Autonomous vehicle helps measure gases in coastal ecosystems

Coastal ecosystems play an important role in the cycling of carbon, an element essential for life. However, coastal ecosystems are complex making it difficult to determine their exact contribution to carbon cycling with single point measurements. In the study highlighted here, David Nicholson and his colleagues introduce an autonomous (driver-less) surface vehicle that will allow for a better understanding of carbon cycling in coastal ecosystems.

Accounting for Greenhouse Gases: Methane in India

How do we know how much heat-trapping greenhouse gas there is in the atmosphere? What about where these greenhouse gases are coming from? Scientists work hard to answer these questions on global, national, and regional levels. Recently, a group of scientists from India, the United Kingdom, Germany, and the United States collaborated to evaluate India’s emissions of the greenhouse gas methane. This blog post explains how greenhouse gas accounting is similar to tracking your bank account. The post then discusses in more detail how the India study was conducted, and why its findings are important.
