摘要

摘要: 对2010年夏季采自白令海的颗粒有机物(POM)碳、氮稳定同位素组成进行了分析.结果表明,白令海陆架区和陆坡区的颗粒有机碳(POC)和颗粒氮(PN)含量比海盆区来得高,且陆坡区和海盆区的POC和PN含量呈现随着深度增加而降低的趋势,证明生物过程在调控白令海POM的分布上起着重要作用.与阿拉斯加河流颗粒有机物相比,研究海域颗粒有机物的C/N比值较低,且碳、氮同位素组成较重,证实白令海的颗粒有机物主要来自海洋生源的贡献.在海盆区,颗粒有机物的δ¹³C和δ¹⁵值均随着深度的增加而增加,表明颗粒有机物自表层沉降至深层的过程中,含有较轻碳、氮同位素组成的有机组分被优先降解.与海盆区不同的是,陆架区近底层颗粒有机物的δ¹³C和δ¹⁵值也较高,但可能是沉积物再悬浮的影响所致.

Abstract: Stable carbon and nitrogen isotopic composition of particulate organic matter (POM) were measured for samples collected from the Bering Sea in 2010 summer. Particulate organic carbon (POC) and particulate nitrogen (PN) showed high concentrations in the shelf and slope regions and decreased with depth in the slope and basin, indicating that biological processes play an important role on POM distribution. The low C/N ratio and heavy isotopic composition of POM, compared to those from the Alaska River, suggested a predominant contribution of marine biogenic organic matter in the Bering Sea. The fact that δ¹³C and δ¹⁵N generally increased with depth in the Bering Sea basin demonstrated that organic components with light carbon or nitrogen were decomposed preferentially during their transport to deep water. However, the high δ¹⁵³C and δ¹⁵N observed in shelf bottom water were mostly resulted from sediment resuspension.
