The presence of ice in soil dramatically alters soil hydrologic and thermal properties. Despite this important role, many recent studies show that explicitly including the hydrologic effects of soil ice in land surface models degrades the simulation of runoff in cold regions. This paper addresses this dilemma by employing the Community Land Model version 2.0 (CLM2.0) developed at the National C...

A distributed system of protection and diagnostics of support structural elements of high-voltage power lines (HVPL) on 500 kV voltage was developed at Karaganda State technical university: current monitoring of leakage currents of bunches of suspension insulators; detection ice-rime depositions; cathode protection of underground elements of support constructions; information transfer from the ...

Integrating renewable energy and storage systems provides a way of operating the electrical grid system more efficiently stably. Thermal batteries are most common devices for integration. However, it is not clear which integrated performs better in terms overall economics. Ice has low initial maintenance costs, but there an efficiency penalty charging can only shift loads associated with buildi...

We present a novel noninvasive technology for quality control in biobanking. We implemented a contactless optical in situ method with a remote detection unit. The method detects physical and chemical changes by emission spectroscopy. In the present study, ice formation in a vitrified sample is revealed by Raman scattering. The technology allows us to monitor sample quality during cold storage a...

Ice-wedge polygons and related microtopographic variations are ubiquitous to landscapes underlain by permafrost. Highand low-centered polygons are typical but surprisingly, their role on hydrologic fluxes and stocks is not well quantified. We performed hydrologic modeling analyses using the physically-based model WaSiM-ETH that was forced by data from the Biocomplexity Experiment, Barrow, Alask...

Considering the Arctic Ocean (including sea ice) as a defined volume, we develop equations describing the time-varying fluxes of mass, heat and freshwater (FW) into, and storage of those quantities within, that volume. The seasonal cycles of fluxes and storage of mass, heat and FW are quantified and illustrated using output from a numerical model. The meanings of 'reference values' and FW fluxe...
