Muntsa Roca Martí is a postdoctoral researcher interested in studying the ocean biological carbon pump (BCP), a poorly constrained process that strongly influences atmospheric carbon dioxide concentrations and the distribution of chemical species in the ocean. During her PhD studies (ICTA-UAB, 2017), her research focused on filling critical gaps in the understanding of the BCP in the polar oceans. Her postdoctoral career began in Australia (Edith Cowan University, 2017-2018) where she worked on methods development to improve the application of naturally occurring radionuclides as BCP tracers. Then Muntsa moved to the USA (Woods Hole Oceanographic Institution, 2018-2021) and Canada (Dalhousie University, 2021-2023) to become part of large interdisciplinary BCP projects (EXPORTS, NWA-BCP) devoted to improve our ability to monitor and predict BCP changes on regional to global scales and understand their effects on climate and marine ecosystems. Since March 2023, Muntsa is holding a Beatriu de Pinós postdoctoral fellowship at ICTA-UAB with the objective to better constrain the magnitude of the BCP by bringing together traditional and emerging methods across different disciplines.
