Recent developments in geophysical data analysis suggest that in addition to a multi-method approach, “data fusion” techniques can offer meaningful insights into archaeological features, as well as allow for researchers to establish patterns between multivariate data sets that might otherwise go unnoticed. Extensive and intensive geophysical prospection has been employed at the site of Portus i...

In this paper, a 2 X 2 factorial design was used to assess the main and interaction effects of GSS and facilitation on knowledge restructuring under experimental conditions. To measure knowledge restructuring, the concept mapping technique and similarity coefficient were used to evaluate the level of restructuring of individual structural knowledge (complexity and integration) and the commonali...

The main paleopositions that have been proposed for Madagascar are examined after a recent geological and geophysical survey in the Mozambique Channel. Results from that survey show a north-south ridgelike feature and favor the theory that Madagascar fitted against Somalia rather than against Mozambique to the west.

In this thesis, the results from a geophysical mapping and coring campaign of Lagoa das Furnas are presented. Specific focus is placed on the origin of a subaqueous volcanic cone mapped in the southern part of the lake. Lagoa das Furnas is a crater lake within the Furnas volcanic centre which is located on the island of São Miguel in the Azores archipelago. The Furnas volcanic centre has a long...

Understanding how geophysical and hydrologic properties are related is a key problem in hydrogeophysical data fusion. Traditionally this link has been made by rock physics investigations that define how pore-scale variations in properties like mineralogy, fluid content, and grain geometry affect the geophysical response of a rock or sediment. As the scale of investigation increases from the lab...
