Active Layer Measurements in Tanana Flats, Fairbanks, Alaska, USA
Entry ID: GGD240

[ Get Data ]

Abstract: This data set consists of active layer thickness from forested uplands (islands and benches) bordering the interconnected wetlands of Tanana Flats, near Fairbanks, Alaska. CRREL permafrost cores were taken to depths of about 1.5 m to characterize ice content, ice type, and organics in the permafrost. Data were collected in 1989, and from 1992 to the present. The project aimed at describing and understanding the origin of the permafrost wetlands and their extent in relation to vegetation, permafrost, and hydrology.
