Examining Intra- and Inter-annual Dynamics of Lakes of the Mackenzie River Delta, Northwest Territories, using Sentinel-1 SAR Time Series
Under the pressures of amplified Arctic warming, developing detailed spatiotemporal understandings of Arctic surface water systems is an urgent task. This thesis establishes a method for monitoring inundation in lakes and wetlands in the Mackenzie River Delta, using Sentinel-1 SAR. The importance of...
