Sentences with phrase «electrical resistivity tomography»

For example, Dafflon et al. [2017] demonstrated in a polygonal tundra how soil electrical resistivity tomography and vegetation activity cameras can be merged with in situ measurements in a way to corroborate the role of active layer thickness and polygon geometry on spatial control on productivity, and demonstrate how changes in solute concentration and unfrozen water content in winter contributes to acceleration of permafrost thaw.

Folarin Kolawole of Oklahoma State University and colleagues have made the first comprehensive observations of those features with a «CAT scan» - style technology called high resolution electrical resistivity tomography (ERT).
