Black magnetic spherules from the glacial and sea ice of Fletcher's Ice Island (T-3)
Black magnetic spherules are particles which can be derived by ablationary processes from cosmic sources. Spherules from both the glacial ice and sea ice of Fletcher's Ice Island (T-3) were studied to determine their size distribution, sedimentation rates, and other parameters. The results were...
