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.

Airborne Taxonomic Mapping System (AToMS)
The most recent and technologically advanced instrument and computing package for CAO is called AToMS, or Airborne Taxonomic Mapping System.
AToMS has four integrated sensing technologies: (i) High Fidelity Visible-Shortwave Infrared (VSWIR) Imaging Spectrometer; (ii) Dual-laser, waveform Light Detection and Ranging (wLiDAR) Scanner, (iii) High-resolution Visible-to-Near Infrared (VNIR) Imaging Spectrometer, and (iv) High-resolution Digital Imaging Camera.
AToMS is now in its fourth generation configuration, with advances in all sensors. It can map features on the Earth’s surface in three dimensions, including all terrestrial ecosystems and the human-built environment. AToMS can also image coral reefs and other aquatic habitats with spectral detail.
The Beta System operated from 2007-2009, providing spectral imaging through the Airborne Visible Infrared Imaging Spectrometer (AVIRIS) and three-dimensional imaging through a Carnegie single-laser Light Detection and Ranging (LiDAR) Scanner. The CAO Beta System was a research test-bed for the current AToMS airborne sensor package. The Beta System operated in California and Hawaii.
The Alpha System operated from 2006-2011, and consisted of a Visible-to-Near Infrared (VNIR) Imaging Spectrometer and waveform Light Detection and Ranging (wLiDAR) Scanner. The Alpha System made major contributions to ecological science and conservation studies in California, Colombia, Hawaii, Madagascar, Panama, Perú, and South Africa.

"CAO provided a whole new perspective on the lives of animals in the rainforest canopy. We were able to trace how primates move through this complex, three-dimensional landscape exactly as they see it."− Kevin McLean, Yale University
"CAO lifted the veil on biogeochemical heterogeneity of rainforests in Costa Rica. In a single day, CAO revealed landscape patterns that would of taken a lifetime of field work to discover."− Phil Taylor, University of Colorado
"The CAO was integral in tying together ground-based knowledge of savanna ecology and community-based natural-resource management to understand drivers of woody vegetation structure in South Africa."− Jolene Fisher, University of Witwatersrand
"Development of the high fidelity VSWIR instrument with CAO has resulted in a new class of imaging spectrometer for 21st century science and application research."− Robert O. Green, NASA
"I flew with the CAO over the Amazon, reporting their research about the complex dynamic between climate change and rainforests. CAO imagery was an invaluable tool for effectively explaining this research to a general audience."− Simeon Tegel, Journalist
"We used the CAO to reveal fascinating geographic patterns of termite mounds in African savannas, and used them to predict the ecological effects of climate change."− Shaun Levick, Max Planck Institute
"The CAO was pivotal in mapping suitable habitat for rare and endangered species in tropical dry systems Hawaii."− Susan Cordell, US Forest Service
Our latest thoughts on our research, conservation and the environment
The CAO Coral Reef Challenge
Gregory P. Asner, September 2017
Coral reefs are global hotspots of biological diversity and support the livelihoods of more than a billion people worldwide. Coral reefs cover roughly 500,000 km2 of the Earth’s surface, but are sparsely distributed over more than 200 million km2 of ocean (Figure 1). Field studies currently represent less than 0.01% of coral reefs worldwide, and although local monitoring is important, it provides little understanding of the trajectory of coral reefs undergoing regional and global environmental change.

KONA, Hawaii – Hawaiian lawmakers are considering a ban on some popular sunscreens to try to protect coral reefs.
Researchers found that oxybenzone, a UV filtering ingredient commonly found in lotions, harms the coral. Up to 14,000 tons of sunscreen wind up in coral reef areas of the ocean every year, and scientists say that contributes to the ecosystem’s damage.
The Big Island of Hawaii’s pristine coastline is home to one of the state’s largest coral reefs, a miles-long stretch that scientists say is dying at an alarming rate.
