PENN SCIENCE CAFÉ - Remote Sensing: The Earth's Increasingly Helpful Physician
PENN SCIENCE CAFÉ - Remote Sensing: The Earth's Increasingly Helpful Physician
Jane Dmochowski, senior lecturer in the Department of Earth and Environmental Science, School of Arts & Sciences
In 1858, combining the inventions of the camera and the hot air balloon, French photographer and balloonist Gaspard-Felix Tournachon revealed the world from a perspective never seen before: above. As airplanes and then satellites took to the skies and photographic technology improved rapidly during the last century and a half, the black-and-white photos of the early days evolved into the detailed, beautiful and informative microwave, multispectral and hyperspectral “remote sensing” images of today. These images now give much more than a new perspective, they help detect oil spills, determine soil-moisture content, monitor vegetation growth, find mineral ores, observe ocean circulation, find ancient archeological sites, determine how much Earth shifted in an earthquake and so much more. These observations act, to some degree, as the Earth’s physician, monitoring its health and helping to indicate potential paths to sustainability for Earth and its parasite, humans. This talk will explore some of these monitoring systems and what they’re telling us about Earth’s health today.
