Vine's work, with that of Drummond Matthews and Lawrence Morley of the Geological Survey of Canada, helped put the variations in the magnetic properties of the ocean crust into context in what is now known as the Vine–Matthews–Morley hypothesis.

The Morley–Vine–Matthews hypothesis was the first key scientific test of the seafloor spreading theory of continental drift.
Continental drift
1 linksHypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed.

The best explanation was the "conveyor belt" or Vine–Matthews–Morley hypothesis.

Confirmation of the Earth's polarity reversals a few years later not only further validated the Vine–Matthews–Morley hypothesis but provided a timescale allowing the rate of spreading to be estimated for each section of ocean ridge.

His measurements of magnetic anomalies on the ocean floor supported the Morley–Vine–Matthews hypothesis explaining seafloor spreading.
