ABSTRACT

Which nutrients limit primary production in coastal marine environments? Using large (13 000 1) mesocosms with sediments we explored nutrient limitation in Narragansett Bay, Rhode Island, USA, over a 9 wk period. Separate and combined additions of phosphorus and nitrogen were made to the enclosures. Phytoplankton biomass, daytime whole system oxygen production and nighttime whole system respiration showed an approximately 5-fold increase in nitrogen and nitrogen + phosphorus treatments, whereas phosphorus treatments had somewhat lower phytoplankton biomass and metabolism than controls. In these whole system experiments nitrogen was the nutrient most limiting to primary production.
