Geosyst., 12, Q03004, doi:10.1029/2010GC003347. Introduction: This auxiliary material includes data sets used in this study including a high-resolution seismic reflection profile. We distribute these data sets for additional analyses that could be taken place by readers. 1. 2010gc003347-txts01.pdf Text S1. The results from our seismic interpretation with a table for the calculated radii. The x-value is horizontal distance indicated by CDP number (1CDP = 25 m for the 4 channel surveys, and 6.25 m for 48 channel surveys, Table 2 and Data Set S1) and y-value is two-way travel time in milliseconds. The y-values with two-way travel time (ms) were converted into depth (m) using the relationship between travel-time and depth suggested by Bloomer et al. (1995) and Busch et al. (2006). We selected representative basins or regions with a combination of high and low topography from each study site and fit a best-fit 2-D polynomial curve for each interpreted horizon. 2. 2010gc003347-fs01.pdf Figure S1.
