Geophysics

UNL Geophysics Group

The Geophysics Research Group exists at the Department of Earth and Atmospheric Sciences since August 2016. Unlike many other geophysical research programs that focus on the application or development of a single geophysical method, our group, led by Dr. Irina Filina, utilizes the integrative approach in geophysical data analysis. We are looking for the answer (i.e. the geological model of the subsurface) that fits ALL available geophysical data and remains geologically valid. The data we use include seismic (reflections, refractions, earthquakes), gravity and magnetics both from public domain sources, as well as acquired by our own instruments.

Research

Our group conducts research in several directions (more details here and here):

• Tectonic history of the passive continetal margins (Gulf of Mexico and the Northern Atlantic)
• Crustal structures of the Cascadia subduction zone

• Intraplate Seamounts in the central Atlantic

• Geophysical studies in Nebraska

The students of the UNL Geophysics team present their results at professional meetings (see here), and at the local venues as well. The UNL Geophysics team receives the Best Student Awards at the annual meetings of the Nebraska Academy of Sciences (NAS) every year starting 2017. A list of past NAS meetings' talks is here and UNL Research Fair posters and talks are listed here.
