The approach is used in order to identify important properties (e.g. circulation and precipitation) of past climatic states from the models and proxies, which is a primary objective of the Southern Hemisphere Assessment of PalaeoEnvironment (SHAPE) initiative. The AOGCM data are taken from the Paleoclimate Modelling Intercomparison Project (PMIP) mid-Holocene (ca. 6000 years before present, 6 ka) and pre-industrial control (ca. 1750 CE, 0 ka) experiments. The synthesis presented here shows that the models and proxies agree on the differences in climate state for 6 ka relative to 0 ka, when they are insolation driven. The largest uncertainty between the models and the proxies occurs over the Indo-Pacific Warm Pool (IPWP). The analysis shows that the lower temperatures in the Pacific at around 6 ka in the models may be the result of an enhancement of an existing systematic error. It is therefore difficult to decipher which one of the proxies and/or the models is correct. This study also shows that a reduction in the Equator-to-pole temperature difference in the Southern Hemisphere causes the mid-latitude westerly wind strength to reduce in the models; however, the simulated rainfall actually increases over the southern temperate zone of Australia as a result of higher convective precipitation. Such a mechanism (increased convection) may be useful for resolving disparities between different regional proxy records and model simulations. Finally, after assessing the available datasets (model and proxy), opportunities for better model-proxy integrated research are discussed. © Author(s) 2017.]]> Wed 07 Apr 2021 14:01:11 AEST ]]> Application of geogrids in waste dump stability : A numerical modeling approach http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:12288 Wed 07 Apr 2021 14:00:34 AEST ]]> Predicting site productivity of the timber tree Pterocarpus angolensis http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:12061 Wed 07 Apr 2021 14:00:22 AEST ]]> First Holocene cryptotephras in mainland Australia reported from sediments at Lake Keilambete, Victoria, Australia http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11964 Wed 07 Apr 2021 13:57:15 AEST ]]> Stable sulfur isotope dynamics in an acid sulfate soil landscape following seawater inundation http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11146 Wed 07 Apr 2021 13:56:28 AEST ]]> Cladoceran-inferred environmental change during the LGM to Holocene transition from Onepoto maar paleolake, Auckland, New Zealand http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:10911 Wed 07 Apr 2021 13:56:17 AEST ]]> A century-scale, human-induced ecohydrological evolution of wetlands of two large river basins in Australia (Murray) and China (Yangtze) http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:10684 Wed 07 Apr 2021 13:56:02 AEST ]]> A New assessment framework for transience in hydrogeological systems http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:10433 Wed 07 Apr 2021 13:55:48 AEST ]]> Using point cloud data to identify, trace, and regularize the outlines of buildings http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:10430 Wed 07 Apr 2021 13:55:47 AEST ]]> Seawater inundation of coastal floodplain sediments : Short-term changes in surface water and sediment geochemistry http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:10423 Wed 07 Apr 2021 13:55:47 AEST ]]> Liberation of acidity and arsenic from schwertmannite : Effect of fulvic acid http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:10410 Wed 07 Apr 2021 13:55:46 AEST ]]> Enrichment and heterogeneity of trace elements at the redox-interface of Fe-rich intertidal sediments http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:10399 Wed 07 Apr 2021 13:55:45 AEST ]]> Iron geochemical zonation in a tidally inundated acid sulfate soil wetland http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:10395 30mmol L-1) in former sulfuric horizons in the upper-intertidal zone. Tidal forcing generated oscillating hydraulic gradients, driving upward advection of this Fe2+-enriched porewater along the intertidal slope. Subsequent oxidation of Fe2+ led to substantial accumulation of reactive Fe(III) fractions (up to 8000μmol g-1) in redox-interfacial, tidal zone sediments. These Fe(III)-precipitates were poorly crystalline and displayed a distinct mineralisation sequence related to tidal zonation. Schwertmannite (Fe8O8(OH)6SO4) was the dominant Fe mineral phase in the upper-intertidal zone at mainly low pH (3-4). This was followed by increasing lepidocrocite (γ-FeOOH) and goethite (α-FeOOH) at circumneutral pH within lower-intertidal and subtidal zones. Relationships were evident between Fe fractions and topography. There was increasing precipitation of Fe-sulfide minerals and non-sulfidic solid-phase Fe(II) in the lower intertidal and subtidal zones. Precipitation of Fe-sulfide minerals was spatially co-incident with decreases in porewater Fe2+. A conceptual model is presented to explain the observed landscape-scale patterns of Fe mineralisation and hydro-geochemical zonation. This study provides valuable insights into the hydro-geochemical processes caused by saline tidal inundation of low lying CASS landscapes, regardless of whether inundation is an intentional strategy or due to sea-level rise. © 2010 Elsevier B.V.]]