Deeper Mysteries

"The first detailed views of vast stretches of the seafloor in U.S. coastal waters have revealed features so immense and unexpected that they defy the imaginations of the scientists who discovered them." A special sonar device named Gloria is being employed to produce high resolution maps of the seafloor. Apparently previous sonar sounding methods missed startling underwater volcanos, canyons, and immense delta-like deposits. About 170 miles off San Francisco, near a huge volcanic structure, Gloria discovered an underwater canyon comparable in size to the Grand Canyon. No one really knows how it was formed. This great chasm is associated with a delta-like deposit twice the area of Massachusetts. Normally, one expects alluvial fans at the ends of canyons, but in this instance the submarine canyon actually cuts down into the fan. Where such a huge mass of material came from is a mystery rivaling that of the canyon's origin.

Science Frontiers Sourcebook Project Reviewed in:


  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler). Lightning, Auroras, Nocturnal Lights, and Related Luminous Phenomena" reviwed by Joseph M. Moran, Univ. of Wisconsin in Science Books and Films, Sep/Oct 1983

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W. R., Journal of the Royal Astronomical Society of Canada, Vol. 81, no. 1 (1987), p. 24., 02/1987
