Event description

Description

Subglacial weathering plays a key role in carbon cycling within the Earth system. The various reactions involved in the chemical weathering of silicate and carbonate rocks in these environments can consume (or release) atmospheric carbon dioxide, and significant quantities of biologically important nutrients, such as phosphorous, iron and silicon are released. Changes in glacial melt rate are likely to have a significant impact on the input of these nutrients into the oceans, influencing marine biological production and atmospheric carbon drawdown.

Studying these weathering reactions is challenging as a result of sampling limitations and the complex nature of these environments, which contain both spatial and temporal variations in the types of bedrock being weathered and biological activity. Additionally, land-sea interactions occur over a wide range of scales, and vary both spatially and temporally.

Isotope geochemistry is the study of different forms of the same element with different masses, which vary in their relative abundance due to physical, chemical and biological reactions. It is possible to use isotopic ratios to trace these processes in nature, including the weathering of rocks and biological growth. Isotope geochemistry has the potential to resolve some of these confounding factors in glacial systems by unpacking different processes. In recent years, there has been an explosion in the range of isotopic systems available (e.g. iron, silicon, strontium, osmium, hafnium, neodymium, uranium, thorium…), many of which have been measured in the Bristol Isotope Group (BIG) laboratories based in the School of Earth Sciences at the University of Bristol.

However, we will gain the most information about the underlying processes in action under and around ice sheets by bringing together the large amount of existing data from different isotope systems with the large complementary datasets of glaciological processes.

This workshop aims to:

1) Work towards a meta-analysis of isotope geochemical data from glaciated regions, initially focusing on Greenland but also with the potential to cover other regions of the Arctic, Antarctic and non-polar glaciers (e.g. Chilean Patagonia).

2) Bring together scientists within the University of Bristol with expertise in glaciology and related subjects (e.g. satellite sensing, oceanography, ‘omics’) who will be able contribute to or gain from the interpretation of isotope geochemical data.

3) Bring together isotope geoscientists from around the UK to build on synergistic activities in different isotope systems utilised to constrain the same system, with the goal of targeted field sampling collaboration.

We would like to encourage early career researchers (including PhD students and PDRAs) to present their work in both talks and posters, with ample time for discussions.
