| Abstract: | More than 300 locations covering all the major ocean basins of the world, except the Arctic, have now been explored by deep-sea drilling. Results from deep-sea drilling permit the accurate calibration of seismic reflection profiles but at the same time emphasize the need for caution in interpreting the stratigraphic significance of such records. Basement ages determined from core samples are in close agreement with ages predicted by the concept of sea floor spreading, demonstrating both the validity of that concept and the validity of the paleomagnetic time scale. There also appears to be a demonstrable relationship between the age of the sea floor and its present depth. at many locations permits the documentation of changes in ocean currents, surface and bottom water temperatures, climate, and water depth. |
