Representing icebergs in the iLOVECLIM model (version 1.0) – a sensitivity study [PDF]

Geoscientific Model Development, 2015
Recent modelling studies have indicated that icebergs play an active role in the climate system as they interact with the ocean and the atmosphere. The icebergs' impact is due to their slowly released meltwater, which freshens and cools the ocean and ...

Antarctic iceberg distribution revealed through three decades of systematic ship-based observations in the SCAR International Iceberg Database

Journal of Glaciology, 2023
In 1981, the Scientific Committee on Antarctic Research endorsed a program for ship-based collection of Antarctic iceberg data, to be coordinated by the Norwegian Polar Institute (NPI).

Quad-Polarimetric Multi-Scale Analysis of Icebergs in ALOS-2 SAR Data: A Comparison between Icebergs in West and East Greenland

Remote Sensing, 2020
Icebergs are ocean hazards which require extensive monitoring. Synthetic Aperture Radar (SAR) satellites can help with this, however, SAR backscattering is strongly influenced by the properties of icebergs, together with meteorological and environmental ...

Weddell Sea iceberg drift: Five years of observations [PDF]

, 2006
Since 1999, 52 icebergs have been tagged with GPS buoys in the Weddell Seato enable monitoring of their position. The chosen icebergs were of small tomedium size, with a few icebergs larger than 10 km associatedwith the calving of icebergs A38 and A43 ...

Impact of icebergs on the seasonal submarine melt of Sermeq Kujalleq [PDF]

The Cryosphere, 2023
The role of icebergs in narrow fjords hosting marine-terminating glaciers in Greenland is poorly understood, even though iceberg melt results in a substantial freshwater flux that can exceed the subglacial discharge.

The origin of green icebergs in Antarctica [PDF]

, 1992
A comparison of samples from a translucent green iceberg with a core from the Ronne Ice Shelf revealed an excellent agreement in isotopic composition, crystal structure, and incorporated sediment particles.

Geographical distribution and volume of Antarctic icebergs derived from ship observation data

Annals of Glaciology, 2017
Information on the occurrence, spatial distribution and morphometric characteristics of Antarctic icebergs is needed in a large number of applications including navigation, heat and freshwater balance calculations, biochemistry of the ocean and ...

Icebergs in the North Atlantic: Modelling circulation changes and glacio-marine deposition [PDF]

, 1999
In order to investigate meltwater events in the North Atlantic, a simple iceberg generation, drift, and melting routine was implemented in a high-resolution OGCM.

Impact of icebergs on net primary productivity in the Southern Ocean [PDF]

The Cryosphere, 2017
Productivity in the Southern Ocean (SO) is iron-limited, and supply of iron dissolved from aeolian dust is believed to be the main source from outside the marine environment. However, recent studies show that icebergs could provide a comparable amount of
