Estimation of Meridional Heat Flux in the North Atlantic by Inverse Methods
Publisher: American Meteorological Society
Abstract: Hydrographic sections spanning the Atlantic Ocean at 24, 36 and 48°N are used to make an estimate of meridional heat flux in the ocean. An inverse method provides reference level velocities for geostrophic calculations, ...
Indirect Sensing of Equatorial Currents by Means of Island Pressure Measurements
Publisher: American Meteorological Society
Abstract: From November 1982 until March 1983, an experiment was conducted at Jarvis Island (0.4°S, 160°W) in order to study the energetics of swift currents encountering a small equatorial island, and to determine the relationship ...
The Balance of Geostrophic and Ekman Transports in the Tropical Atlantic Ocean
Publisher: American Meteorological Society
Abstract: Hydrographic station data from 24°N, 8°N, 8°S and 24°S in the Atlantic Ocean are used to calculate geostrophic transport in eight layers separated by isopycnal surfaces. In the upper ocean, the geostrophic transport is ...
Optimal Estimation of Hydrographic Station Data and Derived Fields
Publisher: American Meteorological Society
Abstract: Optimal estimation is applied to contouring and analysis of hydrographic sections. Measured fields, such as temperature and salinity, and derived fields, such as geostrophic velocity, are decomposed into large-scale and ...
The Subtropical Mode Waters of the South Pacific Ocean
Publisher: American Meteorological Society
Abstract: The subtropical mode waters (STMW) of the southwestern Pacific Ocean are described, including their physical characteristics, spatial distribution, and temporal variability. STMW is a thermostad, or minimum in stratification, ...
Eddy Transport of Heat and Thermocline Waters in the North Pacific: A Key to Interannual/Decadal Climate Variability?
Publisher: American Meteorological Society
Abstract: High-resolution XBT transects in the North Pacific Ocean, at an average latitude of 22°N, are analyzed together with TOPEX/Poseidon altimetric data to determine the structure and transport characteristics of the mesoscale ...
Is the North Atlantic in Sverdrup Balance?
Publisher: American Meteorological Society
Abstract: Evidence for the widespread assumption that Sverdrup balance describes the dynamics of the North Atlantic subtropical gyre is reviewed critically. If the balance were to hold up to the edge of the Gulf Stream system, then ...
Observing the Fluctuations of Gyre-Scale Ocean Circulation: A Study of the Subtropical South Pacific
Publisher: American Meteorological Society
Abstract: Seasonal and interannual variability of the subtropical gyre in the South Pacific Ocean are investigated by means of a time series of expendable bathythermograph (XBT) sections between New Zealand (36°S, 175°E) and Fiji ...
Sensitivity of Western Boundary Transport at the Mean North Equatorial Current Bifurcation Latitude to Wind Forcing
Publisher: American Meteorological Society
Abstract: he bifurcation of the North Equatorial Current (NEC) plays an important role in the heat and water mass exchanges between the tropical and subtropical gyres in the Pacific Ocean. The variability of western boundary transport ...
Wind-Driven Variability of the Subtropical North Pacific Ocean
Publisher: American Meteorological Society
Abstract: he Argo array provides a unique dataset to explore variability of the subsurface ocean interior. This study considers the subtropical North Pacific Ocean during the period from 2004 to 2011, when Argo coverage has been ...
