Tunulliarfik Fjord in southern Greenland 

Today’s Image of the Day from NASA Earth Observatory features Tunulliarfik Fjord, which is located along the southern perimeter of Greenland.

“On March 13, 2023, the Operational Land Imager-2 (OLI-2) on Landsat 9 acquired these natural-color images of Tunulliarfik Fjord. The images have been pan-sharpened to bring out more detail,” says NASA.

“At the time, the fjord’s waters were capped with a layer of sea ice. Atop the ice there are several long, straight lines connecting the towns of Narsarsuaq and Qassiarsuk, and running the length of the fjord. Though cracks and ridges can form naturally in the ice, there are indications that people were likely involved with producing some of the tracks pictured here.”

The images were reviewed by Nathan Kurtz and several other scientists in the Cryospheric Sciences Laboratory at NASA’s Goddard Space Flight Center. The experts determined that many of the tracks were produced by vehicles like snowmobiles.

“It seems likely that residents from the town or nearby were out on the ice, possibly hunting or traveling,“ said Kurtz.
