NASA Investigates Mysterious Tracks in Greenland's Tunulliarfik Fjord.

Landsat 9 satellite imagery detected mysterious tracks scoring the icy surface of a remote fjord in Greenland, prompting an investigation by scientists with NASA’s Cryospheric Science Laboratory. While some of the lines seen in the imagery look like natural ice deformation features, others were perfectly geometrical and likely caused by vehicles moving across the surface of the ice. The tracks appeared to originate from the towns of Qassiarsuk and Narsarsuaq, suggesting that residents were out on the ice, possibly hunting or traveling.

NASA Investigates Mysterious Tracks in Greenland's Tunulliarfik Fjord.

NASA scientists have discovered long, straight lines on southern Greenland's Tunulliarfik Fjord, likely created by people using vehicles such as snowmobiles for travel or hunting. The fjord's waters were capped with a layer of sea ice when the images were captured by Landsat 9's Operational Land Imager-2 (OLI-2) on March 13, 2023. The track that runs the length of the fjord is at least 20 kilometers (12 miles) long.

Mysterious Tracks Found in Greenland's Tunulliarfik Fjord

NASA's Landsat 9 satellite captured images of Tunulliarfik Fjord in Greenland, revealing several long, straight lines connecting the towns of Narsarsuaq and Qassiarsuk, and running the length of the fjord. Many of the tracks were likely produced by vehicles, such as snowmobiles, according to scientists at NASA's Goddard Space Flight Center. The track that runs the length of the fjord is at least 20 kilometers long. The fjord's waters are ice-free much of the year, except for floating icebergs that have broken off from the glacier to the north.
