Isotopically resolved fate and processes of nitrogen in a constructed wetland treating domestic effluent Open
Constructed wetlands (CWs) are recognised as effective wastewater purification systems for the removal of contaminants, particularly nitrogen (N). However, the performance of a CW in N removal relies on complex biogeochemical interactions …

Water-extractable alkalinity to estimate the acid-neutralising capacity of organic amendments Open
The effectiveness of amendments to increase the pH of an acidic soil can be expressed as acid-neutralizing capacity (ANC). The alkalinity measurement method, based on prolonged hydrolysis of organic amendments with acid, is widely used but…

A Review of <span>Fe–S–C</span> Dynamics in Blue Carbon Environments: Potential Influence of Coastal Acid Sulfate Soils Open
Vegetated blue carbon environments have the potential to sequester large amounts of carbon due to their high productivity and typically saturated, anaerobic soils that promote carbon accumulation. Despite this, and the coupling of Fe–S–C c…

Organic matter accumulation drives methylotrophic methanogenesis and microbial ecology in a hypersaline coastal lagoon Open
Hypersalinity is common in coastal wetlands throughout warm, tropical, and arid regions. Climate‐induced changes in rainfall, sea level, and anthropogenic modification to basins and coastlines are likely to further increase salinization in…

Impact of hydrological drought occurrence, duration, and severity on Murray-Darling basin water quality Open
The severity and frequency of droughts are projected to increase globally due to climate change, but the effects of this on water quality are uncertain. The Murray-Darling Basin (MDB) is the largest river system in Australia and has been i…
