XBT REPEATED OBSERVATION PROGRAMME

Since 1994 The PNRA (Italian National Antarctic Research Program) funded several research programmes focused on the study of southern Ocean thermal properties across the Antarctic Circumpolar Current.
These project and their evolution represent today one of the Italian contribution to the Southern Ocean Observing System (SOOS).
Italian monitoring of upper layer temperature characteristics of the SO started in the framework of the CLIMA (Climatic Long-term Interactions for the Mass Balance in Antarctica) project and lasted for about 15 years (1994-2017), white lines represent the mean position of ACC fronts in the area.
In more recent years monitoring activities have been developed in the framework of the SOCHiC (Southern Ocean observing CHokepoints: Italian Contribution), and MORSea (Marine Observatory in the Ross Sea) projects.
In situ eXpendable BathyTermograph (XBT) observations (see following paragraph for details), combined with continuous surface layer monitoring from ship, Argo temperature-salinity profiles and with satellite products, are used along the repeated transects to study the link between local wind forcing mechanisms and the long term variability and the dynamics of the ACC fronts south of South Africa, New Zealand and in the Drake Passage.
These projects have led to build various partnership between the University of Naples “Parthenope” and international research institutions such as the South Africans research centres involved in the SAMOC (South Atlantic’s branch of the Meridional Overturning Circulation) project and the Argentines Institution involved in the CANOPO (the Role of the Atlantic Sector of the Southern Ocean in CO2 Sequestration) project.
Moreover the Italian research activities have been carried on using various foreign facilities and research vessels (i.e.: Irizar, Palmer, Agulhas, Agulhas II, Araon)

Research activities along the South Africa – Antarctica have been possible thanks to the cooperation with the university of Cape Town (UCT) and the Council for Scientific and Industrial Research (CSIR). During each cruise an Italian scientist has been hosted onboard of the R/Vs Agulhas or Agulahs II.
