137cs dating sediment
After establishing the lithologic and lithodemic framework of an area, Dr.Blake concentrates on such topics as the microscale to macroscale analyses of structural and metamorphic fabric elements, the mechanical control that fabric exerts on deformation, progressive plastic-brittle deformation, overprinting relationships, and metamorphism during fault zone development, and plate tectonic interactions responsible for terrane accretion. Doug Gamble is an applied climatologist with interests in hydrology, climate variability, and coastal and island environments of the Caribbean and the southeastern United States.This suggestion for the Holocene–Anthropocene boundary may ultimately be superseded, as the Anthropocene is only in its early phases, but it should remain practical and effective for use by at least the current generation of scientists. Benedetti is a physical geographer with interests in geomorphology, Quaternary science, and geoarchaeology.His current research topics include late-Holocene environmental (climate, vegetation, disturbance regimes, etc.) change in Central America, the circum-Caribbean, and North Carolina, tracking prehistoric maize cultivation using stable isotope analyses of lake sediments, assessing the impacts of rapid climate change on prehistoric human populations, and assessing the impacts of global climate change on carbon cycling in boreal soils. Lane has also been lucky enough to conduct much of his research in beautiful locations such as Costa Rica, the Dominican Republic, Mexico, Newfoundland (Canada), and St. Current projects include the taxonomy of benthic marine diatoms, the impacts on benthic diatom floras of salt marsh renourishment through emplacement of dredge spoil in degrading marshes, and sediment stabilization by diatoms and sediment resuspension in intertidal habitats. Her research focuses on sediment transport mechanisms in coastal environments ranging from tidal creeks and inlets, to large estuaries and the continental shelf. Her research answers questions related to the sources, cycling, and transport of organic matter and nutrients in aquatic (marine, estuarine and riverine) environments.
Please discuss your proposal with the appropriate ANSTO Contact Scientist before submitting your proposal as they will assist you in making the correct capability selection.
However the method is destructive and other radionuclides such as Pb dating can be undertaken by gamma spectrometry technique.
30-50g of dried sample is required for analysis using a standard gamma spectrometer or 5g using a Well detector.
His research investigates geomorphic responses to natural and anthropogenic environmental change.
His recent projects have focused on late Quaternary sea level and climate change, landscape change in archaeological settings, and the influence of floods on sediment transport in large rivers [email protected]
