Using lake sediment cores collected in southern Greenland, researchers have reconstructed the region’s climate record for the past 3,000 years. L'Anse aux Meadows was the first Viking settlement believed to have been found in North America in the 1960s. In 2016, scientists claimed to have uncovered another Viking settlement in Newfoundland that was built between 800AD and 1300AD. This would be the third Viking settlement claimed to have been found in North America, although it could be hard to ever prove. The chironomids – a mix of different lake fly species – hold a record of oxygen isotopes in their preserved exoskeletons.
