  abstract = {{O}xygen minimum zones are expanding globally, and at present account for around 20-40% of oceanic nitrogen loss. {H}eterotrophic denitrification and anammox-anaerobic ammonium oxidation with nitrite-are responsible for most nitrogen loss in these low-oxygen waters. {A}nammox is particularly significant in the eastern tropical {S}outh {P}acific, one of the largest oxygen minimum zones globally. {H}owever, the factors that regulate anammox-driven nitrogen loss have remained unclear. {H}ere, we present a comprehensive nitrogen budget for the eastern tropical {S}outh {P}acific oxygen minimum zone, using measurements of nutrient concentrations, experimentally determined rates of nitrogen transformation and a numerical model of export production. {A}nammox was the dominant mode of nitrogen loss at the time of sampling. {R}ates of anammox, and related nitrogen transformations, were greatest in the productive shelf waters, and tailed off with distance from the coast. {W}ithin the shelf region, anammox activity peaked in both upper and bottom waters. {O}verall, rates of nitrogen transformation, including anammox, were strongly correlated with the export of organic matter. {W}e suggest that the sinking of organic matter, and thus the release of ammonium into the water column, together with benthic ammonium release, fuel nitrogen loss from oxygen minimum zones.},
