الوصف: Foraminifera collected from sediment traps deployed at two depths in the Kao-ping submarine canyon were analyzed to provide information on biogenic particle transport. The discovery of benthic foraminiferal shells in the collecting cups was unexpected because the sediment traps were deployed at levels of 54 and 104 m above the seafloor of 290 m depth. The presence of shelf-originated benthic foraminifera captured by the sediment traps suggests that the canyon is not only a conduit for delivering terrestrial materials into the ocean but also acts as a passage allowing particles of marine-origin to be transported toward the shore. Furthermore, during the passing of Typhoon Kai-Tak, the cups at both upper and lower levels collected a higher diversity of benthic foraminifera species than at other time intervals, while there was also an increased similarity in the species collected by all cups. Most of the benthic taxa found in collecting cups were also present at as forms living in surface sediments from the shelf and slope as determined by staining, supporting a shore-wards transport particles of marine origin in the submarine canyon. Nevertheless, the stable isotopic compositions of the benthic foraminifera Cibicides wuellerstorfi displayed a similar range of variation as the other planktonic foraminifera (Globigerina bulloides, Globigerinoides sacculifer and G. ruber), indicating these species dwelled at a relatively shallow depth (o50 m).
