Denitrification as the dominant nitrogen loss process in the Arabian Sea
Ward, B.B.; Devol, A.H.; Rich, J.J.; Chang, B.X.; Bulow, S.E.; Naik, H.; Pratihary, A.K.; Jayakumar, A. (Nature Publishing Group, 2009)Primary production in over half of the world’s oceans is limited by fixed nitrogen availability. The main loss term from the fixed nitrogen inventory is the production of dinitrogen gas (N sub(2)) by heterotrophic ... -
Denitrification exceeds anammox as a nitrogen loss pathway in the Arabian Sea oxygen minimum zone
Bulow, S.E.; Rich, J.J.; Naik, H.; Pratihary, A.K.; Ward, B.B. (Elsevier, 2010)The oxygen minimum zones (OMZs) of the world oceans are sites of enhanced anaerobic nitrogen transformations, such that the largest OMZ, the Arabian Sea, is responsible for 30-50% of the oceanic water column fixed N loss. ... -
Organic carbon, and not copper, controls denitrification in oxygen minimum zones of the ocean
Ward, B.B.; Tuit, C.B.; Jayakumar, A.; Rich, J.J.; Moffett, J.; Naqvi, S.W.A. (Elsevier, 2008)Incubation experiments under trace metal clean conditions and ambient oxygen concentrations were used to investigate the response of microbial assemblages in oxygen minimum zones (OMZs) to additions of organic carbon and ...
