Distribution of phytoplankton in Kuantan port during northeast monsoon season

Harmful algal bloom (HAB) is a proliferation of phytoplankton that can produce biotoxins and cause harm to human health, as well as the environment and the organisms associated with it. The first case of HAB in Kuantan Port was recorded on November 2013, followed by another outbreak on August 201...

Phytoplankton samples were counted and identified up to genus level. Simulation of phytoplankton dispersal in Kuantan Port was conducted using the program MIKE 21. Thirty-eight taxa of phytoplankton were identified. Phytoplankton concentration ranged from 124 cells/L to 775 cells/L. TSS value ranged from 0.0345 g to 0.0110 g.
