Researchers found large impacts can fracture a planet's crust, introducing porosity that increases its potential for life. This discovery has implications for early Earth and Mars, suggesting life could have survived in pore spaces during intense impact periods.
The International Bathymetric Chart of the Southern Ocean v2 provides the most detailed seafloor map of the region, with new data covering twice the area of its predecessor. This chart will help scientists better understand ocean currents and climate change.
A new study led by Smithsonian volcanologist Dan Rasmussen finds that water content in magma is a significant factor controlling its storage depth. The research provides crucial insights into the physics of magma storage beneath volcanoes, which can aid in predicting volcanic eruptions.
A study in the journal Geology explores the formation of rifts as tectonic plates pull apart, finding that slow plate movement is the primary driver. The research focuses on a newly formed rift in Iceland, where magma did not play a key role in its creation.
A submersible robot will explore three of Greenland's glaciers with a remotely operated vehicle Nereid Under Ice (NUI), mapping seafloor topography and retrieving sediment cores to study moraines and their impact on glacier stability. The mission aims to improve model projections for future sea level rise.
Researchers have uncovered the truth behind the missing volatiles in meteorites, revealing a massive shockwave phenomenon that stripped elements from planetary building blocks. This finding has significant implications for our understanding of Earth's geochemical evolution and the Solar System's youth.
Researchers observed diverse aquatic biota in post-flood communities, with changes in flow dynamics and water chemistry supporting biological adaptation. The study highlights the role of floods in shaping floodplain ecosystems.
A study published in Geology suggests that ancient glassy rocks in the Atacama Desert, Chile, were created by a cometary fireball explosion around 12,000 years ago. The glasses contain minerals with signatures similar to those found in comet samples, providing evidence of an extraterrestrial origin.
The Dartmouth Engineering team will conduct research on planetary science relating to icy planets' geophysics and astrobiology, aiming to understand the nature of these worlds and their habitability. The project will provide valuable tools for interpreting measurements taken by future missions.
The GSA Annual Meeting technical session 'Geomorphology of the Anthropocene' brings together experts to address human impacts on Earth's systems. Research studies investigate influences such as indigenous culture and dams, with a focus on defining the Anthropocene's temporal and spatial scales.
