Research interests: The role of wetlands in mitigating the effects of climate change

 

Biography

I grew up and studied in Barcelona, Spain, although I spent a fair amount of time in Australia during my undergrad and PhD. There, I discovered my fascination for marine sciences and decided to pursue a career on this field. I am interested in carbon biogeochemical cycling, ecosystems dynamics and the use of radionuclides and tracers in environmental records/materials to study present, past and future processes related to climate change. My research focuses in understanding the capacity of Blue Carbon ecosystems in storing carbon at different time scales and under different conservation status. Currently, I am a NOAA Climate and Global Change post-doctoral fellow at the Berkeley Biometeorology Lab (UCB) and Biogeochemistry lab (UCSC). I study the balance between carbon burial, carbon emissions and lateral export in different wetland types as well as the processes that control soil organic matter decomposition and associated CO2 and CH4 emissions.

Research

The role of wetlands in mitigating the effects of climate change and in sequestering CO2 depends on the efficiency with which organic C is incorporated into soils, versus exported to coastal waters and/or offset by CH4 emissions. My project aims to estimate the net ecosystem carbon balance of different types of wetlands, e.g., intact and restored, tidal and impounded and saline versus freshwater. Results will serve to advise how GHG fluxes may change if wetlands are restored and how to optimally design wetland restoration projects to maximize C uptake and minimize GHG production.
