PurposeResearch
ObjectivesTo study the trophic interactions occurring between phytoplankton (particularly pico- and nanophytoplankton), bacteria and protozoa in a shelf-sea pelagic ecosystem. The emphasis of the experimental work was on qualifying the flow of energy through the microbial components of the food web, the so called "microbial loop". The individual specialists participating in the cruise determined specific aspects of the physiology of natural populations of picoplankton and protozoa; in addition attempts were made to bring ecologically significant picoplankton and protozoa into axenic culture. The NERC Analytical Flow Cytometer was successfully deployed on this cruise for the first time at sea.
