Phytoplankton distribution and dispersal simulation in Kuantan port during northeast and southwest monsoon season with emphasis on harmful algal bloom /
Harmful algal bloom (HAB) is a proliferation of phytoplankton that can cause harm to the environment and the organisms associated with it, with certain species capable of producing biotoxins which are hazardous to human health.

| 520 | |a Harmful algal bloom (HAB) is a proliferation of phytoplankton that can cause harm to the environment and the organisms associated with it, with certain species capable of producing biotoxins which are hazardous to human health. The first case of HAB in Kuantan Port was recorded on November 2013, followed by another outbreak on August 2014. This study aims to investigate the phytoplankton distribution and dispersal in Kuantan Port during the Northeast and Southwest monsoon season in order to identify how far the HAB can spread in case such an event would ever occur again. Phytoplankton samples were taken at Kuantan Port during Northeast and Southwest monsoon season from three levels of depth (surface, middle, and bottom) from every hour during a period of 24 hours. Phytoplankton samples were preserved in Lugol's Iodine. Physico-chemical properties such as temperature, salinity, pH, dissolved oxygen, total suspended solid (TSS), and nutrient concentration (phosphorus, nitrate, nitrite, ammonia) were also measured. Phytoplankton samples were identified and counted up to genus level. Simulation of phytoplankton dispersal in Kuantan Port was conducted using MIKE 21 FM. A total of fifty one genera of phytoplankton were identified in this study. Average phytoplankton abundance was 309±64 cells/L for Northeast monsoon, and 140±46 cells/L for Southwest monsoon. The average amount of phosphorus, nitrate, nitrite and ammonia recorded during Northeast monsoon was found to be 0.76±1.00 mg/L, 1.66±0.37 mg/L, 0.006±0.001 mg/L, and 0.09±0.02 mg/L respectively, while during the Southwest monsoon sampling was found to be 0.13±0.05 mg/L, 1.31±0.32 mg/L, 0.005±0.002 mg/L, and 0.10±0.02 mg/L respectively Phytoplankton abundance, phosphorus, nitrate, nitrite, TSS and chlorophyll-a were significantly higher during Northeast monsoon. Simulation result showed that HAB that occurs inside Kuantan Port will not be spread out to the open ocean and will remain inside the port. This study also recorded the presence of several HAB species such as Alexandrium sp, Noctilluca sp, and Dinophysis sp. HAB individuals were found to be in low quantity, but could still potentially cause a bloom if the environmental conditions are optimal. The presence of these species further indicates that several safety measures need to be considered to safeguard public health, particularly in Pahang coastal waters. | ||
