Theses and Dissertations
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 examined and shown to be similar to those of other researchers' work elsewhere.
Calculated sedimentation rates for glacial ice spherules, extrapolated for the entire earth's surface, range from 1.1 x 10⁴ to 1.1 x 10⁵ metric tons per year. Calculated sedimentation rates for sea ice spherules range from 5.0 x 10³ to 1.6 x 10⁵ metric …
