Detection of subsurface permafrost features with ground‐penetrating radar, Barrow, Alaska

Abstract: A ground‐penetrating radar (GPR) survey was conducted in May 1999 on the 1 km2 Circumpolar Active Layer Monitoring (CALM) grid 5 km east of Barrow, Alaska. Spatially continuous measurements were collected along established transects while the active layer remained frozen. The primary objectives were to determine the ‘long‐term’ position of the permafrost table, to recognize ice wedges and ice lenses, and to locate the organic–mineral soil interface. GPR signal and core collection were performed in tandem to ve… Show more

“…The GPR data worked well for identifying the permafrost table with high confidence, especially in the top 2 m where sediment cores could be easily obtained for validation and signal velocity estimates. This suitability of GPR for identifying permafrost interfaces in the top 1-2 m has been shown in several studies (e.g., Doolittle et al, 1992;Hinkel et al, 2001;Moorman et al, 2003). The ERT data, using the setup in this study, do not yield data in the uppermost part of the ground and also have higher uncertainty where resistivity contrasts are high (Fig.…”

“…Ground penetrating radar (GPR) has been used extensively in permafrost studies for identifying the boundaries of permafrost (e.g., Arcone et al, 1998;Doolittle et al, 1992;Hinkel et al, 2001;Moorman et al, 2003), characterizing ground ice structures (De Pascale et al, 2008;Hinkel et al, 2001;Moorman et al, 2003), and estimating seasonal thaw depth and moisture content of the active layer (Gacitua et al, 2012;Westermann et al, 2010). Electrical resistivity tomography (ERT) has also been widely applied in permafrost studies (Hauck et al, 2003;Ishikawa et al, 2001;Kneisel et al, 2000), the majority of which focus on mountain permafrost.…”

“…This presents a useful distinction to enable the study of permafrost and to characterize areas of permanently frozen ground [Scott et al, 1990;Dallimore and Davis, 1992;Moorman et al, 2003]. Thus, geophysical techniques are widely accepted in permafrost and periglacial process studies such as those of the active layer [Doolittle et al, 1990;Hinkel et al, 2001], rock glaciers [e.g., Vonder Mühll and Schmid, 1993;F. Lehmann et al, unpublished manuscript, 1999], palsas [Doolittle et al, 1992], and pingos [Kovacs and Morey, 1985;Ross et al, 2005].…”

“…These activities complement shallow seismic (Chirp) measurements collected as a presurvey of the sediment fill in the preceding summer season (see Figure 1). GPR sounding is an established technique for permafrost investigations (Annan and Davis, 1976;Arcone et al, 1998;Judge et al, 1991;Robinson et al, 1997;Hinkel et al, 2001), active layer surveys (Doolittle et al, 1990) and lake-sediment profiling (Mellet, 1995). Mellet (1995) and Moorman and Michel (1997) have shown the potential of the GPR method for surveying sediments through a lake-ice cover.…”
