NATIONAL OCEANOGRAPHIC PROGRAM—1965 217 
620. BIOLOGICAL OCEANOGRAPHY PEQUEGNAT 
Critical study of important contributions defining major bio- 
logical divisions, provinces, and life zones of the oceans; 
effects of climate, chemical, and physical barriers, and phylo- 
geny on zoogeography; factors relating to population cycles; 
productivity problems; ecological interrelationships of major 
groups of plants and animals in the sea. 
621. BIOLOGICAL OCEANOGRAPHY OF PEQUEGNAT 
THE GULF OF MEXICO 
Detailed examination of selected aspects of biological oceanog- 
raphy which are of major importance to the Gulf of Mexico. 
630. GEOLOGICAL OCEANOGRAPHY KORNICKER 
Topography and characteristic features of the ocean bottom; 
marine shorelines and processes operating in the coastal zone; 
nature of marine sediments; marine transportation and deposi- 
tion of sedimentary materials; erosion of beaches. 
631. GEOLOGICAL OCEANOGRAPHY OF KORNICKER 
THE GULF OF MEXICO 
Topography, stratigraphy, paleontology, and environments of 
the Gulf; littoral region and adjacent plains; forces acting 
on shorelines and bottoms; depositional surfaces, equilibria, 
equilibrium structures; tectonics; pleistocene history of 
region. Field trips. 
640. CHEMICAL OCEANOGRAPHY HOOD 
The chemical composition and properties of sea water; the 
definition and calculation of salinity; the pH, excess base, 
and carbon dioxide system in the sea; nutrients, their cycles, 
and their distribution; oxygen and other dissolved gases; chem- 
istry of sedimentation; composition of organisms and organic 
constituents of sea water; marine corrosion; extraction of 
raw materials from the sea. 
641. CHEMICAL OCEANOGRAPHY HOOD 
Detailed study of selected topics in chemical oceanography 
which pertain to the Gulf of Mexico; industrial utilization of 
sea water and chemical products obtained from marine plants 
and animals; water freshening; industrial corrosion problems; 
chemical aspects of photosynthesis and fertility of the sea; 
chemistry of estuarine waters.
