The Particulate Organic Carbon-to-Nitrogen Ratio Varies With Ocean Currents

Ocean currents could adjust ocean carbon and nitrogen composition which are an important part of the global cycle. We procured concentrations particulate in different depths, classified them according to (upper 300 m), analyzed POC-to-PON ratio (particulate organic carbon-to-nitrogen ratio) variations. found that regions with have a higher than those without northern hemisphere, except 50°–60°N (median is 8.38). Warm ranges from 5.96 8.44) cold (6.19–8.89), for East Greenland Current (reach Labrador 8.89). Meanwhile, we also effects currents’ flowing distributions vary current types (e.g., cause formation distance shore). Generally speaking, eolian near-ocean change fiercer compensation near-coast currents. buffering effect variation between surface deep water, prevents severe ratio. The high-value anomaly caused by confluence warm was analyzed. It can be deduced high high-latitude region mainly terrigenous matter (especially carbon) low nitrogen.
