On 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 (Jones et al., In Review). This dataset includes the geospatial files created for the study that do...

This dataset includes the geospatial files created for the study that documents the expansion and drainage of a small lake on the Schaeffer's Native allotment near Qikiqtaġruk (Kotzebue), Alaska.
