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.

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

Estimation of the volume of icebergs calved from the outlet glaciers of the Severnaya Zemlya archipelago for 2014–2019

open access: yesЛëд и снег, 2021
Volume of icebergs calved from the output glaciers located on the Northern Land during 2014–2019 was estimated using the satellite information. High-resolution satellite data were obtained in the visible spectral range from the non-commercial satellites ...

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 ...

Satellite-Based Identification and Characterization of Extreme Ice Features: Hummocks and Ice Islands

open access: yesRemote Sensing, 2023
The satellite-based techniques for the monitoring of extreme ice features (EIFs) in the Canadian Arctic were investigated and demonstrated using synthetic aperture radar (SAR) and electro-optical data sources. The main EIF types include large ice islands

Extracting iceberg freeboard using shadow length in high-resolution optical images

open access: yesGeo-spatial Information Science
Icebergs are big chunks of ice floating on the ocean surface, and melting of icebergs contributes for the major part of freshwater flux into ocean. Dynamic monitoring of the icebergs in Antarctica and accurate estimation of their volume are important for

Estimation of potential fresh water reserves in icebergs

open access: yesЛëд и снег, 2017
According to the forecast of the global shortage of fresh water it is expected that the global demand for drink‑ ing water will be increased up to 400 km3 per a year. As the main potential resources of drinking water it is proposed to use table Antarctic

Significant contribution of small icebergs to the freshwater budget in Greenland fjords

open access: yesCommunications Earth & Environment, 2020
Small icebergs comprise a significant fraction of icebergs in Greenland fjords and have fallen below the detection and resolution limit of earlier satellite data, suggest analyses of high-resolution imagery with deep neural networks.

Iceberg influence on snow distribution and slush formation on Antarctic landfast sea ice from airborne multi-sensor observations [PDF]

open access: yesThe Cryosphere
Landfast sea ice fringes much of the coast of Antarctica and plays an important role for coastal ice–ocean–atmosphere interaction and ice shelf stability, as well as for the sea ice associated ecosystem.

First record of the occurrence of sea ice in the Cordillera Darwin fjords (54°S), Chile

open access: yesAnnals of Glaciology, 2020
This paper provides the first evidence for sea-ice formation in the Cordillera Darwin (CD) fjords in southern Chile, which is farther north than sea ice has previously been reported for the Southern Hemisphere.
