    PUBLIC LECTURE: From Plate Tectonics to Deep Earth Dynamics

    46:07

    A Seismological Journey Inside the Earth.
    2016 IRIS/SSA Distinguished Lecturer
    Caroline Beghein, U.C. Los Angeles
    (
    August 29, 2016 at the OMSI Science Pub, Venetian Theater.
    The motion of the tectonic plates that divide the Earth's surface explains many geological features and events - from mountain building, to deep oceanic trenches, to earthquakes, tsunami generation, and the presence of volcanoes. These motions at the surface are driven by processes deeper inside the Earth, in particular by the overturn of the mantle through convection: hot, lighter rocks rise to the surface and cold, denser material sinks. This process causes solid rocks in the mantle to flow and deform over geological time scales. To understand what happens at the surface, we need to study the deep Earth interior. We cannot, however, directly sample rocks from the mantle. Instead, scientists use recordings of the waves generated by earthquakes to map the physical properties of mantle rocks.

    Geology in Space: Meteorites and Cosmic Dust

    1:11:38

    Geology no longer is the study of the Earth. Rocks are found throughout the universe on other planets, asteroids and comets and as debris ranging in size down to the tiniest pieces of stardust.

    In the June London Lecture Matt Genge, a planetary scientist and geologist from Imperial College London, discussed the geology of space, recorded in meteorites and cosmic dust, showing that the principles of geology still hold true far beyond the bounds of our home world.

    What is data? Preserving Earth Science Samples for the Future | lecture by Sarah Ramdeen

    43:08

    On Monday, October 3, 2016, Ms. Sarah Ramdeen, EarthCube Distinguished Lecturer & Early Career Scientist, spoke at LSU.

    What is data? Is it a spreadsheet, a database? What about physical objects like rocks and fossils? Are they data? This talk addressed these concepts and how it applies to data preservation and management policies. It included current initiatives within the information science and earth science communities, and highlighted the role of librarians, information scientists, and archivists in the ‘future proofing’ of earth science data.


    Sarah Ramdeen is a doctoral candidate at the School of Information and Library Science at the University of North Carolina in Chapel Hill. Her research interests include information seeking behavior of earth scientists, the stewardship of earth science data, and physical objects as data. Sarah has a B.S. in Geology and a M.S. in Library and Information Studies, both from Florida State University. She is currently a sea ice annotator on ClearEarth, a NSF funded natural language processing project, and research assistant for a UNC climate study on the advancement of women in academic science and engineering careers.

    Carl Sagan: Christmas Lectures 1 - The Earth as a Planet

    59:49

    1977 Carl Sagan Christmas lectures 1, the earth as a planet.

    In his first Christmas Lecture, American astronomer and cosmologist Carl Sagan explores planet Earth and the place, scale and geometry of the pale blue dot in the Solar System.

    Sagan provides a unique insight into the history of our knowledge of the third planet from the Sun, formed 4.5 billion years ago.

    Using images and models of the planets in our Solar System, Sagan reveals how the heliocentric model of our universe, in which the Earth and planets revolve around the Sun, came to replace the earlier Aristotelian idea that our planet was at the centre and everything orbited around it.

    As the complexity of observational tools has developed from simple telescopes to complex spacecraft, so too has our understanding of the world we inhabit. Looking back on the evolution in space science in the years since Sagan's lectures we have made huge advances in our understanding of our planet's environment, climate, weather, geology and biology -- as well as our relative place in the universe.

    Description: In recent decades we have observed a significant reduction of the cryosphere due to anthropogenic climate change. The observed and predicted changes in the extent and amount of snow and ice will have major impacts on climate, ecosystems and human populations both at a local and global scale. This course will introduce students to the science behind climate change as well as the physical and chemical processes that govern components of the cryosphere, including snow, permafrost, sea ice, glaciers and ice sheets. Particular emphasis will be placed on the important role that each component plays in the larger climate system and potential feedbacks. We will also examine some of the social, economic and political impacts that the melting cryosphere will have on countries around the Arctic and also worldwide, such as access to new petroleum reserves, infrastructure damage due to melting permafrost, sea level rise and decreases in freshwater availability.

    Human Life on Mars

    1:32:37

    Mars is the fourth planet from the Sun and the second smallest planet in the Solar System, after Mercury. Named after the Roman god of war, it is often described as the Red Planet because the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the second highest known mountain within the Solar System (the tallest on a planet), and of Valles Marineris, one of the largest canyons. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Mars trojan.

    Until the first successful Mars flyby in 1965 by Mariner 4, many speculated about the presence of liquid water on the planet's surface. This was based on observed periodic variations in light and dark patches, particularly in the polar latitudes, which appeared to be seas and continents; long, dark striations were interpreted by some as irrigation channels for liquid water. These straight line features were later explained as optical illusions, though geological evidence gathered by unmanned missions suggests that Mars once had large-scale water coverage on its surface at some earlier stage of its life. In 2005, radar data revealed the presence of large quantities of water ice at the poles at mid-latitudes. The Mars rover Spirit sampled chemical compounds containing water molecules in March 2007. The Phoenix lander directly sampled water ice in shallow Martian soil on July 31, 2008]

    Mars is host to seven functioning spacecraft: five in orbit – the Mars Odyssey, Mars Express, Mars Reconnaissance Orbiter, MAVEN and Mars Orbiter Mission – and two on the surface – Mars Exploration Rover Opportunity and the Mars Science Laboratory Curiosity. Defunct spacecraft on the surface include MER-A Spirit and several other inert landers and rovers such as the Phoenix lander, which completed its mission in 2008. Observations by the Mars Reconnaissance Orbiter have revealed possible flowing water during the warmest months on Mars. In 2013, NASA's Curiosity rover discovered that Mars' soil contains between 1.5% and 3% water by mass (about two pints of water per cubic foot or 33 liters per cubic meter, albeit attached to other compounds and thus not freely accessible).

    Mars can easily be seen from Earth with the naked eye, as can its reddish coloring. Its apparent magnitude reaches −3.0, which is surpassed only by Jupiter, Venus, the Moon, and the Sun. Optical ground-based telescopes are typically limited to resolving features about 300 km (186 miles) across when Earth and Mars are closest because of Earth's atmosphere.

    “Dire Predictions: Understanding Climate Change” – the Earth101 lecture

    35:37

    This lecture will begin with a review of the now-solid evidence for a human influence on the climate of recent decades. Such evidence includes instrumental measurements available for the past two centuries, paleoclimate observations spanning more than a millennium, and comparisons of the predictions from computer models with observed patterns of climate change. The lecture will then address future likely impacts of human-induced climate change including possible influences on sea level rise, severe weather, and water supply. The lecture will conclude with a discussion of solutions to the climate change problem. (Note: There is a small problem with the lights in the first three minutes).
