Collection of 451 temperature profiles with XBT and 35 profiles of temperature and salinity with XCTD probes in the Drake Strait, the Weddell Sea and between the northern tip of the Antarctica Paeninsula and the Orcadas Islands, to study of the variability of the Mixed Layer and the estimate of the heat content on the first 700 m of the water column, and the large scale representation of the surace and subsurface structure of the ACC. Three oceanographic cruises were performed on board of the Argentinean ice breaker “Almirante Irizar” in the three austral winters 2004-2005, 2005-2006 e 2006-2007. Data are acquired from the 7th of february and the sond were launched with a resolution of 20' of latitude to 70° ad 15' for higher latitudes, to better define the thermal southern front.
The Ice-ClimaLizer research investigates the role of two Antarctic bioconstructional and bioindicator organisms (bryozoan and coralline algae), responsible of promoting marine biodiversity, as proxies of environmental conditions (temperature, light intensity, pressure, oxygen, conductibility and pH). An experimental laboratory has been placed in Tethys Bay (Ross Sea) at 25.5 m deep. The project will compare 1 year of environmental data obtained via continuous recording (every hour) by CTD probe with reconstructed data obtained via geochemical proxies of skeletons/thalli of the investigated species. Data are collected from November 2018 to November 2019.
