Regime Shift in Arctic Ocean Sea‐Ice Extent

open access: yesGeophysical Research Letters
A regime shift is an abrupt, substantial, and persistent change in the state of a system. We show that a regime shift in the September Arctic sea‐ice extent (SIE) occurred in 2007. Before 2007, September SIE was declining approximately linearly.

Sea ice index monitors polar ice extent [PDF]

open access: yesEos, Transactions American Geophysical Union, 2004
In September 2002, Arctic sea ice extent reached a minimum unprecedented in 24 years of satellite passive microwave observations, and almost certainly unmatched in 50 years of charting Arctic ice [Serreze et al., 2003]. Again, in September 2003, ice retreated to an unusually low extent, almost equaling the previous year's minimum (Figure l).

Simulating ice-shelf extent using damage mechanics

open access: yesJournal of Glaciology, 2022
Inaccurate representations of iceberg calving from ice shelves are a large source of uncertainty in mass-loss projections from the Antarctic ice sheet. Here, we address this limitation by implementing and testing a continuum damage-mechanics model in a ...

Changes of the Arctic marginal ice zone during the satellite era [PDF]

open access: yesThe Cryosphere, 2020
Many studies have shown a decrease in Arctic sea ice extent. It does not logically follow, however, that the extent of the marginal ice zone (MIZ), here defined as the area of the ocean with ice concentrations from 15 % to 80 %, is also ...

Simulating the Laurentide Ice Sheet of the Last Glacial Maximum [PDF]

open access: yesThe Cryosphere, 2023
In the last decades, great effort has been made to reconstruct the Laurentide Ice Sheet (LIS) during the Last Glacial Maximum (LGM; ca. 21 000 years before present, 21 kyr ago).

COASTAL DYNAMICS OF THE PECHORA AND KARA SEAS UNDER CHANGING CLIMATIC CONDITIONS AND HUMAN DISTURBANCES

open access: yesGeography, Environment, Sustainability, 2016
Coastal dynamics monitoring on the key areas of oil and gas development at the Barents and Kara Seas has been carried out by Laboratory of Geoecology of the North at the Faculty of Geography (Lomonosov Moscow State University) together with Zubov State ...

The Arctic sea ice cover of 2016: a year of record-low highs and higher-than-expected lows [PDF]

open access: yesThe Cryosphere, 2018
The Arctic sea ice cover of 2016 was highly noteworthy, as it featured record low monthly sea ice extents at the start of the year but a summer (September) extent that was higher than expected by most seasonal forecasts.

Spatial and Temporal Variations in the Extent and Thickness of Arctic Landfast Ice

open access: yesRemote Sensing, 2019
Analyses of landfast ice in Arctic coastal areas provide a comprehensive understanding of the variations in Arctic sea ice and generate data for studies on the utilization of the Arctic passages.

ANALYSIS OF INTERANNUAL AND SEASONAL VARIABILITY OF ICE COVER IN ANIVA BAY AND LA PEROUSE STRAIT ACCORDING TO EARTH REMOTE SENSING DATA

open access: yesInterCarto. InterGIS, 2017
Based on the data of satellite observations of the ice cover with the use of geoinformation technologies, an analysis of the interannual and seasonal variability of ice cover in Aniva Bay and La Perouse Strait has been made.

Inter-annual and geographical variations in the extent of bare ice and dark ice on the Greenland ice sheet derived from MODIS satellite images

open access: yesFrontiers in Earth Science, 2016
Areas of dark ice have appeared on the Greenland ice sheet every summer in recent years. These are likely to have a great impact on the mass balance of the ice sheet because of their low albedo.
