ALBUQUERQUE, N.M. -- As the Arctic ice sheet melts and the permafrost thaws, researchers from Sandia National Laboratories continue to carefully monitor conditions there.
They have been working on the North Slope of Alaska for more than 20 years, managing two facilities as part of the Atmospheric Radiation Measurement program sponsored by the Department of Energy's Office of Science Biological and Environmental Research Program. Researchers collect measurements of atmospheric conditions using drones and unmanned balloons; the data help improve weather forecasts and sharpen climate models to capture the observed changes.
Another focus of Sandia's work in the Arctic aligns with the labs' focus on national security issues. Melting ice sheets in the Arctic reveal new natural gas resources and an unexplored ocean that could be a future military theater. Thawing permafrost crumbles road beds and threatens the physical stability of coastal infrastructure. Basic science to connect the fundamentals of these environmental changes to their social impacts -- from refining models of coastal erosion to forecasting conditions on the seafloor -- provides environmental intelligence key to Arctic security.
Finally, Sandia is establishing partnerships to ensure Arctic research continues. Last year, the labs signed cooperative research agreements with University of Alaska campuses in Fairbanks and Anchorage. Sandia researchers are involved with proposing a permanent research center in the High Arctic.
