Improving Tools to Track Carbon Emissions

April 10, 2024

Modifications made to an existing open-source carbon dioxide (CO2) sensor allows researchers to more efficiently collect CO2 concentration data from moving bodies of water, such as streams and rivers, and better understand the role that they play in carbon cycling and global carbon dioxide emissions. Read more in the UNH Today feature about PIE researcher Wil Wollheim’s research focusing on adapting carbon dioxide sensors for streams and rivers.
