Glacier-Influenced Sedimentation on High-Latitude Continental Margins

EuroSTRATAFORM: Three-Dimensional, Moving-Boundary, Integrated- Morphodynamic Models of Sedimentation on Continental Margins

Figure 1. Cross-sectional model of continental-margin response to high-amplitude fluctuations in eustatic sea level. The panels represent (A) floodand (B) stormdominated margins. Large panels show stratigraphic architecture resulting from two sea-level cycles superimposed on steady background subsidence. Red circles denote shoreface location. Stratal spacing: ∆t = 0.6. Insets show eustatic sea ...

Quantitative Constraints on the Origin of Stratigraphic Architecture at Passive Continental Margins: Oligocene Sedimentation in New Jersey, U.s.a

The Oligocene of the New Jersey continental margin is divisible into as many as eight sequences and 23 lithofacies associations, documented in a series of seven boreholes across the modern coastal plain. This paper summarizes the sequence architecture of these deposits, interpreted from high-resolution biostratigraphy and Sr-isotope chemostratigraphy, and evaluates the factors that governed pat...

Statistical Characterization of Bathymetry and Stratigraphy on Continental Margins

A "realistic" interpolation or extrapolation of bathymetry, i.e., one that honors both the statistical character and the deterministic constraints of the data, is referred to as a "conditional simulation." The first step in generating a conditional simulation is derivation of a statistical model for bathymetry. We typically employ the anisotropic von Kármán model (Goff and Jordan, 1988), which ...

Global distribution of naturally occurring marine hypoxia on continental margins

Hypoxia in the ocean influences biogeochemical cycling of elements, the distribution of marine species and the economic well being of many coastal countries. Previous delineations of hypoxic environments focus on those in enclosed seas where hypoxia may be exacerbated by anthropogenically induced eutrophication. Permanently hypoxic water masses in the open ocean, referred to as oxygen minimum z...
