X-raying coral reefs and rainforests from the sky

A conversation with Robin Martin and Greg Asner about cutting-edge conservation technology.

Robin Martin and Greg Asner have pioneered the use of advanced LiDAR and spectrometer sensors to study tropical forest ecosystems, revealing information about biodiversity, habitat function and health, and ecosystem services. Their work has been widely profiled by the likes of Science Magazine, National Geographic, and hundreds of other outlets. They've now turned their system to coral reefs, which may support the development of the first comprehensive global reef monitoring system in an era when the world's corals are deeply threatened by rising temperatures, growing carbon emissions, and unsustainable fishing and extraction. Rhett Butler, founder of conservation news web site, will talk with Robin and Greg about how technology can help protect an conserve these critical ecosystems.
