The NERC consortium project that initiated the ocean acidification mesocosm-based research at the MBA comprised 25 researchers from 12 organisations across the UK, and an international partner at Kristineberg Marine Research Station (part of Gothenburg University). Long-term laboratory experiments, field observations, numerical models and interdisciplinary workshops are being developed to provide an integrated, holistic ‘cells to ecosystems’ approach to tackle key questions about the impacts of ocean acidification in benthic systems. Mieszkowska has developed a thermal and CO2 controlled macrocosm system to investigate the long-term impacts of elevated temperature and decreased pH on juvenile survival and adult reproductive output of key climate indicator species. The results will feed into population and trophic models being developed by researchers at PML, SAMS and the MBA. The consortium will deliver the benthic component of the £12M, 5 year UK Ocean Acidification Research Programme (

Ocean Acidification: novel molecular studies on impacts on rocky shore biofilms and interactions with grazers are showing how temperature and pH alter food availability, quality and implications for keystone primary consumers, in collaboration with Dr Michael Cunliffe.
