A new study finds that Mars’s mantle is neon-rich, putting constraints on the planet’s formation history.
Pressure from both magma and gas can trigger eruptions. Monitoring degassing can help predict eruptions but only if the magma system is well understood first.
How do greenhouse gases and water circulate from minerals deep below Earth’s surface into the atmosphere and oceans—and then back again? Our understanding continues to evolve.
New research identifies temperature, moisture, and soil fungi as important factors in influencing how biogenic volatile organic compounds cycle between plants and the atmosphere.
Planktonic foraminifera and sea snail numbers swell from April to June in the Barents Sea, but contrary to predictions, the organisms do not appear to be affected directly by high methane levels.
Laacher See volcano is quiet, but gas bubbles rising through the overlying lake are a reminder of its potential hazard. Scientists took a close look at the bubbles to test eruption monitoring methods.
High levels of carbon dioxide and hydrogen sulfide emitted by volcanic outgassing caused a deadly accident near Rome, Italy, in 2011, geoscientists have shown.
In lab experiments and models, researchers uncover how ash can affect the standing shock waves of erupting volcanoes. Their findings may lead to new predictions of volcanic ash hazards.
An international research group recorded the acoustic signatures of gas bubbles rising from a hydrothermal vent field to gather clues about greenhouse gases escaping into the atmosphere.
A NASA stereo-imaging mission called TWINS continues to push the boundaries of what we know about the region of space close to Earth.
