Pangaea
Geophysicist and geologist Tanya Atwater talks about the super continent Pangaea, thought to have broken up into the continents as we know them today beginning about 200 million years ago.
Plate Tectonics and Earthquake Distribution
Geophysicist and geologist Tanya Atwater talks about the correlation between plate boundaries and earthquake distribution.
Plate Tectonics and Heat
Geophysicist and geologist Tanya Atwater talks about plate tectonics as a mechanism by which Earth's interior sheds the tremendous heat that builds up as a result of radioactive decay.
Post-World War II Oceanography
Geophysicist and geologist Tanya Atwater talks about technology developed as part of the war effort in the 1940's that would prove critical in the formulation of plate tectonics theory.
Scattering
Renowned oceanographer and geophysicist Walter Munk talks about scattering, which occurs as sound bounces off bubbles, suspended particles, organisms, the surface, the bottom, or other objects. Small-scale temperature ch..
Sea Level Change Over Time
Renowned oceanographer and geophysicist Walter Munk talks about the rise in sea level since the last Ice Age. Professor Munk notes that the geologic record indicates that sea level has risen by one hundred and twenty met..
Seafloor Spreading and Plate Tectonics (Part 1)
Geophysicist and geologist Tanya Atwater talks about the role of seafloor spreading and spreading centers in the plate tectonics process.
Seafloor Spreading and Plate Tectonics (Part 2)
Geophysicist and geologist Tanya Atwater talks about the Deep Sea Drilling Project and the confirmation of magnetic reversals that provided strong evidence of seafloor spreading and plate tectonics.
Seafloor Spreading: Harry Hess
Geophysicist and geologist Tanya Atwater talks about seafloor spreading, an idea first articulated by Harry Hess that many consider to be the linchpin of plate tectonics.
Seafloor Spreading: Vine and Matthews
Geophysicist and geologist Tanya Atwater talks about work done by Fred Vine and Drummond Matthews that ultimately provided proof of seafloor spreading by tracking the patterns of magnetic striping on the ocean floor.
