“…Sedimentation in both the Rockall and Faroe-Shetland basins continued in several pulses throughout the Eocene, as reflected by the deposition of a series of progradational shelf-margin to basinal sequences derived from the Hebrides and West Shetland shelves, the Faroe Shelf, and the Rockall Plateau (Andersen et al, 2002;Praeg et al, 2005;McInroy et al, 2006; Fig. 2A).…”

“…The uplift and deformation of passive continental margins is a matter of wide debate and interest, because passive margins are generally expected to experience only decaying thermal subsidence during the post-rift stage of their evolution (Praeg et al, 2005). The Cenozoic uplift and deformation of the British Isles and the adjacent Atlantic Margin is an example that has been well studied both onshore and offshore using data largely acquired in the search for hydrocarbons.…”

“…Although a tectonic uplift component has been proposed by many authors (Japsen & Chalmers, 2000;Overeem et al, 2001;Dahlgren et al, 2005;Stoker et al, 2005), Golzdowski et al (2012) suggest that the Plio-Pleistocene erosion history of Scandinavia (and therefore of offshore sedimentation) is solely a result of the colder climate with more abundant periglacial process-dominated denudation, increased seasonality, glaciation and ice sheet overriding of watersheds. Some authors have considered the increased sediment supply could result from a combination of the two processes (e.g.…”

Filling the North Sea Basin: Cenozoic sediment sources and river styles

ABSTRACT. The history of the infilling of the North Sea is outlined, with particular focus on sediment sources and river inputs. In simple terms (for the detail is complex), these sources changed from domination by northwesterly sources from the Shetland area (Paleocene to Eocene), to a geographically more uniform basin-centred pattern, and then northerly input following Fennoscandian uplift (Oligocene and Neogene). Baltic inputs followed via an 'Eridanos (Baltic) River' (Miocene), with cold-climate coarser sediment inputs, and lacustrine episodes resulting from ice damming (Pleistocene). River styles in each of these phases are discussed, with the Cenozoic at first being dominated by low energy fluvial deposition (channel sands, chemically weathered clays, and organic sedimentation) in fluctuating climates. Cold climates in the latest Neogene and Quaternary are seen as major determinant of a change in fluvial style, though these are also associated with tectonic effects, as in Scandinavia. The mediating role of vegetation, relating also to temperature and precipitation, is also likely to have been significant. Narrow valley incision followed the Middle Pleistocene Transition, as well as an increasing importance of Rhine-Meuse sources that had begun earlier.

“…On the central and western parts of the Rockall Trough, adjacent to the Rockall Bank, the multibeam bathymetry data provide a detailed view of the Feni Drift which is one of the largest contourite drifts in the NE Atlantic (Stoker et al, 2005;Unnithan et al, 2001). …”

Multibeam echosounder data collected by the Irish National Seabed Survey (INSS) between 2000 and 2001 in the Rockall Trough have been used by many projects to analyze the geomorphology and the sedimentary processes of the margins of the Trough. However, due to the low spatial resolution of 150-250 m and the amount of artefacts still embedded in the publicly available data, many geomorphological features have been overlooked. This paper shows that the same multibeam dataset can provide more detailed information on seabed processes when the latest hydrographic and backscatter post-processing techniques are used to reduce data artefacts and improve data quality and spatial resolution.The resulting map, presented here at a scale of 1:450,000, is based on a semi-automatic and manual interpretation of geomorphological features highlighted using a new and improved 30 m bathymetric grid and a multibeam backscatter mosaic obtained using the GEOCODER post-processing algorithm.Overall, the map shows a complex sedimentological scenario where the Rockall Bank Mass Flow failure, the Donegal-Barra trough-mouth fan, along slope structures such as the Feni Contourite Drift and the Porcupine moat dominate the Rockall Trough flanks and basin floor. Smaller features such as canyon and gully systems, escarpments, coral mounds, volcanic mounds and iceberg scours have also been mapped in detail. In addition, the interpretation of the backscatter mosaic allows for the first time the identification of depositional lobes generated by downslope mass transport and canyon drainage systems, particularly where these features completely lose their bathymetric expression.
