CycloPod
Season 1
Episode 6: Margriet Lantink
by David De Vleeschouwer
The sixth podcast on www.cyclostratigraphy.org is by Margriet Lantink. In her 2019 Nature Geoscience paper, Margriet demonstrated a climate control on Banded Iron Formations from South Africa. In this podcast, she elucidates how cyclostratigraphy and radio-isotopic dating were both essential in coming to her interpretation. She also shares her vision on what's next in researching the early days of Planet Earth. The Intro music of this podcast is again an excerpt of a piece based on the North Atlantic Oscillation from the "Aphrodite's Dew" book and CD project by Arvid Tomayko and Sandro Montanari.

The fifth podcast on www.cyclostratigraphy.org is by Anna Joy Drury. She talks about a 30 million year long carbonate content and stable isotope record that she compiled for an ocean drilling site on Walvis Ridge, in the South-East Atlantic Ocean. In this podcast, Anna Joy discusses how climate and carbon cycle have been responding to astronomical frocing throughout the late Cenozoic. This discussion is based on scientific results, recently published in Climate of the Past. They also discuss how CODD, or Code for Ocean Drilling Data (Wilkens et al., 2017), was used to construct composite core images of the sedimentary sequence. The Intro music of this podcast is again an excerpt of a piece based on the North Atlantic Oscillation from the "Aphrodite's Dew" book and CD project by Arvid Tomayko and Sandro Montanari.

The fourth podcast on www.cyclostratigraphy.org is by Zhixiang Wang. He talks about the Late Miocene sedimentary response to astronomical forcing in North-East Tibet. In this podcast, the reasons why an eolian sequence displays a completely different astronomical signature compared to a contemporaneous lacustrine section are explored. This discussion is based on scientific results, recently published in GSA Bulletin. The Intro music of this podcast is an excerpt of a piece based on the North Atlantic Oscillation from the "Aphrodite's Dew" book and CD project by Arvid Tomayko and Sandro Montanari.

The third podcast on www.cyclostratigraphy.org is by Rocío Paola Caballero-Gill. She is a cyclostratigrapher who co-founded the GeoLatinas. During this podcast, she talks about her earlier work on Pliocene climate and stratigraphy, about her new paper on being anti-racist in geoscience (Ali et al., 2021), and about CycloAstro and CycloCohort. The Intro music of this podcast is again an excerpt of a piece based on the North Atlantic Oscillation from the "Aphrodite's Dew" book and CD project by Arvid Tomayko and Sandro Montanari.
