MEGA-MOBILE ECOSYSTEM GAS-EXCHANGE ANALYSER FOR AUSTRALIAN LANDSCAPES
Grant number: LE0882936 | Funding period: 2008 - 2008
This Mobile Ecosystem Gas-exchange Analyser will be able to continuously monitor water, energy, carbon and nitrogen exchange in a multitude of uniquely Australian ecosystems: from low-canopy forests (up to 20m) and afforested plantations to wetlands and agricultural grazing, cropping, horticulture and viticulture systems. This research capacity provides benefits and opportunities such as 1) community resource 2) monitoring tool for carbon and water budgets 3) mobile process laboratory 4) data for model validation. The susceptibility and vulnerability of ecosystems to changing temperature and extended drought will be determined.
