Impact of Variable Atmospheric and Oceanic Form Drag on Simulations of Arctic Sea Ice [PDF]

, 2014
Over Arctic sea ice, pressure ridges and floe and melt pond edges all introduce discrete obstructions to the flow of air or water past the ice and are a source of form drag.

A Submarine Sonar Study of Arctic Pack Ice [PDF]

Journal of Glaciology, 1975
AbstractA continuous profile of the Arctic Ocean ice canopy from Spitsbergen to the North Pole was made with 48 kHz echo sounders mourned on a nuclear submarine. A semi-automatic digitizer was used to measure coordinates from the records at a frequency of about 1 000 points per linear kilometre of track.

Climate change and ice hazards in the Beaufort Sea

Elementa: Science of the Anthropocene, 2014
Recent reductions in the summer extent of sea ice have focused the world’s attention on the effects of climate change. Increased CO2-derived global warming is rapidly shrinking the Arctic multi-year ice pack.

SASIEv.1: a framework for seasonal and multi-centennial Arctic sea ice emulation [PDF]

Geoscientific Model Development
The high computational expense of complex climate models and their tendency to underestimate observational records of Arctic sea ice sensitivity to anthropogenic forcers challenge our ability to assess the magnitude of forcing that will cause Arctic sea ...

Toward a marginal Arctic sea ice cover: changes to freezing, melting and dynamics [PDF]

The Cryosphere
As the summer Arctic sea ice extent has retreated, the marginal ice zone (MIZ) has been widening. The MIZ is defined as the region of the ice cover that is influenced by waves and for convenience here is defined as the region of the ice cover between sea

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 ...

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,

The progress in the study of Arctic pack ice ecology [PDF]

, 2004
The sea ice community plays an important role in the Arctic marine ecosystem. Because of the predicted environmental changes in the Arctic environment and specifically related to sea ice, the Arctic pack ice biota has received more attention in recent ...

CO2 flux over young and snow-covered Arctic pack ice in winter and spring [PDF]

, 2018
Rare CO2 flux measurements from Arctic pack ice show that two types of ice contribute to the release of CO2 from the ice to the atmosphere during winter and spring: young, thin ice with a thin layer of snow and older (several weeks), thicker ice with ...
