Using precise measurements from state-of-the-art satellite-based radar that can detect the land surface rise and fall with millimeter accuracy, an ASU research team has, for the first time, tracked the entire California coast's vertical land motion. They've identified local hotspots of the sinking coast, in the cities of San Diego, Los Angeles, Santa Cruz and San Francisco, who will be at a higher flooding risk during the decades ahead of projected sea-level rise.
A study by scientists from the University of Southampton has examined the chances of catching COVID-19 in a train carriage carrying an infectious person.
Coastal flooding across the world is set to rise by around 50 per cent due to climate change in the next 80 years, endangering millions more people and trillions of US dollars more of coastal infrastructure, new research shows.
An international team discovered a previously unrecognized ocean current that transports water to one of the world's largest 'waterfalls' in the North Atlantic Ocean: the Faroe Bank Channel Overflow into the deep North Atlantic
The India-Asia collision is an outstanding smoking gun in the study of continental collision dynamics. Yuan and colleagues hypothesize that the Tethyan Himalaya terrane rifted from India after ~75 Ma, generating the North India Sea. They further document a new two-stage continental collision, first at ~61 Ma between the Lhasa and Tethyan Himalaya terranes, subsequently at ~53-48 Ma between the Tethyan Himalaya terrane and India, diachronously closing the North India Sea from west to east.
Group of researchers, from six countries, identified, genetically and morphologically, a new population of rats (Microcebus) that inhabit the same forests as another usual species previously described. The research investigation was published in two scientific articles, in Systematic Biology and in the American Journal of Primatology, and studied the smallest nocturnal primates. The work highlights the consequences of deforestation and habitat removal, accelerating an extinction of species yet to be described.
In a recent study, researchers from The University of Texas at Austin show that a natural record - sediments packed together at basin margins - offers scientists a powerful tool for understanding the forces that shaped our planet over millions of years, with implications on present day understanding.
An international team of researchers has published the most detailed submarine map of the Artic Ocean. The study, which counts on the participation of the experts Miquel Canals, José Luis Casamor and David Amblàs, from the Consolidated Research Group on Marine Geosciences of the University of Barcelona, has been published in Nature's journal Scientific Data.
A sonic boom-like seismic phenomenon of supershear rupture occurred during the 2018 Palu earthquake in Indonesia. University of Tsukuba researchers investigated the relationship between this phenomenon and the complex geometry of the Palu-Koro fault. An "inchworm-like" pattern of repeated rupture deceleration and acceleration along the fault was detected, associated with bends in the fault trace. This slip evolution may have enhanced the propagation of supershear rupture and contributed to the generation of the 2018 Palu tsunami.
Ciais and colleagues obtained the first bottom-up global land carbon budget from the sum of regional estimates, combining inventories with lateral transfers from the trade of wood and food products and the export of dissolved carbon by rivers to the oceans. Carbon being moved away from ecosystems by lateral fluxes and emitted by fires and as reduced compounds is a large fraction of primary production inputs, implying a smaller CO2 emission from soil microbial decomposition.
