Abrupt Climate Shifts Change the Latitudes of Storm Activity
A new 6500-year construction of storms combined with other paleo-storm records finds abrupt changes in the Atlantic Ocean circulation impact the latitudinal preference of storm activity.

Sediment Layers Pinpoint Periods of Climatic Change
Researchers studying sediment cores from the Gulf of Alaska have pinpointed when the Cordilleran Ice Sheet, now extinct, disgorged icebergs into the Pacific Ocean.

Experimenting with Underwater Sediment Slides
Sediment-laden currents caused by breaching flow slides are hazardous to flood defenses and seabed infrastructure. New research shows that these phenomena must be accounted for in erosion simulations.
