| contents | By means of a multiproxy data set combining biomarker (alkenones, n-alkanes), microfossil (diatoms) and sedimentological (ice rafted debris, XRF) data obtained from sediments from IODP Site U1417 in the Gulf of Alaska, we elucidate the paleoenvironmental setting in this area during the Mid Pleistocene Transition. The data point to a stimulation of the marine primary productivity through the input of nutrients (e.g. iron) via aeolian dust and icebergs. These fertilization pulses were likely triggered by the dynamic behaviour of the Cordilleran Ice Sheet during the Pleistocene. |
