Baroclinic Instability in the Denmark Strait Overflow
Publisher: American Meteorological Society
Abstract: Current meter records and hydrographic data taken in the Denmark Strait overflow during a one-month experiment in August-September 1973 are analyzed. Mean conditions indicate that a strong, cold overflow current existed ...
The Mean and Seasonal Circulation off Southwest Nova Scotia
Publisher: American Meteorological Society
Abstract: Long-term measurements off southwest Nova Scotia reveal the following features of the mean circulation: (a) a westward longshore coastal current (4?10 cm s?1, (b) an anticyclonic gyre around Brown Bank (5?15 cm s?1, and ...
The Development of the Barotropic Radiation Field of an Eddy over a Slope
Publisher: American Meteorological Society
Abstract: Low-frequency current measurements near the shelf break south of Nova Scotia indicate that the presence of topographic waves on the continental slope, and rise is associated with large-scale shoreward excursions and formation ...
Low-Frequency Circulation at the Edge of the Scotian Shelf
Publisher: American Meteorological Society
Abstract: Records of current, temperature and salinity from a two-year mooring program at the shelf break off Nova Scotia are examined to determine the low-frequency oceanic responses to the driving surface wind field and fluctuating ...
Estimation and Verification of Tidally Induced Residual Currents
Publisher: American Meteorological Society
Abstract: Using a multiple regression technique that includes both tidal and wind forcings, the tidally-induced residual current can be estimated from current meter records. However, the estimated mean (long-term averaged) tidally ...
Observations of Topographic Rossby Waves on the Continental Margin off Nova Scotia
Publisher: American Meteorological Society
Abstract: Bursts of topographic-Rossby-wave energy have been observed in data recorded by an array of current meters moored on the outer continental shelf and slope off Nova Scotia north of the Gulf Stream. The waves persist for ...
Topographic Upwelling off Southwest Nova Scotia
Publisher: American Meteorological Society
Abstract: The waters off Cape Sable in southwestern Nova Scotia have anomalously low temperatures and high nutrients during summer. Using a three-dimensional tidal model as well as field observations obtained between 1978 and 1985, ...
Seasonal-Mean Hydrography and Circulation in the Gulf of St. Lawrence and on the Eastern Scotian and Southern Newfoundland Shelves
Publisher: American Meteorological Society
Abstract: The climatological seasonal-mean hydrography and circulation in the Gulf of St. Lawrence and on the eastern Scotian and southern Newfoundland shelves are studied by reconstructing high-resolution temperature, salinity, and ...
The Steady-State Barotropic Response of the Gulf of Maine and Adjacent Regions to Surface Wind Stress
Publisher: American Meteorological Society
Abstract: The response of the Gulf of Maine region to steady, spatially uniform wind stress is examined using a linearized numerical model, with the influence of the strong tidal currents in the region included in the bottom stress ...
