Ocean Terrain and the Engineering Challenges for Offshore Wind Farms
Deep coastal seabeds, glacial erratics, and other geophysical hurdles stand in the way of offshore wind farm proliferation. Researchers, engineers, and organizations are adapting and inventing ways to harness the breeze.
Mammoths Lost Their Steppe Habitat to Climate Change
Ancient plant and animal DNA buried in Arctic sediments preserve a 50,000-year history of Arctic ecosystems, suggesting that climate change contributed to mammoth extinction.
New Theory Connects Tree Uprooting and Sediment Movement
Tree throw from extreme wind events plays an important role in the movement of sediment and erosion on forested hillslopes. A new theory offers a novel way to measure its impact.
Roman-Era Millstone and Mixer Makers Knew Their Rocks
The geochemistry of basalt millstones and mixers from the city of Volubilis suggests a local origin—and that rocks were picked for specific purposes, from crushing olives to mixing dough.
Cosmic Dust May Be Key Source of Phosphorus for Life on Earth
When tiny particles enter Earth’s atmosphere, a newly described series of chemical reactions may lead to production of phosphorus-containing molecules that are essential for biological processes.
Sobreviviendo en la periferia de una ciudad de terremotos
La Ciudad de México es una de las áreas urbanas más propensas a desastres del mundo. Después de un terremoto, las comunidades marginadas que viven en la periferia de la ciudad están expuestas a más peligros que el simple derrumbe de edificios.
Identifying an Eruption “Tipping Point” in Hot Spot Volcanoes
By analyzing lava samples, researchers show how chemical processes that occur during magma’s ascent to the surface may contribute to a volcano’s eruptible state.
Stratospheric Balloons Listen In on Ground Activity
Solar-powered hot-air balloons, floating 2.5 times as high as Mount Everest, detected a buried explosion more clearly than ground-based sensors did.
The “Internet of Things” Boosts Agricultural Livelihoods in India
New technology is bringing better connectivity to remote areas, helping farmers improve crop yields and allowing fisherfolk to venture more safely out into the sea.
Windjamming on the Warming Gulf of Maine
Living in Geologic Time: A sailing venture reveals economic upheaval along Maine’s enduring coast.
