Use of Stochastic Modeling of Stratigraphic Relationships in High Resolution Seismic Reflection Data for Prediction of the Distribution of Acoustic and Geotechnical Property Variability in Near Surface Sediments on the East China Sea Continental Margin
Abstract
During cruises in May and June of 1999, 7991 km of single channel high resolution seismic data and 5278 km of chirp sub-bottom and side-scan sonar data were collected from the continental margin of the East China Sea (ECS) and Yellow Sea. When these data are pooled with data collected in this region during cruises in 1993 and 1996 the total data available for analyses is 15,408 km of seismic profiles and 13,295 km of chirp sub-bottom and side-scan sonar data along with 51 gravity cores. Copies of these data were provided to the Naval Oceanographic Office at Bay St. Louis, Mississippi. These data were processed to minimize noise and subjected to seismic stratigraphic analyses. Correlation of the data with published drill core descriptions indicate that the seismic profiles image stratigraphy that extends back to at least 200,000 years before present. The results of these analyses revealed that the stratigraphy of the margin was strongly impacted by glacially driven sea level fluctuations that produced regional unconformities that can be used to subdivide the stratigraphy into Lowstand (LST). Transgressive (TST) and (Highstand) systems tracts.
