Abstract

The study area is located around Shannon Ø and Pendulum Øer between 75°N and 74°N in the transition zone between the fast ice and pack ice. The AA. name the polynya the ‘Sirius Water Polynya’, and examines its spatial and temporal dynamics by analysis of recent satellite imagery, modelled meteorological data and historical data covering the last decade. A marked seasonal difference in the surface wind field, together with the obvious seasonal cycle in insolation, creates distinct winter and summer regimes in the seasonal evolution of the polynya. Some of the most persistent areas of open water in the polynya coincide with locations where significant concentrations of spring and summer settlements from the Thule Inuit culture (AD 1400-1850) are observed, indicating a connection between the presence of the polynya and the Thule Inuit living in the area in prehistoric times
