PMEL is coordinating the NOAA effort on the Russian-American Long-Term Census of the Arctic (RUSALCA) cruise. The 40 day cruise left on September 1 and is being conducted to observe physical and biological environmental changes in the Northern Bering and Chukchi Seas.

For more information please visit the RUSALCA web site on the Arctic theme page.

The NOAA supported Arctic Report Card for 2009 was released on October 22nd. PMEL scientist Dr. James Overland and University of Washington scientist Dr. Muyin Wang contributed to the report that states that warming of the Arctic continues to be widespread, and in some cases, dramatic.

To read more about the atmosphere, sea ice, biology and other topics in the Arctic please visit the 2009 Arctic Report Card web site.

Drs. James Overland and Richard Feely will help represent the United States and NOAA at the upcoming United Nations Climate Change Conference (COP15) in Copenhagen, Denmark that begins on December 7.  Dr. Overland will discuss global warming in the Arctic and Dr. Feely will talk about ocean acidification and its impacts on the marine ecosystem. 

Please visit PMEL’s Arctic and ocean acidification web pages for more information on these topics and follow the COP15 online

On March 16, 2010 PMEL launched a new web site to help those interested in the Arctic learn more about the longer-reaching impacts of the loss of Arctic summer sea ice with a new website, https://www.pmel.noaa.gov/arctic-zone/future/. Changes in the Arctic are not only affecting sea ice but models show that they can impact weather in the mid-latitudes as well, where a large part of the population lives.

Released October 21: The 2010 Arctic Report Card highlights record temperatures across Canadian Arctic and Greenland, a reduced summer sea ice cover; record snow cover decreases and links to some Northern Hemisphere weather to support the conclusion that a return to previous Arctic conditions is unlikely. 

PMEL scientist Dr. James Overland, co-editor of the Arctic Report Card, describes how the Arctic climate is impacting mid-latitude weather, as seen in Winter 2009-2010, in the Atmosphere section of the report.

Please visit the 2010 Arctic Report Card web site for the full report.

In recent press, notably the New York Times, Arctic atmosphere circulation has been a hot topic.  PMEL's Dr. Jim Overland explains that the Polar Vortex, a ring of winds circling the North Pole and providing a fence keeping cold air north, has broken down for the second year in a row. This breakdown allows cold air to spill south, affecting the U.S. East Coast and other regions.

NOAA has updated the Arctic Future website to reflect recent observations and add results in the Arctic Council 2011 Snow, Water, Ice and Permafrost in the Arctic assessment.  Other topics include: satellites show the Arctic losing summer sea ice for the past 30 years, an increased linkage between the Arctic and mid-latitudes, and glacier melt contributing to sea level rise.

Released in the beginning of December the 2011 Arctic Report Card concludes that there are now a sufficient number of years of observational data to indicate a shift in the Arctic Ocean system since 2006.  Persistent warming and record-setting changes are occurring throughout the Arctic environment with resultant impacts on Arctic ecosystems.

PMEL’s Drs. James Overland and Sue Moore contributed to the report that was prepared by an international team of 121 scientists from 14 different countries.

A study led by PMEL's Dr James Overland, published in the October 10 issue of Geophysical Research Letters, shows how changes in summer Arctic wind patterns contribute not only to unprecedented loss of Arctic sea ice, but could also bring about shifts in North American and European weather.

Dr. Overland and others shows a change in the summer Arctic wind pattern over the past six years when compared to patterns for the previous 20 years.  For more information see the NOAA press release.

JISAO scientist, Dr. Kevin Wood, along with NOAA and the U.S. National Archives are teaming with Old Weather and thousands of citizen volunteers to transcribe climate data from historical ship logbooks into modern digital formats that can be used to extend modern global climate data sets to earlier times in order to better understand the climate of today.

Visit the new Arctic Rediscovery website which includes a gallery of photos revealing fascinating details of life on historical ships in the Bering Sea/Arctic, related student projects, and other resources.
