How mantle hydration changes over the lifetime of a subduction zone
Because of interactions with Earth's hot mantle, water-logged oceanic plates release water as they slide beneath less dense overriding plates in subduction zones. This water rises and hydrates the mantle above it, contributing to the formation of vol.....»»
Upgraded atomic force microscope captures 3D images of calcite dissolving
Understanding the dissolution processes of minerals can provide key insights into geochemical processes. Attempts to explain some of the observations during the dissolution of calcite (CaCO3) have led to the hypothesis that a hydration layer forms, a.....»»
We must stop evictions to end chronic homelessness, says researcher
Homelessness, a crisis that affects about 11% of Canadians in their lifetime, often begins with eviction. Once a person or family is evicted, they are set on a trajectory that can lead to chronic homelessness as they try to find affordable housing in.....»»
Algorithm raises new questions about Cascadia earthquake record
The Cascadia subduction zone in the Pacific Northwest has a history of producing powerful and destructive earthquakes that have sunk forests and spawned tsunamis that reached all the way to the shores of Japan......»»

Exoplanets may contain more water than previously thought
We know that the Earth has an iron core surrounded by a mantle of silicate bedrock and water (oceans) on its surface. Science has used this simple planet model until today for investigating exoplanets—planets that orbit another star outside our sol.....»»
Geophysicists find link between seismic waves called PKP precursors and strange anomalies in Earth"s mantle
For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth's lower mantle scatter incoming seismic waves, which return to the surface as PKP waves at differing speeds......»»
Research team finds evidence of hydration on the asteroid Psyche
Using data from NASA's James Webb Space Telescope, a Southwest Research Institute-led team has confirmed hydroxyl molecules on the surface of the metallic asteroid Psyche. The presence of hydrated minerals suggests a complex history for Psyche, impor.....»»
New parameter enhances insights into the evolution of mantle"s redox states
The oxygen fugacity (fO2) of the mantle controls the speciation and mobility of volatiles within it, influencing the composition of volatiles released during mantle-derived magmatic activity, and thereby regulating the composition of the atmosphere......»»
Early improvement of sandy habitat led to origin of agriculture in the farming-pastoral zone of northern China: Study
The beginning of agriculture is one of the most significant events in human history. The origin and spread of agriculture accelerated the development of human society and economy and fundamentally altered humans' role in the Earth's ecosystem. This a.....»»
The biggest-ever sample of core material from Earth"s mantle could have valuable clues into the origins of life
If you were to slice through it, you would see the Earth is divided into distinct layers. On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer. Then, enclosed within the mantle is the innermost metallic c.....»»
Veterinarian says owners should be aware of the risks of letting their dogs drink from public water sources
When taking your dog for a walk during the scorching summer heat, it may be tempting to allow your dog a few laps from the nearest drinking station in order to cool off. However, shared hydration sources can potentially have dire effects for your bel.....»»
Recovery of rocks that originated in Earth"s mantle could reveal secrets of planet"s history
Scientists have recovered the first long section of rocks that originated in the Earth's mantle, the layer below the crust and the planet's largest component......»»

Water delivered to the mantle by aluminum enriched hydrated slabs?
Dense hydrous magnesium silicates (DHMSs) are generally considered as primary water carriers from the shallow lithosphere to the deep mantle transition region (MTR; 410–660 km in depth). Among DHMSs, Superhydrous phase B (hereafter, SuB) holds the.....»»

Researchers use vibrations from traffic to measure underground soil moisture
Caltech researchers have developed a new method to measure soil moisture in the shallow subterranean region between the surface and underground aquifers. This region, called the vadose zone, is crucial for plants and crops to obtain water through the.....»»
Gulf of Mexico "dead zone" larger than average, scientists find
NOAA-supported scientists have announced that this year's Gulf of Mexico "dead zone"—an area of low to no oxygen that can kill fish and marine life—is approximately 6,705 square miles, the 12th largest zone on record in 38 years of measurement. T.....»»
Imaging below the surface reveals one of Los Angeles"s webs of faults
A major fault is often surrounded by a web of secondary faults created as the forces that cause slip deform nearby rocks. This damage zone can act as a record of fault activity, but what we can learn from it—such as how the fault may behave during.....»»
