I am ecosystem scientist interested in the how our changing use of the planet is altering the functioning of the terrestrial biosphere and its interactions with the atmosphere (My Exeter homepage). I am based in the University of Exeter’s Geography department (Geography at Exeter), where I teach computing and land-atmosphere interactions to our Physical Geography students and coordinate an informal research group focusing on ecosystem ecology.
My research is diverse, taking me to field sites in Africa, America, Asia and sometimes I even stay in the UK! The ecosystems I work on include: agricultural systems, drylands, saltmarshes, temperate peatlands, tropical forests and tropical peat systems (including oil palm plantations). Much of my research focuses on stocks and fluxes of carbon, energy and water – but I am also interested in other trace gases and even lightning!
To study these ecosystems, I employ field measurements, remote sensing and models. Often, my research makes use of the use of Eddy Covariance technique. Increasingly, I have found my attempts to answer key research questions has led me to develop custom eddy covariance systems. These new systems either expand the range of greenhouse gases measured, or to reduce instrumentation costs to facilitate true spatial replication using eddy covariance.
We have just been back to Malaysia to perform routine maintance on the towers – you know the sort of thing: lightning damage, ant infestations etc… The most notable change though was how much the growth of the three year conversion palms has accelerated.
We have reached another milestone! The Los Gatos (methane and nitrous oxide) sensor is being moved into its new home in the logged peat swamp forest. The sensor will be monitoring greenhouse gasses from the logged peatswamp forest.
We have been back in the field establishing the new 50 ha plot in Ankasa, Ghana. I have also been helping out Silvio Stivanello with the electrical resistivity measurements on the sample trees. As you might have guessed, I am not the one who should be taking credit for the work! That goes to Dr […]
