摘要: Abstract. The Arabian Sea is a region of elevated productivity with the highest globally recorded fluxes particulate organic matter (POM) to deep ocean, providing an abundant food source for fauna at seafloor. However, benthic communities are also strongly influenced by intense oxygen minimum zone (OMZ), which impinges on continental slope from 100 1000 m water depth. We compared trophic ecology foraminifera Oman and Pakistan margins (140–3185 depth). These two contrasting both in terms abundance sedimentary intensity OMZ. Organic carbon concentrations surficial sediments were higher margin (3.32 ± 1.4%) (2.45 1.1%) (SOM) quality estimated Hydrogen Index was (300–400 mg HC TOC−1) (
