Research Interests

  • Magnetic maps and models for use in alternative navigation 

  • Methodologies for quantification of magnetic map uncertainty

  • Communication of strategy and approach for the U.S. delineation of extended continental shelf (Law of the Sea, Article 76)

  • Innovative display of geophysical information

  • Geologic/tectonic/geodynamic interpretation of potential field data (magnetics and gravity)

  • Innovative uses of CrowdMag to incease citizen involvement in the geophysical sciences

Current Research

  • Research in support of magnetic maps and models to support alternative navigation in the absense of GPS
  • Completion and release of the US reports for definition of continental margin components with application to Article 76 of the Law of the Sea Treaty (State Department/NOAA/USGS cooperative project)
  • Improvement of EMAG2 global model of lithospheric magnetic anomalies for improvement of global full field magnetic models (CIRES Geomagnetic Team project)
  • Continued development of CrowdMag for (1) citizen scientist involvement, (2) mapping of local urban magnetic anomalies, and (3) input to global magnetic models

As part of the Research Experience for Community College Students (RECCS) program we conducted a "CrowdMag Day" data collection activity.  The pictured students and mentors each used their smartphones to collect 3-component magnetic data along a 1.5 mile traverse on the east campus of the University of Colorado.  The data were analyzed by Anjelique Morine (at left in the photo) as part of her RECCS research project.
