English. Biographical Note

W. Maurice Ewing (1906-1974) was a marine geologist, oceanographer and geophysicist. He worked at Lehigh University, the Woods Hole Oceanographic Institution, the Lamont-Doherty Geophysical Observatory of Columbia University and the University of Texas and helped to found the Marine Geophysics Institute. He is well known for his theory of ice ages, his exploration of mid-ocean ridges and his work in geophysical instrumentation.

 Scope and Contents

Correspondence, speeches, teaching material, papers, photographic material, printed material, film, charts and maps concern the career of Maurice Ewing at Lehigh University, the Woods Hole Oceanographic Institution, the Lamont-Doherty Geophysical Observatory and the University of Texas. Materials document Ewing's research in marine geophysics, particularly submarine topography, crustal thickness, turbidity currents, and sediment mapping, using seismology, gravity measurement, photography, coring and drilling, and other methods. Also included is material from Ewing's student days at Rice University.
