Item Hydrography of the Bransfield Strait during 1984 Southern Summer. SIBEX - Phase I(1998) Kelly, Rolando; Blanco, José; Díaz, MaidaThe SIBEX (Phase I) expedition was realized in the Bransfield Strait and adjacent zones between January 27th and February 10th, 1984, on board the R/V Capitán Luis Alcázar. Forty seven (47) oceanographic stations were performed, down to a maximum depth of 700 m. The variables measured were temperature, salinity and dissolved oxygen. To study its distributions, graphs of vertical and horizontal sections were prepared. Water masses and types were studied by means of T-S diagrams; geopotential anomaly of the sea surface relative to the pressure levels of 1 MPa and 2 MPa and stability of the surface layer were also analyzed. The results showed some differences with the ones obtained during FIBEX. Sea surface temperature and salinity were in general higher in all the studied area. The water masses and types identified coincided with the ones described for FIBEX, with differences in the surface layer which was warmer. The geopotencial topography showed a main flow to the NE in the center and northern part of the strait. The southern part showed a flow to the SW generated in the Antarctic Sound which runs up to Trinity island and then it joins the main flow.
