This well, and well GM1193, occur in a sandy area of the aquifer where pumping rates and recharge are likely to be relatively higher than areas around Dalby; this could explain slightly higher DO concentrations (Fig. 7a). Methanogenesis may also persist in the presence of low DO ...
Author(s): Cook, PG; Lamontagne, S; Berhane, D; Clark, JF | Abstract: Groundwater discharge to the Cockburn River, southeast Australia, has been estimated from comparison of natural 222Rn activities in groundwater and river water, interpreted using a numerical flow model that simulates ...
9, highlight the increased sorption capacity of CO2 in comparison to CH4. With reference to the isotherms for CO2 and CH4 presented in Fig. 9, considering the measurement of gas content is the principal measure of outburst risk; for a given gas content value the isotherms indicate the gas ...
Nonetheless, the methane hy- drates break down when the water temperature goes up. This leads to natural gas release and underwater landslide. Methane hydrates form in permafrost ecosystems so that bodies of water freeze and water molecules make singular enclosures (cages) around every molecule of...
Emission rates were based on Australian nitrous oxide measurement data from Galbally et al. (2010). << Insert Table 2 around here >> 2.3 Handling co-production Both farms produced products other than wool. The NSW farm grazed steers in addition to the sheep flock and the WA farm produced ...
A comparison of Scenarios 1 and 2 is interesting from another perspective: it illustrates the effect of including or excluding certain coupled soil processes on soil water balance components. Scenario 1 has a standard advection–dispersion solute transport model without major ion chemistry; the irrigati...
First, we consider the measurement of individual fluxes, using the existing measurements by Borexino as a point of comparison. Again, we do not anticipate that this technology will be more competitive than Borexino, as it is smaller-scale and intended to be a multi-purpose instrument, but a ...

The expected increases in severity, frequency and duration of drought periods would likely have a significant impact on tree growth, mortality rates, and forest composition39. Although the temperate mesic forests of the northeastern US have not experienced severe and long-lasting drought since the ...
