Abundance of ringed seals (Phoca hispida) in the Kong Oscars Fjord, Scoresby Sund and adjacent areas in eastern Greenland
With the purpose of determining the distribution and abundance of ringed seals (Phoca hispida) hauling out on the ice, systematic strip census aerial surveys were flown in the Kong Oscars Fjord, Scoresby Sund and adjacent areas (between approximately 70°N and 72°30'N in eastern Greenland) from...