> Wed 07 Apr 2021 13:55:45 AEST ]]> Quantifying alkalinity generating processes in a tidally remediating acidic wetland http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:10393 tidal exchange (25-42%)>sulfate reduction (7-13%)>>hydrated lime addition (<1%). Accurately attributing the relative contributions due to Fe and SO 4 2- reduction was limited by an inability to distinguish between non-sulfidic, solid-phase Fe(II) generated by microbial dissimilatory reduction of Fe(III) or chemical reduction of Fe(III) by H 2S. Nevertheless, the combined alkalinity contribution of these two electron accepting processes accounts for between 58 and 74% of the total. The majority (>99%) of net alkalinity generation was due to either tides or microbial metabolism. This indicates that the LATE remediation technique is both a cost effective means of decreasing soil acidity and is readily transferable to similar CASS landscapes - provided there is adequate supply of suitable electron donors and sufficient regenerative capacity in the adjacent estuarine/marine tidal HCO 3 - pool. © 2012 Elsevier B.V.]]> Wed 07 Apr 2021 13:55:45 AEST ]]> Metal partitioning dynamics during the oxidation and acidification of sulfidic soil http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:10383 Wed 07 Apr 2021 13:55:44 AEST ]]> Mobility of arsenic and selected metals during re-flooding of iron- and organic-rich acid-sulfate soil http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:10375 Wed 07 Apr 2021 13:55:44 AEST ]]> Assessing the impact of drought and forestry on streamflows in south-eastern Australia using a physically based hydrological model http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:10239 Wed 07 Apr 2021 13:55:34 AEST ]]> Writing difference differently http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:8245 Wed 07 Apr 2021 13:53:18 AEST ]]> Expressions of climate perturbations in western ugandan crater lake sediment records during the last 1000 years http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:7667 Wed 07 Apr 2021 13:47:08 AEST ]]> Increasing the understanding and use of natural archives of ecosystem services, resilience and thresholds to improve policy, science and practice http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:7551 Wed 07 Apr 2021 13:47:00 AEST ]]> The sedimentary record of palaeoenvironments and sea-level change in the Gulf of Carpentaria, Australia, through the last glacial cycle http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:7202 Wed 07 Apr 2021 13:46:41 AEST ]]> Automatic extraction of building roofs using LIDAR data and multispectral imagery http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:6624 Wed 07 Apr 2021 13:46:12 AEST ]]> Flood vulnerabillity analysis in coastal zones : a comparative analysis across five asia-pacific countries http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:6415 Wed 07 Apr 2021 13:46:00 AEST ]]> Large versus small wood in streams : the effect of wood dimension on macroinvertebrate communities http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:6365 0.1 m diameter), excluding any smaller pieces. However, this may neglect a major component of in-stream habitat, as small wood can constitute the majority of pieces, particularly in small streams. The ecological benefit of large wood is well established, but corresponding benefits associated with small wood (0.05-0.1 m diameter) have not been demonstrated. To test the effect of wood dimension on macroinvertebrate community composition, we compared the fauna occupying large wood habitats with that occupying small wood at eight streams in south-eastern Australia. The relationships between wood dimensions and its macroinvertebrate fauna were complex. Community composition did not vary with wood dimension, and no significant correlations were found between other macroinvertebrate attributes (including family richness and evenness) and wood dimension, including diameter. However, analysis of covariance suggested that large wood supported a greater diversity and abundance of macroinvertebrates, indicating that the method of analysis could influence the result. Adjustment for differences in sample dimension using rarefaction determined that these findings were likely to be a result of the surface area and volumes sampled varying with the dimension of the wood. Per unit surface area, and per unit volume, small wood supported a similar number of families to large wood. Thus we conclude that, relative to the available surface area, small and large wood can be equivalent in their contribution to the available habitat in a stream. Therefore, the potential value of small wood as a habitat resource warrants its explicit consideration for inclusion in ecological and rehabilitation studies.]]> Wed 07 Apr 2021 13:45:57 AEST ]]> Linking soil moisture balance and source-responsive models to estimate diffuse and preferential components of groundwater recharge http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:6263 Wed 07 Apr 2021 13:45:51 AEST ]]> Diatom and stable isotope record of Late Holecene lake ontogeny at Indrepollen, Lofoten, NW Norway: a response to isostacy and neoglacial cooling http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:5181 Wed 07 Apr 2021 13:44:49 AEST ]]> Sea level trends at locations of the United States with more than 100 years of recording http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:4868 Wed 07 Apr 2021 13:44:25 AEST ]]> Oscillations of sea level rise along the Atlantic coast of North America north of Cape Hatteras http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:4867 Wed 07 Apr 2021 13:44:25 AEST ]]> Diatom-based models for inferring past water chemistry in western Ugandan crater lakes http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:4721 Wed 07 Apr 2021 13:44:15 AEST ]]> Groundwater-level response to land-use change and the implications for salinity management in the West Moorabool River catchment, Victoria, Australia http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:3784 Wed 07 Apr 2021 13:34:49 AEST ]]> Evidence for invasive carp mediated trophic cascade in shallow lakes of western Victoria, Australia http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:481 Wed 07 Apr 2021 13:31:24 AEST ]]> Macroinvertebrate communities in Phragmites australis (Cav.)
