Taking stock of arctic sea ice and climate [PDF]

, 2009
The relationship among the cause-and-effect of the Arctic atmosphere, sea ice, and ocean is discussed. The increased vulnerability of the Arctic system to anomalous atmospheric forcing can be argued from the perspective that recent ice loss is the result

The effect of sea-ice parameterizations on the simulation of the Arctic ice pack [PDF]

Annals of Glaciology, 1997
A one-dimensional (1-D), thermodynamic sea-ice model with parameterized ice dynamics is coupled to a mixed-layer ocean model and driven with prescribed atmospheric forcings for the central Arctic.

sea-ice arching and multiple flow States of Arctic pack ice [PDF]

Annals of Glaciology, 2006
AbstractFlow of ice through narrow channels is Significantly affected by the amount of Shear Strength in plastic rheologies used in Sea-ice models as well as in reality. When thermodynamics is added to this problem, the capability of multiple flow States for the Same forcing through narrow passages arises.

The Arctic Summer Cloud Ocean Study (ASCOS): overview and experimental design [PDF]

Atmospheric Chemistry and Physics, 2014
The climate in the Arctic is changing faster than anywhere else on earth. Poorly understood feedback processes relating to Arctic clouds and aerosol–cloud interactions contribute to a poor understanding of the present changes in the Arctic climate system,

Cloud and boundary layer interactions over the Arctic sea ice in late summer [PDF]

, 2013
Observations from the Arctic Summer Cloud Ocean Study (ASCOS), in the central Arctic sea-ice pack in late summer 2008, provide a detailed view of cloud- atmosphere-surface interactions and vertical mixing processes over the sea-ice environment ...

Assessing the representation of Arctic sea ice and the marginal ice zone in ocean–sea ice reanalyses [PDF]

The Cryosphere
The recent development of data-assimilating reanalyses of the global ocean and sea ice enables a better understanding of the polar region dynamics and provides gridded descriptions of sea ice variables without temporal and spatial gaps.

Arctic marginal ice zone interannual variability and change point detection using two definitions (1983–2022)

Environmental Research Letters, 2023
The ongoing decline in Arctic sea ice extent and thickness underscores the scientific significance of monitoring the marginal ice zone (MIZ), a transitional region between the open ocean and pack ice.

Physical properties of the arctic summer aerosol particles in relation to sources at Ny-Alesund, Svalbard [PDF]

, 2014
Measurements of the number concentration and size distribution of aerosol particles in the size range of 0.5-20 μm diameter were made with an aerodynamic particle sizer at an Arctic site at Ny-Alesund, Svalbard in August-September 2007 during the ...

Hydraulic controls of summer Arctic pack ice albedo [PDF]

Journal of Geophysical Research: Oceans, 2004
Linkages between albedo, surface morphology, melt pond distribution, and properties of first‐year and multiyear sea ice have been studied at two field sites in the North American Arctic between 1998 and 2001. It is shown that summer sea‐ice albedo depends critically on surface melt‐pond hydrology, controlled by melt rate, ice permeability, and ...
