This summer, researchers managed to collect stunning drone images of both ringed seals and walruses. In one fjord, the St. Jonsfjorden, twelve ringed seals were found spread out throughout the fjord, resting on the fast ice. However, approaching and identifying these individuals is very challenging. Since ringed seals are hunted by polar bears, any mammal—either walking on four or two legs—will be avoided at all costs.
