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.

In August 2016 a massive storm on par with a Category 2 hurricane churned in the Arctic Ocean. The cyclone led to the third-lowest sea ice extent ever recorded. But what made the Great Arctic Cyclone of 2016 particularly appealing to scientists was the proximity of the Korean icebreaker Araon.
For the first time ever, scientists were able to see exactly what happens to the ocean and sea ice when a cyclone hits. University of Alaska Fairbanks researchers and their international colleagues recently published a new study showing that sea ice declined 5.7 times faster than normal during the storm. They were also able to prove that the rapid decline was driven by cyclone-triggered processes within the ocean.
Conservation groups say a large-scale oil drilling project on 1.2 million acres in northern Alaska will exacerbate climate change and harm endangered species.

(CN) A federal judge has temporarily halted construction of a massive oil and gas drilling project in northern Alaska after conservation groups asked the Ninth Circuit on Friday to block the “environmentally reckless” plan.
The Center for Biological Diversity and its allies filed their Ninth Circuit appeal on Feb. 5 after U.S. District Judge Sharon Gleason, a Barack Obama appointee, denied the groups’ motion for a preliminary injunction four days earlier.
