Timing and completeness of freeze-up on northern rivers impacts safe winter travel and may indicate responses to climate change. Open-water zones (OWZs) within ice-covered rivers are hazardous partly because their unpredictability and are suggested to be increasing in extent and persistence due to groundwater upwelling, higher winter discharge, and permafrost degradation. To better understand the distribution, variability, and mechanisms of winter OWZs, we selected nine study reaches totaling 400 kilometers (km) of the Yukon and Kuskokwim rivers and their tributaries for remote sensing analysis and field studies in western Alaska, USA. We identified 51 OWZs from late November optical imagery along these reaches ranging from 60 meters (m) to 9 km in length, inventoried their persistence over six years, and at a subset measured ice thickness, under-ice water depth and velocity, water-column and river-bed physico-chemistry.
