Phenological Changes and Driving Forces of Lake Ice in Central Asia from 2002 to 2020
Remote Sensing, 2022 Lake ice phenology is an indicator of past and present climate, it is sensitive to regional and global climate change. In the past few decades, the climate of Central Asia has changed significantly due to global warming and anthropogenic activities ...

The role of lake size and local phenomena for monitoring ground-fast lake ice. [PDF]
Int J Remote Sens, 2019 In this study, we assess the effect of the lake size on the accuracy of a threshold-based classification of ground-fast and floating lake ice from Sentinel-1 Synthetic Aperture Radar (SAR) imagery.

Lake Ice Detection from Sentinel-1 SAR with Deep Learning [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 . Lake ice, as part of the Essential Climate Variable (ECV) lakes, is an important indicator to monitor climate change and global warming. The spatio-temporal extent of lake ice cover, along with the timings of key phenological events such as freeze-up ...

Inter-annual variation in lake ice composition in the European Arctic: observations based on high-resolution thermistor strings [PDF]
Earth System Science Data, 2021 Climate change and global warming strongly impact the cryosphere. The rise of air temperature and change of precipitation patterns lead to dramatic responses of snow and ice heat and mass balance. Sustainable field observations on lake air–snow–ice–water

A stratigraphic link across 1100 km of the Antarctic Ice Sheet between the Vostok ice-core site and Titan Dome (near South Pole) [PDF]
, 2000 Isochronous internal ice-sheet layering, measured from airborne 60 MHz radar, was traced between Lake Vostok and the Titan Ice Dome (100 km from South Pole Station), Antarctica. Three layers were selected between Ridge B and Titan Dome, and between Ridge

Is Vostok lake in steady state? [PDF]
, 2004 Stable-isotope (D and 18O) data from the Vostok (East Antarctica) ice core are used to explore whether or not subglacial Vostok lake is in isotopic steady state. A simple box model shows that the lake is likely to be in steady state on time-scales of the

Lake ice ablation rates from permanently ice-covered Antarctic lakes [PDF]
Journal of Glaciology, 2013 AbstractIn the McMurdo Dry Valleys of Antarctica, three large, permanently ice-covered, closed-basin lakes exist along the floor of Taylor Valley. Lake ice ablation (loss of ice mass) is calculated as the sum of sublimation and surface melt, and is the driver of ice-cover turnover in these systems.

Reconstructing ice-sheet accumulation rates at ridge B, East Antarctica [PDF]
, 2004 Understanding how ice sheets responded to past climate change is fundamental to forecasting how they will respond in the future. Numerical models calculating the evolution of ice sheets depend upon accumulation data, which are principally available from ...

Star patterns on lake ice [PDF]
Physical Review E, 2007 Star patterns, reminiscent of a wide range of diffusively controlled growth forms from snowflakes to Saffman-Taylor fingers, are ubiquitous features of ice-covered lakes. Despite the commonality and beauty of these "lake stars," the underlying physical processes that produce them have not been explained in a coherent theoretical framework.
