Evolution of the Deep Water in the Canadian Basin in the Arctic Ocean
Publisher: American Meteorological Society
Abstract: An overflow of magnitude 0.25 Sv (Sv ≡ 106 m?3 s?1) has been predicted to enter the Makarov Basin (part of the Canadian Basin in the Arctic Ocean) from the Eurasian Basin via a deep gap in the dividing Lomonosov ridge. The ...
Dynamics in the Deep Canada Basin, Arctic Ocean, Inferred by Thermistor Chain Time Series
Publisher: American Meteorological Society
Abstract: A 50-day time series of high-resolution temperature in the deepest layers of the Canada Basin in the Arctic Ocean indicates that the deep Canada Basin is a dynamically active environment, not the quiet, stable basin often ...
Does Rotation Influence Double-Diffusive Fluxes in Polar Oceans?
Publisher: American Meteorological Society
Abstract: he diffusive (or semiconvection) regime of double-diffusive convection (DDC) is widespread in the polar oceans, generating ?staircases? consisting of high-gradient interfaces of temperature and salinity separated by ...
Two-Layer Rotating Exchange Flow between Two Deep Basins: Theory and Application to the Strait of Gibraltar
Publisher: American Meteorological Society
Abstract: Rotating two-layer exchange flow over a sill in a strait separating two relatively deep and wide basins is analyzed. Upstream of the sill in the deep upstream basin, the infinitely deep dense lower layer is assumed to be ...
Arctic Cyclone Activity and the Beaufort High
Publisher: American Meteorological Society
Nordic Seas Hydrography in the Context of Arctic and North Atlantic Ocean Dynamics
Publisher: American Meteorological Society
Double-Diffusive Recipes. Part II: Layer-Merging Events
Publisher: American Meteorological Society
Abstract: his study explores the dynamics of thermohaline staircases: well-defined stepped structures in temperature and salinity profiles, commonly observed in regions of active double diffusion. The evolution of staircases in time ...
Automated Ice-Tethered Profilers for Seawater Observations under Pack Ice in All Seasons
Publisher: American Meteorological Society
Abstract: An automated, easily deployed Ice-Tethered Profiler (ITP) instrument system, developed for deployment on perennial sea ice in the polar oceans to measure changes in upper ocean water properties in all seasons, is described, ...
Ice-Tethered Profiler Measurements of Dissolved Oxygen under Permanent Ice Cover in the Arctic Ocean
Publisher: American Meteorological Society
Abstract: Four ice-tethered profilers (ITPs), deployed between 2006 and 2009, have provided year-round dissolved oxygen (DO) measurements from the surface mixed layer to 760-m depth under the permanent sea ice cover in the Arctic ...
Deep-Water Flow over the Lomonosov Ridge in the Arctic Ocean
Publisher: American Meteorological Society
Abstract: The Arctic Ocean likely impacts global climate through its effect on the rate of deep-water formation and the subsequent influence on global thermohaline circulation. Here, the renewal of the deep waters in the isolated ...
