New approaches to investigate and construct biogeochemical models of inland acid sulfate soils: linkages to environmental degradation processes and mineral exploration.

Baker, Andrew K. M. January 2007 (has links)
Title page, contents and abstract only. The complete thesis in print form is available from the University of Adelaide Library. / "Inland acidic sulfate soils under fresh water conditions where contemporary clearning of native vegetation has caused erosion, rising of local water tables and excess discharge of saline-sulfatic groundwater. A new systematic and interactive web-based approach was used to improve acquisition, collation, integration and communication of diverse soil-regolith data ... Successful application of the interactive web-based data site, as part of this study, resulted in its uptake as a standard tool for coordinating and reporting on a number of current and future national and international soil-regolith studies." -- from Abstract. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1289208 / Thesis (Ph.D.) -- University of Adelaide, School of Earth and Enviromental Sciences, 2007
