| Research Abstract |
To develop paleo-SST proxy by using GDGTs archaea membrane lipids from sediments, we need to know the ecological knowledge of marine archaea in the water column. In this study, we collected filtrated samples from several deoth in Suruga bay to analyze the 14C of GDGTs and DOC, DIC, POC. The Δ14C values of GDGTs from 700 m water dpth was -400‰ and DIC and DOC were 140‰ and -700‰, respectively. The results of GDGTs, DIC and DOC was significantly different from each other, suggesting that various sources and depth distributions of marine archaea was occurred
