Marine gas hydrate is the largest carbon reservoir in the global organic carbon cycle, but there is limited knowledge of how hydrate is accreted in space and time. Three-dimensional seismic imaging of the dipping base of the deep-water marine gas hyd...

A 5-year study of the impact of peatland revegetation upon DOC concentrations (2014)
Journal Article

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...

On the Use of Fractal Surfaces to Understand Seismic Wave Propagation in Layered Basalt Sequences (2014)
Journal Article
Nelson, C. E., Hobbs, R. W., & Rusch, R. (2015). On the Use of Fractal Surfaces to Understand Seismic Wave Propagation in Layered Basalt Sequences. Pure and Applied Geophysics, 172(7), 1879-1892. https://doi.org/10.1007/s00024-014-0986-5

The aim of this study is to better understand how a layered basalt sequence affects the propagation of a seismic wave, which has implications for sub-basalt seismic imaging. This is achieved by the construction of detailed, realistic models of basalt... Read More about On the Use of Fractal Surfaces to Understand Seismic Wave Propagation in Layered Basalt Sequences.

The fluvial flux of particulate organic matter from the UK: Quantifying in-stream losses and carbon sinks (2014)
Journal Article

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

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...

Lower crustal assimilation in oceanic arcs: Insights from an osmium isotopic study of the Lesser Antilles (2014)
Journal Article

We present whole rock 187Os/188Os data for the most mafic lavas along the Lesser Antilles arc (MgO = 5–17 wt.%) and for the subducting basalt and sediments. 187Os/188Os ratios vary from 0.127 to 0.202 in the arc lavas. Inverse correlations between 18... Read More about Lower crustal assimilation in oceanic arcs: Insights from an osmium isotopic study of the Lesser Antilles.

Power production via North Sea Hot Brines (2014)

Traditionally the power demand of offshore oil platforms is delivered by on-platform gas turbines. Natural gas to fuel these turbines is usually separated from the produced oil. However, in ageing fields as oil production declines so does the associa... Read More about Power production via North Sea Hot Brines.
