Abstract:
Stable-carbon isotope compositions for crenarchaeol, bacteriohopanetetrol I (BHT-I), and bacteriohopanetetrol II (BHT-II) for ODP cores at sites 964 and 967. All biomarkers were measured using a Thermo Scientific Delta V isotope ratio mass spectrometer at least in triplicate. For BHT-I and BHT-II, compounds were isolated using high-performance preparative liquid chromatography and individually analyzed by high-temperature gas-chromatography-IRMS following Hemingway et al. (2018). Crenarchaeol was isolated using high-pressure preparative chromatography and analyzed using a spooling-wire microcombustion interface on a Thermo Scientific Delta V isotope ratio mass spectrometer at least in quintuplicate following Polik et al. (2018).

Comment:
Carbon stable isotopic composition of crenarchaeol (δ13C Cren.), bacteriohopanetetrol I (δ13C BHT-I), and bacteriohopanetetrol II (δ13C BHT-II). F2/F1 size ratio describes the crenarchaeol-carbon to background-carbon ratio as an indicator of potential bias δ13C Cren by high background. Values above 2 indicate unbiased samples (Polik et al., 2018). Differences between δ13C Cren, δ13C BHT-I, and δ13C BHT-II are given.
