Remote and Local Forcing in the Brazil–Malvinas Region
Publisher: American Meteorological Society
Abstract: Origins of the seasonal variability observed in current meter data from the Malvinas (Falkland) Current are sought in the wind field on both a regional and circumpolar scale. A singular value decomposition of the covariance ...
Eddy Heat Flux in the Southern Ocean: Response to Variable Wind Forcing
Publisher: American Meteorological Society
Abstract: The authors assess the role of time-dependent eddy variability in the Antarctic Circumpolar Current (ACC) in influencing warming of the Southern Ocean. For this, an eddy-resolving quasigeostrophic model of the wind-driven ...
Sensitivity of the Overturning Circulation in the Southern Ocean to Decadal Changes in Wind Forcing
Publisher: American Meteorological Society
Abstract: he sensitivity of the overturning circulation in the Southern Ocean to the recent decadal strengthening of the overlying winds is being discussed intensely, with some works attributing an inferred saturation of the Southern ...
Evolution of the Deep and Bottom Waters of the Scotia Sea, Southern Ocean, during 1995–2005
Publisher: American Meteorological Society
Abstract: The Southern Ocean hosts the formation of the densest layers of the oceanic overturning circulation and provides a climatically sensitive element of deep ocean ventilation. An oceanographic section across the eastern Scotia ...
Deep and Bottom Waters in the Eastern Scotia Sea: Rapid Changes in Properties and Circulation
Publisher: American Meteorological Society
Abstract: Two meridional hydrographic transects (in 1995 and 1999) across the eastern Scotia Sea are used to investigate variability in the deep and bottom waters between the South Scotia Ridge and South Georgia. There is a significant ...
The Processing and Application of Inverted Echo Sounder Data from Drake Passage
Publisher: American Meteorological Society
Abstract: Bottom pressure recorders (BPRs) have been deployed at Drake Passage (DP) to monitor changes in the volume transport of the Antarctic Circumpolar Current (ACC) through the passage. The use of inverted echo sounders (IESs) ...
Decadal Freshening of the Antarctic Bottom Water Exported from the Weddell Sea
Publisher: American Meteorological Society
Abstract: ecent decadal changes in Southern Hemisphere climate have driven strong responses from the cryosphere. Concurrently, there has been a marked freshening of the shelf and bottom waters across a wide sector of the Southern ...
The Freshwater System West of the Antarctic Peninsula: Spatial and Temporal Changes
Publisher: American Meteorological Society
Abstract: limate change west of the Antarctic Peninsula is the most rapid of anywhere in the Southern Hemisphere, with associated changes in the rates and distributions of freshwater inputs to the ocean. Here, results from the first ...
