Sunday, January 19th 2020, 12:40 pm - The ice disk garnered much affair publicly in 2019, so the City of Westbrook was quick to bring its recent reformation to light
A floating ice disk that first appeared in the Presumpscot River in Westbrook, Maine, in 2019 has resurfaced -- much to the delight of local residents.
When a similar disk was spotted this month, the city quickly took advantage and brought it to light publicly, posting a video of the phenomenon on social media.
At what point can we call this an ice disk? This aerial was taken this afternoon. The ice "formation" has grown in the past 24 hours. This is in the same location as last year's spectacular ice disk. #icedisk2020 #icedisk #westbrookmaine 📸:Tina Radel @NatGeo @nytimes @BBCNewsCity Of Westbrook ME on Twitter
A similar spinning ice disk was captured in Quebec in February 2019.
According to Mark Battle, an associate physics professor at Bowdoin College in Brunswick, Maine, the ice disk occurs when a circular current underneath the ice creates a whirlpool effect.
