ISOL-ICE
This project collected a shallow ice core from East Antarctic Plateau to reconstruct past ultraviolet radiation and therefore the ozone layer for the past 1,000 yr by measuring the isotopes of nitrogen and oxygen in the nitrate ion.
Holly Winton
After working at BAS as a Polar Atmosphere Ice Chemist between 2016-2019 on the ISOL-ICE project, Holly Winton is now a Rutherford Postdoctoral Fellow at the Antarctic Research Centre, Victoria University of Wellington in New Zealand. Her research aims to reconstruct past climate by investigating present day sources and processes of chemical impurities preserved in ice cores in order to interpret longer ice core records. To achieve this, she uses aerosols, snow and ice cores collected from a variety of environments from sub-tropical Savannah to the remote Southern Ocean and the Antarctic polar plateau to understand transport, deposition and archival processes of ice core proxies. Currently she is reconstructing past primary production using ice core biomarkers in the Ross Sea region of Antarctica. Holly’s research interests include atmospheric iron fertilisation, Antarctic dust provenance, and novel ice core proxies and biomarkers.
Holly collaborates with members of the Atmosphere Ice and Climate and the Ice Dynamics and Palaeoclimate teams at BAS. For more information about Holly’s research, see her research profile.
