The Journal of Geology, Vol. 58, No. 2 (Mar., 1950), pp. 91-127 (42 pages) Some types of graded bedding, especially minor or isolated occurrences and varved "clays," can be readily accounted for by ...

Boulder, Colo., USA: Benthic plastic litter is a main source of pollutants in oceans, but how it disperses is largely unknown. This study by Guangfa Zhong and Xiaotong Peng, published today in Geology ...

The Coordinated Canyon Experiment yielded many other firsts in the field of marine geology: The highest velocity turbidity-current flow ever measured instrumentally (8.1 meters/second). The first ...

Turbidity currents have historically been described as fast-moving currents that sweep down submarine canyons, carrying sand and mud into the deep sea. But a new paper in Nature Communications shows ...

A new study from the University of Manchester and the United Kingdom's National Oceanography Centre has uncovered a hidden transport system for microplastics. Deep-sea "avalanches," or turbidity ...

Geology papers published 17 Mar. 2014 cover (1) modeling of seabed turbidity currents; (2) a large earthquake at Lake Vättern, Switzerland, about 11,500 years ago; (3) genesis of high-grade gold at ...

Scientists have measured an underwater mud avalanche that lasted two days and crossed more than 1,100 kilometers across the Atlantic Ocean floor. The sediment avalanche, or turbidity current as the ...

Durham University scientists have made a groundbreaking discovery in marine geoscience, revealing unprecedented insights into the dynamics of Earth's longest runout sediment flows. By using seabed ...

One of the mysteries of the ocean is the long, deep gorges that wind across the continental shelves like submerged river valleys. Oceanographers thought at first that they were really valleys cut by ...

Turbidity currents in submarine canyons often involve large-scale movement of the seafloor. This discovery could help ocean engineers avoid damage to pipelines, communications cables, and other ...
