25-Day Period Large-Scale Oscillations in the Argentine Basin Revealed by the TOPEX/Poseidon Altimeter
(American Meteorological Society, 2001)The measurement of the global sea surface height made by the TOPEX/Poseidon satellite has provided the first synoptic view of large-scale oceanic variability at intraseasonal scales from weeks to months. Areas of significant ... -
3D Structure of Striations in the North Pacific

3H and 3He in the Beta Triangle: Observations of Gyre Ventilation and Oxygen Utilization Rates
(American Meteorological Society, 1987)Isopycnal maps of 3H?3He age (τ) with about 100 km resolution have been obtained for a 1000-km scale area in the eastern subtropical North Atlantic. The midscale texture of the maps is consistent with isopycnal diffusivities ... -
A 20-Yr Average of the Indonesian Throughflow: Regional Currents and the Interbasin Exchange
(American Meteorological Society, 2008)Twenty years of monthly or more frequent repeat expendable bathythermograph data are used to estimate the mean geostrophic velocity and transport relative to 750 m of the Indonesian Throughflow (ITF) and its partitioning ... -
A Baroclinic Tide in the Eastern North Pacific Determined from 1000-km Acoustic Transmissions
(American Meteorological Society, 1997)In the summer of 1989 a 1000-km acoustic experiment in the eastern North Pacific showed a semidiurnal variation in pulse travel time that was coherent in depth and varied systematically across time fronts. The effect of a ... -
A Barotropic Model of Eddy Saturation
(American Meteorological Society, 2018)AbstractEddy saturation refers to a regime in which the total volume transport of an oceanic current is insensitive to the wind stress strength. Baroclinicity is currently believed to be the key to the development of an ... -
A Basinwide Estimate of Vertical Mixing in the Upper Pycnocline: Spreading of Bomb Tritium in the North Pacific Ocean
(American Meteorological Society, 1999)The vertical diffusivity KV in the upper half-kilometer of the North Pacific subtropical pycnocline is estimated from observations of the spreading rate of anthropogenic tritium. The calculation is based on approximately ... -
A Benthic Front in the Straits of Florida and Its Relationship to the Structure of the Florida Current
(American Meteorological Society, 1999)Observations from CTD tow-yos and microstructure profiles indicate the presence of a benthic front near 450-m depth on the western side of the Straits of Florida at 27°N. The front is at midslope and approximately beneath ... -
A Bernoulli Inverse Method for Determining the Ocean Circulation
(American Meteorological Society, 1986)A new inverse method for finding the large-scale ocean circulation is described. Unlike most previous methods it uses no horizontal gradient information, and is designed for widely spaced data. The method assumes that ... -
A Bottom Boundary Layer-resolving Three-Dimensional Tidal Model: A Sensitivity Study of Eddy Viscosity Formulation
(American Meteorological Society, 1993)A three-dimensional hydrodynamic model of the Irish Sea that resolves the bottom boundary layer, including the logarithmic layer, is developed. A finite-difference grid is employed in the horizontal, with the current profile ... -
A Bottom Current Along the Shelf Break
(American Meteorological Society, 1975)The theory of Hill and Johnson for upwelling over the shelf break is modified to give agreement with the work of Killworth. It is shown that when upwelling occurs over a discontinuity in bottom slope, this upwelling does ... -
A Bulk Turbulent Air–Sea Flux Algorithm for High-Wind, Spray Conditions
(American Meteorological Society, 2008)Sensible and latent heat can cross the air?sea interface by two routes: as interfacial fluxes controlled by molecular processes right at the interface, and as spray fluxes from the surface of sea spray droplets. Once the ... -
A Buoy and Ship Examination of the Subtropical Convergence South of Western Australia
(American Meteorological Society, 1978)The eddying behavior of a satellite-tracked buoy near the subtropical convergence zone south of Australia prompted a ship survey of the area. The buoy's behavior over several months suggested a quasi-stable current pattern ... -
A Buoyancy Flux-Driven Cyclonic Gyre in the Labrador Sea
(American Meteorological Society, 1987)The generation mechanism for a wintertime cyclonic gyre in the western Labrador Sea, first observed by Clarke and Gascard, is studied by using simple theoretical models. It is shown that atmospheric cooling, which occurs ... -
A Calculation of Ocean Heat Storage and Effective Ocean Surface Layer Depths for the Northern Hemisphere
(American Meteorological Society, 1984)In the hierarchy of simple ocean formulations available for coupling to atmospheric GCMs, a scheme whereby ocean surface-layer depths vary geographically and seasonally is deemed better than a fixed depth layer at all ... -
A Case Study of Wave–Current Interaction in a Strong Tidal Current
(American Meteorological Society, 1996)During August 1991, a field program was carried out in the vicinity of Cape St. James, off the British Columbia coast, where a strong tidally driven flow interacts with an active wave climate. Surface current maps were ... -
A Case Study of Wave–Current–Bathymetry Interactions at the Columbia River Entrance
(American Meteorological Society, 1984)A unique set of field observations has documented intense wave?current?bathymetry interactions in a tidal inlet, providing a severe test of existing wave theory. Hourly wave spectral estimates were acquired over ten complete ... -
A Climatological Interpretation of the Circulation in the Western South Pacific
(American Meteorological Society, 2002)Time-averaged circulation is examined using historical hydrographic data near the Australia and Papua New Guinea coast in the Pacific. By averaging the data along isopycnal surfaces in a 0.5° ? 0.5° grid, the authors are ... -
A Climatological Interpretation of the Circulation in the Western South Pacific
(American Meteorological Society, 2002)Time-averaged circulation is examined using historical hydrographic data near the Australia and Papua New Guinea coast in the Pacific. By averaging the data along isopycnal surfaces in a 0.5° ? 0.5° grid, the authors are ... -
A Climatological View of the Kuroshio/Oyashio System East of Japan
(American Meteorological Society, 2001)Time-averaged structure of the Kuroshio/Oyashio system east of Japan was examined using historical hydrographic data. Unlike most of the earlier climatological analyses, the data were averaged along isopycnal rather than ...
