Stable C and N isotopes and percent C as well as N composition of plankton from the North Atlantic

Elemental C and N percent composition and natural abundance of stable C and N isotopes of plankton species and/or size-fractions collected in several cruises on the N Atlantic Ocean from Greenland to Norway and around Iceland. Determinations included key copepod and krill species. Lipid extraction was performed in some samples to determine carbón isotope depletion factors.
