Summit Station, Day 22, 6/25/19

Mike got right to work on making sense of the Raman and fluorescence data that had been collected leading up to his arrival. The point clouds that were collected indicate that we may have some activity going on at various depths of the borehole. The goal now is to return to those areas of interest and take 100-micron resolution mappings of these “hotspots”. On another note, a pleasantly surprising discovery has been the instrument’s ability to detect features in firn (less packed down, still has grains) ice. We had originally thought that the little grains would scatter light too much and negatively affect our analysis. But it worked great, so we are happy!
