The entire contiguous U.S. has experienced massive urban expansions and the Atlantic Coast shows outstandingly high rates. Urban expansion has substantially squeezed the space of tidal flats and affected surrounding environments. In new urban areas, tidal flats have undergone considerable degeneration with more significant patterns as they get closer to new urban locations. Tidal flats protect against the ocean’s destructive powers such as hurricanes. Without some inland spaces to move around, they will likely disappear, which will have dire consequences for beachfront communities.
A new study led by Georgia Tech shows that water underneath glaciers may surge due to thinning ice sheets — a dangerous feedback cycle that could increase glacial melt, sea level rise, and biological disturbances.

The latest headlines from the Food and Water Safety channel on Newswise.
New research from Binghamton University, State University of New York links chemical changes in seawater to volcanic activity and changes.
Arctic sea ice, an important component of the Earth system, is disappearing fast under climate warming. Summer sea ice is anticipated to vanish entirely within this century.
Geoscientists have long thought that water – along with shallow magma stored in Earth’s crust – drives volcanoes to erupt. Now, thanks to newly developed research tools at Cornell, scientists have learned that gaseous carbon dioxide can trigger explosive eruptions.
Lawrence Livermore National Laboratory (LLNL) has partnered with another national lab and a seismic instrumentation monitoring company to develop a physics-based seismic-forecasting software platform to help operators and regulators better understand and manage seismic hazards at carbon storage sites.
Catastrophic dynamic rock failure (rockburst) is one of the most challenging problems existing in the fields of civil tunnelling and mining. The outcomes of this study advance the understanding of rockburst in the industry, by defining the magnitude of energy that is required to cause a burst in a given geotechnical and mining domain and its release mechanisms.
Gems' unique elemental composition and atomic orientation act as a fingerprint, enabling researchers to uncover the stones’ past, and with it, historical trade routes. In AIP Advances, Khedr et al. employ three modern spectroscopic techniques to rapidly analyze gems found in the Arabian-Nubian Shield and compare them with similar gems from around the world. The authors identified elements that influence gems’ color, differentiated stones found within and outside the region, and distinguished natural from synthetic.
Although the location of St. Croix is perfect for a VLBA antenna, the island poses significant challenges for using and maintaining a radio antenna. The St. Croix dish is located on the eastern side of the island, almost at sea level. So it is constantly bombarded by salt air, ocean rains, and even the occasional tropical storm.
Steamboat Geyser’s spray slowly fossilizes the trees it lands on – preserving the geyser’s past and providing a glimpse into Steamboat’s uncertain future.
An international research team, led by Professor Dorthe Dahl-Jensen of the University of Manitoba and University of Copenhagen, has reached a significant milestone by drilling through 2670 m of ice on the North Greenland Ice Stream and reaching bedrock after seven long years.
Earth is truly unique among our Solar System’s planets. It has vast water oceans and abundant life. But Earth is also unique because it is the only planet with plate tectonics, which shaped its geology, climate and possibly influenced the evolution of life.
U seismologists are analyzing decades of seismic data in the hope of discerning the significance of earthquake swarms in a geologically complex region known as a geothermal hotspot and for recent—geologically speaking—volcanism.

A large portion of Greenland was an ice-free tundra landscape — perhaps covered by trees and roaming wooly mammoths — in the recent geologic past (about 416,000 years ago), according to a new study in the journal Science. The results shed light on the stability of the Greenland ice sheet over the last two and a half million years. Instead, moderate warming (mean global temperatures of 1 to 1.5°C above pre-industrial values) that lasted 30, 000 years, from 420,000 to 390,000 years ago, led to significant melting (at least 20% of the total Greenland Ice sheet volume).
