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...

We document directly for the first time how major river floods connect to the deep-sea, by analysing the longest runout sediment flows (of any type) yet measured in action. These seafloor turbidity currents originated from the Congo River-mouth, with... Read More about Longest sediment flows yet measured show how major rivers connect efficiently to deep sea.

Agricultural Pea Waste as a Low-Cost Pollutant Biosorbent for Methylene Blue Removal: Adsorption Kinetics, Isotherm And Thermodynamic Studies (2022)
Journal Article

Biosorbents are an alternative pollutant adsorbent, usually sourced from waste biomass and requiring little to no treatment. This makes them cheaper than conventional adsorbents. In this paper, green pea (Pisum sativum) haulm was used as a biosorbent...

First source-to-sink monitoring shows dense head controls sediment flux and runout in turbidity currents (2022)
Journal Article
Pope, E. L., Cartigny, M. J., Clare, M. A., Talling, P. J., Lintern, D. G., Vellinga, A., …Vendettuoli, D. (2022). First source-to-sink monitoring shows dense head controls sediment flux and runout in turbidity currents. Science Advances, 8(20), eabj3220. https://doi.org/10.1126/sciadv.abj3220

Until recently, despite being one of the most important sediment transport phenomena on Earth, few direct measurements of turbidity currents existed. Consequently, their structure and evolution were poorly understood, particularly whether they are de...
