A Sharper Look at the World’s Rivers and Catchments
Digital hydrographic maps have transformed global environmental studies and resource management. A major database update will provide even clearer and more complete views of Earth’s waterways.
Mortality of Seagrass Meadows May Not Kill Their Methane Release
New research indicates that seagrasses continue to release methane even after they die, complicating blue carbon initiatives.
Moving Earthquake-Generated Sediment Through a Landscape
Ten years after the Wenchuan earthquake, most of the new sediment it produced remained on the landscape, indicating a long recovery time.
Cuando los ríos están contaminados, las inundaciones son solamente el primer problema
A medida que las inundaciones aumentan en frecuencia e intensidad, los productos químicos enterrados en los sedimentos de los ríos se convierten en “bombas de tiempo” que esperan activarse.
How Does Sand Move? New Observations Challenge Prevailing Formulas
Research in the Azores finds a discrepancy between field observations of sediment transport and predictions made with commonly used mathematical formulas.
Sediments Suggest Vikings May Have Been the First to Settle the Azores
A multidisciplinary team studying lake sediments and climate change found evidence that the archipelago was inhabited 700 years earlier than historical sources claim.
Mammoths Lost Their Steppe Habitat to Climate Change
Ancient plant and animal DNA buried in Arctic sediments preserve a 50,000-year history of Arctic ecosystems, suggesting that climate change contributed to mammoth extinction.
New Theory Connects Tree Uprooting and Sediment Movement
Tree throw from extreme wind events plays an important role in the movement of sediment and erosion on forested hillslopes. A new theory offers a novel way to measure its impact.
Himalayan Tectonics in the Driver’s Seat, Not Climate?
Earth’s oscillating climate is a natural guess to explain cyclic patterns in erosion, but new sediment data suggests that cyclicity may emerge from tectonic processes adding material to the Himalaya.
