  1. AdaClim Greenland (June-August)2005

  2. AdaClim 2005 • Quantify differences in local oceanographic conditions between the two study sites (eastern and western Greenland Sea). • (2) Determine the trophic status of the two Little Auk(Alle alle) populations. • (3) Compare the predatory efficiencies of the two populations. • (4) Examine the breeding strategies and adult survival of Little Auks. • These trials will be a first step towards a better understanding of how Arctic marine predators reactto climate change.
