Dr. Kristina Keating’s research focuses on using near surface geophysics to investigate the top 100 m’s of Earth’s surface. In particular, she is interested in using near-surface geophysics for hydrogeologic, biogeochemical, and cryosphere investigations. Dr. Keating uses standard geophysical methods including seismic refraction and electrical resistivity, but much of her research is focused on a novel geophysical method, nuclear magnetic resonance (NMR). Past and on-going studies in her research group includes field investigations to understand the depth and distribution of permafrost in Svalbard, laboratory studies to improve geophysical estimations of hydraulic conductivity, and computer modeling to improve the interpretation and analysis of geophysical data.

Speaker: Dr. Lili Xia, Rutgers University
Sulfate geoengineering has been discussed frequently as anthropogenic global warming is continuing, and currently we lack an adequate mitigation strategy to keep global average temperature from rising to 2°C above the pre-industrial level. With sulfate geoengineering, climate factors important for agriculture will change, including temperature, precipitation, total solar radiation, diffuse radiation, ultraviolet radiation, and surface ozone. Currently, there are only five regional agriculture impacts studies using process-based crop models under different geoengineering scenarios. Those results are varied and difficult to compare with each other. More studies are needed in this area.
