Forwarded from CLIMLIST... We are inviting applications for a PhD studentship to commence 1 March 2012 in the general area of tropical paleohydrology and the global carbon cycle. Two potential projects are outlined below. The studentship will cover UK/EU tuition fees plus an annual stipend of £13,590pa for three years and will be awarded on the basis of merit. International fee-paying students are eligible to apply but will be required to pay the difference between the award and the international fee. Supervisors: Professor Dan Charman <http://geography.exeter.ac.uk/staff/index.php?web_id=Daniel_Charman> (Geography), Dr Hugo Lambert <http://emps.exeter.ac.uk/mathematics-computer-science/staff/fhl202> (Mathematics and Computer Sciences) (1) The link between tropical peatland palaeohydrology and the global carbon cycle Peatlands play an important role in the global carbon cycle. They hold around a third of global soil carbon, sequester carbon dioxide from the atmosphere, and produce methane through anaerobic decay. Tropical peatlands are thought to be especially important for methane emissions but rather little is known about the past hydrological changes that are a key driver of methanogenesis and other phenomena related to the carbon cycle. The project will involve development of new palaeohydrological records from Indonesian peatlands that are being studied as part of a larger NERC-funded project, focusing especially on the last millennium. These will be used alongside other proxy records to assess the extent to which tropical peatland hydrology is linked to large-scale patterns of hydrological variability and change during the Holocene and to estimate the contribution of tropical wetlands to past global methane emissions. For informal enquiries on this project, contact Professor Dan Charman at <firstname.lastname@example.org>. (2) Understanding Holocene tropical hydrological change and variability Understanding past climatic variability and change are an important part of efforts to project future changes in climate. Past climatic behaviour is estimated from proxy data such as tree rings and ice cores that primarily describe changes in temperature. This project will involve using new proxies under development at the University of Exeter linked to the hydrological cycle to understand changes in precipitation. Using statistical techniques such as those recently applied to the relationship between 20th century raingauge data and known patterns of large-scale precipitation variability, the student will investigate the extent to which proxy records can be linked to Holocene precipitation variability and change. The particular focus will be on South East Asia, where it is expected that variability due to the El Nino Southern Oscillation will be of paramount importance. This is particularly interesting as changes in the character of El Nino are apparent from Holocene records, but not well understood. Estimating hydrological changes in the region will also help us understand carbon uptake and carbon dioxide and methane emission by tropical peatlands that presently contain around a third of the world's soil carbon. For informal enquiries on this project, contact Dr Hugo Lambert at <email@example.com>. Application criteria The successful applicant should have or expect to achieve at least an Upper Second Class Honours degree, or equivalent qualifications in geography, ecology, earth sciences, mathematics, physics, meteorology or a related discipline. Experience in palaeoenvironmental techniques and an understanding of Quaternary climate change are essential for project (1). Some experience in computer programming is essential for project (2). An interest in climate change is highly desirable for both.We are inviting applications for a PhD studentship to commence 1 March 2012 in the general area of tropical paleohydrology and the global carbon cycle.
