Abstract

This study was performed to characterize the seasonal variation of water quality and sediment environment from May, 2007 to February, 2008 in 20 stations of Kamak bay. $4.83\sim11.07mg/L$ on surface and $4.70\sim11.19mg/L$ on bottom in DO, $0.16\sim2.03mg/L$ on surface and $0.10\sim1.55mg/L$ on bottom in COD, $0\sim3.04{\mu}g$-at/L on surface and $0\sim15.21{\mu}g$-at/L on bottom in DIN, $0\sim3.04{\mu}g$-at/L on surface and $0\sim2.01{\mu}g$-at/L on bottom in DIP. IN sediment the ranges were 3.80 to 9.78% in IL, $0\sim5.37mg/g$-dry in AVS and $3.09\sim41.01mg/g$-dry in COD.

가막만 해양수질 및 저질의 계절적 변동에 관한 조사를 위해 2007년 5월부터 2008년 2월까지 가막만의 20개 정점을 선정하여 계절별로 관측하였다. 용존산소(DO)는 표층에서$4.83\sim11.07mg/L$와 저층에서 $4.70\sim11.19mg/L$, 화학적 산소요구량은(COD)은 표층에서 $0.16\sim2.03mg/L$와 저층에서 $0.10\sim1.55mg/L$, 용존무기질소는 표층에서 $0.01\sim22.06{\mu}g$-at/L와 저층에서 $0\sim15.21{\mu}g$-at/L, 용존무기인(DIP)은 표층에서 $0\sim3.04{\mu}g$-at/L와 저층에서 $0\sim2.01{\mu}g$-at/L의 농도를 보였다. 퇴적물에서의 강열감량은(IL)은 $3.80\sim9.78%$, 산 휘발성 황화물은(AVS)은 $0\sim5.37mg/g$-dry 그리고 화학적 산소요구량(COD)은 $3.09\sim41.01mg/g$-dry의 농도분포를 보였다.
