This overview compares algal blooms and pelagic fisheries of the Arabian Gulf with the Sea of Oman. The data consist of remotely sensed characteristics, directly sampled and modeled. Elucidated seasonal trends were based on 15-year seasonal means, as well as weekly time series of physical parameters. The environmental characteristics (namely photosynthetically available radiation, atmospheric pressure, temperature, wind, aerosol optical thickness, surface currents, surface temperature, salinity, concentration of dissolved oxygen, nitrates, phosphates, chlorophyll-a, net primary production, phytoplankton, zooplankton biomass, fish larvae abundance, small and large pelagic fish catches) were compared between regions. In Sea of Oman, high concentrations of chlorophyll-a were associated with relatively high concentrations of nitrates and phosphates, as well as kinetic energy of surface currents which exceeded that in Arabian Gulf. The dinoflagellate Noctiluca scintillans is one dominat alga in the Sea of Oman, whereas diatom species are more common in the Arabian Gulf blooms. In general, the phytoplankton and zooplankton species diversity during winter was higher than in summer periods. Catches of small pelagic fish (in particular sardines) in the Sea of Oman exceeded that in the Arabian Gulf. This might be associated, in part, with differences in trophic levels interactions. The turnover rate of the net primary production through zooplankton in Sea of Oman was found to be much higher than in Arabian Gulf waters.

阿拉伯湾和阿曼海远洋生态系统季节性变化的比较

本概览将阿拉伯湾与阿曼海的藻华和远洋渔业进行了比较。数据由遥感特征组成，直接采样和建模。阐明的季节性趋势基于 15 年的季节性平均值，以及每周的物理参数时间序列。环境特征（即光合有效辐射、大气压力、温度、风、气溶胶光学厚度、地表流、地表温度、盐度、溶解氧浓度、硝酸盐、磷酸盐、叶绿素-a、净初级生产、浮游植物、浮游动物生物量、鱼幼虫丰度、小型和大型远洋鱼类捕获量）在区域之间进行了比较。在阿曼海，高浓度的叶绿素 a 与相对高浓度的硝酸盐和磷酸盐有关，以及超过阿拉伯湾的表层流动能。甲藻夜光藻是阿曼海的一种主要藻类，而硅藻物种在阿拉伯湾的水华中更为常见。总体而言，冬季浮游植物和浮游动物物种多样性高于夏季。阿曼海的中上层小鱼（特别是沙丁鱼）的捕获量超过了阿拉伯湾的捕获量。这可能部分与营养级相互作用的差异有关。发现阿曼海通过浮游动物的净初级生产周转率远高于阿拉伯湾水域。而硅藻物种在阿拉伯湾水华中更为常见。总体而言，冬季浮游植物和浮游动物物种多样性高于夏季。阿曼海的中上层小鱼（特别是沙丁鱼）的捕获量超过了阿拉伯湾的捕获量。这可能部分与营养级相互作用的差异有关。发现阿曼海通过浮游动物的净初级生产周转率远高于阿拉伯湾水域。而硅藻物种在阿拉伯湾水华中更为常见。总体而言，冬季浮游植物和浮游动物物种多样性高于夏季。阿曼海的中上层小鱼（特别是沙丁鱼）的捕获量超过了阿拉伯湾的捕获量。这可能部分与营养级相互作用的差异有关。发现阿曼海通过浮游动物的净初级生产周转率远高于阿拉伯湾水域。与营养级相互作用的差异。发现阿曼海通过浮游动物的净初级生产周转率远高于阿拉伯湾水域。与营养级相互作用的差异。发现阿曼海通过浮游动物的净初级生产周转率远高于阿拉伯湾水域。
