The project aims to develop computational models to analyse the impact of ocean acidification on cold-water coral reefs. Results will be used in the development of monitoring strategies to preserve some of the most vulnerable ecosystems.
Cold-water corals (CWC) are key habitat-forming organisms found throughout the world's oceans from 30 to 3000 m deep which are threatened by climate change induced ocean acidification. The complex three-dimensional frameworks made by these vulnerable marine ecosystems support high biodiversity and commercially important species compared to neighbouring, less complex habitats. If this habitat complexity was reduced, the ability of these habitats to support high levels of biodiversity would decrease. Recent experiments suggest that this reduction is due to a reduced structural integrity of the coral skeleton. This would allow development of monitoring and assessment strategies of these ecosystems (similar to strength or lifetime analyses) based on the structural integrity of CWC reefs, and determination of how this may change under projected future ocean acidification scenarios.
The project aims at developing computational models of CWCs to compute failure rates and investigate the impact of acidification. Key tasks of the project are:
i. analysing CWC structure and porosity using existing µCT data,
ii. developing a multiscale mechanical model of the coral skeleton,
iii. developing image based computational models,
iv. integrating micromechanical experimental data into these models, and analysing strength comparing living and dead samples.
Given the importance of cold-water habitats the Secretariat of the Convention on Biological Diversity has recently stated that there is “a need to develop predictive model research to determine how projected climate change will impact cold-water biodiversity over different timescales”. If successful, this project will help to close this gap.
All applicants must have or expect to have a 1st class MChem, MPhys, MSci, MEng or equivalent degree by Autumn 2020. Selection will be based on academic excellence and research potential, and all short-listed applicants will be interviewed (in person or by Skype). This scholarship is only open to UK/EU applicants who meet residency requirements set out by EPSRC.
All applications must be received by 28th February 2020. All successful candidates should usually expect to start in September/October 2020.
