Breaching the Frozen Frontier – Studying the Poles via Geospatial Data

With a population that is expected to reach 7 billion in 2011, it is fascinating to contemplate that there are still reaches of the earth where humans have never set foot. However, thanks to the proliferation of satellites and ever-improving satellite imagery, there may come a time when we will have virtually set foot on every part of the earth’s surface. The planet’s poles are prime candidates for exploration via satellite. The harsh climates make physical exploration difficult, dangerous, and expensive. But thanks to advances in GIS technology, scientists of every discipline will have the opportunity to research previously unknown facts on an unimagined scale.

As the Polar Geospatial Center’s geophysicist and team leader Paul Morin explains, "Our work impacts everything from research on the movement of glaciers to the study of penguin colonies to the landing of military aircraft in remote locations." Using advanced sensors with higher resolution has enabled scientists to conduct a whole new slew of experiments, including the first-ever census of emperor penguins. Thanks to satellites such as GeoEye-1, researchers are able to discern individual animals to calculate accurate population numbers. This collaboration to extend mankind’s knowledge of our polar regions extends past the purely scientific. The Polar Geospatial Center is further providing its expertise to the production team of “Frozen Planet”, an upcoming BBC documentary hosted by the peerless David Attenborough.
