| Summary: | ELEFANTE-12 Cruise (29HE20120119) carried out on the Research Vessel Hespérides in 2012 A physical-geological mooring is installed at the East of Elephant Island in order to monitor the presence / absence of the Antarctic slope front on the south slope of the South Scotia Sea, and to study its role in the modification of intermediate waters of the Antarctic Circumpolar Current. The addition of a sediment trap will study the flow of sediments associated with the dynamics of the area and identify terrigenous and biogenic composition. 1) Placement of an anchor constituted by current meters and temperature sensors, salinity and pressure at different depths, in addition to a sediment trap placed near the bottom. The anchor has a length of about 700 m and can be installed on a background of about 1200 m. 2 )Completion of several transects for water sampling using CTD. The purpose of these transects is to calibrate the anchored instruments and carry out a hydrographic survey of the slope front and the southern border of the circumpolar current at the moment of anchoring. The CTDs will be made to the bottom |
