Exploring the challenges of interpreting near-surface towed TEM data on saline permafrost

This paper analyzes a continuous near-surface transient electromagnetic (TEM) survey on permafrost, around Ilulissat in western Greenland, an area characterized by continuous saline permafrost. The TEM data is severely affected by induced polarization (IP) effects, causing a large range of decay sha...
