International Ocean Discovery Program (IODP) Site U1461 is 100 km northwest of Barrow Island in the Northern Carnarvon Basin, ~150 m from the West Tryal Rocks-2 industry well (Figure F1). Site U1461 is on the shelf edge of an outer ramp (James et al., 2004). The seabed in the region is poorly sorted carbonate-rich (>90%) sediment made up of bioclastic gravel, sand, and mud (Jones, 1973; James et al., 2004). Coring at Site U1461 targeted a 1 km thick outer shelf to upper slope carbonate wedge that onlaps (because of basin-wide subsidence) a regional top Miocene surface (Figures F2, F3).

Site U1462
International Ocean Discovery Program (IODP) Site U1462 is 50 km north of the Montobello Islands in the Northern Carnarvon Basin, ~150 m from the Fisher-1 industry well (Figures F1, F2). Site U1462 is on the outer edge (87 m water depth) of a middle ramp (James et al., 2004). The seabed in the region is carbonate-rich (>90%) gravel and sand with minor mud (Jones, 1973; James et al., 2004). Coring at Site U1462 targeted a sequence of shelfal to shelf-edge carbonates that overlie a Miocene sand unit (the Bare Formation) (Figure F3).

International Ocean Discovery Program (IODP) Site U1463 is ~150 m from the Picard-1 industry well (141 m water depth) on a flat outer ramp region (James et al., 2004). The site is 100 km southwest of IODP Site U1464 (Figures F1, F2). The seabed in the region is poorly sorted carbonate-rich (>90%) sediment made up of bioclastic gravel, sand, and mud (Jones, 1973; James et al., 2004). The wireline gamma ray log data from the Picard-1 Well reveals high variability and an upward reduction that is interpreted to be related to subsidence, glacioeustatic fluctuations, and climate variability from the Pliocene to recent.more » « less

At 270 m water depth, International Ocean Discovery Program (IODP) Site U1464 is currently in an outer ramp setting (James et al., 2004), ~50 km southeast of the Rowley Shoals (Figures F1, F2). The seabed in the vicinity of the site is poorly sorted, carbonate-rich (>90%) sediment made up of bioclastic gravel, sand, and mud (Jones, 1973; James et al., 2004). Site U1464 is 5 km updip from a drowned “fossil” shoal described by Jones (1973) and Ryan et al. (2009) and is connected to the site by parallel laterally persistent reflectors on seismic Profile JN87-07 (Figure F3). Therefore, improved ages for these reflectors may allow us to date the initiation and demise of this reef/shoal.more » « less

In this study, a simplified shallow three-dimensional shear wave velocity (Vs) model is presented for the Mexico City Basin. To this end, previous studies were carefully reviewed to assemble a database of Vs and site period measurements for the region. The new site period measurements obtained at the western edge of the Basin were compared to the existing 2004 Complementary Technical Standards of Mexico site period nominal map, (NTC, 2004) the Lermo et al. (2020) site period map, and Design Seismic Actions System (SASID), 2020 site period predictions. Each site period prediction method was shown to have differences with respect to the new measurements along the western edge of the Basin. However, there was no bias for the prediction methods with the Lermo et al. (2020) and SASID predictions, demonstrating less error between the measured values than the NTC (2004) predictions. To develop the three-dimensional Vs model, the shallow (top 60 m) subsurface was divided into five generalized soil layers. The site period was used as the only input for the three-dimensional Vs model to simplify and maximize the model’s applicability. The performance of the model was assessed by comparing the measured and predicted Vs profiles. Overall, the three-dimensional Vs model developed in this study is a valuable tool that can be used along with geophysical estimates of deeper structure for ground motion modeling and preliminary site response studies along with other benefits to the seismic resiliency of the region.more » « less

International Ocean Discovery Program (IODP) Site U1460 lies in the northern part of the Perth Basin, about 18 nmi north of IODP Site U1459 and ~150 m from the Morangie-1 industry well on the Carnarvon ramp (James et al., 1999; Collins et al., 2014). Site U1460 is north of the Houtman Abrolhos main reef complex, which contains the most southerly tropical reefs in the Indian Ocean (Figures F1, F2, F3).more » « less
