Age and origin of ground water Radiocarbon and tritium analyses provide age-related information about the water from sandstone aquifers in the Sydney Basin assisted water authorities to identify groundwater sources that might be exploited sustainably.Regional and global climate variability Measurement of carbon-14 and stable isotopes in southern hemisphere tree rings, cave structures and corals provided researchers information on variations in atmospheric transport, ocean water circulation and rainfall over the last 15 000 years.Only here you can find hundreds of exclusive live arab sex chat jasmin Indian Adult Xx X Videos Porn Videos Downloads Sex2050 sex2050.com/indian_sex_Oldal lefordítása indian sex clip, indian hindi sex video, hindi pure sex video, download indian sex videos, hindi sex tube, Mp4 Videos Downl live arab sex chat jasmin BOLLYWOOD SEX.Oldal lefordítása A great collection of bollywood hardcore and Indian porn models!

Ocean water circulation ANSTO researchers used radiocarbon dating of coral samples collected in 1836 from the Cocos (Keeling) Islands to gain valuable insights into the upward movement of deep ocean waters in the north-western Indian Ocean.
Continental glacial cycles Researchers have tested for beryllium-10 and aluminium-26 in exposed rocks to date the ebb and flow of alpine glacier systems in the southern hemisphere over the past 100,000 years.
So the greater the concentration of these, the older the rock.
ANSTO is also capable of analysing samples to the lowest levels of radiometric detection and are routinely applied to samples of late Quaternary age (the last 350,000 years).
Older samples in this range are dated using the uranium/thorium disequilibrium method whilst younger samples are dated using the lead-210 dating method.
