Observations of Coherence Changes in C‐Band SAR Linked to Snow Thermodynamics and Wind Redistribution on First‐Year Sea Ice

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract We present novel observations of C‐band Synthetic Aperture Radar (SAR) coherence sensitivities and patterns for snow on first‐year sea ice (FYI) consistent with snow thermodynamics and wind redistribution. Wintertime SAR coherence and backscatter change observations of landfast FYI in Dease Strait, Nunavut, Canada are made using 12‐day repeat ...

Contributions of statistical modelling for the understanding of the nivo-glaciological dynamics of a small arctic glacial basin (Austre Lovén glacier, Spitsberg)

, 2021
Since the middle of the 19th century, the Earth has experienced a climate shift marked by a high rise in temperature (+ 0.85 °C over the period 1880-2012). The Arctic is the region of the world that is warming the most rapidly, at a rate of 2 to 3 times faster than the global average.

Interaction of two tributary glacier branches and implications for surge behavior [PDF]

, 2018
Thesis (M.S.) University of Alaska Fairbanks, 2018A glacier surge is a dynamic phenomenon where the glacier after a long period of quiescence, increases its velocities by up to two orders of magnitude.

Radar systems for a polar mission, volume 3, appendices A-D, S, T [PDF]

Success is reported in the radar monitoring of such features of sea ice as concentration, floe size, leads and other water openings, drift, topographic features such as pressure ridges and hummocks, fractures, and a qualitative indication of age and ...

Exploring canyons beneath Devon Ice Cap for sub-glacial drainage using radar and thermodynamic modeling

Journal of Glaciology
Sub-glacial canyon features up to 580 m deep between flat terraces were identified beneath Devon Ice Cap during a 2023 radar echo sounding (RES) survey.

Japanese glaciological activities in the Arctic region (report)

Japanese glaciological activities in the Arctic region (report)
P(論文) The objectives of the Japanese Arctic Glaciological Expedition were to study the regional characteristics of glacier processes and the climatic and environmental changes for the last few hundred years in the Arctic cryosphere. During 1987-1996,glaciological observation and shallow ice core drilling were carried out at various places such as the ...
