Work smarter and harder: a fieldwork fable involving the investigation of lake greenhouse gas emissions

“Are you sure this is the ramp?” my colleague, Dr. Jake Beaulieu asked the head field researcher, Adam Balz, as we drove up to the site.

The three of us took in the view of the crumbling asphalt inclined plane that disappeared into the lake. According to the map, this was the boat launch. But the usage of the lake had changed from allowing motorized craft to “paddle craft only” several years ago, and now the disused ramp was covered in layers of sandy sediment.

Watching Grass Grow from Space: NASA’s Orbiting Carbon Observatory-2 Satellite Gives Insights into Photosynthesis and Climate Change

The mission of NASA’s Orbiting Carbon Observatory-2 satellite is to improve our understanding of the factors that control global carbon dioxide levels. The satellite was designed to measure atmospheric carbon dioxide, but it can also detect a signal of plant photosynthesis — a key carbon sink. NASA scientists are working to use these two pieces of information together to disentangle natural and human influences on the carbon cycle.

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.
