“…Confined by a meso-tidal barrier island chain with intermittent estuaries of major river systems, the wide siliciclastic back barrier tidal flats host a rather resilient ecosystem in the midst of a densely populated and highly industrialized region (Hertweck, 1994;Ducrotoy and Elliott, 1997;Kock, 1998;Grimm et al, 1999).…”

Abstract. The redox succession in shallow marine sediments generally exhibits a predictable pattern. Pore water profiles from a back barrier tidal flat in the German Wadden Sea depart from the expected redox zoning. Instead, a sulfate minimum zone associated with a sulfate-methane-sulfate double interface and a distinct ammonium peak at 1.5 m below sea floor (mbsf) is displayed. Such evidence for significant degradation of organic matter (OM) in subsurface layers is challenging our understanding of tidal flat biogeochemistry as little is known about processes that relocate reactive OM into layers far distant from the sediment-water interface. The objectives of our model study were to identify possible mechanisms for the rapid transport of organic matter to subsurface layers that cause the reversed redox succession and to constrain several important biogeochemical control parameters. We compared two scenarios for OM transfer: rapid sedimentation and burial of OM as well as lateral advection of suspended POM. Using a diagenetic model, uncertain process parameters, in particular those connected to OM degradation and (vertical or lateral) transport, are systematically calibrated using field data.We found that both scenarios, advection and sedimentation, had solutions consistent with the observed pore water profiles. For this specific site, however, advective transport of particulate material had to be rejected since the reconstructed boundary conditions were rather improbable. In the alternative deposition set-up, model simulations suggested the deposition of the source OM about 60 yrs before cores Correspondence to: J. M. Holstein (j.holstein@icbm.de) were taken. A mean sedimentation rate of approximately 2 cmyr −1 indicates substantial changes in near coast tidal flat morphology, since sea level rise is at a much lower pace. High sedimentation rates most probably reflect the progradation of flats within the study area. These or similar morphodynamic features also occur in other coastal areas so that inverted redox succession by horizontal or vertical transport may be more common than previously thought. Consequently, regional values for OM remineralization rates may be higher than predicted from surface biogeochemistry.

“…These needs demand engagement and collaboration between sectors and across borders (Ducrotoy & Elliott, 1997;Elliott et al, 1999;Read et al, 2001;Borja, 2005;Apitz et al, 2007). For instance, in fisheries management, most people agree that there are weaknesses in 15 ICES stock assessments that could be solved with more or better data (Apitz et al, 2006), and that the fleet of fishing vessels at sea presents an opportunity to collect additional data (Mangi et al, 2015;2016;Graham et al, 2011).…”

This study was undertaken to address the increasing need for a strategic approach to industryscience data collections in the face of reducing resources and growing need for evidence in fisheries management. The aim was to evaluate progress in the development of plans and procedures that can be employed to collect, record and use fishing industry knowledge and data in the evidence-base for managing fisheries. This was achieved by reviewing industryled data initiatives already undertaken or ongoing within the United Kingdom to document how these projects have/are incorporating fishing industry data into the process of management decision making; canvassing stakeholder opinion on data gaps and whether these could be filled by data gathered by commercial fishing vessels; establishing what issues might prevent or stimulate commercial fishing vessels in collecting data when they have the opportunity; and describing guidance on a step-by-step process for gathering scientific information such that fishers are empowered to collect the right data, at the right times and in the right format for their fishery. Given recent advances in the collection, interpretation and application of fishery-dependent data, we compare progress made in the UK to other areas of the world. We conclude that there is considerable evidence of a paradigm shift from the conventional practice of scientists asking fishers to provide data for scientific analyses towards full engagement of key stakeholders in data collection.

“…In 1990, during an interministerial conference in The Hague, ministers from various countries decided that countries should develop a methodology for the settlement of ecological quality objectives (see Ducrotoy and Elliott 1997). This can be seen as a major starting point and background for the development of integrated monitoring systems to follow marine ecological quality.…”

Making ecosystem-based management operational: integrated monitoring in Norway

Ecosystem-based management presupposes that the state and development trends of an ecosystem -or of ecological quality -can be measured and followed. Currently, in many coastal countries there exists a variety of monitoring practices that are concerned with single issues only, and are not an integrated part of a larger framework. With the trend towards more comprehensive forms of ecosystem-based management, there is a desire to develop more integrated monitoring frameworks. This paper follows the development of such a framework for the Barents Sea-Lofoten area in Norway, which to a large extent builds upon existing practices, but also suggests additional monitoring programs. It describes how the construction of governance instrumentation for ecosystem-based management takes place. In doing so, it focuses on pollution monitoring. The paper sheds light on the ways in which the ecosystem is made readable and measurable. In addition, it offers insight into the scientific and institutional challenges in the practices towards making ecosystem-based management instrumental and operational.
