  1. Impacts of Open Arctic to Specific Regions By: Jill F. Hasling, CCM Chief Consulting Meteorologist – MatthewsDaniel Weather September 2014

  2. Open Arctic records • Since 2007, Summer Open Arctic records are set at 3 year intervals. • Multi-year ice lasts through the summer. • Ice is concentrated on the Canadian side of the Arctic Ocean and has disappeared from the Eurasian Arctic waters and coasts.

  3. Comparison of median ice extent

  4. DIFFERENCE OF ICE CONCENTRATION IN March 2012 and august 2012

  5. Arctic ice growth from 2012 to 2013

  39. OPEN ARCTIC MEANS MORE STORMS ALONG THE ARCTIC CIRCLE

  40. Open Arctic • From 2000 to 2010, about 1,900 cyclones churned across the top of the world each year, leaving warm water and air in their wakes—and melting sea ice in the Arctic Ocean. • When you narrow the search down to cyclones that occurred directly over the Arctic Ocean, you find more than 200 to 300 storms per year

  41. 2000 - 2006 1950 - 1972 Greenland Greenland Canada Russia Canada Russia Data from Arctic buoys reporting surface air temperatures and sea level pressure were used to create sparse storm tracks from 1950 to 1972. Buoys also captured the data used to create the more abundant storm tracks from 2000 to 2006. Credit: NASA.

  42. More storms mean… • More storms mean more snow. This means a colder atmosphere as sun’s radiation is reflected back into the space.

  43. Tracks of polar lows in the summer

  44. Observed waves • Reviewing the Observed Waves in the Chukchi Sea and the Kara Sea, you see that when the ice retreats the wind fetch increases. If you assume that the near zero wave heights indicate ice, you can see on the following charts that the drilling season could be longer depending on your drilling location.

  45. 1979-1988 1990-1999 2000-2012 • Significant Wave heights in the Chukchi sea (July - Nov.)

  46. 1979-1988 1990-1999 2000-2012 • Significant Wave heights in the Kara sea (July - Nov.)
