Underway measurement of ∆Oxygen/Argon (∆(O₂/Ar)) data collected on the Research Vessel Xuelong in the western Arctic Ocean, 2018
At present, we lack adequate knowledge of how the seasonal progression of sea ice alters the timing and magnitude of Arctic net community production (NCP) in the different physical and biogeochemical regimes (e.g., nutrient-rich shelf versus oligotrophic basin, or ice-covered versus ice-free regions...

At present, we lack adequate knowledge of how the seasonal progression of sea ice alters the timing and magnitude of Arctic net community production (NCP) in the different physical and biogeochemical regimes (e.g., nutrient-rich shelf versus oligotrophic basin, or ice-covered versus ice-free regions). Bridging the occasional snapshot views provided by field observations is important to achieving a coherent overview of seasonal NCP evolution in the Arctic Ocean, summer to fall. The goal of this project was to examine seasonal and regional variabilities in metabolic status and net community production in the western Arctic Ocean using the cruise opportunities of the Chinese National Arctic Research Expedition (CHINARE, RV Xuelong) in two years (2016 and 2018).
