Study Observes What Happens to Ocean and Sea Ice When Cyclone Hits


Study Observes What Happens to Ocean and Sea Ice When Cyclone Hits
Written by AZoCleantechApr 30 2021
A huge storm on par with a Category 2 hurricane was hit the Arctic Ocean in August 2016. The cyclone resulted in the third-lowest sea ice extent that has been recorded so far.

However, the closeness of the Korean icebreaker Araon is what made the Great Arctic Cyclone of 2016 especially attractive to researchers. For the very first time, researchers were able to observe precisely what happens to the ocean and sea ice during a cyclone. ....

Glaciers in West Antarctica are Moving Faster from Land into Ocean


Glaciers in West Antarctica are Moving Faster from Land into Ocean

A new study reports that glaciers in West Antarctica are moving into the ocean from land faster than ever, leading to increasing global sea levels.

Researchers used a 25-year record of satellite observations to demonstrate, for the first time, wide-ranging increases in ice speed throughout the Getz sector, where some portion of ice accelerated into the ocean by almost 50%.
Led by the University of Leeds, the study describes that in the Getz region, 14 glaciers are thinning and flowing faster than ever into the ocean. From 1994 to 2018, 315 gigatonnes of ice had been lost, increasing the global mean sea level by 0.9 mm, which is equivalent to 126 million Olympic swimming pools of water. ....

University of Leeds | News > Environment > Glaciers accelerate in the Getz region of West Antarctica


Glaciers in West Antarctica are moving more quickly from land into the ocean, contributing to rising global sea levels.
A 25-year record of satellite observations has been used to show widespread increases in ice speed across the Getz sector for the first time, with some ice accelerating into the ocean by nearly 50%.
The new study, led by the University of Leeds, reports that 14 glaciers in the Getz region are thinning and flowing more quickly into the ocean. Between 1994 and 2018, 315 gigatonnes of ice has been lost, adding 0.9 mm to global mean sea level – equivalent to 126 million Olympic swimming pools of water.   ....
