Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: April 1976 Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: April 1976
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory; therefore it should be regarded as preliminary.

Rise of a variable-viscosity fluid in a steadily spreading wedge-shaped conduit with accreting walls Rise of a variable-viscosity fluid in a steadily spreading wedge-shaped conduit with accreting walls
Relatively rigid plates making up the outer 50 to 100 km of the Earth are steadily separating from one another along narrow globe-circling zones of submarine volcanism, the oceanic spreading centers. Continuity requires that the viscous underlying material rise beneath spreading centers and accrete onto the steadily diverging plates. It is likely that during the rise the viscosity...
