    Hydrodynamics, nutrient concentrations, and phytoplankton biomass in a shallow and restricted coastal lagoon under different tidal and monsoonal environmental drivers
    (Elsevier, 2020) Zuraini Zainol; Mohd Fadzil Akhir; Samsuri Abdullah
    The influences of environmental forces under different tidal and monsoonal settings on the variability of temperature and salinity, nutrient concentrations, and phytoplankton biomass (chlorophyll-a) in a shallow and narrow Setiu Lagoon were studied during the southwest monsoon, wet period of northeast monsoon, and dry period of northeast monsoon. Vertical profiles of temperature and salinity were measured at 10 stations. Water samples were collected at the surface layer of all stations for the determination of nutrient and chlorophyll-a concentrations.

    Impacts of future sea-level rise under global warming assessed from tide gauge records: A case study of the East Coast Economic Region of Peninsular Malaysia
    (Multidisciplinary Digital Publishing Institute (MDPI), 2021) Milad Bagheri; Zelina Z. Ibrahim; Mohd Fadzil Akhir; Bahareh Oryani; Shahabaldin Rezania; Isabelle D. Wolf; Amin Beiranvand Pour; Wan Izatul Asma Wan Talaat
    The effects of global warming are putting the world’s coasts at risk. Coastal planners need relatively accurate projections of the rate of sea-level rise and its possible consequences, such as extreme sea-level changes, flooding, and coastal erosion. The east coast of Peninsular Malaysia is vulnerable to sea-level change. The purpose of this study is to present an Artificial Neural Network (ANN) model to analyse sea-level change based on observed data of tide gauge, rainfall, sea level pressure, sea surface temperature, and wind.

    Physical characteristics and nutrients status off Pulau Besar, Malacca and Tanjung Tuan, Negeri Sembilan, Malaysia: A preliminary study
    (Universiti Pertanian Malaysia Press, 2019) Zuraini Zainol; Azizi Ali; Mohd Safuan Che Din; Mohd Fadzil Akhir; Zainudin Bachok; Ahmad Ali
    Degradation of coastal water quality is one of the major concern in the Malacca Strait since this area is one of the most important fishing ground in Malaysia. Despite being great in the fishery industry, Malacca and Negeri Sembilan somehow recorded the lowest marine fishes landing, which raises a question about dynamics of this area. It is therefore, a preliminary study of the physical properties and nutrient concentrations carried out from 27 March to 4 April 2016 at the coastal water off the southern west coast of Peninsular Malaysia, specifically at Pulau Besar, Malacca and Tanjung Tuan, Negeri Sembilan. Data for temperature, salinity, and dissolved oxygen (DO) was acquired by using Conductivity, Temperature, and Depth (CTD) probe. Meanwhile, nutrient concentrations determination in this study was done by using a Westco Smartchem 200 Discrete Analyser, according to the procedure adopted from United States Environmental Protection Agency (USEPA).

    Sea-level projections using a NARX-NN model of tide gauge data for the coastal city of Kuala Terengganu in Malaysia
    (Springer, 2023) Milad Bagheri; Zelina Z. Ibrahim; Isabelle D. Wolf; Mohd Fadzil Akhir; Wan Izatul Asma Wan Talaat; Bahareh Oryani
    The impact of global warming presents an increased risk to the world’s shorelines. The Intergovernmental Panel on Climate Change (IPCC) reported that the twenty-first century experienced a severe global mean sea-level rise due to human-induced climate change. Therefore, coastal planners require reasonably accurate estimates of the rate of sea-level rise and the potential impacts, including extreme sea-level changes, floods, and shoreline erosion.

    Short-term observations of beach Morphodynamics during seasonal monsoons: two examples from Kuala Terengganu coast (Malaysia)
    (Springer, 2019) Effi Helmy Ariffin; Mouncef Sedrati; Mohd Fadzil Akhir; Mohamad Noradlan Mohd Norzilah; Rosnan Yaacob; Mohd Lokman Husain
    This paper describes the morphodynamic changes that took place along Kuala Terengganu coastline over daily periods during seasonal monsoons (onset of Northeast Monsoon in October 2014 and during Southwest Monsoon in May 2015). Cross-shore beach profiles had been determined and foreshore sediments were sampled from two selected beaches; north of Kuala Terengganu at Pengkalan Maras (PM) and another to the south at Kuala Ibai (KI).

    Spatial and temporal variability of sea surface temperature during El-Niño Southern Oscillation and Indian Ocean Dipole in the Strait of Malacca and Andaman Sea
    (Elsevier, 2020) Noor Suhadah Isa; Mohd Fadzil Akhir; Poh Heng Kok; Nurul Rabitah Daud; Idham Khalil; Nur Hidayah Roseli
    This study examined the long-term trends and the impacts of climate variability caused by El-Niño Southern/Oscillation (ENSO) and Indian Ocean Dipole (IOD) by using 33-year Advanced Very High Resolution Radiometer (AVHRR) sea surface temperature (SST). The data were retrieved from year 1982 to 2014, hence enabled the observation of both ENSO and IOD events based on this long-term SST trends in the Strait of Malacca (SoM) and Andaman Sea. The 4-km resolution of satellite-derived SST data had been gathered from the National Oceanic and Atmospheric Administration (NOAA)
