My research interests include high-resolution monitoring and modeling techniques to better understand groundwater flow in spatially and temporally complex geologic systems. Methods include geochemical sampling of groundwater after recharge events, fracture flow modeling, and the use of thermal imagery from drones. My study sites have included areas in Minnesota, Missouri, Pennsylvania, Florida, and now western Montana. |

I've recently submitted a paper to the Journal of Hydrology on some of my major findings on rare earth element (REE) patterns in two adjacent karst springs after storms in central Pennsylvania. This was the bulk of my research during last summer (2017) although it began back in 2016 with baseflow sampling with a wide range of other nearby karst springs (see my earlier post, A New Chapter: jamesberglund.weebly.com/research-blog/a-new-chapter).
Rare earth elements have been getting more use lately as natural tracers in hydrologic systems as they can act as fingerprints for the different materials with which recharging and flowing water has interacted with. By collecting and analyzing spring water samples at various points throughout a storm hydrograph our aim was to better pinpoint the various sources with which the recharging water has interacted with and shed a little more light on the black box of karst aquifers. Time to wait for the revision process to get into full swing. Until then, time to work on my other paper on conduit flow modeling in FEFLOW!
