Figure F3. Ion chromatograms (m/z 191) illustrating the abundance of hopanes for selected samples, Sites C0013, C0014, and C0017. Lithostratigraphic positions of samples and their locations within the Iheya hydrothermal system drilled during Expedition 331 are shown. αβ = 17α,21β(H) hopane; βα = 17β,21α(H); ββ = 17β,21β(H) hopane; Δ13 = hop-13-ene. Carbon numbers are noted.
