The Black Guillemots on Cooper Island have seen their nesting success reduced over the past four decades as sea ice decline has reduced the availability of their preferred prey.
Sea ice extent in the Arctic on June 15, 2015 was 9.1 (only one decimal point) million km sq., 10 percent less than the average for that date for 1979-2008. The above images show the proximity of sea ice to Cooper Island currently and for the same week in 2006.
