RELEASE OF DISSOLVED ORGANIC MATTER BY MARINE SEAWEEDS AND DISTRIBUTION OF THEIR TOTAL ORGANIC PRODUCTION TO INSHORE COMMUNITIES1
Under controlled experimental conditions, release rates of organic matter were estimated for five species of Barents Sea macrophytes and for thirteen species of Black Sea macrophytes. The release rates of different species from the Barents Sea were between 0.9 and 2.9 mg of organic matter per gram (...
