Deep-Sea Sensors Aid Search for Rare Whales

Using a new system of drifting buoys, scientists from NOAA’s Southwest Fisheries Science Center in La Jolla, Calif., will have a much better chance of hearing beaked whales in their deep-water habitat off the West Coast. About 20 buoys will be deployed from a NOAA ship with a listening device suspended 330 feet below the

CubeSat Set to Monitor Ionosphere

Construction of NASA’s Dellingr CubeSat is complete, and the satellite now is ready for environmental testing. Named for the god of dawn in Norse mythology, Dellingr will study the ionosphere—the outer region of Earth’s atmosphere populated by charged particles ionized by incoming solar radiation and magnetospheric particle precipitation. Slightly larger than a cereal box, Dellingr

First Space-Based LiDAR Ready for Launch

The pioneering Aladin sensor, a spaceborne LiDAR instrument with two powerful lasers, a large telescope and very sensitive receivers, is ready to join its Aeolus satellite for launch in 2017. Designed by Airbus Defence and Space, Aladin’s laser generates ultraviolet light beamed toward Earth, which bounces off air molecules and small particles such as dust,

Next-Generation CO2 Detector Nearing Operation

NASA scientists and engineers are field testing the CO2 Sounder LiDAR, an instrument powerful and accurate enough to gather around-the-clock global atmospheric carbon-dioxide (CO2) measurements from space. The instrument is a strong contender for a potential next-generation carbon-monitoring mission, the Active Sensing of CO2 Emissions over Nights, Days and Seasons (ASCENDS). The LiDAR operates by

Isolated Coral Reefs Far from Human Activity Are Not Healthier

For the world’s coral reefs, the picture keeps getting gloomier. Although it’s widely assumed that both local and global factors are contributing to their decline, new research from the University of North Carolina at Chapel Hill shows that isolated reefs far from human activities are in fact not healthier than those in more densely populated
