CycloPod

Our first cyclopod of 2024 is another live episode, where we are joined by Pierre Josso, from the BGS at Keyworth, and Tim van Peer, from the University of Leicester. Tune in to hear about their exploits investigating the origins and implications of Milankovitch cyclicity in the Pb-isotope data from an Atlantic deep-sea iron manganese nodule from offshore West Africa (Josso et al., 2021, EPSL). Th...

We are back with our 15th CycloPod Episode! This time we are joined by Anya Crocker, who is a research fellow in Palaeoceanography and Palaeoclimate at the University of Southampton. In this podcast, we hear about Anya's 2022 Nature Geoscience paper looking at astronomically controlled Saharan aridity in the Late Miocene, with surprising insight into how long there has been a desert in this region...

The 14th podcast on cyclostratigraphy.org is by several young researchers: Loic Sablon (Louvain, Belgium), Valentin Jamart (Lausanne, Switzerland), Peng Zhou (Beijing, China), Miho Ishizu (Pusan, South Korea), and Agnese Mannucci (Urbino, Italy). It was recorded during the EGU 2023 meeting and shows the active involvement of many enthusiastic young researchers in the EGU, and that there is no shor...

The 13th podcast on cyclostratigraphy.org is by Mohammad Farhat, a postdoc at IMCCE, Paris Observatory. Mohammad works with Jacques Laskar and the AstroGeo team ( http://www.astrogeo.eu/ ) on refining and extending the orbital and rotational solutions of the Earth into and beyond the Mesozoic. In this podcast, Mohammad discusses the team's recent paper on the tidal evolution of the Earth-Moon syst...

Another milestone: the first live recorded episode of CycloPod! This month, we have Udara Amarathunga from ANU (Canberra) revealing the details about the "mystery sapropel". This podcast is based on his 2022 Nature Geoscience 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...

Anta-Clarisse Sarr is our guest for CycloPod Episode 11 on www.cyclostratigraphy.org . Anta-Clarisse is a postdoc in CEREGE and, there, she used a Earth System Model to study the effect of topography on Miocene monsoon systems ( Sarr et al., 2022 , Nature Geoscience). Her results have major implications for many of the work presented by previous CycloPod interviewees! The Intro music of this podca...

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...

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...

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...

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...

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...

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 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 publis...

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...
