2023, Fire (6)
Few fires are known to have burned the tundra of the Arctic Slope north of the Brooks Range in Alaska, USA. A total of 90 fires between 1969 and 2022 are known. Because fire has been rare, old burns can be detected by the traces of thermokarst and distinct...
Using DC resistivity ring array surveys to resolve conductive structures around tunnels or mine-workings
Michael Albert Mitchell, Douglas W. Oldenburg
2023, Journal of Applied Geophysics (211)
In underground environments, conventional direct current (DC) resistivity surveys with a single linear array of electrodes produce fundamentally non-unique inversions. These non-uniqueness and model resolution issues stem from limitations placed on the location of transmitters (TXs) and receivers (RXs) by the geometry of existing tunnels and boreholes. Poor excitation...
