A 5-year study of the impact of peatland revegetation upon DOC concentrations (2014)
Journal Article
Qassim, S., Dixon, S., Rowson, J., Worrall, F., Evans, M., & Bonn, A. (2014). A 5-year study of the impact of peatland revegetation upon DOC concentrations. Journal of Hydrology, 519(Part D), 3578-3590. https://doi.org/10.1016/j.jhydrol.2014.11.014

Peatlands are among the largest long-term soil carbon stores on the globe, but their degradation can lead to significant carbon losses. Therefore, restoration of peatlands has received considerable attention but the impact of revegetation upon critic...

The fluvial flux of particulate organic matter from the UK: Quantifying in-stream losses and carbon sinks (2014)
Journal Article
Worrall, F., Burt, T., & Howden, N. (2014). The fluvial flux of particulate organic matter from the UK: Quantifying in-stream losses and carbon sinks. Journal of Hydrology, 519(Part A), 611-625. https://doi.org/10.1016/j.jhydrol.2014.07.051

This study considers records of fluvial suspended sediment concentration and its organic matter content from across the United Kingdom from 1974 to 2010. Suspended sediment, mineral concentration and river flow data were used to estimate the particul...

Variation in suspended sediment yield across the UK – A failure of the concept and interpretation of the sediment delivery ratio (2014)
Journal Article
Worrall, F., Burt, T., Howden, N., & Hancock, G. (2014). Variation in suspended sediment yield across the UK – A failure of the concept and interpretation of the sediment delivery ratio. Journal of Hydrology, 519(Part B), 1985-1996. https://doi.org/10.1016/j.jhydrol.2014.09.066

The sediment delivery ratio (SDR) has been a common approach developed to understand change in sediment yield and flux through a catchment. In this study we propose that the underlying concept of the sediment delivery ratio is flawed for a number of...

Modeling the rate of turnover of DOC and particulate organic carbon in a UK, peat-hosted stream: Including diurnal cycling in short-residence time systems (2014)
Journal Article
Worrall, F., & Moody, C. (2014). Modeling the rate of turnover of DOC and particulate organic carbon in a UK, peat-hosted stream: Including diurnal cycling in short-residence time systems. Journal of Geophysical Research: Biogeosciences, 119(10), 1934-1946. https://doi.org/10.1002/2014jg002671

This study proposes a multicomponent, multiprocess scheme to explain the turnover of organic matter (particulate and dissolved organic matter) in streams. The scheme allows for production and degradation of organic matter by both photic and aphotic p...

The flux of radionuclides in flowback fluid from shale gas exploitation (2014)
Journal Article
Almond, S., Clancy, S., Davies, R., & Worrall, F. (2014). The flux of radionuclides in flowback fluid from shale gas exploitation. Environmental Science and Pollution Research, 21(21), 12316-12324. https://doi.org/10.1007/s11356-014-3118-y

This study considers the flux of radioactivity in flowback fluid from shale gas development in three areas: the Carboniferous, Bowland Shale, UK; the Silurian Shale, Poland; and the Carboniferous Barnett Shale, USA. The radioactive flux from these ba... Read More about The flux of radionuclides in flowback fluid from shale gas exploitation.

Salt marshes in the silica budget of the North Sea (2014)
Journal Article
Moosdorf, N., Weiss, A., Müller, F., Lauerwald, R., Hartmann, J., & Worrall, F. (2014). Salt marshes in the silica budget of the North Sea. Continental Shelf Research, 82, 31-36. https://doi.org/10.1016/j.csr.2014.04.009

Local scale studies reported the silica recycling of salt marshes to substantially attenuate the dissolved silica (DSi) limitation in coastal waters during summer. To assess the importance of salt marshes in the silica budget of the North Sea, we ext... Read More about Salt marshes in the silica budget of the North Sea.

Potential use of heather, Calluna vulgaris, as a bioenergy crop (2014)
Journal Article
Worrall, F., & Clay, G. (2014). Potential use of heather, Calluna vulgaris, as a bioenergy crop. Biomass and Bioenergy, 64, 140-151. https://doi.org/10.1016/j.biombioe.2014.03.007

Calluna vulgaris can and does grow in areas considered unsuitable for production of biomass crops. In the UK, Calluna vegetation is regularly controlled by burn management and if instead the lost biomass could be harvested would it represent a viable...

A model of potential carbon dioxide efflux from surface water across England and Wales using headwater stream survey data and landscape predictors (2014)
Journal Article
Rawlins, B., Palumbo-Roe, B., Gooddy, D., Worrall, F., & Smith, H. (2014). A model of potential carbon dioxide efflux from surface water across England and Wales using headwater stream survey data and landscape predictors. Biogeosciences, 11(7), 1911-1925. https://doi.org/10.5194/bg-11-1911-2014

Measurements of CO2 partial pressures (pCO2) in small headwater streams are useful for predicting potential CO2 efflux because they provide a single concentration representing a mixture from different hydrological pathways and sources in the catchmen...

Oil and gas wells and their integrity: Implications for shale and unconventional resource exploitation (2014)
Journal Article

Data from around the world (Australia, Austria, Bahrain, Brazil, Canada, the Netherlands, Poland, the UK and the USA) show that more than four million onshore hydrocarbon wells have been drilled globally. Here we assess all the reliable datasets (25)... Read More about Oil and gas wells and their integrity: Implications for shale and unconventional resource exploitation.
