Abstract:

The overall goal of the STRATAFORM project is to advance our understanding of the development of stratigraphic sequences on continental shelves and slopes. Part of this understanding comes from detailed measurements of the characteristics of event-scale strata that may be formed or modified during river floods or intense storms. The research described below is directed toward providing data on the grain-size characteristics of event-scale strata that can be related directly to storms or floods observed during STRATAFORM. This information will provide a yardstick with which to examine older prehistoric sediment units in long cores with the objectives of understanding modes of deposition, strata preservation and, potentially, any long-term changes in the local climate or river discharge. Additionally, the sediment data are being used in conjunction with measurements of bottom boundary layer flows to validate and provide inputs and ground-truth for sediment transport and strata development models.
