    A Tour of the Cryosphere – NASA Goddard Space Flight Center (2009)

    The cryosphere covers parts of the Earth’s surface where water is found in the form of snow, sea ice, glaciers, permafrost, ice sheets, and icebergs. Ice and snow exist close to their melting point. Fluctuations in surface temperatures of our planet leads to frequent state changes in water from solid to liquid and back. Using satellite observations scientists monitor such changes in the global and regional climate. The Earth’s cryosphere shrink and expand on a yearly basis. The animation begins […]

  • Weekly Changes in Arctic Sea Ice Age During 1984 – 2016 – NASA/SVS (2017)

    Weekly Changes in Arctic Sea Ice Age During 1984 – 2016 – NASA/SVS (2017)

    NASA’s Scientific Visualization Studio (SVS) has produced an animation showing the sea ice dynamics in the Arctic. The diminishing ratio of multi-year sea ice is staggering. Human contribution to global warming is well documented. The response of the polar regions to heating especially in the Arctic is extremely fast. While scientists are rushing to predict future temperature and precipitation using exceedingly complex climate models, the behavior of the cryosphere is a curious one. We are already witnessing rather large glacial […]

  • A Day in the Life of an Elite Male Greater Sage-Grouse on the Lek – Marc Dantzker – Cornell Lab of Ornithology (2015)

    A Day in the Life of an Elite Male Greater Sage-Grouse on the Lek – Marc Dantzker – Cornell Lab of Ornithology (2015)

    Here’s another fascinating piece of natural history from the Cornell Lab of Ornithology. In this series of short observations staff producer and biologist Marc Dantzker breaks down the mating behavior and social interaction of the Greater Sage-Grouse (Centrocercus urophasianus) in five sections. Lekking or lek mating is a breeding behavior where males come together in a place and perform competitive displays to impress visiting females. While males do their “hello check me out” dances, females asses their qualities and choose […]

  • A Leafcutter Ant Colony in Barro Colorado Island

    A Leafcutter Ant Colony in Barro Colorado Island

    Filmed on Jan 28th 2017 during the dry season. Smithsonian Tropical Research Institue (STRI) Barro Colorado Island (BCI), Panama. Leafcutter ants are an impressive group with more than 40 different species. All evolved and diversified in the New World at around 12 million years ago. Phylogenetic evidence suggests their evolution could go back as far as 50 million years ago when America separated from Africa. A mature colony can have more than 8 million workers collectively farming a subterranean fungus. […]

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

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

    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)

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

    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)

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

    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 […]

  • Great White Shark Pup off the Northern Aegean Coast of Turkey

    Great White Shark Pup off the Northern Aegean Coast of Turkey

    Be prepared to hear a fascinating piece of natural history about the Mediterranean great white sharks (Carcharodon carcharias). Story is fascinating for multiple reasons. First, great whites are one of the most charismatic, vulnerable, cryptic and misunderstood predator fish species. Second, the story takes place in a quite unexpected location. Altınoluk is a town on the northern Aegean coast of Turkey. It is located to the south of Troy on a legendary sea route known as the Argonaut route where […]

  • Open-air Processional Column Termites in Bukit Timah Nature Preserve, Singapore (2016)

    Open-air Processional Column Termites in Bukit Timah Nature Preserve, Singapore (2016)

    Social insects are a major force in land habitats. A mature leaf-cutter ant colony can consume leaf material equal to a weight of a cow every day. Termites are another insect group (related to cockroaches) evolved independently to achieve sociality. Their effects on ecosystems in terms of material and nutrient cycling can rival those of ants. Higher termites (family Termitidae) feed on a wide variety of plant-based material, including decaying wood, leaf litter, humus, fungi, lichens, dung, and grasses. Non-wood-feeding […]
