Greenland’s fjords harbor a unique group of polar bears that rely on glacial ice, a NASA-funded study reports in Science. Polar bears throughout the Arctic depend on sea ice as a platform for hunting seals. As human-caused climate change warms the planet and Arctic sea ice melts away, polar bears are scrambling to find ice

Each year, strong winds carry more than a billion metric tons—the weight of 10,000 aircraft carriers—of mineral dust from Earth’s deserts and other dry regions through the atmosphere. While scientists know that the dust affects the environment and climate, they don’t have enough data to determine, in detail, what those effects are or may be

A relentless heat wave has blanketed India and Pakistan since mid-March 2022, causing dozens of deaths, fires, increased air pollution and reduced crop yields. Weather forecasts show no prospect of relief any time soon. NASA’s Ecosystem Spaceborne Thermal Radiometer Experiment on Space Station instrument (ECOSTRESS) has been measuring these temperatures from space, at the highest

By Joseph Shih, Seal-Connect Technical Product Specialist, Greene Tweed The use of distributed sensing (DS) is on the rise, especially for sensitive oil and gas and pipeline applications, structural health monitoring in concrete structures, and subsea cable infrastructure monitoring for offshore wind energy power sources. DS enables precise monitoring that can benefit operators seeking to

With a plane crisscrossing the sky and researchers working on land and sea, the Surface Biology and Geology High-Frequency Time Series campaign (SHIFT) combines the ability of airborne science instruments to gather data over widespread areas with the more concentrated observations scientists conduct in the field to study natural environments. SHIFT is jointly led by

Scientists have produced a new method that holds the promise of improving groundwater management critical to both life and agriculture in dry regions. The method sorts out how much underground water loss comes from aquifers confined in clay, which can be drained so dry that they will not recover, and how much comes from soil

On March 22, 2022, the newest U.S.-European sea-level satellite, Sentinel-6 Michael Freilich, became the official reference satellite for global sea-level measurements. This means that sea-surface height data collected by other satellites will be compared to the information produced by Sentinel-6 Michael Freilich to ensure their accuracy. Launched from Vandenberg Air Force Base in November 2020,

Air pollution is the fourth-leading risk factor for death around the world. But one type of pollutant is particularly harmful: fine particulate matter (PM2.5). These small, inhalable particles (less than 2.5 micrometers in diameter) result from direct emissions into the air as well as interactions among other pollutants. PM2.5 is the leading cause of death

An object hidden below ground has been located using quantum technology, a long-awaited milestone with profound implications for industry, human knowledge and national security. University of Birmingham researchers from the UK National Quantum Technology Hub in Sensors and Timing reported their achievement in Nature. It is the first in the world for a quantum gravity

For a nuisance-reduction program after a summer rainfall 2021, GDG was challenged to monitor a several-thousand-hectare region and treat all mosquito breeding sites within it in just five days. As a result, biological larvicide treatment was applied to nearly one thousand hectares of areas producing mosquito larvae by GDG’s drone division in 2021. “Once a
