John Wesley Powell Center
The Powell Center serves as a catalyst for innovative thinking in Earth system science research by providing the time, creative space, & computational, data manipulation & data management resources to promote synthesis of existing information leading to emergent Earth System science knowledge.
Science and Products
Scaling tropical wetland methane fluxes regionally and globally
Wetlands purify water and remove atmospheric carbon dioxide but emit the greenhouse gas methane. Tropical wetlands are both one of the largest natural sources of methane and one of the least studied and understood ecosystems on earth.
Identifying root causes of thiamine deficiency complex in global aquatic ecosystems
Thiamine deficiency complex (TDC) is considered one of the top threats to global wildlife, yet we have a poor understanding of the drivers or extent of TDC or the reason(s) why it appears to be increasing in frequency.
Critical zone as a mediator of hydroclimate-ecosystem asynchrony
Most regions across the continental United States are experiencing shifts in hydroclimate, such as snow transitioning to rain and changes in streamflow regimes, driven by rising air temperatures.
A Global Synthesis of Flood Impacts: Understanding the Country-level Vulnerability and Causes
The escalating flood impacts on natural resources, built infrastructure, and human society have become a pressing global concern in the 21st century.
Are we experiencing a riverine silicon surge? Implications for the global carbon cycle
The amounts of silicon (Si), nitrogen (N), and phosphorus (P) in rivers are crucial for determining which types of algae grow.
Defining subsidy–stress gradients for metals and relevance for US surface waters
Metals like iron, copper, and zinc are naturally occurring in soils and water, and they are important essential nutrients for animals and plants.
Improving airborne disaster response coordination and communication with real-time open environmental data
Air pollution exposure in the United States is worsening due to changes in the environment and extreme natural events, such as wildfires and volcanic eruptions.
