Abstract: Globally, mainly nitrogen or phosphorus is limiting the primary production. New nitrogen can enter estuarine ecosystems as nitrate from upwelling events, from river runoff, atmospheric deposition, or by nitrogen fixation. Primary production driven by new sources of nitrogen is generally referred to as new production and suggested to equal the size of export production. Nitrate-based new production has been reported to range between 8 % and 40 % in tropical and temperate regions. Regenerated sour... more
