Abstract
Broad-scale changes in sea ice have been documented across the Arctic; however, less is known about sea ice decline at smaller scales, focused at high priority areas such as marine protected areas (MPAs) or places identified as important by Indigenous Peoples. Here we develop a small-scale application of assessing sea ice change using weekly sea ice charts, and apply that to assess sea ice change in Anguniaqvia niqiqyuam MPA (ANMPA) from 1980-2019. Over that 40-year period, sea ice coverage in ANMPA decreased and open water increased by approximately a month (31.6 days at 50% ice; 33.8 days at 20% ice remaining during break up and 80% ice formed during freeze up). Break up has gone from occurring in mid to late July to occurring in late June or early July. Freeze up has changed from occurring mid-October to occurring early November. As sea ice decline may have dramatic impacts for the ecosystem and consequences for the people that rely on this important area, we highlight the need to better understand the impacts of sea ice decline in small-scale priority places and also contribute to the development of community-scale approaches to increase the accessibility of assessing change.

期刊介绍:
Arctic Science is an interdisciplinary journal that publishes original peer-reviewed research from all areas of natural science and applied science & engineering related to northern Polar Regions. The focus on basic and applied science includes the traditional knowledge and observations of the indigenous peoples of the region as well as cutting-edge developments in biological, chemical, physical and engineering science in all northern environments. Reports on interdisciplinary research are encouraged. Special issues and sections dealing with important issues in northern polar science are also considered.
