Flooding from torrential rains caused by cyclones and monsoonal storms, as well as other catastrophic events, are responsible for moving huge amounts of fresh wood to a watery grave deep under the ocean, according to a new study by Earth scientists from an international team including researchers at the University of Southern California, Los Angeles, the Woods Hole Oceanographic Institution, the Chinese Academy of Sciences, Western Washington University and the Centre de Recherches Pétrographiques et Géochimiques, CNRS, Université de Lorraine. The research, published in the Proceedings of the National Academy of Sciences, shows the first-ever evidence that trees may travel thousands of miles from their mountain homes to settle in the vast sediments extending under the sea from river mouths.
