On this week’s show: Shark tags to measure ocean deoxygenation, and zircons and the chemistry of early Earth
First up this week: using sharks to measure ocean deoxygenation. Contributing Correspondent Warren Cornwall joins us to talk about a group of researchers putting data logging tags on sharks in order to study how climate change is affecting oxygen levels in some of the ocean’s darkest depths.
Next up, what can 4-billion-year-old minerals teach us about chemistry on early Earth? Producer Meagan Cantwell talks to geochemist Dustin Trail about using minerals called zircons to deduce the chemical properties of the early hydrothermal pools where life began.
This week’s episode was produced with help from Podigy.
