Effect of hydro-climate variation on biofilm dynamics and its impact in intertidal environments (2022)
Journal Article
Bastianon, E., Hope, J. A., Dorrell, R. M., & Parsons, D. R. (2022). Effect of hydro-climate variation on biofilm dynamics and its impact in intertidal environments. Earth surface dynamics European Geosciences Union, 10(6), 1115-1140. https://doi.org/10.5194/esurf-10-1115-2022

Shallow tidal environments are very productive ecosystems but are sensitive to environmental changes and sea level rise. Bio-morphodynamic control of these environments is therefore a crucial consideration; however, the effect of small-scale biologic...

Interactions between sediment microbial ecology and physical dynamics drive heterogeneity in contextually similar depositional systems (2020)
Journal Article
Hope, J. A., Malarkey, J., Baas, J. H., Peakall, J., Parsons, D. R., Manning, A. J., Bass, S. J., Lichtman, I. D., Thorne, P. D., Ye, L., & Paterson, D. M. (2020). Interactions between sediment microbial ecology and physical dynamics drive heterogeneity in contextually similar depositional systems. Limnology and Oceanography, 65(10), 2403-2419. https://doi.org/10.1002/lno.11461

This study focuses on the interactions between sediment stability and biological and physical variables that influence the erodibility across different habitats. Sampling at short-term temporal scales illustrated the persistence of the microphytobent...

Integrating field and laboratory approaches for ripple development in mixed sand–clay–EPS (2019)
Journal Article
Baas, J. H., Baker, M. L., Malarkey, J., Bass, S. J., Manning, A. J., Hope, J. A., Peakall, J., Lichtman, I. D., Ye, L., Davies, A. G., Parsons, D. R., Paterson, D. M., & Thorne, P. D. (2019). Integrating field and laboratory approaches for ripple development in mixed sand–clay–EPS. Sedimentology, 66(7), 2749-2768. https://doi.org/10.1111/sed.12611

The shape and size of sedimentary bedforms play a key role in the reconstruction of sedimentary processes in modern and ancient environments. Recent laboratory experiments have shown that bedforms in mixed sand–clay develop at a slower rate and ofte...

Bedform migration in a mixed sand and cohesive clay intertidal environment and implications for bed material transport predictions (2018)
Journal Article
Lichtman, I. D., Baas, J. H., Amoudry, L. O., Thorne, P. D., Malarkey, J., Hope, J. A., Peakall, J., Paterson, D. M., Bass, S. J., Cooke, R. D., Manning, A. J., Davies, A. G., Parsons, D. R., & Ye, L. (2018). Bedform migration in a mixed sand and cohesive clay intertidal environment and implications for bed material transport predictions. Geomorphology, 315, 17-32. https://doi.org/10.1016/j.geomorph.2018.04.016

Many coastal and estuarine environments are dominated by mixtures of non-cohesive sand and cohesive mud. The migration rate of bedforms, such as ripples and dunes, in these environments is important in determining bed material transport rates to info...

The role of biophysical cohesion on subaqueous bed form size: COHESION IN SUBAQUEOUS BED FORMS (2016)
Journal Article
Parsons, D. R., Schindler, R. J., Hope, J. A., Malarkey, J., Baas, J. H., Peakall, J., Manning, A. J., Ye, L., Simmons, S., Paterson, D. M., Aspden, R. J., Bass, S. J., Davies, A. G., Lichtman, I.

Geophysical research letters, 43(4), 1566-1573. https://doi.org/10.1002/2016gl067667

Biologically active, fine-grained sediment forms abundant sedimentary deposits on Earth's surface, and mixed mud-sand dominates many coasts, deltas, and estuaries. Our predictions of sediment transport and bed roughness in these environments presentl...

The pervasive role of biological cohesion in bedform development (2015)
Journal Article
Malarkey, J., Baas, J. H., Hope, J. A., Aspden, R. J., Parsons, D. R., Peakall, J., Paterson, D. M., Schindler, R. J., Ye, L., Lichtman, I. D., Bass, S. J., Davies, A. G., Manning, A. J., & Thorne, P. D. (2015). The pervasive role of biological cohesion in bedform development. Nature communications, 6(1), Article ARTN 6257. https://doi.org/10.1038/ncomms7257

Sediment fluxes in aquatic environments are crucially dependent on bedform dynamics. However, sediment-flux predictions rely almost completely on clean-sand studies, despite most environments being composed of mixtures of non-cohesive sands, physical...
