Quantifying river migration rates in the Yukon River Watershed from optical satellite imagery, Alaska, 2016-2022 ...
This dataset describes measurements of river migration rates (averaged over the period 2016-2022) in three locations within the Yukon River Watershed: Huslia, Alaska (AK) (65.700 N, 156.387 W), Beaver, AK (66.362 N, 147.398 W), and Alakanuk, AK (62.685 N, 164.644 W). Huslia is located on the Koyukuk...

Huslia is located on the Koyukuk River and Beaver and Alakanuk are located on the Yukon River.
