Genevieve’s eXperiment is the newest experiment at the Global Change Research Wetland led by Genevieve Noyce. Using an automated methane chamber system, GenX aims to quantify rates of anaerobic decomposition pathways that regulate methane emissions across different time scales. Additional elements like warming, salinity, and inundation will also be incorporated to determine the individual and interactive effects of these variables on methane cycling.
We support the data infrastructure of the Salt Marsh Accretion Response to Temperature eXperiment which models how future climate predictions will influence salt marshes, by maintaining a network of 6 remote CO2 sensors and warming cables. SMARTX aims to assess plant response to interacting variables (elevated CO2, an increasing temperature gradient above- and below-ground, and changes in inundation frequency) at SERC’s Global Change Research Wetland.
The Marsh Ecosystem Response to Increased Temperature is a warming experiment replicating SMARTX infrastructure in collaboration with scientists at the University of Hamburg to measure how salt marshes will be impacted by elevated temperatures in a Northern Sea coastal ecosystem. We support MERIT by implementing Arduino-based technology to create an affordable wireless control network allowing for analyses of plant community responses, successional dynamics, carbon sequestration, and soil accretion.
Carbon in the Capital
Carbon in the Capital is a new CO2 monitoring citizen science project in collaboration with Ph.D. candidate Marc Rosenfield in the Zanne lab at George Washington University. Carbon in the Capital has deployed 33 of our CO2 sensors throughout all 8 Wards of Washington D.C. to monitor changes in emissions during COVID-19 lockdowns. So far, results capture important interplays between transportation emissions and natural signals, which can be significant to mitigating human impacts on the carbon cycle and urban greenhouse gas removal.

TeRaCON (Temperature, Rainfall, CO2, Nitrogen) is an 8-year-long novel global change experiment in collaboration with Dr. Peter Reich at the University of Minnesota. TeRaCON exposes vegetation in a Minnesotan temperate grassland to manipulated temperatures, rainfall patterns, CO2, and nitrogen to examine the effects of these global change drivers on terrestrial carbon cycling. For TeRaCON, we designed warming infrastructure to manipulate temperature; find more about TeRaCON and its findings in Nature Geoscience
