The Quaternary evolution of the mid-Norwegian continental margin
… Quaternary Naust Formation on the mid-Norwegian continental shelf and slope, both at a high level of detail and over a huge areal extent of over 150,000 km2. First, the analysis of broad-scale margin architecture demonstrates the gradual development and increase in number of cross-shelf troughs …

Geotechnical characterization of sediments from Hydrate Ridge, Cascadia Continental Margin
… from ODP Site 1244, Hydrate Ridge, Cascadia Continental Margin with the goal of understanding the stress history, consolidation behavior and strength characteristics of the soil. A series of Constant Rate of Strain Consolidation (CRSC) and Ko- Consolidated Undrained triaxial (CKoU) tests were …

Tectonics of the West Iberia continental margin from seismic reflection data
Continental rifting is a fundamental component of the plate tectonic cycle. The West Iberia passive margin is a classic example of a nonvolcanic rifted margin. The West Iberia margin contains an enigmatic north-south ridge of serpentinized peridotite located within the ocean-continent transition. …

Seismic stratigraphy and tectonic evolution of a transform continental margin, offshore Sierra Leone
… the northernmost end of the equatorial Atlantic margin in the South Atlantic; it is bound to the South by the Gulf of Guinea Petroleum province. The Sierra Leone margin has not had the exploration attention like most basins in the equatorial Atlantic, such lack of attention may be explained by …

Sedimentation on the continental margin off the Orange River and the Namib Desert
… geology and the superficial sediments of the continental margin off the Orange River and the Namib Desert. The study area is bounded by latitudes 25° and 3o0 s. The Orange shelf is up to 100 km wide and 200 m deep, and the Walvis shelf off Lllderitz is up to 80 km wide and 400 m deep, the …

Sediments on the continental margin off South West Africa between latitudes 17⁰ and 25⁰ S
… the north-central part of the South West African continental margin. It covers approximately 57 000 n.miles² , and extends from 2 n.miles offshore to a depth of about 1 500 m. Four cruises of the R.V. THOMAS B. DAVIE were undertaken over a two year period (May, 1972 to May, 1974) to collect 555 …

Sedimentation on a mixed siliciclastic/carbonate continental margin over decadal to millennial timescales: Gulf of Papua
Sediments from the Gulf of Papua were examined to estimate particle flux and sediment mass accumulation rates on multiple timescales. Patterns of sediment mass accumulation and inventory-derived 210Pb fluxes display regional variations, decreasing seaward, and along isobaths seaward from the …
