) is proposed based on historical hydrographic data (1903-1996) synthesized with a finite-difference inverse model. The in situ density, potential temperature and salinity fields of selected hydrographic stations are projected on the basis of EOFs. Then the EOF coefficients (the projected values) are interpolated on the model grid (1 degrees in latitude, 2 degrees in longitude) using an objective analysis whose spatial correlation functions are fitted to the data set. The resulting fields are the input of the inverse model. This procedure filters out the small-scale features. Twelve modes are needed to keep the vertical structures...

The concentrations of rare earth elements (REEs) in seawater display systematic variations related to weathering inputs, particle scavenging and water mass histories. Here we investigate the REE concentrations of water column profiles in the Atlantic sector of the Southern Ocean, a key region of the global circulation and primary production. The data reveal a pronounced contrast between the vertical profiles in the Antarctic Circumpolar Current (ACC) and those south of the ACC in the Weddell Gyre (WG). The ACC profiles exhibit the typical increase of REE concentrations with water depth and a change in the shape of the profiles from near linear for the light REEs to more convex for the heavy REEs. In contrast, the WG profiles exhibit high REE concentrations... Tipo: Text Palavras-chave: Rare earth elements; Atlantic sector of the Southern Ocean; Weddell Gyre; GEOTRACES.
