A deployment method for in situ oceanic primary production measurement
A launch, suspension and recovery technique for oceanic, in situ , 14C productivity measurements is described. Ship's time for deployment of 125 ml incubation bottles at several depths down to 100 m is approximately 10 minutes but another half hour is required for water sampling and laboratory...
