Mapping Permafrost and Gas Hydrate using Marine Controlled Source Electromagnetic Methods (CSEM)

The objective of this project is to develop and test a towed electromagnetic source and receiver system suitable for deployment from small coastal vessels to map near-surface electrical structure in shallow water. The system will be used to collect permafrost data in the shallow water of the U.S. Beaufort Inner Shelf at locations coincident with seismic lines collected by the U.S. Geological Survey (USGS). The electromagnetic data will be used to identify the geometry, extent, and physical properties of permafrost and any associated gas hydrate in order to provide a baseline for future studies of the effects of any climate-driven dissociation of permafrost and hydrate. Results will be used to expand the geological and geographical applications of marine electromagnetic methods, and provide a geophysical tool to complement the seismic methods currently being used.
