Hot-spotting: a new way emerges to find the earth's hidden heat sources

Article Abstract:

A new technique for locating geological 'hot spots,' or concentrations of heat in the earth's mantle, has been discovered. Paul Wessel and Loren W. Kroenke claim that the new method, called hot-spotting, offers a more precise way of determining the position of these hot spots under the ocean.

A blue note: seismologists find a mysteriously pure tone in the ocean

Article Abstract:

Seismologists Jacques Talandier and Emile Okal discovered the existence of sound waves whose notes are purer than that of a musical note in French Polynesia. The sound waves were determined to be T-waves or sound waves with a frequency ranging between 3 to 12 cycles per period.

It's getting easier to find a date

Article Abstract:

Geochronologists are using data on astronomical oscillations to improve radiometric dating techniques. The research on orbital oscillations in geological history may lead to a process for calibrating argon-argon dating methods.
