Performance evaluation of quad-pol data compare to dual-pol SAR data for river ice classification

open access: yesEuropean Journal of Remote Sensing, 2019
Satellite SAR data are a unique source of information about river ice since the microwaves penetrate through clouds as well as snow and ice cover. The influence of the number of polarization channels on the nature and amount of information is, however ...

Use of Ice Covers for Transportation

open access: yesCanadian Geotechnical Journal, 1971
Observations are reported on the failure and use of freshwater ice covers for vehicular traffic. The study showed that good quality ice covers can support loads of up to P = 250 h2, where P is the total load in pounds and h is the thickness of the ice in inches. Failures were reported, however, for loadings as low as P = 50 h2. Factors contributing to

Antarctic Glacial and Subglacial Topography [PDF]

open access: yes, 1967
1. The data is collected and generalized according to 48,000km of surface traverses in Antarctica during the last 15 years. An evaluation is made of reliability of material and methods of study of the ice cover thickness, evaluation of precision of ...

Ice cover loss and debris cover evolution in the Afghanistan Hindu Kush Himalaya between 2000 and 2020

open access: yesArctic, Antarctic, and Alpine Research
Glaciers in Afghanistan are crucial elements for water resource and summer river flows. They are also threatened by rapid climate warming. This study presents an up-to-date assessment of ice cover loss for the entire country over two periods, 2000–2008 ...

Characteristics and growth processes of sea ice in Lutzow-Holm Bay

open access: yesAntarctic Record, 1997
Observations of multiyear land fast sea ice were made in Lutzow-Holm Bay, Antarctica over a period of two years from 1990 to 1991 to determine the snow and ice characteristics and ice growth prowth processes.

SEASONAL VARIABILITY OF CENTRAL ARCTIC OCEAN SEA-ICE COVER: NEW BIOMARKER (IP25 AND PIP25) DATA FROM SEDIMENT TRAPS DEPLOYED ON SOUTHERN LOMONOSOV RIDGE [PDF]

open access: yes, 2012
During the Polarstern 1995 Expedition, a long-term mooring system with two cone-shaped multi-sampling traps was deployed at the dominantly ice-covered western slope of the southern Lomonosov Ridge (81°04.5'N, 138°54.0'E, 1712 m water depth). One trap was

Sea ice trends in climate models only accurate in runs with biased global warming

open access: yes, 2017
Observations indicate that the Arctic sea ice cover is rapidly retreating while the Antarctic sea ice cover is steadily expanding. State-of-the-art climate models, by contrast, typically simulate a moderate decrease in both the Arctic and Antarctic sea ...
