I am a Physical Geographer and Quaternary Scientist. From September, 2014 I will be based in the Geography department at the University of Manchester from September as a Lecturer in Physical Geography.
My research interests lie within understanding the dynamics of dryland systems, including environmental change, landscape dynamics and groundwater resources.
I am interested in these processes and dynamics over a range of timescales and address two broad themes:
CURRENT RESEARCH PROJECTS
1) Chemical Tracers as novel archives
A) Rainfall in the desert sand
Thesiger-Oman International Fellowship from the Royal Geographic Society I sampled linear dunes above the Stampriet Aquifer in southern Namibia to investigate rates of recharge to groundwater over the past few decades in the region. The data also provides a record of relative moisture changes through time, which is a novel proxy for moisture availability in the desert environment. Read research report.
And thanks also to the British Society for Geomorphology, who have awarded me a small Reseach Grant, which completed funding for the first phase of fieldwork and laboratory analysis.
The second phase of fieldwork started in April, 2013, and investigates whether geomorphological setting controls variations in the records preserved. Thanks to the Quaternary Research Association for funding towards this second phase.
B) Palaeomoisture records in the sandy deserts
With Mike Edmunds I am reviewing the application and developments of using chemical proxies in sand dunes and sediments (the unsaturated zone) as novel proxies for past moisture availability.
2) Quaternary environmental dynamics using geoproxies
A) Casting new light on Quaternary environmental change in the Namib Desert.
Journal of Arid Environments, and chapter in The CHANGING DESERTS - Integrating people and their environments book.
Have a look at the coverage on BBC Earth News, and Oxford Uni news on the Oxford Deserts conference featuring pictures from my fieldwork in the Namib Desert.
B) Dating generations of dunes

I am the course leader for this new option course for third year students. Follow tweets (@AbiStone relevant to the course #DPPF2015)
As a visiting research associate at the University of Oxford I contribute a lecture on Hydrogeology for the Climate and Catchment Processes module on the Water Science Policy and Management MSc.
Previously I taught Physical Geography at the University of Oxford, most recently at St John's College. This included:
I was also a tutor for the Quaternary Period and Dryland Environments special subjects for Final Honours School at the School of Geography and the Environment.
1) RECENT CONFERENCES relating to research on using the portable luminescence reader as applied to the sediments of the Namib Sand Sea.
This started with a comparison of portable reader and full OSL dating for samples taken from a transect across a linear dune in the south of the sand sea (of Holocene age) and has progressed to a comparison of the two methods for two sites and samples spanning, near-modern, late Holocene and into the last interglacial (100, 000 years plus).
2) RECENT PUBLICATIONS on southern African Quaternary environments
3) GROUNDWATER and the UNSATURATED ZONE in drylands
On 29th October I am attending The Nitrogen Cycle and the Anthropocene at BSG, Keyworth, Nottingham, where I will present a poster on this same paper.

Quaternary Science and Soil/Sand Gets Speedy
My colleauge Matt was contacted by these speed-seekers, who want to understand more about the composition of the pan surface in South Africa they plan to tear across with a hybrid rocket and Eurofighter-Typhoon jet engine! ZOOM...
Gobabeb - 50 years persistent research and fascination
A wonderful place in the desert, hosting both SAAG and SAASQUA conferences in 2012. As part of the celebrations (and to honour Mary Seely's 70th Birthday) I have paper in JofAE.
