In this project, 15 sites have selected for the greenhouse gases (GHGs) and nutrient<br />

measurement which carry out on November 2017 as wet season and March 2018 as<br />

dry season along the Terengganu Estuary. 45 samples which collect from 3 difference<br />

depths at each site were measured for nutrients and greenhouse gases concentration.<br />

The dissolve oxygen (DO) during dry season ranged from 5.92-7.61mg/L which is<br />

higher than wet season 4.29-5.19mg/L. Average nutrient concentration during dry<br />

season is lower than wet season, for example ammonia concentration during dry<br />

season is 0.06ppm, while wet season is 0.11ppm. For GHGs, average carbon dioxide<br />

concentration is higher during dry season (5510ppm) compare to wet season<br />

(542ppm); while average methane concentration during dry season (31ppm) is lower<br />

than wet season (182ppm).<br />
