Reuters: John Church of the Australian government-backed Commonwealth Scientific and Industrial Research Organisation has called for the establishment of a network of deep ocean moorings to extend a system already in operation in the northern hemisphere. Church is a senior science adviser to the U.N.-backed World Climate Research Programme.Probes should be strung across the South Atlantic and through the Indonesian archipelago, as well as in the Southern Ocean in order to warn of changes in ocean circulation that may affect the global climate says Church.
