This data publication contains the concentration (in µg/g) of the triene Z and the diene highly branched isoprenoids, along with their ratio, versus depth (in meters below sea-floor) and age (in years Common Era) in core IODP U1357B. Core IODP U1357B was retrieved in the Dumont d'Urville Trough off Adélie Land, East Antarctica, during the IODP expedition 318 "Wilkes Land Glacial History" conducted on board the R.V. Joides Resolution during the austral summer 2010. The diatom-specific biomarkers were produced to document changes in sea-ice conditions off Adélie Land at decadal timescale over the last 2000 years.
