Satellites Observe More Bleaching of Great Barrier Reef

Studying European Space Agency (ESA) Sentinel-2 images captured over the reef between January and April 2017, scientists working under ESA’s Sen2Coral project noticed areas that were likely to be coral appearing to turn bright white, then darken as time went on. The event was confirmed by two successive images captured in February, indicating the approximate

Scientists, Satellites Monitor ‘Golden Tides’

The Atlantic Ocean’s Sargasso Sea is named for its floating masses of Sargassum algae that are essential to local marine life. However, these drifting “islands” may be shifting to new areas on both sides of the tropical Atlantic Ocean. If they reach land, the massive algal blooms can affect local fisheries and tourism. The authors

Oroville Lake Water Elevation Seen from Space

Toulouse – Due to recent and heavy rainfall, the water level of Lake Oroville has drastically increased, reaching a dangerous peak which led to the evacuation of over 100,000 people as a precaution, in case there was a dam failure. The Airbus SPOT 6 and SPOT 7 satellites constantly acquire imagery at 1.5m resolution on

Space Laser Reveals Cycle of Polar Phytoplankton

A new study using a NASA satellite instrument orbiting Earth found that small, environmental changes in polar food webs significantly influence the boom-and-bust cycles of phytoplankton. These findings, recently published in Nature Geoscience, will supply important data for ecosystem management, commercial fisheries and understanding of the interactions among Earth’s climate and key ocean ecosystems. “It’s

Seized Underwater Drone Raises Tension between U.S., China

The Chinese seizure of a U.S. underwater drone in waters near The Philippines is raising international concern as well as highlighting the growing strategic and tactical significance of unmanned underwater vehicles (UUVs). According to a statement from Pentagon spokesman Peter Cook, “Using appropriate government-to-government channels, the Department of Defense has called upon China to immediately

Warmer Ocean Waters Seen to Spur Drought in Africa

Monitoring drought vital to success of humanitarian relief “Really?” and “Strange, but true” might be popular reactions to the idea that periodic El Niño events in the Pacific Ocean could have a long distance influence on drought conditions in Africa, almost half-a-world away. Unlikely as it may seem, these connections are widely accepted by climate

RapidScat Mission to Monitor Ocean Winds Ends

On Sept. 21, 2014, NASA scientists and engineers launched RapidScat toward the orbiting International Space Station, 250 miles above Earth’s surface, with a few objectives in mind: improve weather forecasting on Earth, provide cross-calibration for all international satellites that monitor ocean winds, and improve estimates of how ocean winds change throughout the day. Following the
