Abstract

Geochemical approaches on the two recovered piston cores were performed to understand the characteristics of organic matters and the influence of the sea level variation of the East Sea in the Hupo Basin since the Holocene. The analyzing results on organic components (TOC and TN), and isotopic compositions of organic matters showed the variation to core locations and sampling depths. In core 08HZP-01, their values were gradually changed with depth from 4 mbsf to seafloor. However, rapid variation was observed at the boundary of 4.71 mbsf (meter below seafloor) in core 08HZP-03. Based on TOC/TN, $\delta^{13}C_{org}$ and $\delta^{15}N_{org}$, the origin of organic matters in the Hupo Basin can be divided into three groups; 1) predominant marine algae, 2) $C_3$ land plant, and 3) mixture of $C_3$ land plant and marine/freshwater algae. It is likely that the vertical and spatial variations of organic and isotopic compositions reflect the shifts in sedimentary environment (including sediment transportation) by ocean currents and sea-level changes and others during the Holocene period.

동해안의 후포분지에서 채취한 두 개의 피스톤 코어를 이용하여 후포분지에서의 홀로세 퇴적물 내 유기물의 특징 및 동해 해수면 변화와의 관계를 규명하고자 지화학적 접근을 시도하였다. 채취한 시료에 대한 유기물 성분 분석(TOC와 TN)과 유기물 동위원소($\delta^{13}C_{org}$$\delta^{15}N_{org}$) 분석 결과들은 코어와 시료 채취 심도에 따라 분석값들이 특징적으로 변화한다. 코어 08HZP-01에서는 4 mbsf(meter below seafloor)에서 코어 표면까지 비교적 채취 심도가 상부로 갈수록 지화학 분석값들이 점이적으로 증가하지만, 코어 08HZP-03에서는 4.71 mbsf를 기준으로 상부와 하부에서 급격한 지화학 분석값들의 변화가 발생한다. 유기물의 TOC/TN과 $\delta^{13}C_{org}$$\delta^{15}N_{org}$의 값을 종합적으로 고려하였을 때, 후포분지의 유기물은 해양 조류 기원이 우세한 집단, $C_3$ 육성 식물 기원이 우세한 집단, 해성/육성 조류와 $C_3$ 육성 식물의 혼합기원이 우세한 집단으로 구분할 수 있다. 이러한 퇴적물 내 유기물의 심도에 따른 특성 및 기원 변화는 주로 홀로세 동해 해류와 해수면 등의 변화에 따른 퇴적환경 변화 (퇴적물 이동 포함)에 기인한 것으로 보인다.
