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.
