Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

High-resolution seismic investigations have been carried out jointly by the Alfred-Wegener-Institut für Polar- und Meeresforschung (Bremerhaven) and the Renard Centre of Marine Geology (State University of Ghent, Belgium) in the Weddell Sea basin during the austral summer season 1986-1987. A total of 2869 km of seismic profiles, most of them with 24-channel data acquisition, have been shot in surveys which addressed four distinct marine geological domains : (a) oblique prograding sediment wedges in the southern Weddell Sea, off Filchner Ice Shelf and Halley Bay ; (b) a thick sedimentary sequence which possibly represents the distal part of a very extensive sedimentary fan, overlying the axial zone of a failed rift/drift basin ; ( c ) the continental margin off Riiser-Larsen Ice Shelf and Cape Norvegia, close to the Explora Escarpment and the Wegener Canyon, where seismic support was provided to the ongoing drilling activities in the framework of Leg 113 of the Ocean Drilling Program ; (d) the active plate boundary between Bransfield Strait and the South Orkneys, where a back-arc extensional basin is found in close association with an oblique subduction zone.
