Our long-term objective within the STRATAFORM research program is to investigate the processes that lead to the genesis, modification, and burial of fine-scale stratification in continental shelf sediments. Our approach is to a sample the continental shelf immediately after events and at closely spaced intervals thereafter, to monitor the shorter term months to years changes that modify the distribution and character of event layers and b examine the preserved stratigraphy in the upper few meters of the seabed to examine the characteristics and fate of event layers over the longer term 10 - 1,000 years. The objectives of this project include 1 to identify the results of major flood and storm events on the sedimentology and stratigraphy on the inner continental shelf, 2 to investigate the importance of the inner shelf for the longer term preservation of strata initially deposited during events and the relative contributions of physical and biological reworking to the postdepositional modification of event layers, and 3 to use data from the upper few meters of the seabed to examine the along- and across-shelf variability of event layer character and preservation as applied over decades to thousand-year time scales.
