Evidence for a mid-Pleistocene change of ice-drift pattern in the Nordic seas [PDF]

, 2003
Sediment proxy records from a continuous, 1.5 million year long deep-sea sediment core from a site in the western Norwegian Sea were used to obtain new insights into the nature of palaeoceanographic change in the northern North Atlantic (Nordic seas ...

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

International 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.

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

Remote 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

Icebergs boost phytoplankton growth in the Southern Ocean [PDF]

, 2008
Icebergs which calve from the Antarctic ice shelves and drift in the Southern Ocean deliver fresh water, dust and minerogenic particles to the surface ocean along the iceberg's path.

Ocean processes at the Antarctic continental slope [PDF]

, 2014
The Antarctic continental shelves and slopes occupy relatively small areas, but, nevertheless, are important for global climate, biogeochemical cycling and ecosystem functioning.

Overview of molecular signatures of senescence and associated resources: pros and cons

FEBS Open Bio, EarlyView.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

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

Geo-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

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

The 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 ...

Tracking icebergs with time-lapse photography and sparse optical flow, LeConte Bay, Alaska, 2016–2017 [PDF]

, 2019
We present a workflow to track icebergs in proglacial fjords using oblique time-lapse photos and the Lucas-Kanade optical flow algorithm. We employ the workflow at LeConte Bay, Alaska, where we ran five time-lapse cameras between April 2016 and ...
