Résumé :

Abstract. This study uses two climate models and six scenarios of prescribed methane emissions to compare modelled and observed atmospheric methane between 1994 and 2007, for Cape Grim, Australia (40.7° S, 144.7° E). The model simulations follow the TransCom-CH4 protocol and use the Australian Community Climate and Earth System Simulator (ACCESS) and the CSIRO Conformal-Cubic Atmospheric Model (CCAM). Radon is also simulated and used to reduce the impact of transport differences between the models and observations. Comparisons are made for air samples that have traversed the Australian contine

Résumé :

Feedlot management systems for beef cattle are becoming a more common practice in Australia reflecting opportunities to ensure quality of product whilst maintaining cost efficiencies within production. However, feedlot systems have been identified as point sources of greenhouse gases emissions (GGE: methane, nitrous oxide and the indirect greenhouse gas ammonia). It has been estimated that feedlot systems contribute 3.5% of total direct methane emissions (Alford et al. 2006), and 30% of total emissions from livestock wastes. Furthermore, approximately 1% of total N2O emissions from agriculture

Résumé :

Significant work is taking place in Queensland and New South Wales to make the recovery of natural gas from coal seams (Coal Seam Methane) a viable industry. At this stage there are still some daunting hurdles to overcome. Australian buyers and financiers remain sceptical on resource risk and continuity of supply issues. In the USA commercial production has been taking place for 20 years, but the industry was only able to achieve credibility and viability by relying on tax breaks. Unfortunately, the same type of government incentives are not present in Australia. Whether, in the absence of the

Résumé :

2009 saw an overall decrease from high activity from 2008, levelling off in the December quarter as the economy stabilised. Unsurprisingly, most activity was in offshore Western Australia and on coal seam methane (CSM) in Queensland. Highlights include: good results in the Carnarvon and Browse basins for Western Australian operators, interest in Karoon and Conoco-Phillips’ enigmatic Poseidon project, over 180 CSM exploration wells in Queenslandd, and a relatively busy year for Tasmania. Western Australian seismic acquisition approached 10,000 km of 2D and 25,000 km2 of 3D for 38* wells and suc

Résumé :

The flux of methane from freshwater wetlands is likely to be influenced by the presence of emergent macrophytes. The plants generate an organic loading, which should increase methanogenesis, yet they also aerate the sediment, creating oxic zones inimical to the obligately anaerobic methanogenic bacteria and promoting the oxidation of methane by methanotrophic bacteria. Moreover, emergent plants can act as a conduit for methane to be vented to the atmosphere. Depth profiles of oxygen in beds of B. arthrophylla and T. procerum at Bool Lagoon, South Australia, showed that water at the sediment su

Résumé :

Aerobic CH4 oxidation through methanotrophic bacteria is the only terrestrial sink and the only sink that can be altered directly or indirectly by human so far. However, the capacity of this sink is highly variable in different ecosystems depending on four key factors which are soil diffusivity, soil temperature, soil nitrogen status and soil moisture. While many studies in Australia experience the significant inverse correlation between soil moisture and CH4 flux magnitude in temperate forests in Victoria and New South Wales, there is a lack of research about the methane uptake capacity of ga

Coal seam gas (CSG), also known as coalbed methane (CBM), is an important source of gas supply to the liquefied natural gas (LNG) exporting facilities in eastern Australia and to the Australian domestic market. In late 2018, Australia became the largest exporter of LNG in the world. 29% of the country’s LNG nameplate capacity is in three east coast facilities that are supplied primarily by coal seam gas. Six geological basins including Bowen, Sydney, Gunnedah, Surat, Cooper and Gloucester host the majority of CSG resources in Australia. The Bowen and Surat basins contain an estimated 40Tcf of

Résumé :

Abstract. Well-drained, aerated soils are important sinks for atmospheric methane (CH4) via the process of CH4 oxidation by methane-oxidising bacteria (MOB). This terrestrial CH4 sink may contribute towards climate change mitigation, but the impact of changing soil moisture and temperature regimes on CH4 uptake is not well understood in all ecosystems. Soils in temperate forest ecosystems are the greatest terrestrial CH4 sink globally. Under predicted climate change scenarios, temperate eucalypt forests in south-eastern Australia are predicted to experience rapid and extreme changes in rainfal

Résumé :

The history of methadone treatment in Australia has been and continues to be marked by conflict between two competing aims: harm minimisation and abstinence. The two approaches tend to be associated with high dose-long term and low dose-short term treatment, respectively. Most programmes fail to provide adequate ancillary services, often to the detriment of patient outcome. Despite chronic under-funding, a relative lack of staff training and, in some states, the absence of a system of clinical accountability, Australian methadone services have grown significantly in the last decade.

Résumé :

The coal seams of the coal basins in New South Wales contain vast resources of methane. The gas has been of interest in the past, principally because the inflow of significant quantities into coal mine workings is a danger to mine safety and reduces production. Drainage techniques have been introduced into deeper collieries but they have not proved to be totally effective.Surface pre-drainage operations using hydraulic fracturing to stimulate gas production have been successful in the United States over recent years. The technique has yet to be successfully tested in New South Wales but if eff

Résumé :

A rapid and sensitive method is described for the extraction, detection and measurement of corynetoxins in ryegrass seed galls colonized by Corynebucterium rathayi. Excised galls are extracted with aqueous methanol and the extract analysed, without further purification, by reversed-phase high-performance liquid chromatography with detection by uItraviolet absorption. The method is applicable down to the level of a single gall or part of a gall with a minimum level of detection of about 0.25 �g using the equipment described. The corynetoxin content of the individual galls examined varied from b

Résumé :

Feedlot production of beef cattle results in concentrated sources of gas emissions to the atmosphere. Reported here are the preliminary results of a micrometeorological study using open-path concentration measurements to determine whole-of-feedlot emissions of methane (CH4) and ammonia (NH3). Tunable near-infrared diode lasers were used to measure line-averaged (150–400 m) open-path concentrations of CH4 and NH3. A backward Lagrangian stochastic model of atmospheric dispersion and the software package WindTrax were used to estimate greenhouse gas fluxes from the measured concentrations. We stu

Résumé :

More than 13 morphospecies of fungal endophyte were isolated from leaves of cotton collected from eastern New South Wales, Australia. Of the fungi tested, methanol extracts of 4 morphospecies offered with a food source reduced the larval growth rate of the insect pest Helicoverpa armigera. Extracts of different isolates of 1�common morphospecies had varying effects on growth rates of H. armigera and H. punctigera. The impact of the endophytes after inoculation to leaves of cotton also differed. Five of 10 selected isolates were associated with reduced feeding from leaf discs in a feeding-choic
