Ice sheet/glacier - ocean interaction and its consequence on the society in northwestern Greenland



Study site: Qaanaaq region
Qaanaaq is a village in northwestern Greenland populated by approximately 600 residents. In this region, snow and ice related research activities have been carried out by Japanese researchers since around 2000. The village is located on the coast of a peninsula, which is covered by Qaanaaq Ice Cap except for its coastline. Bordering the village is the entrance to Inglefield Bredning, an approximately 100 km long and 20 km wide glacial fjord system. Sea ice covers the fjord during winter until it breaks up in spring, generally in July. Sea ice seasonality is crucial for the local community because it enables people to use dog sledges and snowmobiles. The timing of sea ice break-up is of great interest to the residents because the first supply ship of the year can dock as soon as the sea ice allows it. Because several marine-terminating glaciers feed the fjord, icebergs are abundant near the village. They are utilized as a freshwater resource in wintertime. Several smaller settlements are found in the Qaanaaq region. Siorapaluk is situated ~50 km northwest from Qaanaaq on the coast of a glacial fjord connected to Baffin Bay. A large colony of little auks is situated near the settlement, where residents catch seabirds with a traditional hand net. Qeqertat is a settlement situated ~60 km east of Qaanaaq in the inner part of Inglefield Bredning. The area close to Qeqertat is a key site for narwhal hunting during the summer and halibut fishing during the winter. These settlements are populated by ~20-30 people each.
