Calibration of the B/Ca proxy in the planktic foraminifer Orbulina universa to Paleocene seawater conditions
(2017-06) - Journal article,
The B/Ca ratio of planktic foraminiferal calcite, a proxy for the surface ocean carbonate system, displays large negative excursions during the Paleocene-Eocene Thermal Maximum (PETM, 55.9 Ma), consistent with rapid ocean ...
What a difference a stochastic process makes : epidemiological-based real options models of optimal treatment of disease
(2018-07) - Journal article,
The real options approach has been used within environmental economics to investigate the impact of uncertainty on the optimal timing of control measures to minimise the impacts of invasive species, including pests and ...

A new high-precision 40Ar/39Ar age for the Rochechouart impact structure : at least 5 Ma older than the Triassic–Jurassic boundary
(2017-08-02) - Journal article,
The Rochechourt impact structure in south-central France, with maximum diameter of 40–50 km, has previously been dated to within 1% uncertainty of the Triassic–Jurassic boundary, at which time ~30% of global genera became ...
Late Quaternary glaciation in the Hebrides sector of the continental shelf : cosmogenic nuclide dating of glacial events on the St Kilda archipelago
(2017-10) - Journal article,
The St Kilda archipelago lies ~65 km west of the Outer Hebrides and ~60 km east of the Atlantic shelf break, and represents a key site for testing the assertion that during the Last Local Glacial Maximum (LLGM; c. 27 ka) ...
Satellite observations of fumarole activity at Aluto volcano, Ethiopia : implications for geothermal monitoring and volcanic hazard
(2017-07-15) - Journal article,
Fumaroles are the surface manifestation of hydrothermal circulation and can be influenced by magmatic, hydrothermal, hydrological and tectonic processes. This study investigates the temporal changes in fumarole temperatures ...
Divergent visions of wildness in a storied landscape : practices and discourses of rewilding in Scotland's wild places
