We kick off the second half of the first season of Into the Core with this sixth episode, featuring Jonathan Obrist-Farner.

In this conversation, our team explores Jonathan’s unique journey — from his early studies in psychology to his transition into geosciences, a path that has led him to propose his first ICDP project. The episode also includes a heartfelt tribute to Andy Cohen, whose legacy we honor and remember.

But the journey hasn’t always been easy. Jonathan shares challenging field experiences, including the demanding work of walking more than 6 kilometers multiple times a day to help build a drilling platform in the lakes of Guatemala.

Curious to hear more about this amazing story? Join us for this inspiring episode.

Jonathan is an assistant professor at Missouri University of Science and Technology (Missouri S&T), originally from Guatemala. He is a geologist and geophysicist with a background in psychology, and the Principal Investigator of the recently approved ICDP project LIBRE (Lake Izabal Basin). His research focuses on sedimentology, stratigraphy, and paleoclimatology, with a particular interest in the evolution of sedimentary basins and the tectonic, climatic, and anthropogenic controls that shape them.

The Into the Core team continues recording in Aix-les-Bains, interviewing scientists involved in ICDP projects.

In this fifth episode, Daniel Ariztegui shares stories and lessons from his years of experience in scientific drilling — including the time he had to meet with royalty to request permission to drill, only to be told: “Do not touch the lake water.”

Curious how they managed to solve it? Join us to find out.

Daniel is an Argentine researcher currently based in Switzerland. His work focuses on sedimentology of drill cores and includes experience in seismic analysis and geochemical proxies, such as organic matter isotopes, to reconstruct past environmental and climate changes.

We continue recording from IPA-IAL 2025 in Aix-les-Bains for the fourth episode of Into the Core. This time, we are joined by Liseth Pérez Alvarado, a senior scientist originally from Guatemala and currently based in Kiel, Germany.

Liseth investigates the clues that ostracods — small crustaceans living in the water column — leave behind in lacustrine and marine sediments. She has been involved in several ICDP projects, including MexiDrill Chalco in Mexico, Lake Petén Itzá in Guatemala, and the upcoming Lake Izabal drilling project.

In this episode, we talk about her field experiences, her scientific journey, and some unforgettable stories from her student days — including the time she lost a boat engine during fieldwork.

In this third episode of Into the Core, the team records live from the IPA-IAL 2025 conference in Aix-les-Bains, France, where we ask scientists to share their funniest field stories.

Our first guest at the conference comes all the way from Spain: Blas Valero, researcher at the Instituto Pirenaico de Ecología in Zaragoza. A sedimentologist, paleoclimatologist, and passionate science communicator, Blas shares some of the unusual traditions he and his team carry out after completing a lake-drilling campaign.

In the second episode of Into the Core, we are joined by someone very special — the driving force behind this podcast and a scientist pushing the boundaries of proxy development in paleolimnology.
Dr. Marta Marchegiano, researcher at the University of Granada, shares unforgettable moments from the field, including an unexpected explosion during a campaign.
Join us for a conversation full of science, stories, and inspiration.

To kick off this podcast, we have a very special guest. Professor Dr. Mark Brenner is a researcher with many years of experience in paleoclimatology and paleolimnology, and is involved in various ICDP projects. While many of us know him for his career, in this episode, we will delve into his experiences in the field, in science, and hear about his learnings in a long academic life.

Welcome to Into the Core, a podcast by the Early Career Researchers Network of the International Continental Scientific Drilling Program (ICDP). Throughout its first season, we talk with ten extraordinary scientists involved in ICDP projects who share funny stories from the field, as well as the lessons and experiences that have shaped their scientific careers.
