Living benthic foraminiferal assemblages in surface samples of the Arabian Sea@en

The distribution, biomass, and diversity of living (Rose Bengal stained) deep-sea benthic foraminifera (>30 µm) were investigated with multicorer samples from seven stations in the Arabian Sea during the intermonsoonal periods in March and in September/October, 1995. Water depths of the stations ranged between 1916 and 4425 m. The distribution of benthic foraminifera was compared with dissolved oxygen, % organic carbon, % calcium carbonate, ammonium, % silica, chloroplastic pigment equivalents, sand content, pore water content of the sediment, and organic carbon flux to explain the foraminiferal patterns and depositional environments. […]1995年3月及9月至10月的季风间歇期，研究者于阿拉伯海7个站位采用多管取样器（multicorer）采集沉积物样品，对粒径大于30 μm的经玫瑰红（Rose Bengal）染色的活体深海底栖有孔虫（deep-sea benthic foraminifera）的分布、生物量与多样性展开了调查。各站位的水深介于1916米至4425米之间。为阐明底栖有孔虫的分布格局与沉积环境，研究将该类有孔虫的分布数据与溶解氧、有机碳占比、碳酸钙占比、铵盐、二氧化硅占比、叶绿体色素当量值、砂粒含量、沉积物孔隙水含量以及有机碳通量等环境参数进行了对比分析。[…]
