Contourite

Mounded contourite-turbidite sequences

Channel-levee sequences (Turbidites)

Foldout PB-2: Seismic sections from western Prydz Bay (Section A-A'). The very thick post-rift section includes thick contourite (drilled) and turbidite (inferred) mounds with mudwaves in places. The upper slope comprises the Prydz Channel Fan and the shelf shows progradation but only limited topset thickness. The base of Prydz Channel Fan is

Reflector A of Mizukoshi et al. (1986) and PP-12 of O'Brien et al. (2004). Location shown in Fig. PB-19.

Foldout WS-1: Seismic line NARE-8508 along the front of the Crary Trough Mouth Fan, showing fan architecture (modified from Kuvaas and Kristoffersen, 1991). Profile location is in Fig. WS-1.

Foldout AP-1: Seismic line BAS878-19 across the Antarctic Peninsula Pacific margin, showing the shelf basin, prograding wedge and continental rise sediments between the continental slope and DSDP Site 325. A buried, early Miocene sediment drift is observed beneath the central rise (Hernandez-Molina et al., 2004, 2006b), but this line lies between two of the large drifts that have developed since the start of the middle Miocene (Rebesco et al., 1996, 1997, 2002). Oceanic basement ages are from Larter et al. (1997). Vertical exaggeration at the seafloor is 23:1. Inset in upper right shows an interpretation of major features. Inset in lower left shows line location.
