Volcanic craters act as giant horns that emit intense low-frequency sounds. Changes in this infrasound may be used to track rising lava lakes and identify signals of future eruptions.Read More »Geology & Geophysics
Continental arcs are a major player in global carbon dioxide emissions, but quantifying that relationship is hard. A new study accepts the challenge on a global scale over 750 million years.Read More »Biogeosciences
Dissolved organic matter supports aquatic food webs and holds as much carbon as the atmosphere. A new study tracks which sources and processes play the biggest role in coastal systems.Read More »Geochemistry, Mineralogy, Volcanology
Roughly 1,500 years ago, the Tierra Blanca Joven eruption blanketed Central America in ash and likely displaced Maya settlements, new research shows.Read More »Ocean Sciences
The society that led scientists through some of the most groundbreaking discoveries of the past century looks ahead to the next challenges with a Centennial symposium in late June.Read More »Geochemistry, Mineralogy, Volcanology
A new framework for understanding the suite of processes acting on marine particulate trace metals exemplifies how alternative analyses can maximize the information that large data sets provide.Read More »Hydrology, Cryosphere & Earth Surface
Hydrous silica-rich magmas can degas through connected bubble pathways when as little as 20% crystals are present, influencing transitions from explosive, Vulcanian-style eruptions to lava effusion.Read More »
