Ramp-Up in Antarctic Ice Loss Speeds Sea-Level Rise

Ice losses from Antarctica have tripled since 2012, increasing global sea levels by 0.12 inches (3 millimeters) in that timeframe alone, according to a major new international climate assessment funded by NASA and the European Space Agency (ESA). According to the study, ice losses from Antarctica are causing sea levels to rise faster today than

Climate Change May Lead to Bigger Atmospheric Rivers

A new NASA-led study shows that climate change is likely to intensify extreme weather events known as atmospheric rivers across most of the globe by the end of this century, while slightly reducing their number. The new study projects atmospheric rivers will be significantly longer and wider than the ones we observe today, leading to

Antarctica Loses Grip

The European Space Agency (ESA) CryoSat mission revealed that, during the last seven years, Antarctica has lost an area of underwater ice the size of Greater London. This is because warm ocean water beneath the continent’s floating margins is eating away at the ice attached to the seabed. Most Antarctic glaciers flow straight into the

Oceangate and 2G Robotics to Laser Scan Titanic Shipwreck and Debris Field

OceanGate Inc., a provider of manned submersible services, and 2G Robotics, which develops underwater laser scanners, formed a strategic alliance to capture laser data of the RMS Titanic shipwreck and debris field. 2G Robotics ULS-500 PRO underwater laser scanner will be installed on OceanGate’s Cyclops 2, the first manned submersible to survey the Titanic since

Satellites Accurately Capture Ocean Salinity in Arctic

Monitoring ocean salinity is essential for understanding its impact on ocean circulation, Earth’s water cycle, marine ecology and climate change. Ocean salinity in the Arctic is of particular interest, because it changes significantly with seasonal ice cover and is expected to decrease as the Greenland ice sheet melts and releases massive amounts of freshwater. Despite

Satellites Provide Thermal View of Hurricane Nate after Landfall

NASA’s Aqua satellite and NASA-NOAA’s Suomi NPP satellite analyzed the temperatures in Hurricane Nate’s cloud tops and determined that the most powerful thunderstorms and heaviest rain areas were around the center of the tropical cyclone after it made landfall near the mouth of the Mississippi River on Oct. 7, 2017. Infrared light provides valuable temperature

Darkness Blooms off Brazil

In early September 2017, ocean scientists noticed something swirling in the waters off the coast of the Brazilian state of São Paulo. The sinuous threads of darkness amid the blue Atlantic Ocean were not caused by oil; they were the result of a phytoplankton bloom. The dark colors are probably high concentrations of dinoflagellates, according

The Remote Paradise with a Plastic Problem

In the middle of the South Pacific Ocean, far from the urban, developed world, there’s a small, lush, green island with white sand beaches. However, this uninhabited, remote corner of the tropics—Henderson Island—also has a trash problem. The beaches of Henderson Island have the highest density of plastic waste in the world, according to a

Teledyne Optech Environmental Monitoring Capabilities Highlighted at Two Conferences

Teledyne Optech’s Coastal Zone Mapping and Imaging Lidar (CZMIL) system is a critical rapid environmental assessment tool for monitoring natural and man-made disasters. From detecting sewage pipe leaks, mapping oil slicks, and measuring coastline changes after hurricanes, to counting underwater debris in the Great Pacific Garbage Patch, CZMIL excels at identifying and monitoring oceanic environmental

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
