3. Sedimentation in estuaries - texture and foraminif eral 

 assemblages related to estuary circulation and hydrography. 



4. Astoria Fan and Astoria Submarine Canyon - structure sedi- 

 ments composition and processes. 



At the Scripps Institution of Oceanography, J. R. Curray, in asso- 

 ciation with D. Moore of the U. S. Navy Electronics Laboratory (NEL) is 

 working on the following projects: continuing the study of structure, 

 sediments, quaternary history and origin of the continental terrace - 

 as a world-wide feature. Extensive work is being done at present on the 

 coasts of California and Mexico. 



F, P. Shepard is continuing investigation of submarine canyons and 

 associated phenomena - Bahamas, Cape San Lucas, La Jolla, Scripps and 

 Baja California. 



D. L. Inman is engaged in several projects - mechanics of sedimenta- 

 tion by waves, currents and winds (fluid mechanics), continuing a study 

 of processes in Scripps Canyon , and shoreward migration of beach sands 



as traveling dunes. 



E, W, Fager is studying shallow-water benthic communities and their 

 role in stabilizing sand bottoms. 



At Texas AgzM University, a group, working with R. D, Gaul, operate 

 instrumented towers off Panama City, Florida, for continuous observation 

 of currents, waves, and other phenomena. Associated projects involve 

 waves and their modification, sediment transport, and coastal currents. 



R. 0. Reid is investigating the influence of bottom topography on 

 coastal currents near the Mississippi Delta and Apalachicola Bay. 



John W. Antoine, using reflection and refraction techniques, is making 

 an intensive study of the geophysical structure of the Gulf and Caribbean. 

 Early concentration was on the east Gulf Shelf and the study is now pro- 

 gressing westward. 



W. R. Bryant is conducting an investigation of the stratigraphy, 

 mineralogy and mass properties of sediments from the Mississippi River. 



At the Lament Geological Observatory, M. Ewing and associates are 

 engaged in an extensive world-wide study of structure and sediments - not 

 easy to localize on any region of the North American coast. 



At the University of Miami, E. D. Traganza is working on a detailed, 

 continuing study of the chemistry of environment relating to carbonate 

 deposition on the Bahama Banks.
