The circulation of carbon in the biosphere, atmosphere, and hydrosphere through a series of processes that include photosynthesis, consumption, and respiration.
Congress asked us (in the Energy Independence and Security Act of 2007) to figure out how to assess the effects of carbon storage, sequestration, and greenhouse gas fluxes in our ecosystems. Here's how we plan to do that.
Explains what biochar is and how it is formed, its potential use in both fertilizer and carbon sequestration, and some of the research questions remaining to be addressed before we can utilize it fully in practical ways.
Summary of part of the USGS interdivisional Mississippi Basin Carbon project that will study the changes in climate and the environment through carbon cycle changes recorded in lake sediments in the Upper Mississippi River Basin.
Understanding how carbon and nutrients cycle in forests (forest biogeochemistry) is crucial for evaluating productivity, composition, diversity and change in forests.
