Introduction
Eystein Jansen, born on February 28, 1953, is a prominent Norwegian geologist specializing in marine geology and paleoceanography. He holds a professorship at the University of Bergen and has made significant contributions to the field of climate research through his work as a researcher and former Director of the Bjerknes Centre for Climate Research (BCCR). His leadership extends beyond national boundaries, as he serves as the vice-president of the European Research Council (ERC), overseeing the EU’s commitment to basic research in physical sciences and engineering. Jansen’s academic journey and research endeavors have positioned him as a leading figure in understanding the complex relationship between ocean dynamics and climate change, particularly in relation to ice sheet formation and retreat.
Academic Background
Jansen’s academic path began at the University of Bergen, where he earned his MSc degree in paleoceanography in 1981. His education continued with a PhD, completed in 1984, focusing on “Late Weichselian paleoceanography in the Nordic Seas.” This thesis laid the foundation for his future research, emphasizing the historical shifts in oceanic conditions during geological transitions. Following his doctoral studies, Jansen was appointed as a researcher at the National Laboratory for light stable isotope geochemistry at the University of Bergen. Established in 1983, this laboratory became a pivotal point in Jansen’s career, facilitating collaborations with esteemed scientists globally, particularly in paleoclimatology. One of the most influential figures in his early career was Nicholas Shackleton from the University of Cambridge, whose mentorship helped shape Jansen’s approach to research.
Professional Career
In 1985, Jansen transitioned into academia as a tenured associate professor at the University of Bergen. His dedication and expertise were recognized with a promotion to full professor in 1993. Over his career, he has authored approximately 200 scientific papers that explore the intricate links between ocean circulation and climate change. His research primarily focuses on Arctic and sub-Arctic regions but also includes studies of southern oceans and tropical areas. Utilizing geochemical and sedimentological techniques on ocean sediments, Jansen has participated actively in various international research programs, including the Ocean Drilling Program and multiple expeditions on Norwegian vessels.
Research Contributions
Jansen’s work is characterized by its integrative approach to studying past climate events through oceanic data. His significant contributions to understanding abrupt climate change were recognized with an ERC Synergy Grant (ice2ice) awarded in 2014, enabling collaboration with other principal investigators to delve deeper into this critical area of research. Under his leadership, the Bjerknes Centre for Climate Research was inaugurated in 2000, evolving into a major hub for climate science until 2013 when he stepped down as Director. The Centre received accolades from the Norwegian Research Council, achieving status as a Norwegian Centre of Excellence shortly after its founding.
Leadership Roles and Affiliations
Eystein Jansen holds several influential positions within various scientific communities. He is a member of the Scientific Council of the European Research Council (ERC), contributing to strategic decisions regarding funding and direction for scientific research across Europe. Additionally, he serves as the Academic Director of the Academia Europaea Bergen Knowledge Hub and leads the Geoscience group within the Norwegian Academy of Science and Letters.
SapienCE Centre
In 2017, he became co-director of the SapienCE Centre, another Norwegian Centre of Excellence recognized by the Norwegian Research Council. This multidisciplinary initiative integrates archaeology with climate science and cognitive neuroscience to study the emergence of modern behavior among Homo sapiens in Southern Africa during approximately 120,000 to 50,000 years ago. This innovative approach highlights Jansen’s commitment to expanding interdisciplinary research to understand humanity’s past better.
Contributions to Climate Reports
Jansen’s expertise extends to influential international assessments of climate science. He played a crucial role as a co-ordinating lead author for the paleoclimate chapter of the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report. His involvement did not end there; he continued to contribute significantly to the IPCC Fifth Assessment Report as one of its lead authors. These reports are critical components in shaping global policy discussions surrounding climate change and have helped inform international responses to environmental challenges.
Awards and Recognitions
Throughout his distinguished career, Eystein Jansen has been recognized with numerous awards reflecting his contributions to geology and climate science. In 2019 alone, he received both the Meltzer Prize for excellence in research and the Brøgger Prize for lifelong achievements in geological sciences. His memberships in esteemed learned societies further underscore his standing within the scientific community; these include being inducted into Academia Europaea in 2012, joining the Norwegian Academy of Science and Letters in 1998, becoming a member of the Norwegian Academy of Technological Sciences in 2005, and being recognized by the Norwegian Scientific Academy for Polar Research in 2007.
Conclusion
Eystein Jansen’s career is marked by significant achievements that span several decades in marine geology and paleoceanography. His academic contributions have provided valuable insights into how ocean circulation impacts climate systems over time—an understanding increasingly vital in addressing contemporary climate issues. As a leader at various prestigious institutions and an active participant in key international assessments like those conducted by the IPCC, Jansen exemplifies dedication both to research excellence and public engagement with science. His efforts not only enhance our comprehension of Earth’s climatic history but also influence current scientific practices and policies aimed at mitigating climate change effects.
