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....

These water column data files were collected in Monterey Canyon as part of the Monterey Canyon Coordinated Canyon Experiment (CCE).

Each instrument was in place for deployments lasting up to six months beginning in October 2015 and October 2016. One AMT was placed at 300 meters water depth...

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...
