RISTransport of Bottom Water in the Romanche Fracture Zone and the Chain Fracture Zone
Publisher: American Meteorological Society
Abstract: Two moored arrays deployed in the Romanche Fracture Zone and Chain Fracture Zone in the equatorial Atlantic Ocean provide two-year-long time series of current and temperature in the Lower North Atlantic Deep Water and the ...
Space and Time Scales of Mesoscale Motions in the Eastern North Atlantic
Publisher: American Meteorological Society
Abstract: The Tourbillon experiment carried out in 1979?80 over the Porcupine Abyssal Plain in the eastern North Atlantic is the fist experiment providing data that allow an efficient description of the spatial structure of the ...
Circulation and Transport at the Southeast Tip of Greenland
Publisher: American Meteorological Society
Abstract: The circulation and related transports at the southeast tip of Greenland are determined from direct current observations of a moored current meter array. The measurements cover a time span from June 2004 to June 2006. The ...
An Inverse Model of the North Atlantic General Circulation Using Lagrangian Float Data
Publisher: American Meteorological Society
Abstract: A nonlinear finite-difference inverse model is used for estimating the North Atlantic general circulation between 20° and 50°N. The inverse model with grid spacing 2° latitude and 2.5° longitude is based on hydrography and ...
Dissipation Rate Estimates from Microstructure and Finescale Internal Wave Observations along the A25 Greenland–Portugal OVIDE Line
Publisher: American Meteorological Society
Abstract: total of 96 finestructure and 30 microstructure full-depth vertical profiles were collected along the A25 Greenland?Portugal Observatoire de la Variabilité Interannuelle et Décennale en Atlantique Nord (OVIDE) hydrographic ...
Altimetry Combined with Hydrography for Ocean Transport Estimation
Publisher: American Meteorological Society
Abstract: method to estimate mass and heat transports across hydrographic sections using hydrography together with altimetry data in a geostrophic inverse box model is presented. Absolute surface velocities computed from Archiving, ...
Direct Observations of the Mean Circulation at 48°N in the Atlantic Ocean
Publisher: American Meteorological Society
Abstract: Eulerian velocity measurements carried out along 48°N in the Atlantic Ocean Provide averaged velocities with definite large-scale structure. This warrants an analysis of these mean velocity vectors within the framework of ...
Effects of the Mixed Layer Time Variability on Kinematic Subduction Rate Diagnostics
Publisher: American Meteorological Society
Abstract: An eddy-resolving primitive equation general circulation model is used to estimate water-mass subduction rates in the North Atlantic Ocean subtropical gyre. The diagnostics are based on the instantaneous kinematic approach, ...
Mixing in the Romanche Fracture Zone
Publisher: American Meteorological Society
Abstract: The Romanche Fracture Zone is a major gap in the Mid-Atlantic Ridge at the equator, which is deep enough to allow significant eastward flows of Antarctic Bottom Water from the Brazil Basin to the Sierra Leone and Guinea ...
On the Cascading of Dense Shelf Waters in the Irminger Sea
Publisher: American Meteorological Society
Abstract: ydrographic data collected in the Irminger Sea in the 1990s?2000s indicate that dense shelf waters carried by the East Greenland Current south of the Denmark Strait intermittently descend (cascade) down the continental ...
