Our group has recently published two papers on a new global dataset of surface POM stoichiometry: (1) an analysis paper on the regulation of C:N:P variability and (2) a dataset paper documenting all the samples collected.
The new dataset contains 2673 paired surface POC/N/P measurements from 70°S to 73°N across all major ocean basins at high spatial resolution from Bio-GO-SHIP and Arctic cruises. It also includes 965 measurements of oxygen demand for organic carbon respiration.
Altogether, our data suggest systematic regulation of elemental stoichiometry among ocean ecosystems via temperature and nutrients. This new dataset can help validate and calibrate the next generation of global ocean biogeochemical models with flexible elemental stoichiometry. We expect that incorporating variable C:N:P:-O2 into models will help improve our estimates of critical ocean biogeochemical fluxes such as carbon export, nitrogen fixation, and organic matter remineralization.
