Site Description

The Fogg Dam flux station was located approximately 6km east of Black Jungle, Northern Territory (GPS coordinates: -12.5452, 131.3072).

The flux tower site was classified as a seasonally flooded wetland. The vegetation was dominated by species Oryza rufipogon, Pseudoraphis spinescens and Eleocharis dulcis. Elevation of the site was close to 4m and mean annual precipitation from a nearby Bureau of Meteorology site measured 1411mm.

Maximum temperatures ranged from 31.3°C (in June and July) to 35.6°C (in October), while minimum temperatures ranged from 14.9°C (in July) to 23.9°C (in December and February). Maximum temperatures varied on a seasonal basis by approximately 4.3°C and minimum temperatures by 9.0°C.

The instrument mast was 15m tall. Heat, water vapour and carbon dioxide measurements are taken using the open-path eddy flux technique. Temperature, humidity, wind speed, wind direction, rainfall, incoming and reflected shortwave radiation and net radiation were measured above the canopy. Soil heat fluxes were measured and soil moisture content was gathered using time domain reflectometry.

Ancillary measurements taken at the site include LAI, leaf-scale physiological properties (gas exchange, leaf isotope ratios, N and chlorophyll concentrations), vegetation optical properties and soil physical properties. Airborne based remote sensing (Lidar and hyperspectral measurements) was carried out across the transect in September 2008.
