Is there evidence for geostrophic currents preserved in the sedimentary record of inner- to middle-shelf deposits?; discussion and reply

Autor: J. W. Snedden, D. J. P. Swift, D. A. Leckie, L. F. Krystinik

Publikováno v: Journal of Sedimentary Research. 61:148-154

Unidirectional, oscillatory and combined-flow paleocurrent data from many ancient wave-dominated coastlines indicate that sediment transport was directed offshore at angles of 70 to 90° from the inferred local paleoshoreline. Solemarks and parting l

An actualistic perspective into Archean worlds - (cyano-)bacterially induced sedimentary structures in the siliciclastic Nhlazatse Section, 2.9 Ga Pongola Supergroup, South Africa

Publikováno v: Geobiology. 6(1)

Extensive microbial mats colonize sandy tidal flats that form along the coasts of today's Earth. The microbenthos (mainly cyanobacteria) respond to the prevailing physical sediment dynamics by biostabilization, baffling and trapping, as well as bindi

Preliminary results of coincident current meter and sediment transport observations for wintertime conditions on the Long Island Inner Shelf

Publikováno v: Geophysical Research Letters. 3:97-100

We have observed late fall and winter bedload sediment transport and the overlying current field in ridge and swale topography on the inner continental shelf south of Long Island, and can report movement of bed material at a water depth of 20 m to a

Time and space distribution of megaripples and associated bedforms, Middle Atlantic Bight, North American Atlantic Shelf

Autor: D. J. P. Swift, G. L. Freeland, Robert A. Young

Publikováno v: Sedimentology. 26:389-406

Three genetically distinct size classes of lower regime transverse bedforms have long been known from laboratory studies, and from studies of the intertidal zone; ripples, megaripples, and sand waves. These features are also present on the subtidal s

Preliminary studies of intertidal sand bodies in the Minas Basin, Bay of Fundy, Nova Scotia

Autor: D. J. P. Swift, R. M. McMullen

Publikováno v: Canadian Journal of Earth Sciences. 5:175-183

Sand winnowed from bay-floor deposits and eroded from sea cliffs in the Minas Basin has been swept into a series of intertidal sand-body complexes. Continuous seismic profiles show that these are plano-convex or tabular sand masses up to 30 m thick a
