SOUTH GEORGIA — Researchers from the British Antarctic Survey have found an increase of blue whales around the island of South Georgia near Antarctica.
The whale population in South Georgia declined due to extensive hunting in the early 20th century, according to BBC News.
The researchers embarked on several missions to the waters of South Georgia from January 1, 2018 to January 1, 2020 and spotted roughly 55 blue whales.
Researchers used advanced acoustics to locate different whales and attached satellite tags to identify them. They also collected skin samples and flew drones over the whales to assess their body conditions.
The report suggests that the whales may be returning to South Georgia waters for feeding purposes which is, in turn, impacting the reproductive rate of the whale population.
According to British Antarctic Survey's website, South Georgia may have been an important place for many whale species in the past due to its influx of Antarctic krill and immense seasonal productivity.
