Episode 5 - Daniel Ariztegui

We close the first season of Into the Core with a guest who has left us with meaningful reflections and valuable lessons. This final episode is both nostalgic and inspiring, offering Early Career Researchers a different perspective on our role not only as scientists, but also as people. This includes your team as a family, the importance of living in the present and the need for work-life balance. Flavio Anselmetti is a scientist at the University of Bern in Switzerland. He began his career as a marine geologist and later became involved in research on paleoclimate, geohazards, and paleoseismology in lakes. He has participated in several ICDP projects, including the Lake Petén Itzá drilling project in Guatemala. With more than 30 years of field experience, Flavio shares not only funny stories from scientific campaigns but also personal experiences and lessons that science has taught him throughout his career.Turn up the volume and enjoy these stories and much more in the final episode of Into the Core First Season.Hosts: Rodrigo Martínez-Abarca and Romina AchagaGuest: Flavio Anselmetti Into the Core is supported by the International Continental Scientific Drilling Program (ICDP) and is an initiative of the Early Career Researchers Network.

Almost at the end of the season! In the ninth episode of Into the Core, we talk with Simona Pierdominici, a member of the ICDP Operational Support Group hosted at GFZ in Germany. She is an expert in borehole logging and has participated in several projects of the International Continental Scientific Drilling Program (ICDP).In this episode, our team asks Simona about her field experiences and her beginnings within ICDP projects. Can you imagine celebrating a birthday party in Antarctica or getting lost in the endless white landscape surrounded only by ice?Turn up the volume and enjoy these stories and much more in this new episode of Into the Core.Hosts: Rodrigo Martínez-Abarca and Romina AchagaGuest: Simona PierdominiciInto the Core is supported by the International Continental Scientific Drilling Program (ICDP) and is an initiative of the Early Career Researchers Network.

In the eighth episode of Into the Core, we talk with Arne Ulfers, a researcher at the LIAG – Institute for Applied Geophysics in Germany. He is an expert in borehole logging, with experience in several projects of the International Continental Scientific Drilling Program (ICDP).In this episode, Arne explains how these techniques help us identify and characterize the sediments and rocks beneath a region, allowing scientists to better understand their properties and geometry for a wide range of applications.We also hear memorable field stories, from his arrival in Antarctica as part of the SWAIS2C project to the time he found himself caught in the middle of a storm on Lake Nam Co (Tibetan Plateau), more than 30 km from the shore and at over 4,700 meters above sea level.Curious to know how he made it through?

The Into the Core team returns once again to the IPA-IAL conference in Aix-les-Bains for this seventh episode, where we sit down with Maarten Van Daele.In this episode, we explore how sediments can be key to understanding past events such as paleotsunamis and paleoearthquakes. We also talk about Maarten’s experience during the ICDP Lake Challa drilling campaign and share some memorable field stories — including the time he and his team lost the platform’s floats while drilling a lake in Chile.Curious to know how they solved it? Join us to find out.Maarten Van Daele is an associate professor at Ghent University in Belgium, specializing in sedimentology, geohazards, and limnogeology. His research focuses on lake and marine sediment archives, particularly turbidites as records of past earthquakes, tsunamis, and other extreme events. He is involved in ICDP projects such as DeepCHALLA. In addition, he has worked on unique sites like Iceberg Lake in Alaska, which drained in 1999 through an outburst flood, exposing sedimentary deposits that allow the study of historical earthquakes and other past events in outcrops.Host: Rodrigo Martínez-AbarcaGuest: Maarten Van DaeleEdition: Romina AchagaInto the Core is supported by the International Continental Scientific Drilling Program (ICDP) and is an initiative of the Early Career Researchers Network.

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.Hosts: Rodrigo Martínez-Abarca and Romina AchagaGuest: Jonathan Obrist-FarnerInto the Core is supported by the International Continental Scientific Drilling Program (ICDP) and is an initiative of the Early Career Researchers Network.

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.Host: Rodrigo Martínez-AbarcaGuest: Daniel Ariztegui"Into the Core" is supported by the International Continental Drilling Program (ICDP) and an initiative of the Early Career Researchers Network.

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.Host: Rodrigo Martínez-AbarcaEdition: Romina AchagaStarring: Liseth Pérez Alvarado"Into the Core" is supported by the International Continental Scientific Drilling Program (ICDP) and an initiative of the Early Career Researchers Network.
