The Lasting Legacy of Phosphorus Buried in Lakes
Research at an experimental lake suggests that phosphorus inputs from runoff may affect the health of aquatic ecosystems long after external additions of the nutrient are reduced.

From Blowing Wind to Running Water: Unifying Sediment Transport
Laboratory experiments and grain-scale computer simulations during the past decade have led to a more universal understanding of flow-driven sediment transport across flows in oil, water, and air.

Tracing the Past Through Layers of Sediment
Signals in layers of sedimentary rock hint at climates and ecosystems come and gone. Understanding this history can help us forecast the future, but challenges abound.

Sediments May Support the Mediterranean Megaflood Hypothesis
Millions of years ago, the Mediterranean Sea may have evaporated. A newly identified body of sediments could have been deposited by the giant flood that refilled the basin.

Submarine Rivers of Sediment
Turbidity currents move suspended sediment into the ocean. In general, the more sediment, the stronger the turbidity current, but one process may generate turbidity currents from very dilute rivers.

Oceans Vented Carbon Dioxide During the Last Deglaciation
A new boron isotope record from South Pacific marine sediments offers a more complete picture of ocean-atmosphere carbon dioxide exchange during the late Pleistocene.

New Study Shifts Paradigm of Coastal Sediment Modeling
A new model improves predictions for sediment movement in vegetated shoreline zones and reveals a universal predictor that could change the understanding of coastal landscape evolution.
