Benthic organisms can significantly alter the physical properties of marine sediments, but it has hitherto been difficult to assess and quantify the effects of bioturbation. In situ geophysical techniques offer new methods for measuring these effects: measurement of acoustic shear-wave velocity and electrical resistivity allows nondestructive assessment of the properties of the grain framework and pore-fluid matrix, respectively, of the seabed sediment. The influence of burrowing invertebrates… Expand
The effects of bioturbation on sediment transport on an intertidal mudflat
Abstract Laboratory flume studies were conducted to determine the relative importance of various biological and physical factors controlling sediment erosion threshold and transport rate on anExpand
Sediment dynamics modulated by burrowing crab activities in contrasting SW Atlantic intertidal habitats
Abstract Biogenic bottom features, animal burrows and biological activities interact with the hydrodynamics of the sediment–water interface to produce altered patterns of sediment erosion, transportExpand

Irrigation patterns in permeable sediments induced by burrow ventilation: a case study of Arenicola marina
In sandy sediments, a strong connection exists between the physics of flow and the ecol- ogy of burrow-ventilating macrofauna. We developed a general modelling procedure that quantifies this linkExpand
The effects of chemical pollution on the bioturbation potential of estuarine intertidal mudflats
Abstract Bioturbation by benthic infauna has important implications for the fate of contaminants as well as for changes to the sediment structure, chemistry and transport characteristics. There is anExpand
Benthic community structure and sediment processes on an intertidal flat: results from the ECOFLAT project
Interactions between physical and biological processes in intertidal sediments have been the focus of studies in the framework of the ECOFLAT project. Process studies were focused on the Molenplaat,Expand
Microscale biogeotechnical differences in intertidal sedimentary ecosystems
Abstract Intertidal sediments are inhabited by organisms that can modify the geotechnical and sedimentological properties of the sediment. We have analysed small scale differences in these propertiesExpand
Sediment erodability in sediment transport modelling: Can we account for biota effects?
Abstract Sediment erosion results from hydrodynamic forcing, represented by the bottom shear stress (BSS), and from the erodability of the sediment, defined by the critical erosion shear stress andExpand
Accurate quantification of the influence of benthic macro- and meio-fauna on the geometric properties of estuarine muds by micro computer tomography
There is potential for further development of this software to allow more detailed analysis of burrow structures and surface features including parameters such as burrow length, shape and sediment surface roughness. Expand


The Effects of Marine Benthos on Physical Properties of Sediments
The effects of benthic organisms on the physical properties of granular substrata are well documented. The range of effects has been presented in H. B. Moore (1931, 1939), Schwartz (1932), DapplesExpand
Modification of sediment permeability and shear strength by two burrowing invertebrates
The correlations between shear strength and permeability and between permeable and water content were affected differently by the two species and there were few partial correlations between the variables. Expand
Geophysical properties of surficial sediments : textural and biological controls
The structural properties of surficial sedimentary deposits strongly influence exchange processes across the benthic boundary layer, and hence are important factors controlling sedimentation andExpand

Heterogeneous grain size distribution in tidal flat sediment caused by bioturbation activity of Arenicola marina (polychaeta)
A mechanism which causes the chance of a particle to stick to the mucus covered papillae on the lugworm's proboscis and to be swallowed depends on its surface area; smaller particles have a greater chance than large ones. Expand

Sediment stability around animal tubes: The roles of hydrodynamic processes and biotic activity1
Critical entrainment velocities for natural cohesive sediments in these treatments were 46% lower in the cores with high densities of macrofauna than in those with low densities, suggesting biotically mediated sedimentological changes around D. cuprea tubes, rather than alterations of near-bed flow by the tubes, are responsible for lowering erosion thresholds in this system.
