New research reconstructs the Bering Strait’s flooding history, raising surprising questions about human migration and how ice sheets form.
Decoding the Secrets of Shifting Sediments
In the small-scale details of grain shape, researchers have found a new way to understand how sediment flows in a river, a process shaping Earth’s landscapes.
What Electrons Can Tell Us About the Speed of Sand
A new sediment tracer uses the interactions between radiation, charge, and the Sun to uncover the hidden transport histories of sand grains.
Sedimentos lacustres registran el legado del carbón de Carolina del Norte
Los lagos contaminados con cenizas de carbón se encuentran en áreas residenciales y recreativas, provocando preocupaciones por la salud de los residentes locales y los ecosistemas.
Roughed-Up Hillsides Reveal Tree-Toppling Winds
Researchers are reading pockmarks in the forest floor to study the uprooting of trees in southern Indiana and estimate how fast winds howled through the forest in the past.
New Mechanism for “Giant” Greigite Growth in Deep-Sea Sediments
Understanding greigite formation pathways in sediments is a prerequisite for assessing the marine iron-sulfur-carbon cycle and yield reliable near-syn-sedimentary paleomagnetic records.
Understanding Enhanced Arsenic Pollution in Shallow Lakes
A new study explains why the arsenic that has accumulated in lake bottom sediments is more harmful to the lake ecosystems in shallow lakes.
Did a Chaotic Climate Drive Human Evolution?
A new 620,000-year climate record from East Africa reveals dramatic swings between wet and dry conditions that may have influenced human evolution.
Disentangling River Water Turbidity and its Flow
A new study shows why fine sediments in rivers are not simply proportional to the water flow across the United States.
Warming and Agitation Intensify Seagrass Meadow Carbon Fluxes
Carbon dioxide emissions surge in sediments when temperature and agitation increase, both of which are likely to continue rising in degraded Mediterranean seagrass meadows.
