Semidiurnal Tides on the Laptev Sea Shelf with Implications for Shear and Vertical Mixing
Publisher: American Meteorological Society
Abstract: he Arctic continental shelf seas hold a globally significant source of freshwater that impacts Arctic Ocean stratification, circulation, and climate. This freshwater can be injected below the surface mixed layer by intense ...
Observations of Ekman Currents in the Southern Ocean
Publisher: American Meteorological Society
Abstract: Largely zonal winds in the Southern Ocean drive an equatorward Ekman transport that constitutes the shallowest limb of the meridional overturning circulation of the Antarctic Circumpolar Current (ACC). Despite its importance, ...
Improving Estimates of the Antarctic Circumpolar Current Streamlines in Drake Passage
Publisher: American Meteorological Society
Abstract: Accurately resolving the mean Antarctic Circumpolar Current (ACC) is essential for determining Southern Ocean eddy fluxes that are important to the global meridional overturning circulation. Previous estimates of the mean ...
Observed Atlantification of the Barents Sea Causes the Polar Front to Limit the Expansion of Winter Sea Ice
Publisher: American Meteorological Society
Abstract: AbstractBarents Sea Water (BSW) is formed from Atlantic Water that is cooled through atmospheric heat loss and freshened through seasonal sea ice melt. In the eastern Barents Sea, the BSW and fresher, colder Arctic Water ...
Shear at the Base of the Oceanic Mixed Layer Generated by Wind Shear Alignment
Publisher: American Meteorological Society
Abstract: bservations are used to evaluate a simple theoretical model for the generation of near-inertial shear spikes at the base of the open ocean mixed layer when the upper ocean displays a two-layer structure. The model predicts ...
Near-Surface Eddy Heat and Momentum Fluxes in the Antarctic Circumpolar Current in Drake Passage
Publisher: American Meteorological Society
Abstract: he authors present new estimates of the eddy momentum and heat fluxes from repeated high-resolution upper-ocean velocity and temperature observations in Drake Passage and interpret their role in the regional Antarctic ...
Can Drake Passage Observations Match Ekman's Classic Theory?
Publisher: American Meteorological Society
Abstract: kman's theory of the wind-driven ocean surface boundary layer assumes a constant eddy viscosity and predicts that the current rotates with depth at the same rate as it decays in amplitude. Despite its wide acceptance, Ekman ...
Intermittent Intense Turbulent Mixing under Ice in the Laptev Sea Continental Shelf
Publisher: American Meteorological Society
Abstract: Vertical mixing in the bottom boundary layer and pycnocline of the Laptev Sea is evaluated from a rapidly sampled 12-h time series of microstructure temperature, conductivity, and shear observations collected under 100% ...
