“…It is geologically speaking a young system formed about 7000 years before present and basically shaped by North Sea and Atlantic hydrodynamic forces accumulating sediments and initiating a series of barrier islands behind which reduced hydrodynamics enabled the deposition of vast sand e and mudflats developing into salt e and freshwater marshes. Most of the sediment that formed the Wadden Sea and adjacent coastal plains is derived from the North Sea and was deposited in the North Sea region during the last ice ages (Beets and van der Spek, 2000;Hoselmann and Streif, 2004).…”

a b s t r a c tThe scale of human pressures on marine ecosystems gradually increased from local to global effects during the last centuries. Global warming, sea level rise and trans-oceanic spread of alien species are now or will be major drivers of ecological change in the Wadden Sea. Eutrophication may rank as a superregional effect as the organic matter turnover in the Wadden Sea is driven by import from the North Sea. These effects will not necessarily be uniform across the entire Wadden Sea. A major challenge will be to understand the interactions between global factors with local conditions, both changed by human interference. A conceptual understanding of factors leading to regional differences within the Wadden Sea is only slowly evolving. Based on our understanding of the eutrophication process and a regional comparison of the eutrophication status of the Wadden Sea we propose that wider tidal basins (with a large distance between barrier islands and the mainland) generally have a lower eutrophication status than narrower tidal basins (with a short distance between barrier islands and mainland). This may be explained by a "dilution" of the imported organic matter in wider tidal basins. The interactions between global and super-regional effects on local ecological developments in the Wadden Sea will be complex and pose a major challenge to science, Wadden Sea management and the assessment of ecosystem health as required by EU legislation. The implications of integrating a North Sea view into Wadden Sea management are discussed and we conclude that the river basin approach of the EU Water Framework Directive is not appropriate for the Wadden Sea.

“…However, Ludwig & Figge (1979) found only A group assemblages (cf. section 4.1) on the shoreface and suggested that ongoing reworking of glacial deposits (Hoselmann & Streif, 2004) is reinforcing the existing A group and diluting any H group influxes brought in by the prevailing westerly longshore drift. …”

“…This material was later mixed with illite-and chlorite-rich sediments from the north but nonetheless remained rich in smectite. Using mass-balance calculations, Hoselmann & Streif (2004) calculated that 90% of the sediment volume along the Lower Saxony Irion & Zöllmer, 1999). coast originates from submarine erosion of the seafloor whereas only 10% originates from the Ems, Weser and Elbe rivers. Müller & Forstner (1975) and Irion et al (1987) even assumed transport of fine-grained uncontaminated sediments from the North Sea as far as Hamburg in the Elbe estuary and a decreasing mixing with the fluvial suspension load to explain the upstream increase in heavy metal contents of the river sediments.…”

Minerals are the building blocks of clastic sediments and play an important role with respect to the physico-chemical properties of the sediment and the lithostratigraphy of sediments. This paper aims to provide an overview of the mineralogy (including solid organic matter) of sediments as well as suspended matter as found in the Netherlands (and some parts of Belgium). The work is based on a review of the scientific literature published over more than 100 years. Cenozoic sediments are addressed together with suspended matter and recent sediments of the surface water systems because they form a geoscientific continuum from material subject to transport via recently settled to aged material. Most attention is paid to heavy minerals, clay minerals, feldspars, Ca carbonates, reactive Fe minerals (oxides, siderite, sulphides, glauconite) and solid organic matter because they represent the dominant minerals and their properties form a main issue in subsurface and water management. When possible and relevant, the amounts, provenance, relationship with grain size distribution, early diagenesis and palaeohydrological evolution are described. Tables with statistical data about the mineral contents and isotopic composition of carbonates and organic matter are presented as overviews. The review on the mineralogy of Dutch fluvial and marine environments is more extensive than that for the other sedimentary environments because the first two have been studied much more intensively than the others and they also form the larger part of the Dutch deposits. The focus is on the natural background mineralogy of Dutch sediments, but this is hard for recent sediments, largely because the massive hydraulic infrastructure present in the Netherlands has probably also affected the mineralogy and geochemistry of sediments deposited in recent centuries. Many findings are summarised, several of which lead to more general insights for the Dutch situation. Ca carbonates in sediments often have several provenances and thus must be considered as mixtures. Dolomite is commonly present in addition to calcite. The importance of biotite as weatherable mica is unclear. Weathering of heavy minerals plays some role but it is unclear in which way it affects the heavy mineral associations. Clays are usually dominated by illite, smectite and their interstratified variant, while kaolinite is usually below 20% and chlorite below 5%. Vermiculite is a minor constituent in fluvial clays and its illitisation presumably happens during early diagenesis in the marine environment. Opaque Fe hydroxides can be present in addition to Fe oxyhydroxide coatings and both will play a role in redox chemistry as reactive Fe minerals. Feldspars in marine sediments must be present but they have not been properly studied. The genesis of rattle stones and carbonate concretions has not been completely elucidated. The fraction of terrigeneous organic matter in estuarine and coastal marine sediments is substantial. The available data and information are spread irregularly over the country and the reviewed information discussed in this paper is derived from relatively small-scale studies dealing with a limited amount of analysed samples. Much information is available from the Scheldt estuaries in the southwestern part of the Netherlands partly due to the severe contamination of the Western Scheldt in recent decades.

“…Resolving the interaction of intertidal sediment accumulation rates and sea-level on various timescales Before this study commenced, it was generally believed that the rate of long-term (millennial timescale) intertidal sedimentation in a subsiding tidal basin followed the rate of relative sea-level rise, leading to the formation of a sediment accumulation wedge in tidal basins (Vos and van Kesteren, 2000;Hoselmann and Streif, 2004). However, little was known about whether such sedimentation can keep pace with the rapid sea-level fl uctuations that may occur on decadal or centurial timescales.…”

Depositional processes in intertidal areas are determined both by changes in sea-level and sediment supply. It is known on a millennial timescale that sedimentation normally keeps pace with sea-level rise in a subsiding tidal basin. However, little is known about whether the sedimentation can keep pace with the rapid sea-level fl uctuations that may occur on decadal or centurial timescales. Here, the sediment accumulation rates on two tidal fl ats in the Lister Dyb tidal basin (Wadden Sea, Denmark) are quantifi ed in time and space in order to understand the interaction between changes in sea-level and sediment supply. Absolute chronologies, obtained using optically stimulated luminescence (OSL) and radiocarbon dating ( 14 C), are presented from seven sediment cores. Forty-seven OSL ages, ranging between 6 ± 1 and 12 600 ± 900 years, were obtained. Six independent 14 C age-estimates, ranging between 3800 ± 100 and 5620 ± 30 cal. BP, support the OSL chronology. The absolute chronology allowed a description of the spatial and temporal variability of intertidal sediment accumulation rates across an aggrading tidal lagoon. On the mudfl at in the western and sheltered part of the lagoon the intertidal sedimentation has followed the rate of relative sea-level rise, at least over the last ~2000 years, whereas the trends in sediment accumulation rates on the sandy tidal fl at in the eastern and exposed part of the lagoon are less clear. Here, there is large variability in sediment accumulation rates and there may be patchy areas of erosion and accumulation. We conclude, however, that sediment accumulation on the two tidal fl ats in Lister Dyb tidal basin generally has kept pace with the rising sea-level. This conclusion seems to apply over the last few centuries and is generally true over the last few millennia. Furthermore, we conclude that sheltered mudfl ats appear to give the best description of how intertidal sedimentation responds to sea-level fl uctuations.
