This book responds to concern about marine eutrophication by presenting a number of invited contributions on productivity, regeneration of nutrients and nitrogen flow in pelagic and benthic marine environments. Improvements in methodologies are included and some integrated research studies are included.
Pelagic Nitrogen Cycling: Primary Productivity and Pelagic Nitrogen Cycling; Pelagic Primary Production in Nearshore Waters; Microfauna in Pelagic Food Chains; Benthic Nitrogen Cycling: Benthic Primary Production and Oxygen Profiles; Benthic Nitrogen Fixation; Amino Acids and Amines in Marine Particulate Material and Sediments; Distribution and Metabolism of Quaternary Amines in Marine Sediments; Benthic Mineralization and Bacterial Production; Nitrogen in Benthic Food Chains; Nitrification in Estuarine and Coastal Marine Sediments; Nitrate Reduction and Denitrification in Marine Sediments; Benthic Fauna and Biogeochemical Processes in Marine Sediements: The Role of Burrow Structures; Benthic Fauna and Biogeochemical Processes in Marine Sediments: Microbial Activities and Fluxes; Models of Nitrogen Cycling: Modelling Benthic Nitrogen Cycling in Temperate Coastal Ecosystems; Nitrogen Models at the Community Level: Plant-Animal-Microbe Interactions; Nitrogen Biogeochemistry and Modelling of Carmarthen Bay.
