Alaska permafrost characterization: Borehole Nuclear Magnetic Resonance (NMR) data collected in 2021 Geophysical measurements were collected by the U.S. Geological Survey (USGS) at five sites in Interior Alaska in September 2021 for the purposes of imaging permafrost structure and quantifying variations in subsurface moisture content in relation to thaw features. Borehole nuclear magnetic resonance (NMR) data were collected at two sites in order to determine liquid water content at depth in shallow boreholes. NMR data were collected in a 2.25 m-deep borehole at the North Star golf course adjacent to one of the ERT profiles, and in another two 1.625 m-deep boreholes adjacent to Big Trail Lake where previous NMR measurements were made in 2019 and 2020.

Values <15% are classified as ‘Low’ connectivity, values of 15-30% are classified as ‘Fair’ connectivity, and values >30% are classified as ‘Good’ connectivity.
