  Ecology from the Air – Greg Asner (2009) TED Talk

  January 30, 2017 at 1:44 am / Ecological Documentaries, Global Patterns, Video

  Being able to measure interaction of the living and the non-living at large continental-scales is eye opening. That’s what successful scientist Greg Asner does with the Carnegie Airborne Observatory (CAO). NASA’s Landsat earth observation satellites have been feeding us invaluable global-scale data for more than 40 years. The new satellite Landsat 8 began transmitting near-realtime information. Thanks to these earth observation satellites we can instantly know scale of natural or human-made impacts on ecosystems. Deforestation for oil palm plantations in […]

  The Navigators / Pathfinders of the Pacific – Sanford Low and Boyd Estus (1983)

  January 25, 2017 at 9:05 am / Human Nature, Video

  Navigation on the open ocean has been a grand challenge for Humanity. Vikings used Icelandic feldspar chrystals called sunstones enabling detection of the direction of the sun through polarizing light. Chinese used magnetic compass. Calculation of the longitude was an immense problem. Celestial objects have been used by almost all seafarers globally. Polinesians mastered the star compass technique and carried it to a new level in Human history. “The Navigators” was co-directed by Sam Low and Boyd Estus covering the […]

  Geological History of the Continents/Paleomap Project – Christopher Scotese (2015)

  January 5, 2017 at 9:28 pm / Evolution, Global Patterns, Video

  Geology and biological evolution of life are inseparable. More than half of the minerals now incorporated into the upper crust of our planet were produced by living organisms. The movement of continental plates has played a fundamental role in the recycling of mineral resources by the biosphere. Scientists now predict that tectonic activity may have been one of the prerequisites for the origin of life. The acceptance of continental drift by the scientific community and how it affected Earth’s history […]
