Abstract
To study the characters of surface sediment and to describe the seasonal depositional environment as a result of sedimentation process off Byun-San Peninsula, a total 61 samples of surface sediment (32 samples in summer; 29 samples in winter) were collected and analysed. A digitized depth data from sea chart and echosounding profiles along five trans-sections were helpful for understanding the morphological factors. The types classified by the characters of surface sediment are type I (sand, S), type II (silty sand, zS), and type ill (sandy silt, sZ). Mean grain size varies from 2.11 to 7.81
한반도 서해 중부 변산반도 연근해 표층 퇴적물의 퇴적작용 해저지형, 계절별 변화 등을 포함한 퇴적 환경을 연구하기 위해 여름 32 개, 겨울 29 개 표층 퇴적물을 채취하여 분석하였다. 지형적인 특성을 이해하기 위해 해도의 수심자료를 계수화했으며 음향측심기를 이용하여 동서방향을 따라 5 개 선상의 수심단면도를 얻었다. 표층 퇴적물의 퇴적상은 크게 모래(S), 사질니(sZ), 니질사(zS)로 나뉜다. 평균입도는 2.11~7.81
