Relating arctic pack ice stress and deformation under winter conditions [PDF]
Journal of Geophysical Research: Oceans, 2002 Together, thermodynamic and dynamic processes determine the thickness distribution of the ice cover on polar oceans, which governs the exchange of energy between the atmosphere and the ocean. Key to the dynamic processes is the mechanical behavior of the ice cover. During the Surface Heat Budget of the Arctic Ocean (SHEBA) field experiment, we deployed

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.

Multiscale mushy layer model for Arctic marginal ice zone dynamics [PDF]
Scientific ReportsPerhaps the most dynamic component of the Arctic sea ice cover is the marginal ice zone (MIZ), the transitional region between dense pack ice to the north and open ocean to the south.

Transition in the fractal geometry of Arctic melt ponds [PDF]
The Cryosphere, 2012 During the Arctic melt season, the sea ice surface undergoes a remarkable transformation from vast expanses of snow covered ice to complex mosaics of ice and melt ponds.

The summer aerosol in the central Arctic 1991–2008: did it change or not? [PDF]
Atmospheric Chemistry and Physics, 2012 In the course of global warming dramatic changes are taking place in the Arctic and boreal environments. However, physical aerosol data in from the central summer Arctic taken over the course of 18 yr from 1991 to 2008 do not show systematic year-to-year

Oil tanker under ice loadings [PDF]
Scientific Reports, 2023 As a result of global warming, the area of the polar pack ice is diminishing, making merchant travel more practical. Even if Arctic ice thickness reduced in the summer, fractured ice is still presenting operational risks to the future navigation.

Winter sea ice export from the Laptev Sea preconditions the local summer sea ice cover and fast ice decay [PDF]
The Cryosphere, 2017 Ice retreat in the eastern Eurasian Arctic is a consequence of atmospheric and oceanic processes and regional feedback mechanisms acting on the ice cover, both in winter and summer.

Predominance of β‐proteobacteria in summer melt pools on Arctic pack ice [PDF]
Limnology and Oceanography, 2004 The diversity and community structure of bacteria in melt pools on Arctic pack ice floes were dominated by bproteobacteria. Thirty‐five percent of the pure cultures isolated in 1997 from pack ice floes north of Svalbard and in the Fram Strait were from the β‐proteobacteria group.

Floating ice-algal aggregates below melting arctic sea ice. [PDF]
PLoS ONE, 2013 During two consecutive cruises to the Eastern Central Arctic in late summer 2012, we observed floating algal aggregates in the melt-water layer below and between melting ice floes of first-year pack ice.
