광양만에서 탄산염 포화상태의 계절변화

Abstract

In winter, some of the surface and bottom waters were undersaturated with respect to aragonite; the lower aragonite saturation state (&#61527;arag) values (<1.0) were observed at 3 stations at the surface waters and 1 station at the bottom waters. However, the surface and bottom waters were supersaturated with respect to calcite. In spring, some of the surface waters were also undersaturated with respect to aragonite and calcite; the lower &#61527;arag values (<1.0) were observed at 11 stations among 19 stations, and the lower &#61527;cal values (<1.0) were found at 4 stations. At the surface waters, &#61527;arag values were lowest at the mouth of the Seomjin River and increased toward offshore. Surface salinity was significantly reduced to 1.94 at the mouth of the Seomjin River. Heavy precipitation had occurred just before the survey, which might bring large amounts of freshwaters into Kwaungyang Bay through the Seomjin River.tom waters.
