Marine Calcium Carbonate Biogeochemistry
Our state-of-the-art laboratory at Woods Hole Oceanographic Institution focuses on marine organisms that grow shells in the ocean, and their relationship to the marine carbon and alkalinity cycles. We conduct experiments and make measurements in the lab and in the field, using a combination of novel instrumentation and innovative approaches to traditional carbonate chemistry measurements.
** A note for these momentous times we are living in. Environmental research is social justice research. Ocean research is social justice research. I am committed to making my lab a welcoming, inclusive space for Black and other underrepresented minority people of all genders and sexual orientations. Please do not hesitate to reach out if you want to get engaged, or want to know more about how I am engaging with racism issues at WHOI. **
