Current and productivity patterns in the equatorial Pacific across the last glacial maxium based on radiolarian east-west and downcore faunal gradients
Radiolarians were studied in 11 box-cores retrieved in the western (160°E), central (135°W) and eastern (90°W) equatorial Pacific. The western and central cores span the last ca. 40 000 yrs, while the eatern core is estimated to reach approx. 12 000-17 000 yrs. Time-average data show very sharp asse...

| 520 | 3 | |a Radiolarians were studied in 11 box-cores retrieved in the western (160°E), central (135°W) and eastern (90°W) equatorial Pacific. The western and central cores span the last ca. 40 000 yrs, while the eatern core is estimated to reach approx. 12 000-17 000 yrs. Time-average data show very sharp assemblage composition difference between the three locales. Species dominant at the western most sites are indicative of warm, oligotrophic conditions; than atocoenoses from 135°W suggest strong input of California Current radiolarians; while the easternmost core hosts assemblages which point to a significant influence of the Peru Current. In the central and eastern parts of the equatorial Pacific belt, radiolarian distributional patterns in the sediments and their shifts during the last millennia respond chiefly to environmental conditions at depths in excess of 50 m (rather than to sea surface temperature), and to subsurface and deep lateral advection of shells from eastern boundary current areas. -from Author |l eng | |
