Carbonate Rhombohedra and Arctic Sulfur

Here's a beautiful image that I took of one of my samples from Borup Fiord Pass. As I write up my dissertation, I'm going back through all of the data and trying to synthesize everything into one report. This image won't be used in my dissertation, but it's still pretty awesome. The image was taken using a scanning electron microscope (SEM). The scale bar is 10 microns (about one quarter of the width of one of my beard hairs!). The blocky looking structures in the middle are rhombohedra of carbonate minerals while the globular looking things around the top and right of the image are globules of elemental sulfur. This material was collected from the surface of some fresh snow and ice that had been blown out of a glacial crevasse while we were at our field site in the Arctic. I'm kind of sad that I don't have a good way to use this image in the dissertation, but glad that I can share it here!
