Upwelling velocity and eddy diffusivity from 7Be measurements used to compare vertical nutrient flux to export POC flux in the Eastern Tropical South Pacific
Description: Five 7Be profiles, measured in an area bounded by 10°S-20°S and 80°W-100°W, were used to determine upwelling velocity (wH) and vertical diffusivity (Kz). A positive correlation between wH and 14C primary production rate and a negative correlation between the inventories of 7Be and phosphate were observed. The authors of this research article interpret this as the influence of deeper, nutrient-rich, 7Be-poor water brought up by upwelling. [Source: Marine Chemistry]
