Factors Influencing the Temporal and Spatial Variability of the Textural Characteristics of Event-Scale Strata on the Eel Shelf.

摘要

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 and intense storms. Our research 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 provides a "yardstick" with which to examine older sediment units in long cores with the objectives of understanding modes of deposition, strata preservation and, potentially, any variability or long-term trends in climate and resulting river discharges.
