Dataset: Plant species determine tidal wetland methane response to sea level rise

This dataset accompanies the published paper Mueller et al. (2020) in the journal Nature Communications. We determined methane emissions from field-based mesocosms exposed to different global-change treatments (i.e. sea-level rise, elevated CO2, eutrophication) in two so-called marsh-organ experiments. Methane emissions from field-based mesocosms were compared to emissions from the adjacent field site. The studies were conducted at the Smithsonian Global Change Research Wetland (https://serc.si.edu/gcrew), a mesohaline, microtidal wetland site on Rhode River, a sub-estuary of the Chesapeake Bay (Maryland, United States). Additional data include plant-species composition, various plant-biomass parameters, and soil redox data.
