A milestone reached: the tenth CycloPod on www.cyclostratigraphy.org already. This month, we have Jaqueline Ferreira from São Paolo (Brazil) telling us about surprising responses of Brazilian rainfall and ecosystems to astronomical forcing. This podcast is based on her 2022 Quaternary Science Reviews paper. 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....

Our ninth CycloPod on www.cyclostratigraphy.org has Arne Ulfers as our guest (LIAG, Hannover, Germany). Half-precession cycles usually have a low-latitude origin, but can also be observed outside of the tropics. In his 2022 Quaternary Science Reviews paper, Arne figures out how far north half-precession signatures can be distinguished. Spoiler Alert: At Lake Ohrid (North-Macedonia / Albania), they are clearly expressed in lacustrine sediments of the last 1 million years. The Intro music of...

Podcast number 8 on www.cyclostratigraphy.org is by Simin Jin (China University of Geosciences Wuhan). In her 2022 Earth and Planetary Science Letters paper, Simin investigates the most expanded Paleocene - Eocene Thermal Maximum section known to date: a siliciclastic turbidite sequence from the North Sea! 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 seventh podcast on www.cyclostratigraphy.org is the first double-interview! Two new papers came out over the last couple of weeks, discussing the response of ocean productivity to astronomical forcing: Clara Bolton and her colleagues focus on the Pleistocene in Nature, whereas Boris Karatsolis and his team deal with the Mio-Pliocene biogenic bloom (Nature Communications). Their results seem contradicting at first, but this episode of CycloPod reveals that these two geologic time windows...

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...

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...

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...

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...
