    The Day The Mesozoic Died HHMI – Sean B. Carroll (2012)

    This is one of the four educational video series by Sean B. Carroll produced for communicating evolution to public with the support of HHMI. Today we know the cause of the disappearance of the dinosaurs at the end of the Cretaceous period. This knowledge was produced by the meticulous coordinated work of many scientists. The Day The Mesozoic Died focuses on how scientists do the detective work using the scientific method. The discovery that an asteroid struck the Earth 66 […]

  • Perpetual Ocean from NASA

    Perpetual Ocean from NASA

    Understanding large-scale global climate and local weather patterns is important. Majority of our planet is covered by oceans therefore understanding ocean dynamics is key for making climatic forecasts. Here you can watch four interrelated animations produced by NASA’s Scientific Visualization Studio in a single video. All animations are based on simulations of high resolution satellite data on an impressively realistic General Circulation Model (GCMs) that NASA uses called ECCO2 (Estimating the Circulation and Climate of the Ocean Phase II). These […]

    Evolution Timeline (John Kyrk)

    [This video has no sound] Timelines are useful organizing tools to facilitate learning of highly detailed linked processes. The interactive timeline provides a gateway to understand one of the most progressive concepts in recent human history: Evolution. This screen capture video makes a quick introductory summary of cosmological, geological and biological evolution. Significant events since the very beginning of our universe are demonstrated in a chronological order. Evolutionary timeline by John Kyrk is a collaborative effort. Interactive website is constantly […]

    Rosetta Mission to Comet 67/P – Exploratorium (2015)

    Paul Doherty of the Exploratorium explains phases of the European Space Agency’s Rosetta Mission to the comet 67P/Churyumov–Gerasimenko in exquisite detail. Comets are extremely interesting celestial objects. They may have even played role in jump starting life on our planet. When and how chemistry became biology is a burning question for everyone. There has been a period way in the past during the early times of the Earth when meteorites and comets bombarded its surface. This period is known as […]

  • Global Aerosol and Dust Dynamics – NASA SVS

    Global Aerosol and Dust Dynamics – NASA SVS

    The main video featured above consists of three interrelated parts produced separately by NASA’s Scientific Visualization Studio (SVS) which has been producing highly engaging visualizations based on actual and simulated data about global processes running our planet. First narrated visualization shows transport of dust from the Africa to South America between 2007-2013 where the Sahara desert is the source and the tropical Amazon basin is the sink. The scale of interaction between the driest and the wettest places on earth […]

  • Aerosols and Cloud Formation – NASA/SVS

    Aerosols and Cloud Formation – NASA/SVS

    When and where clouds form are important for climate science. Long-term observations have shown that at any given time less than 10 percent of the Earth’s skies are clear with no clouds. We most certainly want to know what is going on in the major 90 percent fraction covered with clouds of some type. Some clouds reflect the sun’s radiation while others trap outgoing heat that would otherwise be emitted to space. Tiny solid and liquid particles suspended in the […]

  • Acid Test – Natural Resources Defense Council (2009)

    Acid Test – Natural Resources Defense Council (2009)

    Since the beginning of the industrial revolution a quarter of the carbon that has been released into the atmosphere was absorbed by the oceans. As a result the acidity of the oceans has increased by %30. Increasing acidity makes it corrosive dissolving the calcium shells of marine organisms. Among them are planktons, corals and pteropods which form the base of the food web. Carbon dioxide dissolves higher quantities in cold water, therefore first biological signs of acidification is observed closer […]

    Chasing El Niño – Carol L. Fleisher – PBS NOVA (1998)

    Can we predict El Niño? Moreover can we calculate it’s severity and effects on different parts of the world? On board the research ship Ka’imimoana scientists carry out measurements and then build computer models to understand the climate cycle that produces El Niño. The documentary “Chasing El Niño” was released by the aftermath of an intense El Niño event observed during 1997/1998 measured. In March 2015 climatologists have started to detect early signs of another one beginning to develop. They […]

  • Voyage of Darwin’s Beagle – Episode 4: The Final Countdown (2009)

    Voyage of Darwin’s Beagle – Episode 4: The Final Countdown (2009)

    “In the wake of Beagle” series brings back the adventure/science mix documentary programs reminiscent of those of Cousteau. Expeditions carried out on a ship and underwater filming was a signature in Cousteau’s filmmaking. This episode prepares the audience for the next episode filmed in the Galapagos Islands. Darwin developed his insight towards evolving species in that volcanic archipelago. Galapagos islands are largely affected by long-term seasonal fluctuations that known as El Nino/La Nina cycle. A few events Darwin witnessed in […]

    Voyage of Darwin’s Beagle – Episode 5: The Paradise of Competition (2009)

    The Galapagos islands has been a pivotal single location where everything came together in Darwin’s mind. The geology of the archipelago and almost every species (Tortoises, iguanas, finches) he observed on each island showed significant variation. The Galapagos Islands, which are part of Ecuador are about 1000 km (620 miles) west of South America. As the three craters on the largest island (Isabela Island) suggest, the archipelago was created by volcanic eruptions. Each year roughly 60,000 tourists visit these islands. […]

    Voyage of Darwin’s Beagle – Episode 6: Toolbox of Survival (2009)

    In Australia the arrival of Europeans profoundly effected the biology of the continent through introduction of non-native species that are reproducing and invading at an unprecedented rate. Australian biologists call it “extinction calamity” since the continent has lost one in ten of its native mammals species in the past 200 years. The effects of climate change is also evident with severe droughts and wild fires. A large fraction of Australian vegetation is serotinous that is adapted to disperse their seeds […]

    Voyage of Darwin’s Beagle – Episode 8: The Ruins of Progress (2009)

    In this last episode of the series the crew of Stad Amsterdam visits Mauritius island before making a final stop in South Africa where the journey of modern Human ancestors began 200 thousand years ago. San culture in South Africa is the most ancestral Human population finding Like many island ecosystems Mauritius has been impacted by introduced species such as macaques. Species evolved on island systems are more prone to extinction. The flightless bird the Dodo is the icon of […]

  • Horseshoe Crabs Mating in Maine

    Horseshoe Crabs Mating in Maine

    This is a quite rare footage of Atlantic horseshoe crabs (Limulus poyphemus) recorded during high tide about 10:00 am in Recompence Shore, Freeport Maine on May 26th 2010. Mating mostly happens in moonlit nights (romantic animals) on sandy beaches. Here they are mating in broad daylight on a rough pebble beach. External fertilization is one of the ancestral ways to produce offspring however it can be rather costly. Egg production requires more resources compared to sperm. Females therefore need more […]
