Journal ArticleDOI
Production of N 2 through Anaerobic Ammonium Oxidation Coupled to Nitrate Reduction in Marine Sediments
Bo Thamdrup,Tage Dalsgaard +1 more
TL;DR: It is found that a process novel to the marine nitrogen cycle, anaerobic oxidation of ammonium coupled to nitrate reduction, contributes substantially to N2 production in marine sediments.
Journal ArticleDOI
N2 production by the anammox reaction in the anoxic water column of Golfo Dulce, Costa Rica.
TL;DR: The anammox reaction is shown to be a globally significant sink for oceanic nitrogen in the anoxic waters of Golfo Dulce, a 200-m-deep coastal bay in Costa Rica, where it accounts for 19–35% of the total N2 formation in the water column.
Journal ArticleDOI
Anaerobic ammonium oxidation (anammox) in the marine environment
TL;DR: The bacteria conducting anammox are highly specialized and appear to belong to the Planctomycetales, and it may be responsible for up to 50% of the global removal of fixed nitrogen from the oceans.
Journal ArticleDOI
A Cryptic Sulfur Cycle in Oxygen-Minimum–Zone Waters off the Chilean Coast
Donald E. Canfield,Frank J. Stewart,Bo Thamdrup,Loreto De Brabandere,Tage Dalsgaard,Edward F. DeLong,Niels Peter Revsbech,Osvaldo Ulloa +7 more
TL;DR: It is shown that both sulfate reduction and sulfide oxidation contribute to energy flux and elemental cycling in oxygen-free waters off the coast of northern Chile, suggesting that it may influence biogeochemical cycling in the global ocean.
Journal ArticleDOI
Microenvironment and photosynthesis of zooxanthellae in scleractinian corals studied with microsensors for O2, pH and light
TL;DR: In this article, the authors showed that coral respiration in light was calculated as the difference between the measured gross and net photosynthesis, and was found to be >6 times higher at a saturating irradiance of 350 pEm m 2 s 1 than the dark respiration measured under identical hydrodynamic conditions (flow rate of 5 to 6 cm ssl).
