摘要

Recognition and sampling of traces in unconsolidated sands present a major challenge for ichnologists. This can be partially remedied through the application of high-resolution geophysical techniques, such as ground-penetrating radar (GPR or georadar), which uses electromagnetic impulse for continuous imaging of shallow subsurface. It addition to geological applications, GPR imaging has been used in several studies focused on animal traces as related to conservation of endangered fossorial species (Kinlaw et al., 2007; Martin et al., 2011), slope and levee stability (Nichol et al., 2003; Di Prinzio et al., 2010), and mapping of fossil tracks (Matthews et al., 2006; Aucoin and Hasbargen, 2010) and tracking surfaces (Webb, 2007). Few efforts have been dedicated specifically to characterizing burrow and track characteristics (Stott, 1996; Sensors & Software Inc., 2010 [compilation on geophysical projects related to animal burrows]; Buynevich and Hasiotis, 2011; Buynevich et al., 2011; Martin et al., 2011) and most of the above studies are published in journals not routinely accessed by ichnologists.
