Textural analysis of marine sediments at the USGS Woods Hole Science Center; methodology and data on DVD
Lawrence J. Poppe, S. Jeffress Williams, Valerie F. Paskevich
2006, Conference Paper, Proceedings of the Eighth Federal Interagency Sedimentation Conference
Marine sediments off the eastern United States vary markedly in texture (i.e., the size, shape, composition, and arrangement of their grains) due to a complex geologic history. For descriptive purposes, however, it is typically most useful to classify these sediments according to their grain-size distributions. In 1962, the U.S. Geological...
