Victoria Alcock

Academic Profile

2020-2021, Research and Laboratory Assistant, British Antarctic Survey Following my master’s degree I spent a year at BAS as a research and laboratory assistant working on marine sediment cores in the Palaeoenvironments, Ice Sheets, and Climate Change team. 2016-2020, BA, MSci Natural Sciences, University of Cambridge For my MSci research project I studied cation exchange in some of Earth’s major river basins, and the implications cation exchange may have for estimates of global silicate weathering flux and associated long-term carbon consumption. We found that ion-exchange reactions between ancient clays and contemporary river waters have compromised weathering estimates based on river chemistry, resulting in a global overestimation of silicate weathering fluxes by up to 28%.

Nominated for the Curry MSc Prize (Geologists Association, 2020).
Awarded an Honorary Scholarship & College Prize (Clare College, 2020).
Awarded the CASP Prize (Cambridge Arctic Shelf Programme, 2019) 2019, Research Assistant, British Antarctic Survey.

Between my undergraduate and master’s degrees I spent a summer as a research assistant at BAS/Cambridge Earth Sciences working on a west Antarctic ice core in the Ice Dynamics and Palaeoclimate team.

Current Research

I am interested in understanding chemical weathering processes in the present day and through geological time, and how these processes interact with the wider carbon cycle. I use geochemical tools such as isotopes and trace element proxies to track and quantify chemical reactions during weathering. My DPhil project ‘Novel isotopes to help track CO2 release during rock weathering’ focuses on using and developing rhenium and vanadium isotope methods to track oxidative weathering reactions, particularly organic carbon and sulfide oxidation in shales.
