    TEMPORAL AND SPATIAL VARIATIONS OF NUTRIENTS AND DISSOLVED GREENHOUSE GASES CONCENTRATIONS IN KENYIR LAKE, MALAYSIA
    (UNIVERSITI MALAYSIA TERENGGANU, 2021-10) SITI FARHAIN BINTI MOHD LUDIN
    Freshwater lakes represent significant sources of greenhouse gas emissions, largely influenced by nutrient enrichment within the water column. This study evaluates the dynamic of dissolved carbon dioxide (CO2) and methane (CH4) distribution patterns in Kenyir Lake, aiming for a better understanding of the physical processes controlling internal loading of CO2, CH4, and nutrients in one of the largest freshwater lakes in Malaysia. The distribution of CO2, CH4, nutrients, and physicochemical parameters in the water column of Lake Kenyir was determined from November 2017 to November 2018. During this period, water samples were collected at different depths to measure CO2 and CH4 using headspace gas chromatography, nutrients using the colorimetric method, and basic water quality parameters using a portable water quality meter.
