A total of 186 porewater samples were collected from Cape Bowling Green, Gordon Creek, the Townsville Town Common, and the adjacent area of Mt. Low, dissolved concentrations of Fe², Mn², Ca², Na+, K+, Sr², Rb+ and Ba² were measured. \u0000 \u0000The mangrove swamp sediments have a neutral pH (ca.pH 6.9) and reducing (ca. Eh – 250mV) and the salt flats are very slightly basic (ca. pH 7.3) and oxidizing (ca. Eh +100mV), reflecting a general increase of redox potential with increasing elevation. Similarly, increasing salinity landward across the intertidal region is reflected in the porewater sale (Ca², Mg²+, Na+, K+) concentrations and associated presence of evaporate minerals (halite , gypsum, jarosite). However, early depletion of salts indicate that evaporation trends do not simply reflect seawater concentration, but also clay mineral absorption and metabolic uptake by mangrove and samphire vegetation. \u0000 \u0000Overall, geochemical trends across the intertidal zone reflect a continuum of physical (e.g. transport and evaporation) and superimposed chemical (diagenetic) processes between the marine and terrestrial environments. The unstable mineralogy and non-linear evaporation trends, indicate that the intertidal zone is more complex than expected from simple thermodynamic modeling.","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130087146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jacobs","doi":"10.31646/WA.250","DOIUrl":"https://doi.org/10.31646/WA.250","url":null,"abstract":"To protect and manage wetlands there is a n eed for scientifically rigorous and reproducible techniques to assess their ‘health’ or ‘condition’. Any technique must be tested for robustness of method on a range of wetland types. Optimum sampling methods need to be assessed, for example, the relative benefits of cover class versus presence/absence; the consequences of misidentification at the species level, genus level and at the native versus introduced level; and the comparisons of results from using identifications above the species level as input data. The different methods now in use need to be reviewed and compared to determine whether they are additive (i.e. the corroborate) or contradictory or whether they each perform better under certain conditions. We need to be able to compare assessments using different methods on the same wetland over time. This project aims to address these questions. Early results show a large difference in species area curves for plant sampling from different wetlands, and difficulties in adapting published invertebrate sampling methods (AUSRIVAS) for wetlands, making it clear that one ‘standard’ method may never be enough. The ideal outcome of this project will be a list of methods to choose from for various situations.","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"418 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115905543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
