River Corridor SFA: River Corridor Hydrobiogeochemistry from Reaction to Basin Scale

The River Corridor Scientific Focus Area works to improve understanding of the changes in space and time on the hydrobiogeochemical functions of river corridors, from molecular reaction to watershed and basin scales. We use the knowledge we gain to improve representation of river corridor processes, and their response to disturbances, in multiscale models of integrated hydrobiogeochemical function.

Keywords	AI/ML, biogeochemistry, biogeochemistry Studies the cycle of key elements like carbon, nitrogen, and phosphorus within Earth's systems. It explores how these elements interact and the factors influencing their cycles.

When rain falls to the ground, a portion percolates (sinks) into the ground and collects in spaces in the underground rocks. Source: A student's guide to Global Climate Change Source hydrology, hydrology The science that deals with water, its properties, circulation, or distribution on Earth's surface, and in the atmosphere through evapotranspiration. Source: NASA earth observatory Source microbial ecology, microbial ecology Studies the relationships of germs across many settings, including the diversity and abundance of germs within microbiomes.

PyOM can represent a large portion of total soil organic carbon in fire-affected systems, and where PyOM is added intentionally as a soil amendment.
