The second-largest reservoir in the United States now stands at its lowest level since it was filled in the mid-1960s. The view from above is sobering. Lake Powell, a key component of the western U.S. water system, is currently filled to just 26 percent of capacity, its lowest point since 1967. On August 22, 2022,

New research on Antarctica, including the first map of iceberg calving, doubles the previous estimates of loss from ice shelves and details how the continent is changing. The greatest uncertainty in forecasting global sea-level rise is how Antarctica’s ice loss will accelerate as the climate warms. Two studies published Aug. 10, 2022, and led by

Water is life, but for all its importance, humanity has a surprisingly limited view of Earth’s freshwater bodies. Researchers have reliable water-level measurements for only a few thousand lakes around the world, and little to no data on some of the planet’s important river systems. The upcoming Surface Water and Ocean Topography (SWOT) satellite will

With the 2022 hurricane season upon us, the importance of using science-backed solutions for hurricane preparedness is brought to the foreground. Since Colombia’s Caribbean islands were devastated by hurricanes Eta and Iota within a two-week period back in November 2020, government-funded researchers have been using wave and current data measured by Nortek’s ocean sensors to

A very small instrument has a big job ahead of it: measuring all Earth-directed energy coming from the Sun and helping scientists understand how that energy influences our planet’s severe weather, climate change and other global forces. About the size of a shoebox or gaming console, the Compact Total Irradiance Monitor (CTIM) is the smallest

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
