Journal ArticleDOI
Fluid mud dynamics in the Weser estuary turbidity zone tracked by high-resolution side-scan sonar and parametric sub-bottom profiler
TL;DR: In this paper, the combined use of a side-scan sonar (Sportscan®, Imagenex) and a parametric sub-bottom profiler (SES-2000®, Innomar Technology GmbH) has proved successful for high-resolution fluid mud detection and volumetric quantification in an estuarine environment.
Journal ArticleDOI
Hydrodynamics and sediment dynamics in the German Bight. A focus on observations and numerical modelling in the East Frisian Wadden Sea
Joanna Staneva,Emil V. Stanev,Jörg-Olaf Wolff,Thomas H. Badewien,Rainer Reuter,Burghard W. Flemming,Alexander Bartholomä,Karsten Bolding +7 more
TL;DR: In this paper, the authors deal with analysis of hydrographic observations and results of numerical simulations, using a suspended matter transport model to describe and validate new and so far unknown patterns of sediment distribution.
Journal ArticleDOI
Suspended sediment transport in the German Wadden Sea—seasonal variations and extreme events
TL;DR: In this paper, the authors investigated the transport of suspended sediment on seasonal, tidal and hourly time scales in the back-barrier system of Spiekeroog Island, which is composed of both cohesive and non-cohesive deposits.
Journal ArticleDOI
The drivers of biogeochemistry in beach ecosystems: A cross-shore transect from the dunes to the low-water line
Melanie Beck,Anja Reckhardt,Julia Amelsberg,Alexander Bartholomä,Hans-Jürgen Brumsack,Heribert Cypionka,Thorsten Dittmar,Bert Engelen,Janek Greskowiak,Helmut Hillebrand,Moritz Holtappels,René Neuholz,Jürgen Köster,Marcel M. M. Kuypers,Gudrun Massmann,Daniela Meier,Jutta Niggemann,Ronja Paffrath,Katharina Pahnke,Sandra Rovo,Maren Striebel,Verona Vandieken,Achim Wehrmann,Oliver Zielinski +23 more
TL;DR: In this paper, spatial variations in subsurface pore water residence times, salinity, organic matter (OM) availability, and redox conditions and their effects on nutrient cycles as well as on microbial community patterns and microphytobenthos growth are assessed.
Journal ArticleDOI
How round is round? A new approach to the topic ‘roundness’by Fourier grain shape analysis
TL;DR: In this paper, the amplitude spectrum of a particle's maximum projection plane is transformed to a Fourier series and the residual amplitudes are normalized and summed, and the resulting values are rescaled.
