Occurrence and distribution of hydroxylated isoprenoid glycerol dialkyl glycerol tetraethers(OH-GDGTs)in the Han River system,South Korea
We investigated the occurrence and distribution of terrestrial-derived hydroxylated isoprenoid glycerol dialkyl glycerol tetraethers(OH-GDGTs)in the Han River system and their potential impact on the application of the ring index of OH-GDGTs(RI-OH)as a sea surface temperature(SST)proxy in the eastern Yellow Sea.Thereby,we analyzed various samples collected along the Han River and from its surrounding areas(South Korea,n=36).The OH-GDGTs were found in all samples investigated.OH-GDGT-0 was the dominant OH-GDGT component in the estuary and marine samples while OH-GDGT-2 was dominant in the soils,the lake sediments and the river suspended particulate matter(SPM).Our results suggests a possible warm bias of the RI-OH-derived summer SSTs in the coastal zone to which a large amount of terrestrial organic matter is being supplied.Further studies are necessary to better assess the applicability of the RI-OH proxy in the eastern Yellow Sea.
