| 英文摘要 | Planktic foraminifera-bound organic nitrogen isotopes (FB-delta N-15) archived in sediments provide an opportunity to reveal past changes in marine nitrogen cycling in the upper water column. However, detailed knowledge about living foraminifera FB-delta N-15 is still critically lacking. This study presents the FB-delta N-15 analysis of planktic foraminifera collected from plankton tows and sediment traps in the South China Sea and the Bay of Bengal. Tests of Globigerinoides sacculifer with- and without-sac like chamber from plankton tows showed almost identical FB-delta N-15 values, suggesting that high thermocline delta N-15 is not incorporated into the carbonate tests during gametogenic calcification. Sediment trap samples revealed that species dwelling in the upper euphotic zone, such as Globigerinoides sacculifer, contained slightly depleted FB-delta N-15 relative to the deeper-dwelling species, such as Orbulina universa and Globigerinella siphonifera. The three species also contained FB-delta N-15 similar to delta N-15 of the suspended particulate organic matter at corresponding dwelling depths. Our results confirm the increase in FB-delta N-15 from shallower-dwelling species to deeper-dwelling species and these FB-delta N-15 differences (Delta N-15(vertical)) between shallower- and deeper-dwelling species may shed light on the nitrogen dynamics of the euphotic zone in the South China Sea, which is under the influence of the East Asian winter monsoon. |
