Platelet Ice Under Arctic Pack Ice in Winter [PDF]

Geophysical Research Letters, 2020
AbstractThe formation of platelet ice is well known to occur under Antarctic sea ice, where subice platelet layers form from supercooled ice shelf water. In the Arctic, however, platelet ice formation has not been extensively observed, and its formation and morphology currently remain enigmatic.

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.

Single-particle characterization of the high-Arctic summertime aerosol [PDF]

Atmospheric Chemistry and Physics, 2014
Single-particle mass-spectrometric measurements were carried out in the high Arctic north of 80° during summer 2008. The campaign took place onboard the icebreaker Oden and was part of the Arctic Summer Cloud Ocean Study (ASCOS).

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.

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.

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

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.

Winter Sightings of Marine Mammals in Arctic Pack Ice [PDF]

ARCTIC, 1987
There is limited information about the winter distribution of some arctic marine mammals. In February-March 1976 six species of marine mammals were sighted in the pack ice of Baffin Bay and Davis Strait. Hooded seals were sighted along the ice edge in February, but in late March adults with pups were seen.
