Arctic Issues: Expert Reports

The division produces 60-70 reports per year. These reports are unique, authoritative expert evaluations. Each report is produced by a committee of experts selected by the Academy to address a particular statement of task and is subject to a rigorous, independent peer review. The experts who volunteer their time participating on study committees are vetted to make sure that the committee has the range of expertise needed to address the task, that they have a balance of perspectives, and to identify and eliminate members with conflicts of interest. All reports undergo a rigorous, independent peer review to assure that the statement of task has been addressed, that conclusions are adequately supported, and that all important issues raised by the reviewers are addressed. Thus, while the reports represent views of the committee, they also are endorsed by the Academy.

Opportunities to Use Remote Sensing in Understanding Permafrost and Related Ecological Characteristics: Report of a Workshop (2014)

Climate change is causing the widespread thawing and degradation of permafrost, subsurface soil or rock that remains frozen for two or more consecutive years. Changes in permafrost could cause significant impacts—for example, by causing erosion that damages buildings, roads, or other infrastructure, by causing shifts in ecosystems, and by contributing large amounts of carbon to the atmosphere. Data are needed to observe and monitor permafrost... More >>

Seasonal-to-Decadal Predictions of Arctic Sea Ice: Challenges and Strategies (2012)

Watch presentations by the report's authoring committee from a webinar held on this report. View the recording > Note: requires downloading the WebEx plugin. Recent well documented reductions in the thickness and extent of Arctic sea ice cover, which can be linked to the warming climate, are affecting the global climate system and are also affecting the global economic system as marine access to the Arctic region and natural resource developmen...

Scientific Value of Arctic Sea Ice Imagery Derived Products (2009)

During the 1990s, environmental scientists and members of the intelligence community collaborated to consider potential uses of classified assets and data to advance the understanding of environmental change. This program collected classified overhead imagery at six sites around the Arctic basin. Hundreds of unclassified products derived from those images have been produced but not yet released to the public. The National Research Council ha... More >>

Earth Observations from Space: The First 50 Years of Scientific Achievements (2008)

Over the past 50 years, thousands of satellites have been sent into space on missions to collect data about the Earth. Today, the ability to forecast weather, climate, and natural hazards depends critically on these satellite-based observations. At the request of the National Aeronautics and Space Administration, the National Research Council convened a committee to examine the scientific accomplishments that have resulted from space-base...

Polar Icebreakers in a Changing World: An Assessment of U.S. Needs (2006)

The United States has enduring national and strategic interests in the polar regions, including citizens living above the Arctic circle and three year-round scientific stations in the Antarctic. Polar icebreaking ships are needed to access both regions. Over the past several decades, the U.S. government has supported a fleet of four icebreakers -- three multi-mission U.S. Coast Guard ships (the POLAR SEA, POLAR STAR, and HEALY) and the Nationa...
