EVALUATING SPACE BASED REMOTE SENSING ALGORITHMS FOR ARCTIC SHORELINE DETECTION

In the face of climate change, Arctic coastal regions are increasingly an area of interest. Arctic sea ice loss is accelerating, which creates longer periods of open-water nearshore, potentially leaving coastal areas more vulnerable to erosion, with coastal retreat rates increasing by a factor of 2 or more (Nielsen [2022]). Understanding this change is important to protect vulnerable coastal communities and for tracking a rapidly changing region. However, this region is hard to study due to its remote location, harsh weather, often impassable seas, and lack of resources for research. This work investigates the use of space-borne sensors to quantify shoreline change and coastal morphology evolution in Arctic regions.
