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 Gulf of Mexico
- Crustal structures of the Cascadia subduction zone
-
Intraplate Seamounts in the central Atlantic
- Tectonic evolution of the Northern Atlantic
- Geophysical studies in Nebraska
UNL Geophysics team in June 2021
The students of the UNL Geophysics team present their results at professional meetings (see here), and at the local venues as well. The students from the UNL Geophysics team receive the Best Student Awards at the annual meetings of the Nebraska Academy of Sciences every year starting 2017.
