Core Splitting!
Core Scanning!
Sam doing the hard work
MS student Sam Randall's thesis is focused on analyzing tephra from the most recent explosive eruption at Mount Baker - 6700 ypb - in alpine lake cores. As part of his project, he took cores to the CSD Facility at the University of Minnesota to perform high resolution scans of the cores!

MS student Sage jumps for joy in front of Mount Baker views.
Alpine lake core sediments see the light of day for first time in centuries!
Good thing it was summer!

MS student Saisha Brody traveled to the Woods Hole Oceanographic Institution in September 2024 to measure H2O, CO2, S, and Cl concentrations in melt inclusions from Augustine Volcano's Tephra C by Secondary Ion Mass Spectrometry.

Camp life (on the 1976 lahar deposit)
MS student Saisha Brody partook in field work at Augustine Volcano in Alaska in June 2024. In collaboration with students and faculty from Colgate University, we exposed numerous stratigraphic sections of Holocene tephra for sampling and physical volcanologic descriptions. Our goal is to better understand the eruptive history of the volcano specifically between ~300-1200 ybp.

The contact between the basaltic and basaltic andesite portions of the SC Tephra eruption
Amanda smiling with her beautiful samples!
Because the tephra of interest was exposed on the side of a steep-sided river drainage, rappelling was the only safe way to sample!
