Abstract:
Concentrations of the sea-ice biomarker IP25 and highly branched isoprenoid triene (HBI III) (ng/g), total organic carbon content (TOC; %), IP25 and HBI III concentrations normalized to TOC (ng/gTOC), and fluxes of IP25 and HBI III (ng/unit surface area/yr) from the marine sediment core AMD14-204_CASQ that was retrieved from the West Greenland shelf, offshore Upernavik, and which spans the last ca. 9,000 years.

Comment:
Fluxes are calculated as follows:
Concentrations (ng/g) x sediment density derived from CT-Scan (HU) x accumulation rate (cm/yr).
To avoid confusion, the fluxes are expressed as ng per unit of surface area per year in the paper.
Trends can be compared, but flux values should not be directly compared with fluxes expressed with other units (e.g., ng/cm²/yr).
