An Elastic–Viscous–Plastic Model for Sea Ice Dynamics
Arctic Ice Dynamics Joint Experiment Parallel Ocean Program elastic–viscous–plastic
2008/11/26
The standard model for sea ice dynamics treats the ice pack as a visco–plastic material that flows plastically under typical stress conditions but behaves as a linear viscous fluid where strain rates ...
The Impact of Southern Ocean Sea Ice in a Global Ocean Model
Southern Ocean Global Ocean Model Sea Ice
2008/10/24
Most of the Southern Ocean (SO) is marginally stably stratified and thus prone to enhanced convection and possibly bottom-water formation whenever the upper ocean is cooled or made more saline by ice ...
Loss of Hyperbolicity and Ill-posedness of the Viscous–Plastic Sea Ice Rheology in Uniaxial Divergent Flow
Loss of Hyperbolicity Ill-posedness Viscous–Plastic Sea Ice Rheology Uniaxial Divergent Flow
2008/7/23
Local contact interactions between sea ice floes can be modeled on the large scale by treating the pack as a two-dimensional continuum with granular properties. One such model, which has gained promin...
Effects of Rheology and Ice Thickness Distribution in a Dynamic–Thermodynamic Sea Ice Model
Effects of Rheology Ice Thickness Distribution Dynamic–Thermodynamic Sea Ice Model
2008/7/22
Realistic treatment of sea ice processes in general circulation models is needed to simulate properly global climate and climate change scenarios. As new sea ice treatments become available, it is nec...
Slope-Enhanced Fission of Salty Hetons under Sea Ice
Slope-Enhanced Fission Salty Hetons Sea Ice
2008/7/3
Ocean responses to a single brine source under ice and over a sloping bottom are investigated in numerical experiments. Brine sources considered herein are often much stronger than that anticipated fr...
On the Role of Wind-Driven Sea Ice Motion on Ocean Ventilation
Wind-Driven Sea Ice Motion Ocean Ventilation
2008/6/26
Simulations with a coupled ocean–atmosphere–sea ice model are used to investigate the role of wind-driven sea ice motion on ocean ventilation. Two model experiments are analyzed in detail: one includi...
On the Role of Sea Ice and Convection in a Global Ocean Model
Role of Sea Ice Convection Global Ocean Model
2008/6/6
An earlier estimate regarding the possible impact of sea ice on deep-ocean water mass properties and the global thermohaline circulation in a coupled sea ice–ocean general circulation model (OGCM) is ...
Vitamin B12 and cobalt cycling among diatoms and bacteria in Antarctic sea ice microbial communities
Vitamin B12 cobalt cycling among diatoms
2014/4/21
Within McMurdo Sound’s annual sea ice, assimilation and concentrations of vitamin B12 (cobalamin),
microbial community productivity, and biomass were examined among three 100-m2
quadrats where light...
Biogeochemical composition of natural sea ice brines from the Weddell Sea during early austral summer
natural sea ice brines Biogeochemical composition
2014/4/22
Sea ice brines were collected from a single floe composed of different ice types in the western Weddell Sea in
December 2004. The chemical composition of the brines (temperature: 23.4uC to 22.1uC; sa...
