occassionally forms part of the overall strategy for geophysical survey. This adds a depth component which can further our understanding of sites where the plan approaches of magnetic gradiometry or electrical resistivity are applied.
Earthwork Survey, Tulsk, Co Roscommon
An important addition to the extensive geophysical investigation of the earthwork at Tulsk was the surveying of a number of electrical resistivity tomography traverses across critical parts of the earthwork. This resulting profiles give a clear indication of the physical compostion of the mound, and the concentrations and depths at which potential masonary evidence may be located.
Combined with the electrical resistance and magnetic gradiometry plans this information helps form the strategy for the Tulsk Excavation.
