A new Defense Advanced Research Project Agency (DARPA) program, Near Zero Power RF and Sensor Operations (N-ZERO), aims to passively monitor the environment, activating only when detecting specific events. The idea is to detect and recognize specific attention-worthy events and reject other readings and signal interference, staying asleep yet aware.
Scientists Probe Methane Mystery in Four Corners Region
Researchers are working in the Four Corners region of the U.S. Southwest to understand a mysterious methane concentration detected by a European methane-measuring satellite instrument that was operational between 2003 and 2009. The greenhouse gas measurements will be enhanced with a multipart scientific mission that includes ground, airborne and spaceborne measurements.
Scientists Declare Substantial Risk for Greater Sage-Grouse Habitat
Scientists from the U.S. Geological Survey analyzed nearly 30 years of Landsat Earth observation data over 3,216 square miles of southwestern Wyoming to forecast sagebrush habitat to the year 2050. The exercise was precipitated by the consideration under way for listing the sage grouse as a threatened or endangered species by the U.S. Fish and Wildlife Service.
Surface Movement Monitored in Beijing
The TerraSar-X satellite is well-suited to surface movement monitoring with its frequent revisits and radar interferometry techniques. The company has employed this service successfully for a variety of civil engineering and infrastructure projects.
Multiple Satellite Eyes to Track Algal Threat to U.S. Freshwater
RESTON, Va., April 7, 2015â€”Four federal agencies including the U.S. Geological Survey have joined forces in an effort to transform satellite data into vital information to protect the American public from freshwater contaminated by harmful algal blooms. The $3.6...
Carbon Emissions Could Dramatically Increase Risk of U.S. Megadroughts
Droughts in the U.S. Southwest and Central Plains during the second half of the 21st century could be drier and longer than any droughts seen in those regions during the past 1,000 years. In a new study published in the journal Science Advances on Feb. 12, 2015,...
Air Shepherd Uses Drones and Predictive Analytics to Combat Poaching in Africa
An alarming increase in poaching of elephants and rhinos in Africa has led to some innovative approaches to combat the growing problem. Air Shepherd, an initiative of the Lindbergh Foundation, uses unmanned aircraft systems to monitor animals in South Africa.

NEON Airborne Data Now Includes Full Waveform LiDAR
The National Ecological Observation Network (NEON) recently released new sample data from its Airborne Observation Platform. The full-waveform light detection and ranging (LiDAR) data are collected using light energy to measure object heights on the ground; assess plant density and species; and map buildings, power lines and other infrastructure.
