Redox variations and bioproductivity in the Ediacaran: Evidence from inorganic and organic geochemistry of the Corumba Group, Brazil

Stable isotope ratios combined with elemental compositions and molecular biomass data provide a powerful tool in Neoproterozoic palaeoenvironmental interpretations. Here, we report the results of an extensive organic and inorganic geochemical study perform ...

Variations of air content in Dasuopu ice core from AD 1570-1927 and implications fore climate change

Jérôme Chappellaz

In relation to Arctic warming, the possible occurrence of methane hydrate degassing events has attracted an increasing interest in recent years. We evaluate the atmospheric impact of rapid and massive emissions of methane and how they are imprinted in ice ...

Fourier spectra of radially periodic images with a non-symmetric radial period

Isaac Amidror

It has been previously shown that a radially periodic image having a symmetric radial period can be decomposed into a circular Fourier series of circular cosine functions with radial frequencies of f=1/T, 2/T, ..., and that its Fourier spectrum consists of ...
