We present a new multiproxy data set obtained from IODP core site U1417 (56.9598N, -147.109W, water depth -4187.5m) in the Gulf of Alaska. The sediments were collected during IODP Expedition 341 (Jaeger et al., 2014) and were analysed to reconstruct sea surface conditions by means of alkenone and IR...
