Coastal wetlands provide numerous benefits such as flood protection, species habitat, and carbon storage. In fact, they capture and store more carbon than terrestrial forests, further reducing the negative impacts of climate change. Coastal wetlands in the San Francisco Bay – Delta are managed to maximize these benefits. Many of our projects are focused on measuring carbon in natural and restored Bay area wetlands. Long-term carbon storage can be measured by collecting soil core samples that are analyzed to detect organic carbon changes through time. Existing vegetation and soil microbe communities influence to the amount of carbon stored in the soil and how much carbon is released into the atmosphere. We use a greenhouse gas chamber analyzer to measure carbon dioxide and methane fluxes which can vary depending on soil type, salinity, vegetation communities, and tidal inundation. We are interested in understanding what drives carbon fluxes and storage to better inform coastal wetland management.
