Zooplankton Composition and Abundance in the Laptev Sea and adjacent Nansen Basin, summer, 1993 (Polarstern ARK-IX/4)
Zooplankton composition and distribution were investigated on the Laptev Sea shelf, over the continental slope and in the adjacent deep Nansen Basin during the joint German-Russian expedition "Arctic 93'' with RV Polarstern and Ivan Kireyev in August/September 1993. Zooplankton was co...
