Large scale circulation in the South Atlantic: estimates from giant iceberg drift rates
Abstract: The paper reports work currently in progress and presents estimates for ocean ... circulation in the Scotia Sea. The estimates are derived from the drift rates of giant icebergs calved in the ... Weddell Sea since 1974. Comparison with other estimates is limited by the lack of studies reported in the ... literature, however, efforts to make these comparisons are in hand. Author(s): P.N. Trathan and C. Symon ...
