| Abstract | GOODHOPE is an observational project, named GOODHOPE by the Cape of Good Hope, within an International partnership. The international partnership is gathering together means (in terms of human, observing platforms, ship time and general financial support) from 11 different institutions and six countries (France, South Africa, United States, Germany, Russia and Spain). The project has been approved in 2003 by the International CLIVAR panel and endorsed by SCAR[2] and CliC[3]. The project aims at studying the full-depth oceanic exchanges between the Indian, Atlantic and Southern oceans, in a latitude band that encompasses the subtropical domain between South Africa and the Subtropical Front (~35°S-40°S), and the ACC (~40°S-55°S). Specific objectives are a better knowledge of the temporal variability of the ACC transport, a study of property modifications experienced by the exchanged waters, an improved understanding of the mechanisms involved in these exchanges throughout the water column and, of course, a long term monitoring of water properties, dynamics and air-sea exchanges in time. |
