Oc-212(A). TIDES AND TIDAL CURRENTS 
Theories of the astronomical tides; the tide-producing 
forces; tidal oscillations in ocean basins; geographical 
variation of the tides; analysis and prediction of tides; 
tidal datum planes. Meteorological tides. Seiches. 
Tidal currents. 
Oc-213(B). SHALLOW-WATER OCEANOGRAPHY 
Types and characteristics of continental shelves, coasts 
and beaches; wave processes in shallow water; littoral 
currents and storm-tides. 
Oc=-214(B). MARINE ENVIRONMENTS 
The oceanography of partially enclosed water bodies; of 
estuaries, fjords, straits, river mouths, and harbors; 
and of enclosed seas. 
Oc-230(A). SPECIAL TOPICS IN OCEANOGRAPHY 
The mechanics of simple water waves; ocean-wave spectra, 
statistical properties of ocean waves, wave forces, and 
wave pressures; the movement of ships in irregular seas; 
tides, tidal currents, and the forces associated with 
them; sea-water transparency and underwater visibility. 
Oc-240(B). DESCRIPTIVE OCEANOGRAPHY

dimensional circulation in all oceans; distribution of 
temperature, salinity and oxygen; temperature-salinity rela- 
tionship. 
Oc-243(A). DYNAMIC OCEANOGRAPHY 
Turbulence and diffusion in the ocean; boundary layer flow; 
stability; dynamical models for the general circulation of 
the ocean and for special regions. 
Oc-310(B). GEOLOGICAL OCEANOGRAPHY 
Physiography of the sea floor, especially the continental 
shelf and slope, coral reefs, submarine canyons, and sea- 
mounts; marine processes that have shaped the ocean basins 
and coasts; character and distribution of sediment types 
and rates of deposition; origin of the ocean basins. 
Oc-330(A). MARINE GEOLOGY AND GEOPHYSICS
