Our transcription: In 1930, Alfred Wegener died of a heart attack while attempting to cross the Greenland Ice Cap.
By the 1940s with a lack of any conclusive evidence, the heated arguments about continental drift cooled off.
Wegener's Theory, however, would soon, once again, be propelled to the forefront of scientific debate but in a most unexpected way.
In order to understand continental drift, we really needed to know how the oceans are made and destroyed.
We had very little understanding at all even of the shape of the sea floor, and so we really needed some new technology.
Oceanography ventures are very driven by technology, and it turns out-- I hate to admit anything was good about World War II, but it was very good for developing new technologies.
