Geoscientists develop technology to improve forecasting of earthquakes, tsunamis
University of South Florida geoscientists have successfully developed and tested a new high-tech shallow water buoy that can detect the small movements and changes in the Earth’s seafloor that are often a precursor to deadly natural hazards, like earthquakes, volcanoes and tsunamis.

Using the past to unravel the future of Arctic wetlands
The study found that under 21st century warming conditions and with adequate moisture, certain Arctic wetlands may transition into peatlands, creating new natural carbon storage systems and to some extent mitigating carbon losses from degrading peatlands in southern regions.

First evidence of planet-wide groundwater system on Mars
Mars Express has revealed the first geological evidence of a system of ancient interconnected lakes that once lay deep beneath the Red Planet’s surface, five of which may contain minerals crucial to life.

Climate change could make corals go it alone
Climate change is bad news for coral reefs around the world, with high ocean temperatures causing widespread bleaching events that weaken and kill corals. However, new research finds corals with a solitary streak – preferring to live alone instead of in reef communities – could fare better than their group-dwelling relatives.

Two- to three- fold increase in heatwave occurrence and severity seen directly in UK temperature records
A two- to three-fold increase in heatwave activity in the United Kingdom since the late 19th century has been identified in a new analysis of historical daily temperature data.

New research shows significant decline of glaciers in Western North America
The first comprehensive assessment of glacier mass loss for all regions in western North America (excluding Alaskan glaciers) suggests that ice masses throughout western North America are in significant decline: glaciers have been losing mass during the first two decades of the 21st century.

Fort McMurray homes have normal levels of indoor toxic substances following wildfire, new study reveals
Researchers have examined dust from homes in Fort McMurray in Canada for evidence of harmful toxins left in the aftermath of the devastating 2016 wildfire. Their study reveals normal levels of contaminants that are comparable to homes across Canada, and so far, no evidence of long-term health risks from fire-ash exposure in residents’ homes

Colorado’s Lake Dillon is warming rapidly
The surface waters of Lake Dillon, a mountain reservoir that supplies water to the the Denver area, have warmed by nearly 5 degrees Fahrenheit (2.5 degrees Celsius) in the last 35 years, which is twice the average warming rate for global lakes. Yet surprisingly, Dillon does not show adverse environmental changes, such as nuisance algal blooms, often associated with warming of lakes.

Listen: The sound of electromagnetic energy moving between Saturn, Enceladus
New research from Cassini’s up-close Grand Finale orbits shows a surprisingly powerful and dynamic interaction of plasma waves moving from Saturn to its moon Enceladus and its rings.

New study offers new evidence for how the Adirondack Mountains formed
The formation mechanism of the Adirondack Mountains in upstate New York has long posed a geologic mystery. A few mechanisms have been proposed, but until recently tools for evaluating them were not in place. Now, using an advanced seismic imaging method and data available only in the past five years, researchers have constructed a detailed model of the tectonic plate – the crust and the uppermost rigid mantle of the lithosphere under the northeast United States – down to about 62 miles (100 kilometers), in which they discovered a “pillow” of low-density, relatively light rock material. They say a column of this lighter material appears to have squeezed up under the Adirondacks, possibly expanded by heat, to form the dome-shaped mountains.
