The National Science Foundation (NSF), lead federal agency for planning and conducting U.S. Arctic research—and formulating and implementing U.S. Arctic research policy—has announced establishment of the Arctic Observing Network (AON). NSF describes AON “. . . as a system of atmospheric, land- and ocean-based environmental monitoring capabilities—from ocean buoys to satellites—that will significantly advance our observations of Arctic environmental conditions.
Information, data and operating experience from the AON is seen as enabling an interagency initiative—known as the Study of Environmental Arctic Change (SEARCH)—to provide significant insight into environmental and climate changes in the Arctic. The Arctic Research Consortium of the United States (ARCUS) characterizes SEARCH as “. . .an effort to understand the nature, extent, and future development of the system-scale change[s] presently seen in the Arctic. These changes are occurring across terrestrial, oceanic, atmospheric and human systems, including:
increased air temperatures over most of the Arctic;
changing ocean circulation and rising coastal sea level;
reduced sea ice cover; and
thawing permafrost.”
