BOGS 2017

The Open University is hosting the annual meeting on the British Organic Geochemical Society on the 27th & 28th June 2017. For more information please see our BOGS2017 website here

 

I’m a Lecturer in Earth Sciences in the School of Environment, Earth and Ecosystem Sciences at The Open University, I am also Visiting Senior Research Associate in the Organic Geochemistry Unit at the University of Bristol. My research concentrates on exploring the links between the Earth’s carbon cycle and climate on Cenozoic timescales, and I deploy a range of tools including organic geochemistry, foraminiferal geochemistry and General Circulation Models.

I graduated from Jesus College, University of Oxford with an MEarthSci (Hons) in Earth Sciences in 2005. Whilst there I worked on the prospects of developing a sea surface temperature proxy using stable strontium isotopes in coccolithophores calcite analysed by multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS). The project was supervised by Dr Ros Rickaby.

In 2005 I moved to the school of Earth and Ocean Sciences, Cardiff University to conduct my doctoral research into middle Miocene climate dynamics, supervised by Dr Carrie Lear (Cardiff) and Prof Rich Pancost (Bristol). Using coupled organic and inorganic climate proxies, I constructed high resolution records of atmospheric pCO2 (alkenone and boron isotopes) and sea surface temperatures (foraminifera Mg/Ca and alkenone unsaturation indices). These proxy records, coupled with carbon system models and carbonate stable isotopes, allowed me insight into carbon cycle dynamics at a critical interval of major ice sheet growth in Antarctica. My PhD was awarded in 2010.

Following my PhD I moved to the Organic Geochemistry Unit in the School of Chemistry to work with Prof. Rich Pancost as a postdoc. I've worked on a number of grants with Rich, developing records climate and environmental change at various times through the Cenozoic, working mainly with hyphenated techniques (GC-MS, LC-MS, GC-C-IRMS).

In October 2011 I moved to the department of Earth Sciences for a stint as a lecturer, before returning to the OGU to take up a post as a Senior Research Associate in March 2013. Research during this time focussed on terrestrial methane cycling during Paleogene greenhouse climates, which involved collaborative work using the Unified Model with colleagues from the BRIDGE group (Paul Valdes) alongside organic geochemical approaches.

Much of my research focusses on sediments recovered from the ocean floor, and in autumn 2013 I took a short break from the OGU to participate in the TROPICS research expedition aboard the RRS James Cook (pictured above). Details of the expedition can be found here:  http://tropics.blogs.ilrt.org/.

I moved to School of Environment, Earth and Ecosystem Sciences at The Open University in March 2016.

I'm back to sea again in the summer of 2017, this time aboard the RRS Discovery to the Labrador Sea to participate in the European Research Council funded ICY-LAB project lead by Dr Kate Hendry from the University of Bristol. The expedition aims to increase our understanding of nutrient supply in the oceans. More details can be found on the project website: https://icylab.wordpress.com/.

Research interests

I study ancient climates using molecular fossils. When an organism dies, often components of the organic remains are preserved in sediments. By analysing molecules characteristic of particular organisms or environmental conditions (“biomarkers”) we can reconstruct ancient environmental parameters. My research primarily uses organic geochemical proxies analysed by GC, GC-MS, LC-MS and GC-C-IRMS to reconstruct sea surface temperatures (TEX86 and UK'37) and atmospheric pCO2 (alkenone δ13C) along with other key indicators of past climates.

I believe in a multi-proxy approach and so also utilise more ‘traditional’ inorganic proxies, based on the skeletal remains, such as planktonic foraminiferal Mg/Ca, δ13C and δ18O. My research focuses on key periods in the Cenozoic (the last 65 million years) including the middle Miocene Climate Transition (when large ice sheets first appeared on East Antarctica), the warm Pliocene (one of the best partial analogues for future anthropogenic warmth) and the PETM (Paleocene-Eocene Thermal Maximum).

My current research focus is on using a three dimensional coupled model approach to investigate terrestrial methane cycling during Paleogene greenhouse climates, which will be combined with organic geochemical investigations of methane production using a global suite of lignites.

New capabilities

I'm currently setting up new (to the OU) processes in my labs and am interested in finding new collaborators! We have fantastic facilities and capabilities to run foraminiferal trace metal and organic geochemical analyses including lipid analyses by GC, GC-MS and GC-C-IRMS and GDGT analyses by HPLC-MS. If you have exciting ideas and samples get in touch!

Teaching interests

The Earth in My Pocket: An Introduction to Geology

I wrote the Future Learn MOOC "The Earth in My Pocket: An Introduction to Geology" with Dr Anne Jay in 2016. Get an introduction to geology. Discover where materials that make up everyday objects come from and how to use them sustainably. Sign up now for the first run in February 2017!

Earth Processes (S309)

I'm a guest author on the level three module "Earth Processes (S309)", and wrote sections on the Intergovernmental Panel on Climate Change (IPCC) for the science in society module in 2016. The course is one of the first OU courses to use direct authoring on the OpenEdx platform.

Science: Concepts and Practices (S112)

I'm a core author on this new first year module which will provide a solid toolbox of knowledge, understanding, and skills for science students across the university. I'm writing material on environmental change, living in a changing climate, and contributing material for other earth science sections of the module.

Ecosystems (S396)

I'm on the module team rewriting the level three module "Ecosystems". We're just starting and the first learning design workshop is early in 2017. We're all excited to refresh what has been a very popular module and make it fit for online delivery.
