Hi all, These are SEM images of calcareous spheres from Lake Fryxell, Antarctica. The balls are calcareous, hollow, and about 10 to 20 microns in size. They were collected from below several meters of water and ice; the water is brackish and supersaturated in CaCO3. Has anyone seen anything like this before? Any ideas as to what these are?
