Microwave signatures of first-year and multiyear sea ice [PDF]
Journal of Geophysical Research, 1973 A combination of remote sensing from an aircraft and simultaneous surface measurements have confirmed the feasibility of identifying old and new sea ice according to its emission of thermal radiation at wavelengths between 0.3 and 3 cm. Emissivity of first-year thick ice with a surface temperature of about 260 K is 0.95 or greater for wavelengths ...

Annals of Glaciology, 2020 The evolution of melt ponds on Arctic sea ice in summer is one of the main factors that affect sea-ice albedo and hence the polar climate system. Due to the different spectral properties of open water, melt pond and sea ice, the melt pond fraction (MPF ...

Evidence of recent changes in the ice regime of lakes in the Canadian High Arctic from spaceborne satellite observations [PDF]
The Cryosphere, 2016 Arctic lakes, through their ice cover phenology, are a key indicator of climatic changes that the high-latitude environment is experiencing. In the case of lakes in the Canadian Arctic Archipelago (CAA), many of which are ice covered more than 10 months ...

Frontiers in Marine Science, 2020 The large declines in Arctic sea-ice age and extent over the last decades could have altered the diversity of sea-ice associated unicellular eukaryotes (referred to as sea-ice protists). A time series from the Russian ice-drift stations from the 1980s to

Multiyear Arctic Sea Ice Classification Using QuikSCAT
IEEE Transactions on Geoscience and Remote Sensing, 2012 Long-term trends in Arctic sea ice are of particular interest in studies of global temperature, climate change, and industrial application. This paper analyzes intra-annual and interannual trends in Ku-band backscatter over first-year (FY) and multiyear (MY) sea ice to develop a new sea-ice-type classification method.

Natural phenomena of endogenic origin in the Arctic basin
Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2020 The results of the study of the influence of the deep factor on the process of melting of the ice cover of the Arctic Ocean and the formation of dangerous natural phenomena are presented.

Basal control of supraglacial meltwater catchments on the Greenland Ice Sheet [PDF]
The Cryosphere, 2018 Ice surface topography controls the routing of surface meltwater generated in the ablation zones of glaciers and ice sheets. Meltwater routing is a direct source of ice mass loss as well as a primary influence on subglacial hydrology and basal sliding

Environmental Research Letters, 2022 The satellite-observed sea ice thickness (SIT) records from 2003 to 2020 identify an extreme SIT loss during 2010–2011. Ice thickness budget analysis demonstrates that the thickness loss was associated with an extraordinarily large multiyear ice (MYI ...

A comprehensive dataset of microbial abundance, dissolved organic carbon, and nitrogen in Tibetan Plateau glaciers [PDF]
Earth System Science Data, 2022 Glaciers are recognized as a biome dominated by microorganisms and a reservoir of organic carbon and nutrients. Global warming remarkably increases glacier melting rate and runoff volume, which have significant impacts on the carbon and nitrogen cycles ...

Assessing sea ice microwave emissivity up to submillimeter waves from airborne and satellite observations [PDF]
The CryosphereUpcoming submillimeter wave satellite missions require an improved understanding of sea ice emissivity to separate atmospheric and surface microwave signals under dry polar conditions.
