| Zusammenfassung |
| The ocean’s mesopelagic organisms remineralize most organic export flux and their numbers
respond geographically and temporally to variations of that flux. Few members of this
community leave a fossil record but of those that do Radiolaria are the most abundant and
diverse. The flux of selected deep- and shallow-living radiolarians can be used to measure
biological activity in discrete intervals of the oceans water column. Deep-living (>200m)
species, characterized by high percentages of C. davisiana, dominate late Pleistocene
radiolarian flux in northwest Pacific sediments, while shallow-living ( |
