The Global Ecosystem Dynamics Investigation

The Global Ecosystem Dynamics Investigation

The Global Ecosystem Dynamics Investigation (GEDI) is a NASA mission to place a waveform lidar instrument on the International Space Station. It will collect billions of measurements of the vertical distribution of vegetation within 22-m circular footprints worldwide to quantify aboveground carbon stocks in the world’s forests. This effort will provide a quantitative, globally consistent, and transparent […]

Canopy tree population genomics and foliar chemistry

Canopy tree population genomics and foliar chemistry

Canopy trees are long-lived organisms that produce a staggering number of offspring (seeds) in their lifetimes, very few of which will survive through juvenile life stages to eventually become adults themselves. What sets apart these proven winners in the competition for a position in the canopy? This project addresses this question in two ways. By […]

The CARBONO Project

The CARBONO Project

Each day, forests take up a tremendous quantity of carbon by way of photosynthesis. Over time, this carbon accumulates in plant tissues, where it resides until trees are cut down or die naturally and decompose, or are burned to clear land for agriculture. In addition to sequestering carbon through photosynthesis, forests continually release carbon to […]
