[资源] 【招聘】Two PhD opportunities from University of Wollongong

University of Wollongong
School of Earth and Environmental Sciences
Two PhD opportunities in Isotope Geochemistry

Contact: Dr Anthony Dosseto (tonyd@uow.edu.au), GeoQuEST Research Centre, School of Earth and Environmental Sciences, University of Wollongong (NSW, Australia)

There are currently 2 PhD opportunities at the University of Wollongong in the field of isotope geochemistry applied to landscape evolution, paleoclimate and soil processes. The applicant should have a B.Sc. with Honours 1st class or equivalent, or a Masters degree or equivalent. He/she should also have some knowledge of isotope geochemistry, low temperature geochemistry (chemical weathering, soil processes) and if possible lab experience, particularly in mass spectrometry.

Scholarships cover tuition fees and living allowance for the duration of the project (3 years).

The School of Earth and Environmental Sciences has a strong international reputation in several fields including Quaternary Science and Geochemistry. Facilities include a brand new isotope geochemistry laboratory, sedimentary and environmental labs, XRF, XRD, quadrupole ICP-MS, stable isotope mass spectrometer.

Wollongong is located 80km (50mi) south of Sydney, right on the coast. It benefits from a great weather all year round, the proximity of great hiking trails and some of the best surf spots in the country (the university is located 10min from the beach)! With 26,000 students at the University of Wollongong (of which almost ½ of it are international students), i.e. ~10% of the town population, Wollongong also has the exciting nightlife of a surf/student town.

Project title: The role of climate and time on soil formation in Hawai'i

Project description: Civilizations rely (partly) on their ability to sustain soil resources. Thus, it is important to be able to quantify how fast soil is produced and what controls rates of soil production. This project will investigate the role of climate and time on soil formation in Hawai'i by studying profiles developed on lava flows on varying age and under a wide range of annual rainfall. Uranium-series isotopes will be used along with other geochemical data to infer rates of soil development, assess how these rates change with the maturity of the profile (i.e. varying substratum age) and with varying annual rainfalls. Expect some fieldwork in Hawai'i. Proposed starting date: March 2011

Project title: The response of erosion and chemical weathering to past climate change

Project description: In a world where climate is changing rapidly, it is important to understand how climate variability impacts our soil and water resources. A possible approach is to look how in the past, sediments have recorded this variability. The project will use uranium-series and lithium isotopes in sedimentary records to quantify how physical erosion and chemical weathering have adapted to past changes in climatic conditions. Study sites are in the Himalayas (India), northern and southern Australia, Tasmania and New Zealand. Fieldwork in India, Australia and New Zealand is to be expected. Proposed starting date: August 2011
