Secondary Organic Aerosol (SOA) Markers Detected in a Mount Elbrus Ice Core
GB/NERC/BAS/PDC/02255
Abstract:
This dataset consists of a single CSV file containing the following organic marker concentrations: 2-methylerythritol, 2-methylglyceric acid, keto-pinic acid, pinic acid, cis-pinonic acid, 3-MBTCA, pinolic acid, cis-norpinonic acid, and nopinone. Concentrations of SOA markers detected in an ice core drilled from Mount Elbrus in 2020. The top 82 m of the core (707-2011 CE) was analysed utilising HPLC-MS. Quantified SOA markers have been utilised as proxies in Bushrod-Hicks, E. E., et al., 2026 to reconstruct land use change in Europe and the Mediterranean in response to historical events and climate changes.
This work was funded by a Leverhulme Grant: RPG-2024-362. Equipment used in this study was purchased with support from the University of Cambridge Yusuf Hamied fund. Work completed by Emilia E. Bushrod-Hicks was funded by an EPSRC DTP (grant reference number: EP/R513180/1) and a studentship awarded by the University of Cambridge Philosophical Society. The field team which recovered the Elbrus ice core were in the frame of RSF-25-17-00070.

| Quality: | Quantifying and qualifying transitions were studied through HPLC-MS/MS analysis using multiple reaction monitoring (MRM) mode. Each sample was run in duplicate with a MilliQ blank separating individual samples. Calibration standards were run at the start of each analysis session and control standards were placed at varying time intervals throughout analysis. Datapoints of more than 4 times the standard deviation of individual compound datasets were assessed as suspected outliers. Missing data are presented as empty cells. Full methodology is described in Bushrod, E. E., et al., 2024 (https://doi.org/10.1021/acs.est.4c09985) and Bushrod-Hicks, E. E., et al., 2026 (in review). | |
| Lineage/Methodology: | Seven hundred and eighty six discrete ice core sample fractions of approximately 3 mL were collected during a CFA campaign. These samples were analysed using HPLC-MS. Multiple reaction monitoring (MRM) mode with electrospray ionization (ESI) was utilised for target profiling. Each sample was run in duplicate with a MilliQ blank between samples. For each analyte, a quantifying and qualifying transition were analysed, and regular quality control standards were placed within runs at varying time intervals ranging from 30 hours to 65 hours between each standard set. Full methodology is described in Bushrod, E. E., et al., 2024 (https://doi.org/10.1021/acs.est.4c09985) and Bushrod-Hicks, E. E., et al., 2026 (in review). | |
