Modern techniques for detrital mineral provenance were applied to sediment core 96/12-1pc from the Lomonosov Ridge in the central Arctic Ocean. The techniques include quantitative clay mineralogy analysis combined with determination of Nd, Pb, and Sr

Ice-rafted quartz sand grains of sediment samples representing marine isotope stages (MIS) 3 and 4 from the Lomonosov Ridge, Arctic Ocean, are here analysed with a scanning electron microscope (SEM) to characterise processes in the sediment source ar

Ice-rafted grains of the central Arctic Ocean sediments provide a reliable proxy for Arctic palaeoenvironments and climatic conditions that prevailed at the time of their deposition. To understand ice involvement and implications for environmental ad

During the entire Quaternary, ice sheets advanced and retreated across the circum-Arctic margins in a series of climate related glacial-interglacial cycles. It is critical to obtain evaluation of the nature of initiated glaciers at the Arctic margins
