Environmental magnetic records of mid-late Pleistocene drift sedimentary sequences from the Antarctic Peninsula, Pacific margin
Summary The Pacific Continental Margin of the Antarctic Peninsula was the area of interest of the Sediment Drift of The Antarctic Offshore Project (SEDANO Project). A paleomagnetic and environmental study was carried out on four Pleistocene sequences from Drift 7. High resolution measurements were p...
