Category 3: Abstract

The isotopes of nitrate, which show different dynamics than nitrate concentration during physical transport and nitrate assimilation, provide a complementary constraint in the effort to understand nutrient transport and biogeochemical fluxes in the Southern Ocean. For instance…
