Symposium ‘Carbon Cycling in Coastal Environments’, 31 August 2022, Brussels

Coastal environments are under strong pressure from human activity but could also help us battle climate change. A promising method to remove CO2 from the atmosphere is to distribute silicate minerals in coastal areas since the chemical reaction that occurs when silicate minerals weather allows the ocean to take up more CO2. The new project DEHEAT will investigate the feasibility of using silicate weathering in coastal areas to remove CO2 from the atmosphere. This will be done by field studies of sites where silicate weathering rates are naturally high, and by modelling.

To kick off the project, the DEHEAT consortium organises a one-day symposium about carbon cycling in coastal environments on the 31st of August 2022. Covering a broad range of topics, the symposium will be a platform for networking and discussions about questions at the forefront of science. The symposium will be held in the Grand Auditoire at the Museum of Natural Sciences (Royal Belgian Institute of Natural Sciences), Rue Vautier 29, 1000 Brussels. Attendance is free, but registration here before the 1st of August is required.

DEHEAT is a Belspo-funded project under the RV Belgica call, runs from 2022 to 2026 and is coordinated by the Royal Belgian Institute of Natural Sciences with partners at Universiteit Antwerpen and Université Libre de Bruxelles.
