연구의 목적 및 내용
낙동강 하구 지역의 시추코아 퇴적물의 다양한 고기후 분석 자료를 이용하여 마지막 빙하기 이후 동해로 유입되기 시작한 대마난류의 발달과 영향이 한반도 기후변화와 어떤 관계를 보이는 지를 규명

연구개발성과
- 낙동강 삼각주의 층서는 상부 모래층(10-15 m, <1 ka), 중간 머드층(~20 m, 1-9 ka), 하부 모래층(6-9 m, ~9 ka)과 하부 머드층(10-15 m, 9-12 ka)으로 구성됨
- 홀로세 동안 해수면 상승에 의해 중간 머드층은 탄산염, P/T 비율, 총유기탄소와 총질소량의 증가를 보이며, 8-7 ka 시기의 δ¹³C_org 값을 통해 대마난류의 영향이 극대화 되었음
- 저서성 유공충의 군집분석에 의한 4개의 군집구성(A, B, C 그리고 D)은 낙동강 삼각주는 육상과 해양 쪽의 환경적 차이를 보여줌
- 저서성 유공충의 시공간적 군집분포에 의해 8-7 ka 동안에는 육상방향으로 해수의 유입이 강화된 대마난류와 더불어 해수면의 상승으로 낙동강 삼각주 안쪽까지 발생됨
- 8-7 ka 시기 대마난류의 강화는 Quercus zone에서 Alnus-Quercus-Pinus zone으로 화분의 구성이 변화하는 한국의 홀로세 육상기후에 영향을 미친 것으로 해석됨

Abstract ▼

Purpose & Contents
Based on paleoclimate multiproxy of drilled sediments at the Nakdong River estuary, the climate change in Korean Peninsula will be reconstructed in term of the effect and development of Tsushima Warm Current that flows into the East Sea since the Last Glacial Maximum

Results
- The stratigraphic lithologic successions of the Nakdong River delta consists of a upper sand unit (10–15m thick and <1 ka), a middle mud unit (~20 m thick and 1–9 ka), a lower sand unit (6–9 m thick and ~9 ka), and a lower mud unit (10–15 m thick and 9–12 ka).
- During the Holocene sea level rise, the middle mud unit is characterized by distinct peaks in CaCO₃ content, P/T ratios, total organic carbon and total nitrogen contents, and δ¹³C_org values at 7–8 ka, attributed to the greatest influence of the Tsushima Warm Current.
- Based on cluster analysis of the Nakdong River delta, four sample clusters (A, B, C, and D) were recognized the landward–seaward gradient of environmental conditions.
- The maximum landward expansion of benthic foraminifera within the delta was probably caused by the intensified Tsushima Warm Current in addition to the sea-level rise during the early to middle Holocene
- The strongest marine forcing by the TWC at 7~8 ka corresponds to the terrestrial paleoclimate change in Korea when the pollen zonation changed from the Quercus zone to the Alnus-Quercus-Pinus zone.
- Research achievement of publications
