The observed decline in Arctic sea ice is projected to continue, opening shorter trade routes across the Arctic Ocean, with potentially global economic implications. Here we quantify, using Coupled Model Intercomparison Project Phase 5 global climate model simulations calibrated to remove spatial biases, how projected sea ice loss might increase opportunities for Arctic transit shipping. By mid...

The surface energy balance (SEB) is essential for understanding the coupled cryosphere-atmosphere system in the Arctic. In this study, we investigate the spatiotemporal variability in SEB across tundra, snow and ice. During the snow-free period, the main energy sink for ice sites is surface melt. For tundra, energy is used for sensible and latent heat flux and soil heat flux leading to permafro...

Liquid salty micro-channels (brine) between growing ice platelets in sea ice are an important habitat for CO2-binding microalgaea with great impact on polar ecosystems. The structure formation of ice platelets is microscopically described and a phase field model is developed. The pattern formation during solidification of the two-dimensional interstitial liquid is considered by two coupled orde...

Noble gas analysis can be performed on two types of ice core samples. First, atmospheric air, trapped in bubbles in polar ice, can be extracted and analyzed for its noble gas composition. Variations in the isotopic and elemental composition of noble gases reveal changes in the composition of the paleoatmosphere or the impact of climate-related physical processes acting when the air was enclosed...

yog-ice cream (frozen yogurt), is a kind of frozen dessert which has similar features to ice cream in physical and appearance characteristics. recently, there has been a growing interest in using frozen yogurt due to existence of lactic acid bacteria & fermentation processing. besides, yog-ice cream contains lower levels of sugar, fat & emulsifiers than ice cream. this research was conducted to...

there are many tests for diagnosis of myasthenia gravis including tensilon test and ice test.to compare the ice test with tensilon test in sub jects with myasthenic and nonmyasthenic ptosis a process research study was designed. this study was performed in patients complaining of acquired ptosis in the neuro-ophthalmology center of farabi hospital. all 156 patients were tested with ice pack and...

Sea ice plays an important role in the air–ice– ocean interaction, but it is often represented simply in many regional atmospheric models. The Noah sea ice scheme, which is the only option in the current Weather Research and Forecasting (WRF) model (version 3.6.1), has a problem of energy imbalance due to its simplification in snow processes and lack of ablation and accretion processes in ice. ...
