On succesful completion of this module, students should be able to demonstrate knowledge of :-
- methods by which the sea floor is investigated
- the types of sediment which occur from a delta to the deep ocean floor
- the processes which control ocean sedimentation
- the operation of the ODP
- the relationships between tectonics and the ocean basins
- the types of minerals and other resources of the ocean
The scope and range of Oceanography. The variety of methods and techniques used in the investigation of the marine geological environment. The processes and products of marine sedimentation from continental shelves to the deep oceans including biological and bacterial influences.
