In this paper, a general outline of geotechnical engineering is explained briefly as one of the typical interdisciplinary subjects. Then, the focus is placed to a limited part of this broad engineering field, i.e. marine geotechnical engineering, which is related to seabed and seafloor. Education systems in the universities and prospective of recent research papers are examined to characterize this subject. Finally, some research works that the author has been involved in are introduced as typical examples of research projects in the relevant study.
