Recent climate changes have altered thermodynamic balances within high latitude watersheds, especially on the Alaskan North Slope where glacial-fed rivers flow through transitional and coastal plain tundra to the Arctic Ocean. This study examines precipitation, discharge, water and soil temperatures, turbidity, and material fluxes through the Kuparuk and Sagavanirktok watersheds on the Alaskan North Slope during the 2019 melt season. Results show that there are episodic peaks in material fluxes associated with late-summer precipitation events, integrating organic and inorganic inputs from deepened active layers.
