Abstract Kwasniewski, S., Gluchowska, M., Walkusz, W., Karnovsky, N. J., Jakubas, D., Wojczulanis-Jakubas, K., Harding, A. M. A., Goszczko, I., Cisek, Beszczynska-Möller, Walczowski, Weslawski, J. and Stempniewicz, L. 2012. Interannual changes in zooplankton on the West Spitsbergen Shelf relation to hydrography their consequences for diet of planktivorous seabirds. – ICES Journal Marine Science, 69: 890–901. The purpose work was determine how atmospheric oceanic processes (the North Atlantic Oscillation (NAO) Arctic Ocean (AOO)) influence (WSS), impacts chick meals zooplanktivorous little auks Alle alle. There were distinct oceanographic domains shelf resulting from presence Current Sørkapp Current, which contain different proportions Calanus finmarchicus C. glacialis. abundance warm- cold-water species varied as a result an interplay between atmosphere ocean. In domain, study focused, NAO impacted oceanography, zooplankton, consequently auk meals, with time-lags 4–7 years. chicks more energy-rich when glacialis stage 5 community easily available. To date, WSS have not posed threat ability feed lipid-rich copepods.
