Exceptional snow accumulation in Svalbard this season, combined with unusually mild temperatures, highlights the shift from a cold–dry to a warm–wet Arctic climate regime. Deep loose snow (>1 m) is extremely difficult for snowmobile travel, especially with heavy sleds. #ClimateChange #ArcticResearch

Ursula E @ursenz.bsky.social · 23/02/2026

Looped moraines, also called surge or loop moraines, typically form on surging glaciers due to differential ice flow rates, where faster-flowing ice from a tributary or side arm transfers into the slower-moving main glacier body, looping surface debris into teardrop or oval patterns.

#Refreezing #SurfaceRunoff ❄️👉💧 Current measurements and models often overestimate how much meltwater from Greenland’s ice sheet enters the ocean because they miss key retention processes. Much meltwater refreezes in porous ice or ponds, cutting actual runoff by 9–15% compared to older estimates.
