Grain size data for sediment cores collected in the water column of Monterey Canyon, offshore California

Charles Paull, Peter Talling, Katie Maier, Daniel Parsons, Jingping Xu & Kurt Rosenberger
Sediment grain size data from Anderson sediment trap samples collected in Monterey Canyon as part of the Monterey Canyon Coordinated Canyon Experiment (CCE). The CCE was set up to measure the passage of sediment gravity flows down Monterey Canyon. Anderson sediment traps are designed to passively collect particulate material as it settles from the water column into a tube. This effectively provides a record of the sediment and particulate matter passing through the water column....

Detrital zircon U-Pb geochronology of the Oligocene Huagang Formation in the East China Sea Shelf Basin

Wei Wang, Tandis Bidgoli, Xianghua Yang & Jiaren Ye
Researchers have long suspected a source-to-sink link between the Yangtze Block (and/or North China Block) and Eocene-Miocene passive margin strata in Taiwan, and various models have been proposed to explain similarities in provenance and the presence of Archean grains. The East China Sea Shelf Basin (ECSSB), whose evolution has been neglected in most models, resides between potential mainland China source regions and the sediment sink in Taiwan, and occupies the corridor through which sediment would...
