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

    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 […]

  • Albatross Nest Live from Hawaii

    Albatross Nest Live from Hawaii

    If you see a dark screen, bear in mind that it might be night time in Hawaii. Breeding season 2016 has ended happily. See y’all in 2017! Welcome to an Laysan Albatross (Phoebastria immutabilis) nest from the island of Kauai, geologically the oldest island of the Hawaiian archipelago. The webcam is operated by the Bird Lab of Cornell University. The Laysan Albatross gets its name from its Laysan breeding colony in the Northwestern Hawaiian Islands, where it is the second […]

  • 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. […]

    Rosie – Hummingbird Nest Cam – Live from La Verne, CA

    2016-2017 breeding season has started! IF YOU SEE a BLACK SCREEN please WAIT until SUNRISE in CALIFORNIA! Rosie is sleeping 🙂 Welcome to the busy and productive nest of the hummingbird called Rosie from La Verne, southern California located on a branch of a fig tree. Allen’s hummingbirds on average have their breeding season between February and July. Studies done on ringed hummingbirds have shown that they can live up to 12 years. According to Karl Schuchmann, an ornithologist at […]
