Thick-billed murre colony size in relation to spring sea ice conditions, West Greenland
Box 8. Sea ice conditions, primary production, and colony size of Greenland seabirds
Figure 28. Thick-billed murre colony size in relation to spring sea ice conditions, West Greenland Based on analyses of data from areas around 46 murre colonies, grouped into regions. Colony sizes are historical maximum estimates of numbers of birds (representing carrying capacity) rather than current population sizes. This approach avoids the confounding factor of overharvest in some areas in recent decades. Sea ice conditions are based on satellite measurements, 1979 to 2004.
