Satellites could further help mitigate river floods

Now, a new study in Geophysical Research Letters, a journal of the American Geophysical Union, analyzes what it would take for river-observing satellites to become an even more useful tool to mitigate flood damage and improve reservoir management globally in near real-time.

New study finds glacial evidence for abrupt climate change

Results from a new study indicate that the physical impact of abrupt climate change in Britain, Ireland and maritime Europe may be markedly different from previous perceptions of these events.

Tohoku tsunami impacted home-building habits of eco-engineer heart urchins

In a new study published in the Journal of Geophysical Research: Oceans, a journal of the American Geophysical Union, researchers explore how tsunamis impact shallow marine environments, also known as benthic environments, and the small, burrowing animals that dwell there.

Early climate action has big effect on rising sea levels

Rising sea levels will accelerate this century and beyond, exposing hundreds of millions of people to flooding and other coastal hazards by the year 2300. But acting early to lower greenhouse gas emissions can slow that rise, say scientists in two new studies in Earth’s Future, an open access journal published by the American Geophysical Union.

Infrasound recordings give scientists a peek inside volcano’s plume

High-resolution recordings of the powerful infrasound waves generated by an eruption at Ecuador’s Tungurahua volcano have given scientists a rare view inside the activity at the volcano’s mouth. The acoustic waves generated by the July 2013 eruption were one of the most powerful volcanic infrasound recordings ever captured. The low-frequency infrasound waves from the eruption are too low for human ears to hear but were as powerful as waves one meter (three feet) away from a jet engine.

Wider coverage of satellite data better detects magma supply to volcanoes

Using satellite imaging, researchers for the first time identified a major magma supply into a reservoir extending almost two miles from the crater of a volcano in Nicaragua.

Study reveals potential stability of ocean processes despite climate change

In a new study published in Global Biogeochemical Cycles, a journal of the American Geophysical Union, Pearse Buchanan, a scientist at the Institute for Marine and Antarctic Studies at the University of Tasmania, and his team integrated new, dynamic ways of representing marine ecosystem processes in ocean models. In applying them, they found that a more realistic representation of the marine ecosystem helped the ocean to take up and store carbon at similar rates regardless of global changes in physical properties, like temperature, salinity and circulation.

August 2017 SpaceX rocket launch created large circular shock wave

The unusual trajectory the SpaceX Falcon 9 rocket took when delivering a Taiwanese satellite into orbit last August created an atmospheric shock wave four times bigger than the area of California, a new study finds.

Wind, sea ice changes suggest climate change in western Arctic

A major shift in western Arctic wind patterns occurred throughout the winter of 2017 and the resulting changes in sea ice movement are possible indicators of a changing climate, according to authors of a new study.
