Australian shelf sediments reveal shifts in Miocene Southern Hemisphere westerlies
Global climate underwent a major reorganization when the Antarctic ice sheet expanded ~14 million years ago (Ma) (1). This event affected global atmospheric circulation, including the strength and position of the westerlies and the Intertropical Convergence Zone (ITCZ), and, therefore, precipitation patterns (2-5). We present new shallow-marine sediment records from the continental shelf of Aus...
متن کاملTRACE ELEMENT STUDY ON THE MIXED CARBONATE-PYROCLASTIC SEDIMENTS (LOWER MIOCENE, CENTRAL BASIN, IRAN)
Geochemical investigations have permitted the refinement of the environmental interpretation of the f-Member of the Qum formation, Central Basin, Iran, which has been established through detailed microfacies (MF) analysis. The analysis revealed that the f-Member carbonates consist of eight distinct microfacies designated by the letters A through H. On the basis of petrographic characteristi...
متن کاملPaleomagnetic and paleoenvironmental implications of magnetofossil occurrences in late Miocene marine sediments from the Guadalquivir Basin, SW Spain
Although recent studies have revealed more widespread occurrences of magnetofossils in pre-Quaternary sediments than have been previously reported, their significance for paleomagnetic and paleoenvironmental studies is not fully understood. We present a paleo- and rock-magnetic study of late Miocene marine sediments recovered from the Guadalquivir Basin (SW Spain). Well-defined paleomagnetic di...
متن کاملMetagenomics of Bacteriophages Isolated from Marine Sediments
Results: The modified method for bacteriophages isolation and purification developed in this work resulted in high concentration of viral particles, which was confirmed by electron and fluorescent microscopy. Some phages were observed to have unusually long tails, up to 1 μm in length. It is possible that this is the result of high concentrations of EPS (the main component of bacterial biofilm)...
متن کاملDiscrete Scattering in Marine Sediments
Testing various models and mechanisms of high frequency seabed scattering was one of primary goals of recent major experiments in sediment acoustics, SAX99 and SAX04, conducted near Ft. Walton Beach, Florida [1-4]. The models to test were based on various assumptions about dominance of certain scattering mechanisms and corresponding theories of scattering. Such models, confirmed by experiments,...
