Contrasting associations of sea‐ice meltwater and meteoric water with nitrogen uptake patterns in the summer Cosmonaut Sea, Antarctica

Nitrogen uptake by phytoplankton influences Southern Ocean productivity and carbon export, but how source‐resolved meltwater is associated with nitrate and ammonium use remains unclear. Here, 15 N tracer incubations and a δ 18 O‐salinity mixing model were combined to examine nitrogen uptake in the early‐summer...
