Audio: The cutting-edge technologies allowing us to monitor ecosystems like never before

06 / 02 / 2018, Mongabaycom News

On today’s episode, we discuss the cutting-edge remote sensing technologies used to monitor ecosystems like rainforests and coral reefs. We also listen to a few ecoacoustic recordings that are used to analyze species richness in tropical forests. Listen here: Our first guest today is Greg Asner, who leads the Carnegie Airborne Observatory (CAO) at Stanford University’s Carnegie Institution for Science. Asner invented a technique he calls “airborne laser-guided imaging spectroscopy” that utilizes imaging spectrometers mounted on the Carnegie Airborne Observatory airplane to produce highly detailed data on large and complex ecosystems like tropical forests. Asner used that 3-D imaging technique to discover the tallest tropical tree in the world back in 2016, but he’s also used the technology to create ultra-high-resolution maps of coral reefs. Asner and his colleague Clare LeDuff will be documenting the progress of a new project called Reefscape right here on Mongabay, and he’ll tell us about that in addition to explaining the technologies he’s using to monitor the world’s rainforests. Our second guest is Mitch Aide, the principal investigator at the University of Puerto Rico’s Tropical Community Ecology Lab. Aide not only uses bioacoustics in his research, he’s also led the development of Arbimon, a web-based application for storing and analyzing bioacoustic data that aims to improve how we monitor land change and biodiversity across vast landscapes and long timeframes. In this Field Notes segment, Aide will play us a few of the audio recordings he’s uploaded to Arbimon as part of his recent research…
