During expedition 202 of research vessel SONNE in 2009, 39 sea-floor surface sediments were sampled over a wide area across the North Pacific and the Bering Sea, which are well suited as reference archives of modern environmental processes. In this study, we used the samples to infer the documentation of land-ocean linkages of terrigenous sediment supply. We followed an integrated approach of grain-size analysis, bulk mineralogy, and clay mineralogy in combination with statistical data evaluation (end-member modelling of grain-size data, fuzzy-cluster analysis of mineralogical data), in order to identify the significant sources and modes of sediment transport in an overregional context. We also compiled literature data on clay mineralogy and updated those with the new data. Today, two processes of terrigenous sediment supply prevail in the study area: far-distant aeolian sediment supply to the pelagic North Pacific as well as hemipelagic sediment dispersal from nearby land sources by ocean currents along the ... : Supplement to: Wang, Rong; Biskaborn, Boris K; Ramisch, Arne; Ren, Jian; Zhang, Yongzhan; Gersonde, Rainer; Diekmann, Bernhard (2016): Modern modes of provenance and dispersal of terrigenous sediments in the North Pacific and the Bering Sea: Implications and perspectives for palaeoenvironmental reconstructions.
