  • In Situ electromagnetic heating for hydrocarbon recovery and environmental remediation

    Introduction Thermal recovery methods, as applied in heavy oil and oil sand deposits, and in environmental remediation, have the common objective of accelerating the hydrocarbon recovery process. Raising the temperature of the host formation reduces the oil and bitumen viscosity, and, in environmental remediation, increases vapour pressure. These effects assist in sweeping the substances ...

  • Electromagnetic detection of a 410-km-deep melt layer in the southwestern United States.

    A deep-seated melt or fluid layer on top of the 410-km-deep seismic discontinuity in Earth’s upper mantle, as proposed in the transition-zone ‘waterfilter’ hypothesis, may have significant bearing on mantle dynamics and chemical differentiation. The geophysical detection of such a layer has, however, proved difficult. Magnetotelluric and geomagnetic depth sounding are geophysical methods ...

  • Magnetic and ground probing radar measurements for soil pollution mapping in the industrial area of Val Basento (Basilicata Region, Southern Italy): a case study

    Abstract  The joint application of electromagnetic techniques for near-surface exploration is a useful tool for soil pollution monitoring and can also contribute towards describing the spatial distribution of pollutants. The results of a geophysical field survey that was carried out for characterizing the heavy metal and waste disposal soil pollution phenomena in the industrial area of Val ...


  • Issues concerning spectral analysis of water samples for monitoring and treatment of public water resources

    Experimental measurements conducted in the laboratory, involving hyperspectral analysis of water samples taken from public water resources, have motivated a re-evaluation of issues concerning the potential application of this type of analysis for water monitoring, treatment and evaluation prior to filtration. One issue concerns hyperspectral monitoring of contaminants with respect to types and ...

  • Archaeological survey 2

    The site of the Meadows’ Wesleyan Cemetery in the Adelaide is thought to contain more than 130 unmarked graves. This site initially had a chapel constructed on it in 1840 and the first burial in 1855.  The initial chapel was replaced by a more substantial stone building in 1856.  Burials continued in this cemetery sporadically until the 1940’s although the site became less ...

  • City Of West Palm Beach Reaches Out To Community With Proactive Approach To Manage Critical Force Main

    The City of West Palm Beach (WPB) makes a concerted effort to engage its citizens. As one of the three largest cities in South Florida, WPB is a vibrant, growing waterfront community with a population of more than 100,000. Since 1974, WPB has experienced exponential growth in its population and correspondingly, in its wastewater ...

  • Case Study - Construction Aggregate: Sand

    Geologic Mapping of Sand Unit Thickness Pyramid was contracted to perform an electrical resistivity survey across 230 acres of undeveloped land in North Carolina. The purpose of the survey was to quantify the lateral extents and approximate depth/thicknesses of sandy soils near the ground surface. The client was interested in the potential of the site to be utilized as a sand mine, and ...

  • Mapping of freshwater aquifers by GeoView case study

    Big Pine Key, Florida The Nature Conservancy is studying the physical and biological changes that will occur on small oceanic islands as a result of sea level rise. Big Pine Key, Florida is one of the primary areas of investigation because of extensive previous work on the key and because a large portion of the island is a National Wildlife Refuge. As part of the investigation, GeoView ...

  • Advanced gas detection technology supports arctic greenhouse gas research

    Enormous quantities of greenhouse gases (GHG) exist within Arctic ice and frozen soils, so with the threat of global warming, a clear understanding of the relationship between GHG in the atmosphere and in the ice/soil is vital because melting of permafrost could cause a dangerous climate tipping point. There can be few more challenging environments for monitoring gases, but PhD researcher Martin ...
