Intensification of Geostrophic Currents in the Canada Basin, Arctic Ocean
Publisher: American Meteorological Society
Abstract: ontinuous sampling of upper-ocean hydrographic data in the Canada Basin from various sources spanning from 2003 through 2011 provides an unprecedented opportunity to observe changes occurring in a major feature of the ...
A Study of Oceanic Boundary-Layer Characteristics Including Inertial Oscillation at Three Drifting Stations In the Arctic Ocean
Publisher: American Meteorological Society
Abstract: Measurements of surface drift and near-surface currents taken during August 1975, at drifting ice stations of the AIDJEX experiment in the central Arctic, are used to infer the response of the upper ocean to the passage ...
The Effect of the Oceanic Boundary Layer on the Mean Drift of Pack Ice: Application of a Simple Model
Publisher: American Meteorological Society
Abstract: Smoothed records of ice drift, surface wind and upper ocean currents at four manned stations of the 1975?76 AIDJEX experiment in the central Arctic have been analyzed to provide a statistical relationship between stress ...
Marginal Thermobaric Stability in the Ice-Covered Upper Ocean over Maud Rise
Publisher: American Meteorological Society
Abstract: Temperature (T) and salinity (S) profiles from the central Weddell Sea near the Maud Rise seamount measured during the 1994 Antarctic Zone Flux Experiment (ANZFLUX) have been analyzed for stability with respect to the ...
A Spectral Technique for Estimating Turbulent Stress, Scalar Flux Magnitude, and Eddy Viscosity in the Ocean Boundary Layer under Pack Ice
Publisher: American Meteorological Society
Abstract: The hypothesis is tested that, for the planetary boundary layer, turbulent vertical velocity (w) spectral density, normalized by u2?/k (u2? is Reynolds stress magnitude and k is wavenumber: 2π times frequency divided by ...
Measurements of the Turbulent Boundary Layer under Pack Ice
Publisher: American Meteorological Society
Abstract: The mean and turbulent flow structure under pack ice was measured during the 1972 AIDJEK pilot study with small mechanical current meter triplets at eight levels in the planetary boundary layer. CTD profiles showed a ...
Ice-Seawater Turbulent Boundary Layer Interaction with Melting or Freezing
Publisher: American Meteorological Society
Abstract: A second-moment, turbulence closure model is applied to the problem of the dynamic and thermodynamic interaction of sea ice and the ocean surface mixed layer. In the case of ice moving over a warm, ocean surface layer, ...
Ocean Heat Flux in the Central Weddell Sea during Winter
Publisher: American Meteorological Society
Abstract: Seasonal sea ice, which plays a pivotal role in air?sea interaction in the Weddell Sea (a region of large deep-water formation with potential impact on climate), depends critically on heat flux from the deep ocean. During ...
