The 1st TranSEHA Young Researchers Seminar Held at the Institute for Space-Earth Environmental Research, Nagoya University
On Wednesday, July 9, 2025, the 1st TranSEHA Young Researchers Seminar was held in Room 221 of the Research Institutes Building II at Nagoya University.
The purpose of this seminar series is to foster mutual understanding among early-career members engaged in building a transdisciplinary network, with regard to each other's research fields, themes, directions, and challenges—ultimately aiming to facilitate collaborative research and joint problem-setting.
The theme of this first seminar was “Carbon-14”. Lectures covered the fundamental principles and measurement methods of 14C, 14C calibration, and 14C studies using tree rings, as well as the principles and analytical methods of oxygen isotopes. In addition, early-carrer researchers presented their own research.
The seminar featured many insightful questions from those outside the specific field, providing a valuable opportunity for learning and laying the foundation for building a future transdisciplinary research network.
The 2nd seminar is scheduled to take place at Okayama University of Science from October 14 to 17, focusing on the theme “Archaeomagnetism.”
