A hybrid ice-mélange model based on particle and continuum methods [PDF]

open access: yesThe Cryosphere
Ice mélange, a composite of sea ice and icebergs, can have a major influence on sea-ice–ocean interactions. However, ice mélange has not been represented in climate models because numerically efficient realizations do not exist.

SAR Ship–Iceberg Discrimination in Arctic Conditions Using Deep Learning

open access: yesRemote Sensing, 2022
Maritime surveillance of the Arctic region is of growing importance as shipping, fishing and tourism are increasing due to the sea ice retreat caused by global warming. Ships that do not identify themselves with a transponder system, so-called dark ships,

Melting and fragmentation laws from the evolution of two large Southern Ocean icebergs estimated from satellite data [PDF]

open access: yesThe Cryosphere, 2018
The evolution of the thickness and area of two large Southern Ocean icebergs that have drifted in open water for more than a year is estimated through the combined analysis of altimeter data and visible satellite images.

Detailed Lacustrine Calving Iceberg Inventory from Very High Resolution Optical Imagery and Object-Based Image Analysis

open access: yesRemote Sensing, 2020
In the field of iceberg and glacier calving studies, it is important to collect comprehensive datasets of populations of icebergs. Particularly, calving of lake-terminating glaciers has been understudied.

Islands of Ice: Influence of Free-Drifting Antarctic Icebergs on Pelagic Marine Ecosystems [PDF]

open access: yesOceanography, 2012
Regional warming around West Antarctica, including the Antarctic Peninsula, is related to the retreat of glaciers that has resulted in significant ice mass loss in recent decades (De Angelis and Skvarca, 2003). Large icebergs (> 18.5 km long) originating

Impacts of tidewater glacier advance on iceberg habitat

open access: yesAnnals of Glaciology, 2023
Icebergs in proglacial fjords serve as pupping, resting and molting habitat for some of the largest seasonal aggregations of harbor seals (Phoca vitulina richardii) in Alaska.

Green Icebergs Revisited [PDF]

open access: yes, 2019
Ice crystals form in supercooled seawater beneath several Antarctic ice shelves; as they rise to the ice-shelf base they scavenge particles from the water and incorporate them into the growing basal ice.

Fragmentation patterns of Antarctic icebergs in sea ice: observations and statistical data

open access: yesInternational Journal of Digital Earth
Fragmentation is a key process in Antarctic iceberg decay, influencing the Antarctic climate and ecosystems. However, iceberg fragmentation has not been quantified at the pan-Antarctic scale.

Sub-grid parameterization of iceberg drag in a coupled iceberg–ocean model [PDF]

open access: yesThe Cryosphere
Ocean conditions in fjords play a key role in the accelerating ice mass loss of Greenland's marine-terminating glaciers. Ice mélange and icebergs have been shown to impact fjord circulation, heat and freshwater fluxes, and the submarine melting of ...
