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 ...
High-resolution ice nucleation spectra of sea-ice bacteria:implications for cloud formation and life in frozen environments
High-resolution ice nucleation spectra sea-ice bacteria cloud formation
2010/1/15
Even though studies of Arctic ice forming particles suggest that a bacterial or viral source derived from open leads could be important for ice formation in Arctic clouds (Bigg and Leck, 2001), the ic...
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...
November 24, 2006，The occasional skua swooping around McMurdo Station scavenging for food, or the odd seal lounging next to a crack in the sea ice, is generally the only reminder for many here that th...
