Potential source regions and processes of aerosol in the summer Arctic [PDF]

Atmospheric Chemistry and Physics, 2015
Sub-micrometer particle size distributions measured during four summer cruises of the Swedish icebreaker Oden 1991, 1996, 2001, and 2008 were combined with dimethyl sulfide gas data, back trajectories, and daily maps of pack ice cover in order to ...

Studies of the Mass Budget of Arctic Pack-Ice Floes [PDF]

Journal of Glaciology, 1965
AbstractThe processes of melting, freezing, precipitation, evaporation and condensation were considered in the computation of the mass budget of an ice floe in the northern Chukchi Sea. It was bound that condensation and evaporation contribute negligible amounts, and that melting accounted for the largest loss from the upper surface of the floe.

Status and trends in the structure of Arctic benthic food webs [PDF]

Polar Research, 2015
Ongoing climate warming is causing a dramatic loss of sea ice in the Arctic Ocean, and it is projected that the Arctic Ocean will become seasonally ice-free by 2040.

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.

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 ...

On the relationship between local stresses and strains in Arctic pack ice [PDF]

Annals of Glaciology, 1991
Local ice strains and in situ ice stresses were simultaneously measured on the Coordinated Eastern Arctic Experiment (CEAREX). The experiment took place in the fall of 1988 and was centered about an ice-strengthened ship moored to a multi-year floe in the pack ice northeast of Spitsbergen. During the period of data collection, which extended from early

The operational determination of wind stress on the Arctic ice pack

, 1977
Abstract : The performance of routine FNWC sea level pressure analyses and forecasts in the Beaufort Sea is evaluated for driving an ice model. The geostrophic winds determined from the FNWC pressure fields are compared to geostrophic winds determined from the AIDJEX experiment observations.

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.

Ice-tethered observational platforms in the Arctic Ocean pack ice

IFAC-PapersOnLine, 2016
Abstract: The Arctic Ocean faces rapid climate change, which impacts both physical and biological components of the marine ecosystem. Due to complicated and costly logistics inherent to sampling ice-covered areas, most studies conducted in the Arctic are based on relatively short-term sampling (weeks to months) centered around the minimum ice season.
