Stable isotope compositions of arctic copepods in the Greenland Sea in winter (scientific note)
Natural abundances of stable isotopes (δ^<13>C and δ^<15>N) were measured in copepods collected in the Greenland Sea in January 1999. Standing stocks of zooplankton dominated by copepods in the upper 200m varied among 12 stations and marked zooplankton increases at 4 stations (>10 mg-...
