Graduate students in the Geological Oceanography course investigate the local coastal morphology, and discuss impacts of rising seas on our coastline with Professor Ralph Lewis.
15 April 2019. Dr. Emma Cross from the Baumann Lab just published her latest paper about brachiopod resilience to future ocean acidification in Environmental Science & Technology. The project involved long-term culturing of a polar and a temperate brachiopod under future ocean acidification and warming conditions during Emma’s PhD-research with the British Antarctic Survey. Substantial shell dissolution posed a threat to both species under ocean acidification, with more extensive dissolution occurring in the polar species.
Unexpectedly, however, the authors also discovered that brachiopods thicken their shell from the inner shell surface when extensive dissolution occurs at the outer shell surface under ocean acidification. This important finding furthers our understanding how predicted vulnerable marine calcifiers might cope under future environmental change.
