aSpire The amundsen Sea polynya international research expedition
international research expedition Sea
2015/7/15
In search of an explanation for some of the greenest waters ever seen
in coastal Antarctica and their possible link to some of the fastest melting glaciers
and declining summer sea ice, the Amunds...
On the Development and Cause of the Weddell Polynya in a Sea Ice Simulation
Weddell Polynya Sea Ice Simulation
2009/2/5
Occurrence of the Weddell polynya, a large open-water area in the midst of the wintertime pack ice of the southern ocean, is examined through a sequence of numerical simulations of the sea ice cover. ...
A Mechanism for the Formation of the Weddell Polynya in 1974
Weddell Polynya high-salinity mixed layer
2009/1/9
The formation of the Weddell Polynya is investigated with a one-dimensional, convective mixed-layer model, using in situ data from late summer 1974 as initial conditions. We propose that a high-salini...
A Time-Dependent Model of a Coastal Polynya
Time-Dependent Model Coastal Polynya offshore wind
2009/1/5
An idealized model is used here to examine the temporal behavior of a coastal polynya driven by an offshore wind. The model has incorporated the important effect of a finite surface dift by which the ...
A Latent-and Sensible-Heat Polynya Model for the North Water, Northern Baffin Bay
North Water A Latent-and Sensible-Heat Polynya Northern Baffin Bay
2008/12/22
The Pease latent-heat polynya model is coupled to a reduced-gravity, coastal upwelling model in order to simulate the formation and maintenance of the North Water (NOW), the Arctic's largest polynya, ...
A Nonlinear Steady-State Model of the North Water Polynya, Baffin Bay
North Water Nonlinear Steady-State Model
2008/12/15
A nonlinear, steady-state model of the North Water (NOW), the Arctic's largest polynya, is presented. The model follows in the spirit of the recently developed latent and sensible heat polynya model o...
A Model for the Influence of Wind and Oceanic Currents on the Size of a Steady-State Latent Heat Coastal Polynya
Northeast Water polynya Influence of Wind Oceanic Currents
2008/12/3
This paper presents a model for determining the size and shape of a steady-state latent heat coastal polynya in terms of the following free parameters: 1) the frazil ice production rate (F); 2) the wi...

North Wate Northeast Water polynya
2008/11/26
This paper presents a model for determining the size and shape of a steady-state latent heat coastal polynya in terms of the following free parameters: 1) the frazil ice production rate (F); 2) the ...
Shallow Convection and Buoyancy Equilibration in an Idealized Coastal Polynya
Shallow Convection Buoyancy Equilibration Idealized Coastal Polynya
2008/11/17
The recent theoretical approach of Visbeck, Marshall, and Jones is used to examine shallow convection and offshore transport of dense water from an idealized coastal polynya. A constant negative buoya...
Formation and Maintenance of a Polynya in the Weddell Sea
Formation Maintenance Polynya Weddell Sea
2008/7/11
A dynamic–thermodynamic sea ice–mixed layer model for the Weddell Sea is complemented by a simple, diagnostic model to account for local sea ice–atmosphere interaction. To consider the atmospheric inf...
Dense Water Formation beneath a Time-Dependent Coastal Polynya
Dense Water Formation Time-Dependent Coastal Polynya
2008/7/10
Recent modeling studies of dense water formation beneath an idealized steady coastal polynya have provided simple analytical expressions for the maximum density anomaly achievable as a function of the...
A Two-Dimensional Time-Dependent Model of a Wind-Driven Coastal Polynya: Application to the St. Lawrence Island Polynya
A Two-Dimensional Time-Dependent Model Wind-Driven Coastal Polynya St. Lawrence Island Polynya
2008/6/30
A two-dimensional time-dependent model of a wind-driven coastal polynya is presented. The model combines and extends previous one-dimensional time-dependent and two-dimensional steady-state flux formu...
A Reconstruction of the Air–Sea Interaction Associated with the Weddell Polynya
Reconstruction Air–Sea Interaction Associated Weddell Polynya
2008/6/9
A recent major climatic event was the occurrence of approximately 350 000 square kilometers of open water in the normally ice covered Weddell Sea near Antarctica during the winters of 1974–76. Within ...
