Global prediction of abyssal hill roughness statistics for use in ocean models from digital maps of paleo-spreading rate, paleo-ridge orientation, and sediment thickness
(Elsevier, 2010)
Abyssal hills are the dominant small-scale roughness fabric over much of the ocean floor. Created at midocean
ridges by combined volcanic and tectonic processes, they are rafted away by plate spreading and
modified through ...
Evaluation of Land Snails for Clumped Isotope Paleothermometry: A Case Study of the Pleistocene of Bermuda
(2013-06-19)
With the advent of clumped isotope analyses, sources of data that were previously not of use in determining paleoenvironment may become valuable proxies for the reconstruction of past Earth surface temperatures. Land snails, ...
Variable Hf-Sr-Nd Radiogenic Isotopic Compositions in a Saharan Dust Storm over the Atlantic: Implications for Dust Flux to Oceans, Ice Sheets and the Terrestrial Biosphere
(2013-01-16)
Isotopic characterization of aerosol mineral particles (atmospheric dust) of varying sizes is essential in classifying source areas, and for determining the source of dust deposited over oceans and icesheets. However, the ...
