area of cooperation under the agreement. This action recognized the 
fact that chemistry is fundamentally related to other areas of the 
agreement, namely, marine geology and geophysics, ocean currents 
of planetary scale and other questions of ocean dynamics, and large- 
scale ocean-atmosphere interaction. 
Cooperative geochemistry activites are now to be carried out 
primarily as part of the deep sea drilling project (DSDP) through 
geochemical examination of deep ocean sediment cores. Studies in 
marine chemistry are to be carried out as integral parts of the physical 
oceanographic studies in ocean dynamics and through studies of gas 
exchange in the ocean-atmosphere program area. 
GEOLOGICAL GEOPHYSICAL, AND GEOCHEMICAL INVESTIGATIONS OF THE FLOOR 
OF THE WORLD OCEAN, INCLUDING DEEP SEA DRILLING FOR SCIENTIFIC 
PURPOSES 
Most of the cooperative projects in geology, geophysics, and 
geochemistry are related in that they contribute information and ideas 
to be tested by the International Program of Ocean Drilling (IPOD). 
This has been the most active area of cooperation under the agree- 
ment with not only a broad scope of scientific projects, but also 
a wide geographic range of activities. 
Within the agreement a separate memorandum of understanding 
between the National Science Foundation and the Academy of 
Sciences, U.S.S.R., for Soviet participation in deep sea drilling project 
was signed in February 1974 at the time of the First Joint Committee 
Meeting. The DSDP, involving the U.S. vessel Glomar Challenger, 
is aimed at obtaining geological samples of the sedimentary and crustal 
layers of the oceanic crust in order to develop geological models 
and determine the history of the sea floor. As a participant in the 
DSDP the Soviet Union, through the memorandum of understanding, 
contributes annually U.S. dollars amounting to a total of $1 million. 
In turn, space is available for Soviet scientists on each cruise of 
the Glomar Challenger and during some cruises they serve as cochief 
scientists. 
Soviet scientists have participated in research cruises during 1974 
and 1975 aboard Glomar Challenger in areas ranging from Antarctic 
waters to the Norwegian Sea. Three Soviet scientists have served 
as cochief scientists and a research cruise was conducted in the Black 
Sea in May-June 1975 with a Soviet cochief scientist for that leg. 
In addition, the U.S.S.R. has contributed shore laboratory analyses 
of samples that have been included in the publication of the Initial 
Reports of the Deep Sea Drilling Project. More than 10 Soviet 
research institutions have been involved in the analysis of deep sea 
drilling samples. Both Soviet and U.S. research vessels engaged in 
other geological and geophysical projects under the agreement also 
have conducted site surveys for Glomar Challenger operations. 
A program of marine geophysical research directed toward IPOD 
site surveys was conducted in the western part of a Trans-Atlantic 
Geophysical Traverse between Cape Hatteras and Cape Blanc, North 
Africa, in April-May 1975 by the U.S. vessel Vema. In Febru- 
ary—March 1975, a joint study of the structure and processes of metal 
logenesis of the Mid-Atlantic Ridge Crest in the area of the Trans- 
Atlantic Geophysical Traverse was carried out aboard the Soviet vessel 
Akademik Kurchatov. In addition to providing site surveys for IPOD,
