Experienced analytical chemist and ice core driller (medium depth (~120m) drill)
I lead the development of our BAS bespoke continuous flow analysis system (CFA). This system is used for the online melting of ice cores to retrieve high resolution, multi-trace chemical species used to inform us of past climate and environment
Since late 2017 I have developed a CFA system that enables the detection of the following parameters:
H2O2
NH4+
Ca2+
Conductivity
Dust (Abakus®)
NO3–, F–, SO4–, Cl–, and Methanesulfonic Acid (Fast ion chromatography)
I work closely with leading scientist Robert Mulvaney and expert engineers Julius Rix and Seth Thomas to continually develop this system to meet different ice core project requirements.

SUBICE, the Sub-Antarctic – ice coring expedition, part of the international Antarctic Circumnavigation Expedition (ACE), successfully drilled several shallow ice cores, from five of the remote and globally significant sub-Antarctic islands.
Studying ice response during past climate changes improves understanding of Antarctic ice sheet dynamics. This knowledge helps predict how ice sheets may behave under future warming scenarios.
This project used ice cores drilled across the Antarctic Peninsula and West Antarctica to reconstruct past climate and understand whether the recent warming in these rapidly changing regions is unusual over longer timescales..
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.
iStar-D will identify the potential contribution to sea-level rise, from ice locked in the Amundsen Sea sector of Antarctica
