After harvest, fields are reflooded to decay the remaining straw. This decaying material can fuel the bacteria that create methylmercury, even during the cold months.
Lisamarie Windham-Myers
Lisamarie Windham-Myers is a research ecologist in the Earth Systems Process Division of the Water Mission Area.
Broadly-trained in ecosystem ecology, her research focuses on the relative influences of wetland and estuarine characteristics on carbon, nutrient, and trace-metal biogeochemistry. Her approaches span landscape-to-molecular scales as necessary to understand how alterations of wetland structure influences wetland function. Lisa’s research sites represent a wide range of salinity and management conditions, from rice agriculture to coastal and restored wetlands. Since 2000, she has authored or coauthored over 100 peer reviewed papers on wetland biogeochemistry, and co-produced functional maps of wetland elevation and soil characteristics. From local to national to global assessments, Lisa represents USGS capabilities and interests across the aquatic continuum to improve management of wetlands under climate and landuse-change scenarios.

Science and Products
Building a roadmap to integrate freshwater wetlands into the National Greenhouse Gas (GHG) Inventory
Inter-agency, in-person, collaborative workshop with scientists and stakeholders to fill a major information gap.
Wetland Carbon Working Group: Improving Methodologies and Estimates of Carbon and Greenhouse Gas Flux in Wetlands
WARC researchers are working to quantify the impacts of future climate and land use/land cover change on greenhouse gas emissions and reductions.
USGS Blue Carbon Projects
Together with partner organizations, the USGS is involved in data collection, analysis, and synthesis to improve estimates of coastal wetland carbon fluxes. This research will help improve science and data availability across a wide range of topics.
Creating a Model to Predict Future Carbon Levels in Tidally-driven Marshes
Tidal marshes are important ecosystems in the San Francisco-Bay Delta. They remove carbon from the atmosphere, they build up soils that buffer our communities from sea level rise, they provide critical habitat and food resources for a diversity of species, and they reduce excessive nutrients which have a negative impact on water quality. As a result of land-use change and urbanization, the San...
Global Science and Data Network for Coastal Blue Carbon (SBC)
The Global Science and Data Network for Coastal Blue Carbon (SBC) brings together scientists from a wide range of disciplines. Our goal is to increase the accuracy of and confidence in local, regional, and global estimates of carbon cycle processes, fluxes, and storage as well as greenhouse gas emissions from coastal ecosystems, and to allow global access to quality controlled coastal ecosystem...
NASA-USGS National Blue Carbon Monitoring System
The NASA-USGS National Blue Carbon Monitoring System project will evaluate the relative uncertainty of iterative modeling approaches to estimate coastal wetland (marsh and mangrove) C stocks and fluxes based on changes in wetland distributions, using nationally available datasets (Landsat) and as well as finer scale satellite and field derived data in six sentinel sites.
Assessing the Benefits and Vulnerability of Current and Future Potential Ecosystem Services of the Nisqually River Delta and other Puget Sound Estuaries
The Nisqually River Delta represents the largest wetland restoration in the Pacific Northwest. The restoration resulted in a 50% increase in potential salt marsh habitat. The Delta supports threatened salmon fisheries, large populations of migratory birds, and provides unique opportunities for recreation. The Delta also provides multiple ecosystem services, which are the benefits that wildlife or
Wetland fluxnet synthesis for methane: understanding and predicting methane fluxes at daily to interannual timescales
Wetlands provide many important ecosystem services, including wildlife habitat, water purification, flood protection, and carbon metabolism. Our ability to manage these services and predict the long-term health of wetlands is strongly linked to their carbon fluxes, of which methane (CH4) is a key component. Natural wetlands emit approximately 30% of global CH4 emissions, as their waterlogged soils
Integration of National Soil and Wetland Datasets: A Toolkit for Reproducible Calculation and Quality Assessment of Imputed Wetland Soil Properties
Wetland soils are vital to the Nation because of their role in sustaining water resources, supporting critical ecosystems, and sequestering significant concentrations of biologically-produced carbon. The United States has the world’s most detailed continent-scale digital datasets for soils and wetlands, yet scientists and land managers have long struggled with the challenge of integrating these d
