Enhancing C Sequestration in Terrestrial Ecosystems: Linking C and N cycling in soils (Part of Center for Research on Carbon Sequestration in the Terrestrial...., PNNL SCOPE # 30929).

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Vanessa Bailey

Project type

Exploratory Research

The objective of this research was to determine how N can control the C cycle in soils. We incubated soils from 5 different ecotypes with varying amounts of N and a fixed amount of C. At…

Dissection and Deciphering of the Soil Microbiome

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Janet Jansson

This proposal aims to address key gaps in our knowledge about the composition and functional roles of the tens of thousands of microbial species in soil. Although these microorganisms carry out…

Effect of drought duration on C mineralization

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Sarah Fansler

Drought and inundation events have been linked to increases in SOM availability and carbon mineralization. The duration of a drought event impacts the ability of the soil microbial community to…

Principal Investigator

Nancy Hess

Project type

MONet

To more fully understand the cycling of carbon, carbon-based nutrients and key elements from the molecular to basin scale across variations in soil chemistry, the Environmental Molecular Sciences…

Harnessing Biomineralization Potential of Metal-Oxidizing Bacteria for REE Synthesis

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Alex Beliaev

Although redox reactions and enzymes participating in the extracellular oxidation of Fe and Mn are identified, little is known about the biomineralization mechanisms that facilitate formation…

Do Your Gut Microbes Make You Moody?

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Sneha Couvillion

Attention-Deficit/Hyperactivity Disorder (ADHD) is a chronic neurodevelopmental disorder affecting 5- 9% of children and substantial numbers of adults. Co-occurring irritability or mood dysregulation…

River Corridor Hydrobiogeochemistry from Reaction to Basin Scale

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator
