Introduction

Long-lived radionuclides released from an underground nuclear waste repository may reach the surface ecosystem via the groundwater and, therefore, constitute a potential risk for humans and biota through different pathways. Due to their perennial character, forest vegetation or perennial vegetation systems in general, may affect radionuclide dispersion and distribution in the biosphere in the long-term. The purpose of this project is to contribute to the development of a Soil-Vegetation-Atmosphere Transfer (SVAT)model to quantify this problem, aiding the assessment of long-term risks related to deep nuclear disposal.

Post-Doctoral Research Project Title: Assessing trace gas fluxes from agricultural systems

Project Description

The BioClim Action of the Climate Change and Air Quality Unit analyses on the effectiveness of EU and global policies that potentially impact the cycling of carbon and nitrogen compounds between the atmosphere and the biosphere. We are looking for a researcher to perform assessments of trace gas fluxes from terrestrial ecosystems in Europe with a focus on agricultural sources. In the context of the project, the objective is to:

Contribute to the improvement of models that comprehensive­ly assess the turnover and losses of nitrogen and carbon in agricultural systems at the regional scale

OCE Postdoctoral Fellow - A rational scheme for assessing greenhouse gas emissions from irrigated agriculture

CSIRO Land and Water is seeking to appoint a highly motivated postgraduate with extensive experience in the area of greenhouse gas emission measurement linked to ecohydrology of agroecosystems. The OCE Postdoctoral FellowshipScheme provides an opportunity to undertake postdoctoral research projects aligned with the best research teams across CSIRO. This particular project also provides opportunity to work with a multi-disciplinary team of scientists of the highest calibre in the area of agricultural greenhouse gas research from other organisations in Australia, Germany and New Zealand.

T5.4 Modelling Vegetation-Atmosphere Feedbacks in the Amazon Region

Nitrous oxide (N2O) is an important greenhouse gas and agricultural soils are the largest source. Flux measurements are usually made using small chambers and then scaled up to the field, farm and even national scale using very simple mathematical equations. This process is highly uncertain and needs to be verified by more sophisticated measurements. The objectives of this PhD project are to verify the upscaling from small plots to the field and farm scale.  You will do this by comparing small chamber measurements with field scale eddy covariance measurements using a quantum cascade and tunable diode laser spectrophotometer over a grazed grassland very close to our institute.
