In southwestern East Sea, we investigated the spatio-temporal distribution characteristics of particulate organic carbon (POC) and nitrogen (PON) in September 2011 (summer), January (winter) and May 2012 (spring). Although cold waters known as the origin upwelling in the surface layer of September w...

생물학적 펌프라고 불리는 것은? | 해양의 입자성 유기물질(Particulate Organic Matte; POM) 중 유기탄소의 심층수 침강은 “생물학적 펌프”라고 불리며, 대기 중의 이산화탄소를 생물학적으로 해양에 축적하는 중요한 과정이다(Hara and Koike[2000]). 또한 침강하는 동안 유기입자의 집적을 보이며, 수중과 저서생태계에 잠재적인 먹이 공급원으로 작용하는 등 생태계 내에 에너지를 전달하는 중요한 역할도 수행한다(Deuser and Ross[1980]). | |
동해 남서해역 표층 A line(3개 정점), B line(3개 정점), C line(7개 정점) 및 D line(8개 정점)의 수괴의 특징은 어떠한가? | [2014])의 특성을 가지고 있어, 9월의 경우 TWC 표층수 영향이 가장 강하게 영향을 미친 것으로 파악된다. 하지만 본 해역의 경우 하계 표층에 연안을 따라 북한한류(North Korea Cold Current; NKCC)의 기원으로 추정되는 냉수괴가 발달하며, 수괴의 특징은 수온과 염분은 낮고(15℃ 내외), 용존산소는 높은 것으로 알려져 있다(Lee and Kim[2003]; Suh and Hwang[2005]; Lee and Jang[2014]). 냉수괴가 발달하는 요인으로 동해남부해역에서 TWC의 저기압성 순환, 울기-감포 해역에서 발달한 동한난류로 인한 등온선 경압사면, 한국 동해남부 연안 주변 해역의 지형적 특징 그리고 남서풍의 지속 등으로 알려져 있으며, 출현 시기도 대부분이 6~8월에 집중되어 있다. | |
