I am curious about the fate of these microspheres. A skim of Wikipedia https://en.m.wikipedia.org/wiki/Glass_microsphere suggests that some can float on water. I'm unsure whether those used for this experiment would do. Any that float may ultimately become airborne (in sea spray or from wind blown shoreline deposition), leading to significant terrestrial rainout - as large material volumes are surely used. Wind blown snow is common, and lifting these spheres from the ice surface seems plausible, also.
If they don't float, they will presumably end up at the bottom of the ocean in layers comparably thick to that on the ice surface. I have no special knowledge of any of these processes, and I'd like to hear from someone who does. All my comments are curious speculating.
