There have been many studies on iron as a limiting nutrient for productivity in the World Ocean, but only a few studies have been done in the Arabian Sea on iron limitation. Sensitivity of primary productivity, chlorophyll, nitrate, pCO₂ and carbon flux in the Arabian Sea to one of the parameters related to iron limitation has been investigated using a three-dimensional coupled biogeochemical model (TOPAZ) embedded in Modular Ocean Model (MOM) in the global domain, for climatology and interannual variability. Initially, the model results are evaluated for many of the biogeochemical components using data from World Ocean Atlas, satellites and cruises in the Arabian Sea. It is noticed that model results capture spatial and temporal variations of some of the biogeochemical components and fluxes in the north Indian Ocean. Subsequently, it is shown that micronutrient iron plays a significant role on the growth of phytoplankton, utilization of nutrients, pCO₂ in the ocean and carbon flux across the air–sea interface in north and north-west regions of the Arabian Sea.

在世界海洋中，已经有许多关于铁作为限制生产力的养分的研究，但是在阿拉伯海，关于铁的限制只有很少的研究。初级生产力，叶绿素，硝酸盐，pCO _2的敏感性在全球范围内，使用嵌入在模块化海洋模型（MOM）中的三维耦合生物地球化学模型（TOPAZ），研究了阿拉伯海中与铁限制相关的参数之一的碳通量，以了解气候和年际变化。最初，使用来自世界海洋图集，卫星和阿拉伯海航行的数据对许多生物地球化学成分的模型结果进行了评估。注意到模型结果捕获了北印度洋某些生物地球化学成分和通量的时空变化。随后，研究表明微量元素铁在浮游植物的生长，营养物质的利用，pCO ₂方面起着重要作用。 在阿拉伯海的北部和西北部区域，海洋中的碳通量和跨海-海界面的碳通量。
