The increase in household and industrial waste into coastal waters is causing the frequent outbreak of "Red Tides" and oxygen deficient water mass. Presently, there are some measures that can be taken to counter eutrophication and protect the enclosed seas of the world from "Red Tides" and oxygen deficient water mass, through the reduction of nitrogen and phosphorous loads from land and coastal regions. However, we must understand the characteristics of each bay's transport of nutrients, before we can decide on the most beneficial measure to implement.
