The vertical nitrogen flux caused by zooplankton diel vertical migration
Three species of vertically migrating copepods (Pleuromamma pisekii, P. gracilis and P. abdominalis) were collected at dawn and at dusk from the upper 200 m in the North Atlantic (36.5°N, 19.2°W) between 11 and 18 July 1996. For all 3 species, the nitrogen content of individuals caught at dawn was s...
