This course provides an overview of the geology, physiography, and sediments of the ocean basins, continental margins, shelves and coastal zone, formation and distribution of sediments, major substrate types, and gravity and magnetic fields. It introduces the main marine geophysical techniques (seismics, gravity, magnetics) and describes their methodology and derived information content. The course is designed to meet the marine geology and geophysics requirement for the Category A FIG/IHO/ICA Standards of Competence for Hydrographic Surveyors.
