Unmanned Aircraft Test Flights Completed at Oliktok Point

In October 2012, a small flight team including staff from New Mexico State University (NMSU) and Sandia began the first in a series of test flights for the DOE Atmospheric Radiation Measurement (ARM) Facility to evaluate various unmanned aerial systems (UASs) in the frigid Arctic conditions at Oliktok Point, Alaska. For eight days, the team [...]

The Rush to Exploit an Increasingly Ice-Free Arctic

It’s that time of year again, when we check in to see where the annual Arctic sea ice minimum will end up. We haven’t quite bottomed out at the end of the melt season, yet, but already 2012 has set new records for smallest Arctic sea ice extent and volume, smashing through the numbers from 2007. Records are often [...]

Alaskan North Slope Climate: Hard Data from a Hard Place

Mark Ivey—manager for Sandia of the Department of Energy’s Atmospheric Radiation Measurement (ARM) climate research facility at Barrow—is waiting for the automated release of a weather balloon … [which] measures the Arctic atmosphere’s temperature, humidity, and wind speeds at a rapid succession of altitudes as it rises. The data gathering is part of an ongoing [...]

Miniature Sandia Sensors’ Self-Sealing Valves May Advance Climate Studies

Air-quality monitoring can be a tricky business. Gasses may be blown into the sampling site from another area, they may leak out of an air sample before it can be analyzed, or the sampling container itself may introduce compounds, emitted through off-gassing. If samples are being gathered in remote areas, it can also be difficult getting bulky [...]

Sandia Releases First Findings from Its Continuous Reliability Enhancement for Wind (CREW) Database

More than 1,200 MW of wind power capacity was installed in the United States in the third quarter of 2011 alone, bringing new installations through the first three quarters of the year to 3,360 MW, according to the American Wind Energy Association (AWEA). The U.S. wind industry now totals 43,461 MW of cumulative wind capacity through the end of September [...]
