Scattered seashells were observed on the seabed with no marine corals. The baseline studies indicate that biodiversity decreased from the northeast to southwest direction. The dominant groups of phytoplankton were diatoms followed by dinoflagellates, with insignificant vertical variations in species composition and population due to shallow water. The benthic diversity over the majority of the study area was relatively low compared with other nearshore areas in the region. All subtidal habitats showed evidence of disturbance to varying degrees, with no fish species recorded at these locations. The soft sediment habitat was found to cover much of the area footprint, and faunal diversity was very low. Fish diversity and abundance were equally poor with only a few demersal species recorded. No evidence of coral colonization was recorded although the presence of a low-profile, encrusting species was recorded in close proximity, to the east of the study area. Mangrove, coral, and seagrass were absent in the study area and its immediate vicinity. Modelling of waste plume suggested that the harbor water is fairly well-mixed, and the dispersion of ammonia attenuates with distance.

阿拉伯联合酋长国迪拜杰贝阿里的基线海洋调查和养鱼活动对海洋环境的影响。

在没有海洋珊瑚的海床上观察到散落的贝壳。基线研究表明,生物多样性从东北向西南方向减少。浮游植物的主要群体是硅藻,其次是鞭毛藻,由于浅水,物种组成和种群的垂直变化不明显。与该区域其他近岸区域相比,大部分研究区域的底栖生物多样性相对较低。所有潮下栖息地均显示出不同程度的扰动迹象,在这些位置没有鱼类记录。发现软的沉积物栖息地覆盖了该地区的大部分面积,动物群的多样性非常低。鱼类的多样性和丰度同样很差,仅记录了一些沉水物种。尽管在研究区域的东部附近有一个低矮的,包裹的物种的存在,但没有记录到珊瑚定殖的证据。研究区域及其附近没有红树林,珊瑚和海草。废物羽流的模型表明,港口水混合得很好,氨的扩散随距离而减弱。
