“…Their origins have been linked to river incision, subaerial erosion, turbidity current erosion, faulting and activity of benthic fauna in marine environments (Shepard and Dill, 1966;Shepard, 1981;Belderson and Kenyon, 1976;Twichell and Roberts, 1982). May et al (1983) emphasized that several factors played a part in originating, altering and maintaining the canyons. These factors include tectonics, eustacy and sedimentary processes operating over a long period of time.…”

LONG-TERM GOALS My goal within the EuroSTRATAFORM program is to understand the creation of the preserved stratigraphic record on continental shelves and slopes as the product of physical processes acting with spatial and temporal heterogeneities. I have been using numerical models to provide insight into the formation and preservation of stratigraphic sequences at margins. My goal has been to obtain a quantitative understanding of the interactions of environmental parameters and their influence on stratal architecture and facies distribution. I wish to be able decipher the stratigraphy on margins to read the geologic record of the past and predict future stratigraphy. OBJECTIVES EuroSTRATAFORM is an opportunity to extend stratigraphic model applicability to new margins and to expand the capabilities of our products. The Rhône and Adriatic margins are similar to the earlier field areas in that they are mid-latitude clastic margins, but the stratigraphy is highly affected by the 3D geometry of the basins. The forcing provided by these boundary conditions provide a challenge, but are also necessary for modeling realistic systems. My aim is to quantitatively determine the system response of margins to different forcing functions sufficiently to be able to both predict stratigraphy and invert observed sequence architecture for geologic history. APPROACH I have used numerical models as a tool to provide insight into the formation and preservation of stratigraphic sequences at continental margins. To study these margins I will apply a multi-pronged approach. Together with Italian and French colleagues, I have been modifying and apply our existing 2D stratigraphic models to serial sections of the two EuroSTRATAFORM margins. This will test the portability of the models. It will also aid in evaluating the relative along-and across-strike transport and tectonics, and their influences on sequence architecture. John Swenson, with assistance from Chris Paola, Juan Fedele, I and others are jointly developing a 3-D sequence stratigraphic model. Together, we will extend our time-averaged, moving-boundary model for continental-margin sedimentation with its coupling of multiple transport regimes from 2-D to 3-D. The advantage of this modeling approach is that it allows for a systematic exploration of the margin's response to variations in sea level, sediment supply, tectonic subsidence, and wave climate over longer timescales. I am providing flexural component and parameterizations for the field areas. I will also make use of 3D flexural modeling and backstripping being done for a separate project on the Gulf of Lion to recover 1
