In recent years, residents of Spain, France and the UK have looked up to see an eerie sight: deep orange sunrises and skies thick with a yellowish haze. These hazy skies often deposit “blood rain,” […]

Both winds and tides inject energy into the ocean. Much of that energy is then transported up to thousands of miles by internal waves: large-scale underwater waves that can travel between ocean basins. Quantifying the […]

Offshore wind farms are an important pillar of the European Union’s strategy for renewable energy—by 2050, the EU aims to increase capacity in the North Sea more than tenfold. A new study by the Helmholtz-Zentrum […]

Sea ice is sticking to Alaska’s northern coast for less time each year, according to 27 years of data analyzed by University of Alaska Fairbanks scientists. Such landfast ice, which stays attached to the shoreline […]

A new Stanford University study has helped solve a mystery about dramatic swings in sea ice extent around Antarctica.This post was originally published on this site

A new study finds that commercial satellite imagery data often outperforms public data sets when identifying surface water, but that public data sets may be better at detecting water hidden by forest cover. Satellite imagery […]

Understanding what triggers large volcanic eruptions is crucial for hazard assessment, but the exact mechanism driving these eruptions is still poorly understood. The prevailing theory is that volatile exsolution—gas coming out of magma—is a main […]

Severe Tropical Cyclone Narelle continues to amaze us with its long journey across northern Australia. This cyclone began life near the Solomon Islands on March 16, when moist air rose rapidly and created a low-pressure […]

Although volcanic eruptions are spectacular natural events that occur around the world every day, most volcanoes spend the majority of their time not erupting. To accurately forecast volcanic activity, it’s important to characterize the magma […]

The magma reservoir of the largest volcanic eruption of the Holocene is refilling. This Kobe University insight on the Kikai caldera in Japan allows us to understand giant caldera volcanoes like Yellowstone or Toba more […]
