IGPP graduate student Karen Weitemeyer awarded one of the
Anadarko/Society of Exploration Geophysicists Scholarships
IGPP graduate student Karen Weitemeyer has been awarded a scholarship
by the Society of Exploration Geophysicists. The scholarship,
cosponsored with the Anadarko Petroleum
Company, recognizes Karen's academic achievements.
Karen's research focuses on the application of marine controlled source
electromagnetics (CSEM) for gas hydrate detection. Electromagnetic (EM)
fields are generated by a source and the EM fields propagate through the
Earth's crust. These fields can be measured by EM receivers placed on the
sea floor, allowing one to make maps of lateral changes in resistivity
within the sea floor. Gas hydrates will be more resistive when compared
to surrounding sediments and it may be possible that CSEM will be a
useful tool in conjunction with seismic methods to map gas hydrates.
This will aid in mitigating the geohazards associated with gas hydrates.
Members of the Marine EM Laboratory are all responsible in part
for achieving the award by making it possible for Karen to use marine
electromagnetic methods in her thesis work. The laboratory welcomes new
graduate students interested in marine electromagnetism research.
About the SEG
The Society of Exploration Geophysicists is a not-for-profit
organization that promotes the science of geophysics and the education
of applied geophysicists. SEG, founded in 1930, fosters the expert and
ethical practice of geophysics in the exploration and development of
natural resources, in characterizing the near surface, and in mitigating
earth hazards. The Society, which has more than 25,000 members in 129
countries, fulfills its mission through its publications, conferences,
forums, Web sites, and educational opportunities.
