Today’s Image of the Day from NASA Earth Observatory features an “ice arch” in the Nares Strait that prevents sea ice from escaping the Arctic Ocean and drifting south.
The structure usually breaks up by June or July, and the timing of its collapse has an influence on how much ice will be lost from the Nares Strait in any given year.
In 2019, the ice arch crumbled in mid-April and allowed sea ice to flow freely by May.
The ice arch is more stable this year, and remained intact on May 22 when this image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite.
