Environmental mechanisms associated with fish kill in a semi-enclosed water body: An integrated numerical modeling approach.

Fish kill incidents are causing increasing concern to coastal communities globally due to the associated economical, commercial and social impacts. In the Arabian/Persian Gulf, human activities have accelerated to meet the rising demands and the economical ambitions, and are associated with organic and inorganic waste loads linked to algal blooms and fish kills in the receiving environment. Understanding the environmental circumstances associated with these events is crucial for planning and coastal management.

Three-dimensional numerical modelling of transport, fate and distribution of microplastics in the northwestern Arabian/Persian Gulf.

Marine plastic litter has been a major concern over the past decade particularly in semi-enclosed seas such as the Arabian/Persian Gulf, which are likely to impose a relatively higher threat to ecosystem and human health. In this work, we have focused our efforts on the transport features of marine surface microplastics (MPs) in the Gulf. The assessment utilizes a 3D hydrodynamic model of the northern Gulf which was coupled with a particle tracking model.
