Longer thaw seasons increase nitrogen availability for leaching during fall in tundra soils [PDF]

open access: yes, 2016
Climate change has resulted in warmer soil temperatures, earlier spring thaw and later fall freeze-up, resulting in warmer soil temperatures and thawing of permafrost in tundra regions.

Unidirectional freeze casting of compressible metallic aerogel composed of freeze-dried cellulose nanofibers and silver nanowires

open access: yesMicro and Nano Systems Letters, 2023
Metallic aerogels have attracted tremendous interest because of their superior properties, such as low density, high electrical conductivity, and large specific surface area. However, extremely brittle connections in their 3D networks remain a challenge.

Comprehensive two-dimensional river ice model based on boundary-fitted coordinate transformation method

open access: yesWater Science and Engineering, 2014
River ice is a natural phenomenon in cold regions, influenced by meteorology, geomorphology, and hydraulic conditions. River ice processes involve complex interactions between hydrodynamic, mechanical, and thermal processes, and they are also influenced ...

Monitoring the Ice Phenology of Qinghai Lake from 1980 to 2018 Using Multisource Remote Sensing Data and Google Earth Engine

open access: yesRemote Sensing, 2020
Lake ice, one of the most direct lake physical characteristics affected by climate change, can reflect small-scale environmental changes caused by the atmosphere and hydrology, as well as large-scale climate changes such as global warming.

Water Discharge Measurement by ADCP During Freeze-up Period

open access: yesThe Bulletin of Irkutsk State University. Series Earth Sciences, 2022
As a part of the modernization of the national hydrological network, a large number of ADCPs were delivered to the stream-gaging stations of the Roshydromet and, as a rule, used only during the open channel period. At the same time, the measurement of water discharge during the freeze-up period has always been a laborious, technically complex task, and

Evolution From Past to Future Conditions of Fast Ice Coverage in James Bay

open access: yesFrontiers in Earth Science, 2019
Fast ice is often used by coastal communities in the James Bay area for transportation in winter using snowmobiles. Therefore, the extent of fast ice along the James Bay coastline is important for land use and any changes to these extents may have ...

Scalable anisotropic cooling aerogels by additive freeze-casting

open access: yesNature Communications, 2022
Scaling up anisotropic freeze-casting processes can be challenging due to the temperature gradient farther from the cold source. Here, authors report an additive freeze-casting technique able to produce large-scale aerogel panels and demonstrate it ...
