Water column denitrification rate

Value 150 Tg N/year
Organism Biosphere
Reference L. A. Codispoti, An oceanic fixed nitrogen sink exceeding 400 TgNa-1 vs the concept of homeostasis in the fixed-nitrogen inventory, Biogeosciences, 4, 233–253, 2007 Table - link
Comments Tg=Teragram=10^12 grams. “pro forma” in title of table, means that most of the budget terms are highly uncertain. For total oceanic denitrification rate of 400 and Benthic denitrification rate of 300 Tg N/year See BNID 104774, 104777, respectively.
