Sampling soil carbon dioxide on Santa Rosa Island
Detailed Description
USGS Scientist sampling soil gasses from a grassy hilltop soil on Santa Rosa Island, Channel Islands National Park, California. The composition of soil gasses is indicative of the number and variety of microorganisms in the soil and what type of material they are digesting. Santa Rosa Island was heavily impacted by grazing animals and learning about soil microorganisms improves our understanding of these impacts and contributes towards efforts to mitigate them.
