Mapping of the oceans under consideration of the plate tectonics

Dr. M. Márton

Summary

 

Ocean and sea-bottom topography have intensivelyˇbeen carried out for the recent years and this work is going on increasingly. Further to opening up oil and gas localities on the shelfs, surveying of deep sea, of the ocean territories becomes also important on account of prospective oreˇsites and for military reasons, as well.

 

We have still not become fully acquainted with this territory and thus every indirect, non bathymetricˇmethod that helps us become more acquainted withˇthe suboceanic surface is of great importance.

 

After reviewing the problems, the traditional and up-to-date methods of ocean mapping, the author speaks about cartographic extrapolation i. e. about using the results of plate tectonics in compiling small scale maps. In this connection the most important theses of plate tectonics are also reviewed.
