Unlike those areas, Coral Harbour remains beneath in terms of average high in the midst of winter. Throughout December 2010 and early January 2011, Nunavut, northern Quebec and western Greenland set many high temperature records. In Coral Harbour, a high of in mid-December broke the old record of set in 1963. The daily minimum temperature on 6 January 2011, was about warmer than normal. The unusual warmth was due largely to an unseasonal area of high pressure over Greenland, and very negative values of the Arctic oscillation and North Atlantic oscillation. Mostly in the 21st century, the conditions have combined to produce an Arctic dipole anomaly that brings warm air to the Arctic regions and cold air to the continents. Geological resources The limestone around Coral Harbour (and nearby regions of Bad Cache Rapids) predominantly have a "Low Purity" value for industrial use.
