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.

Scientists decipher the magma bodies under Yellowstone
Using supercomputer modeling, scientists have unveiled a new explanation for the geology underlying recent seismic imaging of magma bodies below Yellowstone National Park.

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.

New study finds space radiation is increasingly more hazardous
As future missions look to travel back to the moon or even to Mars, new research cautions that the exposure to radiation is much higher than previously thought and could have serious implications on both astronauts and satellite technology.

New study helps explain Greenland glaciers’ varied vulnerability to melting
Using data from NASA missions observing Earth, researchers at the University of California, Irvine have created new maps of the bed topography beneath a score of glaciers in southeast Greenland, thereby gaining a much better understanding of why some are undergoing rapid retreat and others are relatively stable.

Underwater volcano behavior captured by timely scientific expedition
Researchers got a rare opportunity to study an underwater volcano in the Caribbean when it erupted while they were surveying the area. The research, published online in the journal Geochemistry, Geophysics, Geosystems, a journal of the American Geophysical Union, provides new insight into the little-studied world of underwater volcanoes. It investigated a volcano named Kick-‘em-Jenny (KeJ), which is thought to be named after the turbulent waters nearby.
