Glucose in the Atlantic was measured along a transoceanic section by two independent techniques. The concentrations varied from a high of 10 −8 m to values below 10 −8 m . The highest concentrations occurred within 480 km of Bermuda although significant concentrations were also associated with the area of upwelling off Senegal. Densities of phytoplankton exhibited a positive correlation with the glucose concentration. Experiments on glucose uptake by the natural microbial population showed the common occurrence of glucose users in the sea but also pointed out the need for enzymatic adaptation whenever glucose was absent or present below a critical concentration.
