Abstract

We determined the influence of Sargassum beds on the water quality in Gamak Bay, Korea. Water temperature and salinity range from 3.3 to $23.4^{\circ}C$ and from 29.6 to 33.7 psu, respectively. Dissolved oxygen was 10.45 mg L-1 in the Sargassum bed and 9.23 mg L-1 in the control. Chlorophyll-a was $3.90{\mu}g\;L^{-1}$ in the Sargassum bed and 2.21${\mu}g \;L^{-1}$ in the control. Chemical oxygen demand were 1.14${\mu}g\;L^{-1}$ in the Sargassum bed and 1.43${\mu}g\;L^{-1}$ in the control. Total nitrogen were 0.038${\mu}g\;L^{-1}$ in the Sargassum bed and 0.067${\mu}g \;L^{-1}$ in the control. Total phosphorus were 0.043${\mu}g \;L^{-1}$ in the Sargassum bed and 0.072${\mu}g \;L^{-1}$ in the control. Multivariate statistical analysis was used to analyze data. Water temperature was highly positively correlated with DO (p<0.01). T-N was highly positively correlated with T-P (p<0.01).
