Wind Drift, Breakdown, and Pile Up of the Ice Field

Journal of Marine Science and Engineering, 2023
This article contains the analytical model of the drift of a separate ice field under the action of wind and current, in which velocities and directions can vary over time.

Mapping of sea ice and measurement of its drift using aircraft synthetic aperture radar images [PDF]

, 1979
Side-looking radar images of Arctic sea ice were obtained as part of the Arctic Ice Dynamics Joint Experiment. Repetitive coverages of a test site in the Arctic were used to measure sea ice drift, employing single images and blocks of overlapping radar ...

Improvement of Sea Ice Drift Extraction Based on Feature Tracking from C-SAR/01 Imagery

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
In this study, the extraction of sea ice drift from imagery captured by the 1-meter C-SAR 01 satellite (C-SAR/01) was facilitated utilizing the oriented fast and rotated brief algorithm within the feature tracking procedure, thus addressing the ...

Ice condensation as a planet formation mechanism [PDF]

, 2013
We show that condensation is an efficient particle growth mechanism, leading to growth beyond decimeter-sized pebbles close to an ice line in protoplanetary discs. As coagulation of dust particles is frustrated by bouncing and fragmentation, condensation

Arctic warming interrupts the Transpolar Drift and affects long-range transport of sea ice and ice-rafted matter

Scientific Reports, 2019
Sea ice is an important transport vehicle for gaseous, dissolved and particulate matter in the Arctic Ocean. Due to the recently observed acceleration in sea ice drift, it has been assumed that more matter is advected by the Transpolar Drift from shallow

Regional melt-pond fraction and albedo of thin Arctic first-year drift ice in late summer

, 2015
. The paper presents a case study of the regional (≈150 km) morphological and optical properties of a relatively thin, 70–90 cm modal thickness, first-year Arctic sea ice pack in an advanced stage of melt.

Antarctic ocean and sea ice response to ozone depletion: a two timescale problem [PDF]

, 2014
The response of the Southern Ocean to a repeating seasonal cycle of ozone loss is studied in two coupled climate models and found to comprise both fast and slow processes. The fast response is similar to the inter-annual signature of the Southern Annular

Linked trends in the South Pacific sea ice edge and Southern Oscillation Index [PDF]

, 2016
Previous work have shown that sea ice variability in the South Pacific is associated with extratropical atmospheric anomalies linked to the Southern Oscillation (SO).

An analytical model for wind-driven Arctic summer sea ice drift

, 2015
. The authors present an analytical model for wind-driven free drift of sea ice that allows for an arbitrary mixture of ice and open water. The model includes an ice–ocean boundary layer with an Ekman spiral, forced by transfers of wind-input momentum ...

Rapid Decline of Total Antarctic Sea Ice Extent during 2014–16 Controlled by Wind-Driven Sea Ice Drift

Journal of Climate, 2019
Between 2014 and 2016 the annual mean total extent of Antarctic sea ice decreased by a record, unprecedented amount of 1.6 × 106 km2, the largest in a record starting in the late 1970s. The mechanisms behind such a rapid decrease remain unknown.
