ICYS seminar series

ICYS hosts an international ice-core seminar series which started in 2021, with the support of the International Partnership in Ice Core Sciences (IPICS).

ICYS holds monthly seminars with two talks – one from a senior researcher, followed by an early-career researcher (ECR) in a similar research theme.

There is plenty of time for questions and discussion.

Organizers feel that this is be a good way to bring together international ice-core-related research.

The series aims to provide much needed scientific interactions between researchers at all stages in their careers, especially given the cancellation of in-person conferences at this time.


Upcoming Seminar

To be announced as soon as possible.
