title = "Nitrous oxide variability at sub-kilometre resolution in the Atlantic sector of the Southern Ocean",
abstract = "The Southern Ocean is an important region for global nitrous oxide (N2O) cycling. The contribution of different source and sink mechanisms is, however, not very well constrained due to a scarcity of seawater data from the area. Here we present high-resolution surface N2O measurements from the Atlantic sector of the Southern Ocean, taking advantage of a relatively new underway setup allowing for collection of data during transit across mesoscale features such as frontal systems and eddies. Covering a range of different environments and biogeochemical settings, N2O saturations and sea-to-air flux were highly variable: Saturations ranged from 96.5 % at the sea ice edge in the Weddell Sea to 126.1 % across the Polar Frontal Zone during transit to South Georgia. Negative sea-to-air fluxes of up to −1.3 µmol m−2 d−1 were observed in the Subantarctic Zone and highest positive fluxes of 14.5 µmol m−2 d−1 in Stromness Bay, coastal South Georgia.",
