2 Microbial Gene Research & Resources Facility (MGRRF) Institute for Molecular & Cellular Therapies (IMCT) Biomolecular & Biomedical Sciences (BBS) Brisbane The Great Artesian Basin (GAB) is a unique deep subsurface thermal non-volcanic aquifer Worlds largest underground water reserve (1.7 x 10 6 km 2 = 8.7 x m 3 ) 5000 free-flowing bore wells have been drilled thro’ 4 sequential interbeded sedimentary bases of different geological ages– distinct water chemistry. Natural discharge via mound springs (basin edges)
3 Microbial Gene Research & Resources Facility (MGRRF) Institute for Molecular & Cellular Therapies (IMCT) Biomolecular & Biomedical Sciences (BBS) GAB is a “hot bed” for microbial colonisation adaptation of new types of microbes: Heated by the earth’s hot core due to the deep nature of the aquifer- rate of 1 o C/30 m depth < 95 o C at bore source; forms a temperature gradient to ambient along drain runoff channels Aquifer age: 2 million yrs (water) but the sedimentary bases are up to 400 million old pH neutral to 10
