Ebullition of methane from peatlands: does peat act as a signal shredder? (2015)
Journal Article
Ramirez, J. A., Baird, A. J., Coulthard, T. J., & Waddington, J. M. (2015). Ebullition of methane from peatlands: does peat act as a signal shredder?. Geophysical research letters, 42(9), 3371-3379. https://doi.org/10.1002/2015gl063469

Bubbling (ebullition) of greenhouse gases, particularly methane, from peatlands has been attributed to environmental forcings, such as changes in atmospheric pressure. However, observations from peat soils suggest that ebullition and environmental fo... Read More about Ebullition of methane from peatlands: does peat act as a signal shredder?.

Evaluating the importance of catchment hydrological parameters for urban surface water flood modelling using a simple hydro-inundation model (2015)
Journal Article
