Geomagnetic Impulses and the Electrical Conductivity of the Lower Mantle [PDF]

, 1991
This thesis is an investigation of the changes in the magnetic field as measured at the surface of the Earth on the time-scale of months to decades. In particular the phenomena of geomagnetic "impulses" or "jerks" are investigated.

Ecohydrologically important subsurface structures in peatlands revealed by ground-penetrating radar and complex conductivity surveys. [PDF]

, 2008
The surface pattern of vegetation influences the composition and humification of peat laid down during the development of a bog, producing a subsurface hydrological structure that is expected to affect both the rate and pattern of water flow.
