tritium, etc. The expedition was financed by the German Research 
Association (DFG). Present plans are for the METEOR to make seve- 
ral east-west cross sections in the Atlantic during the north-south 
Atlantic GEOSECS expeditions. Professor Munnich has participated 
in both the Pacific (1969) and Atlantic (1970) GEOSECS trial sec- 
tions. Contact is maintained through Dr. Broecker.

Professor Horibe has just finished two sections of the Pacific 
(30°N, 65°S and east-west, Japan to Seattle) with the Institute's 
new ship Hakuho Maru with a program similar to GEOSECS. The north- 
south section - the "Southern Cross Expedition - report has been 
published. The program involves measurements of the C0, system 
parameters, use of a mass spectrometer aboard ship for dissolved 
gas and many other parameters. Professor Horibe and another Jap- 
anese investigator participated in the 1971 GEOSECS Pacific shake- 
down expedition on R/V MELVILLE (ANTIPODE). Japanese expeditions 
are being planned by this group for the Pacific during the GEOSECS 
sections there. Contact is maintained through Dr. Craig.
