ABSTRACT Cyanobacterial films and mats syndepositonally influence erosion, deposition, deformation of sediments. The biomass levels surface morphologies, microbial stabilize depositional surfaces shelter the sediment against erosion or degassing. Growing dredge grains from their substrate upwards, whereas cyanobacterial filaments that are oriented perpendicular to mat reach into supernatant water baffle, trap, bind suspended particles. These similar biotic-physical interactions reflected in...

A catalogue of microbial structural signatures is presented, based upon the coupling fundamental biogeochemical–microbial processes and local morphogenetic determinants. It summarizes a collection sedimentary structures obtained from two modern siliciclastic peritidal environments in different climatic zones (temperate humid: Mellum Island, southern North Sea; subtropical arid: coast Tunisia). Textural geometries reveal high diversity, but their determinants are primarily six major...

Land management in coastal areas has to cope with impacts of climate change and sea level rise. In Germany, landscape plans assess organize the spatial allocation land use as an environmental contribution general planning. Collaborative planning processes are important develop sustainable ecosystem-based strategies make landscapes proof. However, there is little experience collaborative practical probably other countries well. This paper conducts empirical case study low-lying northwest...

Marine spatial planning is emerging as an integrated, resource management-led approach to governing the use of seas. Recent initiatives include those some north European countries, including Germany, which has now completed a plan for its federal offshore territory. In this article, analysis presented pioneering and consultation process behind production, with particular emphasis on treatment different sectoral interests around was structured. This revealed attempts coordinate not only...

Abstract Coping with the growing impacts of flooding in EU countries, a paradigm shift flood management can be observed, moving from safety‐based towards risk‐based approaches and holistic perspectives. Flood resilience is common denominator most approaches. In this article, we present ‘Flood Resilience Rose’ (FRR), tool to promote harmonised action European regions beyond. The FRR result two‐step process. First, based on scientific concepts as well analysis relevant policy documents,...

The interaction of stakeholders is regarded key in modern environmental and spatial planning. Marine/maritime planning (MSP) an emerging marine policy domain, which great interest worldwide. MSP practices are characterized by diverse approaches a lack transnational cooperation. Actors with various backgrounds have to identify mismatches synergies jointly aim towards coherent coordinated practices. ‘Living Q’ communication method make actors aware systematically about their viewpoints...

Bioenergy is a building block of the ongoing transformation toward renewables-based energy systems. supply chains are regionally embedded and need to be seen in place-based context with specific characteristics constraints. Using German case study, potential bioenergy past future analyzed discussed this paper. The analysis integrates socio-ecological data applies sustainability criteria multi-criteria decision (MCDA) using Preference Ranking Organization Method for Enriched Evaluation...

Abstract Black reduced sediment surfaces (Black Spots) in sandy intertidal flats of the German Wadden Sea (southern North Sea) are characterised by elevated sulphide concentrations (up to 20 mM) and low redox potentials. It is assumed that appearance Spots linked levels organic matter content within sediments. In order establish effect high substrate on heterotrophic microbial communities Spot sediments, bacterial abundances potential C-source utilisation patterns were compared natural...

Integrated coastal management (ICM) has been considered worldwide to be a suitable approach realizing comprehensive schemes protect or develop regions. A complex regulatory system stretching from international local levels provides framework for ICM practices. This raises the question whether and what extent practices have supported by legal policy frameworks at national in different settings both developed developing countries. paper examines four case studies Germany, Costa Rica, Mexico...

A novel method for the quantitative characterization of density distributions elements in sedimentary geosystems is presented. This general technique based on multifractal analysis image‐processed elemental maps obtained by scanning electron microscopy combined with energy dispersive X ray spectrometry. Applications to microdistributions Si, Fe, and Al recent bioactive siliciclastic marine sediments are reported. Inhomogeneous scaling behavior these observed all cases. Two main conclusions...

Civic energy has developed to become a key driver of transition the system locally-sourced, renewables-based economy whereby individual civic initiatives exhibit highly diverse forms and agency characteristics. Together they challenge incumbent corporate, fossil-based its underlying techno-economic paradigm. For meet this challenge, we argue that potential for process optimization needs be systematically assessed propose design as continuous improvement in order address need...
