Sheel Bansal, PhD
Sheel Bansal is a Research Ecologist at the USGS Northern Prairie Wildlife Research Center in Jamestown, North Dakota.
Dr. Bansal research experience covers a wide range of topics such as tree carbon balance at alpine-treeline (Wyoming), fertility effects on boreal plant ecophysiology (Sweden), drivers of grass invasion in sagebrush-steppe (Oregon), and drought tolerance of temperate forest trees (Washington). He is now studying wetland biogeochemistry in the Prairie Pothole Region. Much of the research in his lab is focused on understanding the underlying suite of abiotic and biotic mechanistic processes that influence greenhouse gas emissions and carbon storage in wetlands. His lab is developing new, high-tech equipment to more efficiently quantify the immense spatial and temporal variability of these natural processes. Dr. Bansal is also working with internal and external partners to develop spatially explicit, landscape-scale models to estimate regional carbon budgets for prairie pothole wetlands. These data and models provide DOI land managers and policy makers with information needed to understand, monitor, and anticipate changes in wetland carbon sequestration and greenhouse gas emissions under future management, land-use and climate scenarios.

Greenhouse gas fluxes, dissolved gas concentrations, and water properties of laboratory mesocosms Greenhouse gas fluxes, dissolved gas concentrations, and water properties of laboratory mesocosms
These data describe greenhouse gas (GHG) emissions, dissolved GHG concentrations, and mesocosm conditions (vegetation, hydrologic phases, ambient conditions) of a controlled, laboratory study.
Diurnal patterns of methane flux from a depressional, seasonal wetland Diurnal patterns of methane flux from a depressional, seasonal wetland
Data on diurnal variation in wetland methane flux were collected to 1) improve understanding of short-term, mechanistic drivers of methane flux, and 2) inform sampling protocols to achieve research objectives. An automated gas flux sampling system was used to measure methane flux every 2.5-4 hours for over 230 diel cycles over the course of three growing seasons (2013-2015). Data were...

Characterizing performance of freshwater wetland methane models across time scales at FLUXNET-CH4 sites using wavelet analyses Characterizing performance of freshwater wetland methane models across time scales at FLUXNET-CH4 sites using wavelet analyses
Process-based land surface models are important tools for estimating global wetland methane (CH4) emissions and projecting their behavior across space and time. So far there are no performance assessments of model responses to drivers at multiple time scales. In this study, we apply wavelet analysis to identify the dominant time scales contributing to model uncertainty in the frequency...

Submersed macrophyte density regulates aquatic greenhouse gas emissions Submersed macrophyte density regulates aquatic greenhouse gas emissions
Shallow freshwater ecosystems emit large amounts of greenhouse gases (GHGs), such as carbon dioxide (CO2) and methane (CH4), yet emissions are highly variable. The role that aquatic macrophytes play in regulating aquatic GHG emissions is uncertain despite their ability to dominate shallow waterbodies. Here, we studied the effects of submersed macrophyte (Ceratophyllum demersum) density...

Upscaling wetland methane emissions from the FLUXNET-CH4 Eddy Covariance Network (UpCH4 v1.0): Model development, network assessment, and budget comparison Upscaling wetland methane emissions from the FLUXNET-CH4 Eddy Covariance Network (UpCH4 v1.0): Model development, network assessment, and budget comparison
Wetlands are responsible for 20%–31% of global methane (CH4) emissions and account for a large source of uncertainty in the global CH4 budget. Data-driven upscaling of CH4 fluxes from eddy covariance measurements can provide new and independent bottom-up estimates of wetland CH4 emissions. Here, we develop a six-predictor random forest upscaling model (UpCH4), trained on 119 site-years...

Spatial and temporal variability in summertime dissolved carbon dioxide and methane in temperate ponds and shallow lakes Spatial and temporal variability in summertime dissolved carbon dioxide and methane in temperate ponds and shallow lakes
Small waterbodies have potentially high greenhouse gas emissions relative to their small footprint on the landscape, although there is high uncertainty in model estimates. Scaling their carbon dioxide (CO2) and methane (CH4) exchange with the atmosphere remains challenging due to an incomplete understanding and characterization of spatial and temporal variability in CO2 and CH4. Here, we...

Large increases in methane emissions expected from North America’s largest wetland complex Large increases in methane emissions expected from North America’s largest wetland complex
Natural methane (CH4) emissions from aquatic ecosystems may rise because of human-induced climate warming, although the magnitude of increase is highly uncertain. Using an exceptionally large CH4 flux dataset (~19,000 chamber measurements) and remotely sensed information, we modeled plot- and landscape-scale wetland CH4 emissions from the Prairie Pothole Region (PPR), North America’s...

Modeled production, oxidation, and transport processes of wetland methane emissions in temperate, boreal, and Arctic regions Modeled production, oxidation, and transport processes of wetland methane emissions in temperate, boreal, and Arctic regions
Wetlands are the largest natural source of methane (CH4) to the atmosphere. The eddy covariance method provides robust measurements of net ecosystem exchange of CH4, but interpreting its spatiotemporal variations is challenging due to the co-occurrence of CH4 production, oxidation, and transport dynamics. Here, we estimate these three processes using a data-model fusion approach across...

Towards critical white ice conditions in lakes under global warming Towards critical white ice conditions in lakes under global warming
The quality of lake ice is of uppermost importance for ice safety and under-ice ecology, but its temporal and spatial variability is largely unknown. Here we conducted a coordinated lake ice quality sampling campaign across the Northern Hemisphere during one of the warmest winters since 1880 and show that lake ice during 2020/2021 commonly consisted of unstable white ice, at times...

Using a vegetation index to assess wetland condition in the Prairie Pothole Region of North America Using a vegetation index to assess wetland condition in the Prairie Pothole Region of North America
Wetlands deliver a suite of ecosystem services to society. Anthropogenic activities, such as wetland drainage, have resulted in considerable wetland loss and degradation, diminishing the intrinsic value of wetland ecosystems worldwide. Protecting remaining wetlands and restoring degraded wetlands are common management practices to preserve and reclaim wetland benefits to society...

Classifying mixing regimes in ponds and shallow lakes Classifying mixing regimes in ponds and shallow lakes
Lakes are classified by thermal mixing regimes, with shallow waterbodies historically categorized as continuously mixing systems. Yet, recent studies demonstrate extended summertime stratification in ponds, underscoring the need to reassess thermal classifications for shallow waterbodies. In this study, we examined the summertime thermal dynamics of 34 ponds and shallow lakes across...

Prairie wetlands as sources or sinks of nitrous oxide: Effects of land use and hydrology Prairie wetlands as sources or sinks of nitrous oxide: Effects of land use and hydrology
National and global greenhouse gas (GHG) budgets are continually being refined as data become available. Primary sources of the potent GHG nitrous oxide (N2O) include agricultural soil management and burning of fossil fuels, but comprehensive N2O budgets also incorporate less prominent factors such as wetlands. Freshwater wetland GHG flux estimates, however, have high uncertainty, and...

Soil organic carbon (SOC) stocks of Prairie Pothole Region (PPR) wetlands in the central plains of Canada and the United States are highly variable due to natural variation in biota, soils, climate, hydrology, and topography. Land-use history (cropland, grassland) and land-management practices (drainage, restoration) also affect SOC stocks. We conducted a region-wide assessment of...
