NSF OPP Fellowship — Antarctic Blue‑Ice Geochronology

This project develops an 87Sr/86Sr chronometer from sea‑salt inclusions to date >1 Ma blue‑ice stratigraphy using LA‑ICP‑MS imaging.

  • Funding: NSF OPP Postdoctoral Fellowship (Award 2420291)
  • Methods: LA‑ICP‑MS, Sr isotopes, micro‑analytical mapping
  • Outcomes: 2D isotope maps, age‑depth models, calibration datasets
