Abstract" literature review is conducted of geospatial technologies in community-based research on ice and mobility among Indigenous people of the circumpolar north. Numerous studies explore the use of traditional knowledge in the "rctic on sea ice, but limited evidence of community-based research in sub-"rctic communities and in freshwater ice systems is found. Geographical Information Systems GIS and remote sensing tools have been applied in a variety of ways in support of community adaptations. These include the production of living memory maps, ice classification systems, and geodatabases that reflect the relationship-building nature of collaborations between Indigenous traditional knowledge holders and scientists. Satellite imagery particularly synthetic aperture radar S"R is widely used to characterize traditional understandings of ice to help tailor geospatial tools, climate research, and early warning systems, so that they may be used more effectively to address community interests and needs. "s numerous mapping platforms have been developed in the circumpolar north, there are important considerations with respect to data management, Indigenous rights, and data sharing. We see opportunities for further research in lake and river ice, and in further developing early warning systems to address the growing problem of unpredictable ice regimes in "rctic and sub-"rctic regions.Keywords: circumpolar north, climate change, ice, traditional knowledge, geospatial technologies © 2016 The Author(s).

. IntroductionThe climate system of the circumpolar north is undergoing transformative change. "verage annual "rctic air temperatures have increased by . °C since the start of the twentieth century [ ]. "s a result, significant sea ice declines through most of the "rctic have occurred over the past years [ ], while inland, freshwater ice systems have experienced shorter seasons of ice cover due to a significantly later freeze-up and earlier breakup [ ]. The decline in sea ice leads to greater absorption of solar radiation in the "rctic Ocean in early autumn, which intensifies vertical fluxes of heat and moisture into the atmosphere, amplifying the effects of climate change in poles to approximately twice the global average [ ].Such changes have affected the mobility of Indigenous people of the north, who rely on the frozen landscape to move freely during winter months [ , ]. Sea ice, frozen lakes, and rivers act as virtual highways in the north, while seasonal winter ice roads are constructed to provide access to the north for various industries, and are crucial for bringing year-round essentials, such as food, fuel, construction, and household items into remote communities [ , ]. In recent years, travel to hunting grounds is less predictable, and ic...
