Rotten ice is a loose term for ice that is melting or structurally disintegrating due to being honeycombed [1] by liquid water, air, or contaminants trapped between the initial growth of ice crystals. It may appear transparent or splotchy grey, and it is generally found after spring or summer thaws, presenting a danger to those traveling or ...

The response of Arctic sea ice to a warming climate includes decreases in extent, lower ice concentration, and reduced ice thickness. Summer melt seasons are lengthening with earlier melt onsets and later autumn freezeups. We believe this will likely lead to an increase in so-called “rotten ice” in the Arctic at the end of summer.

2016年1月1日 · Rotten ice is approximately isothermal, largely drained of brine, and is characterized by the presence of large multi-cm-scale brine channels that contribute to its very high permeability and low...

Thinning of the ice layer is caused by heat transfer and by melting at the top or bottom surface (or both). Deterioration, sometimes called rotting or candling because of the similarity of deteriorating ice crystals to an assembly of closely packed candles, is caused by the absorption of …

Ice sampled in mid-July in both 2015 and 2017 was found to be in various stages of rot. Ice sampled from thick floes was similar in character to the June 2015 and 3 July 2015 ice in non-ponded regions, but distinctly rotten below melt ponds. Uniformly thin floes were rotten throughout in both ponded and non-ponded regions.

2019年4月11日 · In Bethel, Alaska, record warm temperatures mean a frozen river that serves as an ice road is melting early. That's been deadly for some, and is leaving others unable to travel.

Rotting Ice? Ice rots in the spring. What does it look like? Rotting ice begins to look grey and splotchy. Stay off ice if you see: • Water on it • Slush • Cracks/holes • Grey/dirty veins Clear blue or green ice is the minimum standard for new and strong ice. White ice has air or snow in it and shouldn’t be considered strong.

2019年4月25日 · Temperatures have been been very warm over most of Alaska, encouraging what researchers call a “thermal” breakup, during which ice rots and rivers flow on to the sea with little drama. “Dynamic” breakups happen when spring temperatures stay cool until they suddenly warm, flushing snowmelt onto river ice.
