CAO Imagery as Art for Scientific Journals

Media Coverage, Research

Since its inception in 2006, CAO has produced interesting data art for numerous scientific journals. Making the December 2016 cover of Ecological Applications, this image shows CAO’s Visible-to-Shortwave Infrared (VSWIR) imaging spectrometer data over a reforested landscape in Panama. Different colors indicate differences in growth rates among tropical trees.

Wired Mag: Hyperspectral cameras can spot Alzheimer’s and disease in crops

Media Coverage

How can you tell if an avocado’s gone bad just by looking at it? By examining it through a hyperspectral (HS) camera. These devices – also known as imaging spectrometers – see things the human eye cannot by scanning the world across multiple channels of light. Where humans see three wavelengths in the colour spectrum (red, green and blue), hyperspectral sensors can detect as many as 480.

National Geographic: Tallest trees in the tropics discovered

Media Coverage

From a freezing hotel ballroom in Kota Kinabalu, an exciting announcement was made about the sweltering tropical forests in the Heart of Borneo, in an area on the interior of Southeast Asia that straddles the borders of Malaysia, Indonesia, and Brunei. Using laser-scanning technology known as Light Detection and Ranging (LiDAR), Greg Asner of Stanford University and the Carnegie Institution for Science revealed that his team had identified 50 new trees that break the previous record for the world’s tallest tropical tree announced earlier this year.

NPR Science Friday: California Trees Battle Beetle Assault Amid Drought

Media Coverage

Across the state of California, millions of trees are dying each year—but it’s not from old age. The ongoing drought is causing extreme water stress in many forests, which paradoxically leads trees to release pheromones that attract another threat: bark beetles. According to forest ecologist Christina Restaino, water stress also cuts the trees’ ability to produce sap, a first-line defense against beetles.

Limahuli Valley, Kauai

Limahuli Valley, Kauai

July 2016 marks the 10th anniversary of a scientific idea hatched in a distant valley along Kauai Island’s northern coast in the central Pacific. The 2006 conception was preceded by ten other years of research on the chemical properties of plant canopies in far flung environments ranging from desert shrublands to tropical rainforests. That preceding decade had cumulatively yielded just a hint that a tree-of-life approach to studying forests might be possible at the mother of all scales – Earth’s biosphere.
