RISA Deep Eddy in the Antarctic Intermediate Water North of the Chatham Rise
Publisher: American Meteorological Society
Abstract: In mid-1996, a hydrographic survey was made over the Chatham Rise, near New Zealand. A deep isolated eddy of Antarctic Intermediate Water was found north of the rise between 1200 and 1800 dbar. It was widest on a potential ...
Multidecadal Change of the South Pacific Gyre Circulation
Publisher: American Meteorological Society
Abstract: ultidecadal trends in ocean heat and freshwater content are well documented, but much less evidence exists of long-term changes in ocean circulation. Previously, a 12-yr increase, 1993 to 2004, in the circulation of the ...
Closing the Time-Varying Mass and Heat Budgets for Large Ocean Areas: The Tasman Box
Publisher: American Meteorological Society
Abstract: The role of oceanic advection in seasonal-to-interannual balances of mass and heat is studied using a 12-yr time series of quarterly eddy-resolving expendable bathythermograph (XBT) surveys around the perimeter of a region ...
Interannual Variability of Sea Surface Temperature in the Southwest Pacific and the Role of Ocean Dynamics
Publisher: American Meteorological Society
Abstract: AbstractThis paper investigates the mechanisms causing interannual variability of upper ocean heat content and sea surface temperature (SST) in the southwest Pacific. Using the ECCOv4 ocean reanalysis it is shown that ...
