Thirteenth International Conference on Climate Change: Impacts & Responses

Abstract

Some of the marine macrofossils isotopic data preserves a signal that suggest early-stage diagenesis, and glacial lake water with δ18O values within previously described similar values. Computer Analysis of Diffraction Data and Multi-Taper Method as a modern technique supports the concept that assessing the diagenetic alteration of macrofossils accurately diatom fossils and sediment geochemistry to investigate human effects on the lakes over the last centuries. However, the method could be used to evaluate the utility of diatom fossil for palaeoenvironmental interpretation from a wide range of geological settings. The sediment fabric formation and diagenetic processes petrography and isotope results infer that the environment of diagenesis and the oxygen isotope values can provide crucial information for interpreting compositional records and their regional and palaeoclimatic significance. The seasonal deposition model is used to reconstruct multidecadal time series from each core, which will be subjected to multi-taper method spectral analysis to determine any significant periodicities occurring within the records[1]. The seasonal deposition model is used to reconstruct multidecadal time series from each core, which will be subject to multi-taper method spectral analysis to determine any significant periodicities occurring within the records. Finally, the diatom lamina thickness analysis is compared to the records of biomarker concentration and investigate the potential utility of this technique to reconstruct past sea ice conditions at ultra-high-resolution.
