Marine Geology podcasts

The Science Show examines mineral nodules formed around fossil shark teeth on the deep-sea floor and the ecological risks of exploiting them. The programme also considers plant responses to climate change, debates over introduced species, and the contributions and limitations of three influential scientists.

Nature staff revisit the landmark cloning of Dolly the sheep from an adult cell and discuss the first direct observation of ocean-floor crust being created.

Esther Sumner describes direct observations of turbidity currents and the challenge of instrumenting active submarine canyons. Smart boulders and acoustic current measurements reveal how these large, long-lasting underwater flows transport sediment. The discussion includes an underwater robot’s accidental encounter with an active current in California’s Mendocino Canyon.
