Abstract:

The ultimate objective of this research program is to obtain a predictive understanding of the physical and biological processes responsible for the formation, alteration and preservation of marine sedimentary deposits. The general approach of this research program is the development and testing of theory mainly through field observations and measurements. This is a proposal, within the STRATAFORM Shelf Program, to study the formation, post-depositional alteration and preservation of flood deposits on the Pacific Northwest continental margin. Five related activities are being pursued 1 continuation of time series measurements of the areal distribution and small-scale properties of the 1995 and 1997 flood deposits, 2 statistical analysis of the small-scale spatial variability of flood bed thickness and geometry at stations K60 and S60, 3 x-radiographic examination of piston cores for past flood deposits, 4 testing of simple conceptual ideas of event layer alteration and preservation using the above data sets, and 5 examination of patterns of sediment accumulation and event layer preservation offshore of other Pacific Northwest rivers.
