Integrating local environmental observations and remote sensing to better understand the life cycle of a thermokarst lake in Arctic Alaska
ABSTRACTOn 29 June 2022, local observers reported the drainage of a 0.5 ha lake near Qikiqtaġruk (Kotzebue), Alaska, that prompted this collaborative study on the life cycle of a thermokarst lake in the Arctic. Prior to its drainage, the lake expanded from 0.13 ha in 1951 to 0.54 ha in 2021 at later...
