Laboratory Investigations of Iceberg Melting under Wave Conditions in Sea Water

Journal of Marine Science and Engineering
Changes in the masses of icebergs due to deterioration processes affect the drift of icebergs and should be taken into account when assessing iceberg risks in the areas of offshore development.

Icebergs, jigsaw puzzles, and genealogy: automated multi-generational iceberg tracking and lineage reconstruction [PDF]

The Cryosphere
Tabular icebergs calve from ice shelves and glaciers in Antarctica, Greenland, and northern Ellesmere Island. These “ice islands”, as they are referred to in the Arctic, drift, melt, and fragment, contributing freshwater and nutrients to the ocean ...

Semi-automated open water iceberg detection from Landsat applied to Disko Bay, West Greenland

Journal of Glaciology, 2019
Changes in Greenland's marine-terminating outlet glaciers have led to changes in the flux of icebergs into Greenland's coastal waters, yet icebergs remain a relatively understudied component of the ice-ocean system.

Analysis of Antarctic Peninsula glacier frontal ablation rates with respect to iceberg melt-inferred variability in ocean conditions

Journal of Glaciology, 2020
Marine-terminating glaciers on the Antarctic Peninsula (AP) have retreated, accelerated and thinned in response to climate change in recent decades. Ocean warming has been implicated as a trigger for these changes in glacier dynamics, yet little data ...

Machine Learning-Based Detection of Icebergs in Sea Ice and Open Water Using SAR Imagery

Remote Sensing
Icebergs pose significant risks to shipping, offshore oil exploration, and underwater pipelines. Detecting and monitoring icebergs in the North Atlantic Ocean, where darkness and cloud cover are frequent, is particularly challenging.

An equatorward force acting on large floating ice masses: Polfluchtkraft

Annals of Glaciology, 2017
This study reviews the effects of a force acting upon ice shelves and icebergs arising from the oblateness of the Earth's geoid and the displacement between the center of mass and the center of buoyancy for an object floating on water. The force has been

Detecting Arctic Icebergs in Sea Ice in L-Band SAR Images Using a Multiscale CFAR Algorithm

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This study proposes a multiscale extension of the well-known constant false alarm rate (CFAR) outlier detection method for the detection of icebergs in L-band synthetic aperture radar (SAR) images. The proposed method offers the possibility to accurately

Iron in Glacial Systems: Speciation, Reactivity, Freezing Behavior, and Alteration During Transport

Frontiers in Earth Science, 2018
A more insightful view of iron in glacial systems requires consideration of iron speciation and mineralogy, the potential for iron minerals to undergo weathering in ice-water environments, the impact of freezing on concentration and speciation, and ...

The use of the sonar complex when examining the lower surface of the ice

Российская Арктика, 2019
The article discusses the methodological issues of applying the sonar method to determine the shape of the lower surface of ice directly from the ice surface in the Arctic, as a complex solution for morphometric studies.

Tracking Holocene drift-ice limits on the northwest–southwest Iceland shelf: Comparing proxy data with observation and historical evidence

Arctic, Antarctic, and Alpine Research, 2019
We detail variations in the weight percent (wt%) of quartz, a proxy for drift ice, in fifteen marine sediment cores from the northwest, west, and southwest Iceland shelf throughout the past 10 cal ka BP.
