Water mass export from Drake Passage to the Atlantic, Indian, and Pacific Oceans: a Lagrangian model analysis / Yann Friocourt, Sybren Drijfhout, Bruno Blanke, Sabrina Speich.

Title: Water mass export from Drake Passage to the Atlantic, Indian, and Pacific Oceans: a Lagrangian model analysis / Yann Friocourt, Sybren Drijfhout, Bruno Blanke, Sabrina Speich.

Date: 2005.
In: Journal of Physical Oceanography. (2005.), Vol. 35(7) (2005)
Abstract: Northward export of intermediate water from Drake Passage is investigated in two global ocean general circulation models by means of quantitative particle tracing diagnostics. Atlantic and Pacific Oceans are main catchment basins, but most water exported to Atlantic equator loops first into Indian Ocean subtropical gyre, flowing eventually into Atlantic by Agulhas leakage. Discusses difficulties associated with relating export from Drake Passage towards equator to wind stress over Southern Ocean, as theory cannot be applied to individual basins because of interocean exchanges through supergyre mechanism and other non-linear processes. Export of water from Drake Passage starts mainly as Ekman flow just northward of latitude band of Antarctic Circumpolar Current south of South America. Waters quickly subduct and are transferred to ocean interior as they travel equatorward. They flow along eastern boundaries in Sverdrup interior and cross southern basins north-westward to reach equator within western boundary current systems.
