Multi-beam echosounder data and grain size analysis data of surface sediment were acquired and analyzed in order to investigate the shelf-to-slope morphology, geological character, and their geological controlling factors in the southwestern margin of the Ulleung Basin. According to the morphologica...

대륙주변부는 어떤 지역인가? | 대륙주변부(Continental margin)는 연안으로부터 대륙붕, 대륙사면, 대륙대까지 이어지는 육지와 바다의 연계 지역이라 할 수 있다(Bates and Jackson, 1980). 일반적으로 이 지역은 해수면 변동, 폭풍, 지진, 해류, 혹은 조류 등 다양한 해양지질학적 작용에 의하여 육지로부터 공급된 퇴적물이 넓은 면적에 걸쳐 이동, 집적, 침식되는 매우 역동적인 환경이다(Seibold and Berger, 1996). | |
대륙주변부 환경적 특징은? | 대륙주변부(Continental margin)는 연안으로부터 대륙붕, 대륙사면, 대륙대까지 이어지는 육지와 바다의 연계 지역이라 할 수 있다(Bates and Jackson, 1980). 일반적으로 이 지역은 해수면 변동, 폭풍, 지진, 해류, 혹은 조류 등 다양한 해양지질학적 작용에 의하여 육지로부터 공급된 퇴적물이 넓은 면적에 걸쳐 이동, 집적, 침식되는 매우 역동적인 환경이다(Seibold and Berger, 1996). 20세기 중반 이후 발전된 해양 탐사기술과 대륙붕 석유가스전 개발, 수중 무기체계 운용의 증가로 대륙주변부의 현생 해저 퇴적물 분포 특성은 물론 해저면 하부 고기 퇴적층에 관한 지질학적 연구가 전 세계적으로 매우 활발히 진행되어 왔다(Philip et al. | |
울릉분지는 대마도를 경계로 어떤 해류의 영향을 받는가? | 울릉분지는 대마도를 경계로 대마난류(Tsushima Warm Current, TWC)와 동한난류(East Korean Warm Current, EKWC)로 분기되는 쿠로시오 난류의 영향을 받는다(Fig. 1). |
