동해에서 알케논 합성 수심과 계절적 변화

Abstract

In order to investigate the depth and season of alkenone production in the East Sea. We have analyzed sea water samples collected from the East Sea during the 2008-2010 East Sea observations cruise of National Fisheries Research and Development Institute Korea. We collected suspended material from surface water(3 m) and subsurface water(20, 50, 70, 100 m). The alkenone concentration of surface water samples was the lowest in winter. Alkenone concentration of subsurface water samples was high in the mixed-layer. Alkenone-derived temperature of subsurface waters samples correspond to CTD in situ temperature within mixed-layer. Ours results mean that the alkenone in the East Sea would be synthesized in the mixed-layer.
