[Lab news] Emma Cross now at Southern Connecticut State University

25 August 2019. We are happy to announce that Dr. Emma Cross has started her new faculty position as Assistant Professor in Coastal/Marine Science at Southern Connecticut State University (New Haven, CT). Emma at the joined our team in September 2017 and worked tirelessly to investigate how fluctuating pH and oxygen environments typical of nearshore environments affect early life survival and growth. Emma was also instrumental in all of our follow-up, ongoing work on sand lance sensitivity to ocean warming and acidification.

Emma was an incredible enrichment to our lab, and her proximity will sure enable lots of collaborative work in the future!
A big hat tip to Emma!


[Publication] Brachiopods thicken shells to compensate for shell dissolution under future OA conditions

15 April 2019. Today, Emma is happy to report that Environmental Science & Technology have just published the latest paper from her PhD about brachiopod resilience to future ocean acidification. This project involved long-term culturing of a polar and a temperate brachiopod under future ocean acidification and warming conditions. Substantial shell dissolution posed a threat to both species under ocean acidification, with more extensive dissolution occurring in the polar species.

Unexpectedly, we discovered that brachiopods thicken their shell from the inner shell surface when extensive dissolution occurs at the outer shell surface under ocean acidification. This is an important finding to further our understanding of how predicted vulnerable marine calcifiers might cope under future environmental change.
