The availability of real-time information on sea ice conditions in ice covered seas has always been important, not only to strategic military operations, but to the economies of those countries that b...
Hovercraft as a Mobile Science Platform Over Sea Ice in the Arctic Ocean
Arctic Ocean Science Platform Over Sea Ice
2015/7/17
Physical sampling of sea ice, the water mass, and subbottom geology in the Arctic Ocean is carried out from icebreakers or temporary ice camps deployed and supported by aircraft. Here, we consider an ...
Warm Arctic, Cold Continents: A Common Pattern Related to Arctic Sea Ice Melt, Snow Advance, and Extreme Winter Weather
Arctic sea ice statistical model the Eurasian snow winter temperatures
2015/7/16
Arctic sea ice was observed to be at a new record minimum in September 2012. Following this summer minimum, northern Eurasia and much of North America experienced severe winter weather during the wint...
Sea Ice Monitoring by Synthetic Aperture Radar
Sea Ice Monitoring Synthetic Aperture Radar
2015/7/16
Satellite-borne synthetic aperture radar (SAR) data are highly valuable not only for observing the open ocean but also for monitoring seasonally or permanently ice-covered ocean regions in the Arctic,...
Melting Ice:What is Happening to Arctic Sea Ice,and What Does It Mean for Us?
Melting Ice Arctic Sea Ice What Does It Mean for Us
2015/7/16
Sea ice has emerged as the canary in the coal mine of climate change. Its summer extent in the Arctic has decreased by about 50% over the past decade, and the Arctic Ocean has undergone a regime shift...
how is sediment transported to the seafloor
along coastlines where the sea ice rarely
melts? Are there distinctive characteristics
of the resulting deposits that label them as
accumulating in ...
As the world’s ice diminishes in the face of climate change—from the
dramatic decline in Arctic sea ice, to thinning at the margins of both the Greenland
and Antarctic ice sheets, to retreating mo...
A skill assessment of the biogeochemical model REcoM2 coupled to the Finite Element Sea Ice朞cean Model (FESOM 1.3)
biogeochemical model REcoM2 Finite Element Sea Ice朞cean Model
2014/12/19
In coupled biogeochmical杘cean models, the choice of numerical schemes in the ocean circulation component can have a large influence on the distribution of the biological tracers. Biogeochemical...
The Finite Element Sea Ice-Ocean Model (FESOM) v.1.4: formulation of an ocean general circulation model
Finite element model of sea Ice - Ocean global Ocean circulation patterns climate sensitivity experiments
2014/12/18
The Finite Element Sea Ice-Ocean Model (FESOM) is the first global ocean general circulation model based on unstructured-mesh methods that has been developed for the purpose of climate research. The a...
Better constraints on the sea-ice state using global sea-ice data assimilation
Better constraints sea-ice state global sea-ice data assimilation
2014/12/10
Short-term and decadal sea-ice prediction systems need a realistic initial state, generally obtained using ice–ocean model simulations with data assimilation. However, only sea-ice concentration and v...

Diatoms as Recorders of Sea Ice in the Bering and Chukchi Seas: Proxy Development and Application
Bering Sea Diatoms IP25 Marine Isotope Stage 11 Pacific Decadal Oscillation Sea Ice
2014/10/22
The recent, rapid decline in Arctic summer sea ice extent has prompted questions as to the rates and magnitude of previous sea ice decline and the affect of this physical change on icerelated ecosyste...
IP25: A Molecular Proxy of Sea-ice Duration in the Bering and Chukchi Seas
IP25 A Molecular Proxy Sea-ice Duration Bering Chukchi Seas
2014/10/21
Seasonal sea ice is an important component of the global climate system. Sea ice influences exchange rates of heat, moisture, and gas between the ocean and atmosphere. Sea ice also plays critical role...
Identifying variable sea ice carbon contributions to the Arctic ecosystem: A case study using highly branched isoprenoid lipid biomarkers in Cumberland Sound ringed seals
Sea ice carbon The arctic ecosystem
2014/10/16
We analyzed liver samples from 322 ringed seals (Pusa hispida) collected from Cumberland Sound (southeast
Baffin Island) to test our ability to differentiate between carbon sources in near apex preda...
Biological- and physical-induced oxygen dynamics in melting sea ice of the Fram Strait
Biological- and physical-induced oxygen dynamics melting sea ice Fram Strait
2014/7/10
We investigated the production, consumption, and exchange of O2 in melting sea ice to assess the biological- and physical-induced O2 turnover. The underside of the ice was covered with 5–20 cm3 large,...
