Arctic Ocean surface geostrophic circulation 2003–2014 [PDF]

The Cryosphere, 2017
Monitoring the surface circulation of the ice-covered Arctic Ocean is generally limited in space, time or both. We present a new 12-year record of geostrophic currents at monthly resolution in the ice-covered and ice-free Arctic Ocean derived from ...

Algal Hot Spots in a Changing Arctic Ocean: Sea-Ice Ridges and the Snow-Ice Interface

Frontiers in Marine Science, 2018
During the N-ICE2015 drift expedition north-west of Svalbard, we observed the establishment and development of algal communities in first-year ice (FYI) ridges and at the snow-ice interface.

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,

Low Density of Top Predators (Seabirds and Marine Mammals) in the High Arctic Pack Ice

Scientifica, 2016
The at-sea distribution of top predators, seabirds and marine mammals, was determined in the high Arctic pack ice on board the icebreaker RV Polarstern in July to September 2014. In total, 1,620 transect counts were realised, lasting 30 min each.

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.

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.

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 ...

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.

Estimation Method for Ice load of Managed Ice in an Oblique Condition

한국해양공학회지, 2018
Recently, as sea ice in the Arctic has been decreasing due to global warming, it has become easier to develop oil and gas resources buried in the Arctic region.
