Autopsy of a eruption: Linking crystal growth to volcano seismicity

A forensic approach that links changes deep below a volcano to signals at the surface is described by scientists from the University of Bristol in a paper published May 24 in Science. The research could ultimately help to predict future...

LiDAR technology reveals faults near Lake Tahoe

Results of a new U.S. Geological Survey study conclude that faults west of Lake Tahoe, Calif., referred to as the Tahoe-Sierra frontal fault zone, pose a substantial increase in the...

Beetle-infested pine trees contribute more to air pollution and haze in forests

The hordes of bark beetles that have bored their way through more than 6 billion trees in the western U.S. and British Columbia since the 1990s do more than damage...

Seagrasses can store as much carbon as forests

Scientists take samples of seagrass beds at NSF's Florida Coastal Everglades LTER site.Seagrasses are a vital part of the solution to climate change and, per unit area, seagrass meadows can store up to twice as much carbon as the world's temperate and...

Toxic mercury, accumulating in the Arctic, springs from a hidden source

This is the Lena River delta. The Lena is one of several major rivers that flows northward into the Arctic Ocean.Environmental scientists at Harvard have discovered that the Arctic accumulation of mercury, a toxic element, is caused by both atmospheric forces and the flow of circumpolar rivers that carry the...

New study by WHOI scientists provides baseline measurements of carbon in Arctic Ocean

WHOI researcher David Griffith and his colleagues conducted their fieldwork in 2008 aboard the Canadian Coast Guard icebreaker Louis S. St. Laurent. At two different spots in the Canada Basin, an area northwest of the Canadian coast, they gathered samples from 24 depths ranging from the surface to the ocean floor 3,800 meters (roughly 12,500 feet) below.Scientists from the Woods Hole Oceanographic Institution (WHOI) have conducted a new study to measure levels of carbon at various depths in the Arctic Ocean. The study, recently published in...

Pollution teams with thunderclouds to warm atmosphere

Pollution is warming the atmosphere through summer thunderstorm clouds, according to a computational study published May 10 in Geophysical Research Letters. How much the warming effect of these clouds offsets...

Sumatra faces yet another risk -- major volcanic eruptions

The early April earthquake of magnitude 8.6 that shook Sumatra was a grim reminder of the devastating earthquakes and tsunami that killed tens of thousands of people in 2004 and...

Chocolate and diamonds: Why volcanoes could be a girl's best friend

Kimberlite volcanoes, the primary source of diamonds, contain pelletal lapilli -- enigmatic magma-coated clasts. These are generated deep in the volcanic vent by a granulation process analogous to that commonly used in coating chocolates, drugs and fertilizers.Scientists from the University of Southampton have discovered a previously unrecognised volcanic process, similar to one that is used in chocolate manufacturing, which gives important new insights into the dynamics...

USF study: Common fungicide wreaks havoc on freshwater ecosystems

Chlorothalonil, one of the world's most common fungicides used pervasively on food crops and golf courses, was lethal to a wide variety of freshwater organisms in a new study, University...

Statistical analysis projects future temperatures in North America

For the first time, researchers have been able to combine different climate models using spatial statistics -- to project future seasonal temperature changes in regions across North America.

El Niño weather and climate change threaten survival of baby leatherback sea turtles

When leatherback turtle hatchlings dig out of their nests buried in the sandy Playa Grande beach in northwest Costa Rica, they enter a world filled with dangers. This critically endangered species faces threats that include egg poaching and human fishing...

Geological record shows air up there came from below

The influence of the ground beneath us on the air around us could be greater than scientists had previously thought, according to new research that links the long-ago proliferation of...

Track Atlantic bluefin tuna to learn migration, habitat secrets

Fisheries oceanographer Molly Lutcavage tags a juvenile bluefin tuna with a pop-up satellite antenna.New fish-tagging studies of young bluefin tuna in Atlantic waters off New England by researchers at the University of Massachusetts Amherst are offering the first fishery-independent, year-round data on dispersal...

Nea Kameni volcano movement captured by Envisat

Archived data from the Envisat satellite show that the volcanic island of Santorini has recently displayed signs of unrest. Even after the end of its mission, Envisat information continues to...

Earth's water cycle intensifying with atmospheric warming

A clear change in salinity has been detected in the world's oceans, signalling shifts and an acceleration in the global rainfall and evaporation cycle.

Stanford scientists document fragile land-sea ecological chain

The researchers found a link between replacing native trees with non-native palms and the health of the manta ray population off Palmyra Atoll in the Pacific.Douglas McCauley and Paul DeSalles did not set out to discover one of the longest ecological interaction chains ever documented. But that's exactly what they and a team of researchers...

1,000 years of climate data confirms Australia's warming

In the first study of its kind in Australasia, scientists have used 27 natural climate records to create the first large-scale temperature reconstruction for the region over the last 1000...

Manmade pollutants may be driving Earth's tropical belt expansion

Robert Allen is an assistant professor of Earth sciences at UC Riverside.Black carbon aerosols and tropospheric ozone, both humanmade pollutants emitted predominantly in the Northern Hemisphere's low- to mid-latitudes, are most likely pushing the boundary of the tropics further poleward in...

Ancient tree-ring records from Southwest US suggest today's megafires are truly unusual

A tree ring shows the pattern of fire scars from 1700 to 1979. As is typical of tree rings, fire scars stop around 1900 due to a century of fire suppression.Today's mega forest fires of the southwestern U.S. are truly unusual and exceptional in the long-term record, suggests a new study that examined hundreds of years of ancient tree ring...

UMD finding may hold key to Gaia hypothesis

Is Earth really a sort of giant living organism as the Gaia hypothesis predicts? A new discovery made at the University of Maryland may provide a key to answering this...

New species of fish in Sweden

This is a reticulated dragonet, a new species in Sweden, well-camouflaged against the seabed in the Väderöarna.Reticulated dragonet have been found in Väderöarna -- "Weather Islands" -- off the west coast of Sweden. It is not often that a new species of fish is discovered in...
