Relationship between Dissolved Oxygen and Chlorophyll a Concentrations at Bang Pa Kong Estuary, Thailand
Abstract
The study of relationship between dissolved oxygen (DO) and chlorophyll a concentration of Bang Pa Kong Estuary were conducted between April and November 2016, including dry season, rainy season and late rainy season. Water samplings were collected from 11 stations (BK1-BK11) using the multiparameter water quality profiler (AAQ-RINKO). Depth profiles of water quality factors were recorded. Result showed that seasonal variation significantly (p < 0.01) influenced water quality factors.The important parameters, i.e., dissolved oxygen concentration and chlorophyll a (Chl-a) concentration were acceptable according to the Marine Water Quality Standard (MWQ) for Aquaculture zone (Type 4). However, oxygen levels detected at the bottom zone in some seasons did not meet MWQ standard. This study also indicated a positive correlation between DO and Chl-a concentration (Pearson correlation coefficient, R = 0.68; p > 0.05) that decreases with depth.
