Its look has actually been compared to a moon, an alien production, a crop circle and a huge Lazy Susan; regardless, a vast disk of ice spinning in the Presumpscot River in Westbrook, Maine, has individuals talking.
According to report, the disk extends as much as 330 feet (100 meters) throughout and is spinning in a counterclockwise instructions. (Ducks seen taking a spin stimulated the example to a duck-go-round)
A drone video reveals the beautiful ice development in all its splendor, gradually turning in what seems a small bend in the river, with little eddies rolling by in the narrow passage not crowded out by the disk. [7 Crazy Things That Happen Only When It’s Really Cold]
” It appears like the moon has actually landed in Westbrook!” the city published on its Facebook page
Though not unusual, the wintry reward is “uncommon,” stated Ted Scambos, senior research study researcher at the National Snow and Ice Data Center at the University of Colorado-Boulder.
” I believe you can see how it is formed– that side of the river has a big eddy in the water present that traps the ice,” Scambos informed Live Science. “Due to the fact that of the rotation, and most likely periodic running into the coastline– and the reality that the ice is freezing into a strong plate, the ice that collected in the eddy was caught and infiltrated a huge disk.”
When it comes to why the big pancake of ice appears so completely circular, Scambos stated that involves the size of the ice inside.
” If it were simply loose pieces of ice, the ice would simply trace the shape of the eddy (which is most likely less circular, more oval or egg-shaped),” Scambos stated. “Nevertheless, as it gradually froze into a strong plate, and considering that pieces of ice are most likely being included from upstream, it gradually became a completely circular disk.”
A comparable, though smaller sized, paddy of ice formed in the Sheyenne River in North Dakota in November 2013, Live Science formerly reported. That turning disk was likewise driven by an eddy in the river. And, in 1993, researchers from MIT recommended eddies was accountable for likewise spinning, yet much smaller sized, ice disks, Live Science reported
” I have not personally [seen an ice disk like this], however these are seen sometimes in the best conditions, generally at a bend in a river where eddies prevail,” Walt Meier, senior research study researcher at the National Snow and Ice Data Center, informed Live Science.
Presumpscot has actually most likely hosted such a development in its past.
” I would wager that this is not the very first time in history this has actually been observed there, unless the shape of the river bank was just recently altered in a considerable method,” Scambos stated of the Westbrook ice.
With snow projection for this weekend, could the huge grow even bigger? We will see.
