Assessing GDGT-derived (sub)surface temperature proxies in Arctic fjord sediments: A 14 kyr record from the Kongsfjorden Trough, Svalbard
Read it here

•We evaluate OH-isoGDGT proxies in Kongsfjorden over the past 14 kyr.
•Temperature controls OH-isoGDGT, with terrestrial and hydrographic effects.
•RI-OH′ best reflects subsurface (0–200 m) temperature variability.
•Subsurface warming peaks at ~8–7 cal kyr BP, followed by late Holocene cooling.
•RI-OH′ is suitable for subsurface reconstructions in Arctic fjord–shelf systems.
