Supplied Units:
milligrams of nitrogen per square meter per day
Description:
Total nitrogen flux of the sinking fraction operationally defined as particles <350 um. The nitrogen measured in all process blanks from the five cruises was averaged to determine the mean process blank in sediment trap tubes for the field program (0.015 +/- 0.006 mg N). This mean process blank was subtracted from the total nitrogen measured in each trap sample and the result was divided by the trap collection area (0.0113 m^2) and the deployment length to yield flux. Reported fluxes are the mean of measurements from 2 or 3 tubes.
