The U.S. Geological Survey (USGS) assessed that the upper Paleozoic reservoirs of the Wind River, Bighorn and Powder River basins has technically recoverable resources of 47 million barrels of oil and 876 billion cubic feet of gas. This area includes Wyoming and parts of southern Montana as well as parts of western South Dakota and Nebraska. Since exploration

In the wake of the aircraft collision over the Potomac River near Ronald Reagan Washington National Airport (DCA), NOAA’s National Ocean Service activated response teams to support response and recovery efforts. Tragically, the incident claimed all 67 lives aboard the two aircraft and created significant recovery and salvage obstacles due to the frigid waters and complex wreckage

Launched just two months ago and still in the process of being commissioned for service, the Copernicus Sentinel-1C satellite is, remarkably, already showing how its radar data can be used to map the shape of Earth’s land surface with extreme precision. These first cross-satellite “interferometry” results assure its ability to monitor subsidence, uplift, glacier flow,

Data from the Copernicus Sentinel-5P mission was used to study and estimate methane emissions at 217 potential locations, as shown on the accompanying map. The paper, published in Atmosphere, Chemistry and Physics, focused on sources that emit methane gradually over time, in contrast to ‘super-emitters,’ typically oil and gas operations, coal mines or poorly managed landfills, which release

The Surface Water and Ocean Topography (SWOT) mission instruments have allowed for the clearest satellite-produced map of the seafloor to date, according to a new study in Science. The work could help researchers better understand everything from biodiversity hotspots to plate tectonics to tsunami propagation. Ship-based sonar has a resolution of about 200-400 meters (650-1,300 feet). The Seabed 2030 project aims

ESA’s 5G/6G laboratory at its European Space Research and Technology Centre (ESTEC) in the Netherlands successfully connected to the LEO 3 satellite operated by Telesat, a leading global satellite operator. The test was made possible through a Memorandum of Understanding signed earlier this year between ESA and Telesat, which provided access to the LEO 3 demonstration satellite.

An international team of scientists using observations from NASA-German satellites found evidence that Earth’s total amount of freshwater dropped abruptly starting in May 2014 and has remained low ever since. Reporting in Surveys in Geophysics, the researchers suggested the shift could indicate Earth’s continents have entered a persistently drier phase. From 2015 through 2023, satellite measurements

As Europe grapples with unprecedented floods and Asia faces the fury of typhoons, a different crisis is unfolding in South America: record droughts. Geographers Elzė Buslavičiūtė and Dr. Laurynas Jukna from Vilnius University’s Department of Geography and Landscape Management shed light on alarming conditions in the Amazon basin, where river levels have plummeted to historic

The global ocean absorbs roughly a quarter of carbon emissions from human activities, which is extremely important in helping to slow climate change. On the flip side, however, this benefit does come at a cost: as oceans take in more carbon, their waters become more acidic, endangering the health of marine ecosystems. Enhancing our understanding

As goods of all shapes and sizes journey from factory to doorstep, chances are they’ve stopped at a warehouse along the way—likely several of them. The sprawling structures are waypoints in the logistics networks that make e-commerce possible. Yet the convenience comes with tradeoffs, as illustrated in a recent NASA-funded study. Published in the journal GeoHealth,
