Overview

Stewart P.H.T. Freeman is a researcher affiliated with the University of Glasgow in the United Kingdom. Their work spans multiple disciplines within Earth and Environmental Sciences, focusing predominantly on fields such as Atmospheric Science, Ecology, Paleontology, Earth-Surface Processes, and Environmental Chemistry. Freeman's research interests include Geology and Paleoclimatology, Cryospheric Studies, Polar Research and Ecology, Isotope Analysis in Ecology, Archaeology and Ancient Environmental Studies, Geological Formations and Processes, and Methane Hydrates and Related Phenomena.

Freeman has contributed to academic literature through various recent papers published in specialized journals. These include:

  • "Combined unsteady denudation and climatic gradient factors constrain carbonate landscape evolution: New insights from in situ cosmogenic 36Cl" (2020), published in Quaternary Geochronology
  • "Ice-free valleys in the Neptune Range of the Pensacola Mountains, Antarctica: glacial geomorphology, geochronology and potential as palaeoenvironmental archives" (2021), published in Antarctic Science
  • "Clean quartz matters for cosmogenic nuclide analyses: An exploration of the importance of sample purity using the CRONUS-N reference material" (2022), published in Quaternary Geochronology
  • "A DATABASE OF NERC RADIOCARBON MEASUREMENTS DETERMINED BY ACCELERATOR MASS SPECTROMETRY" (2023), published in Radiocarbon
  • "Another 6 years of radiocarbon secondary-standard AMS with two spectrometers" (2022), published in Nuclear Instruments and Methods in Physics Research Section B Beam Interactions with Materials and Atoms

Freeman frequently collaborates with other scientists, with notable co-authors including:

  • Sheng Xu (4 joint publications)
  • David Small (3 joint publications)
  • Michael J. Bentley (3 joint publications)
  • Klaus M. Wilcken (2 joint publications)
  • Pauline Gulliver (2 joint publications)

The researcher has published primarily in venues such as Quaternary Geochronology, Antarctic Science, Radiocarbon, and Nuclear Instruments and Methods in Physics Research Section B Beam Interactions with Materials and Atoms, with multiple publications appearing in Quaternary Geochronology and contributions also appearing in the SSRN Electronic Journal.

Freeman's contributions are characterized by a focus on isotopic and radiocarbon dating techniques, as well as geomorphological and environmental analysis in polar and other ecological contexts. Their work addresses fundamental questions related to landscape evolution, glacial geomorphology, and the precision of measurement techniques for dating samples in Earth sciences.
