The EGU General Assembly 2023 brings together geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary, and space sciences. The EGU aims to provide a forum where scientists, especially early career researchers, can present their work and discuss their ideas with experts in all fields of geoscience.

Abstract submission is open until 10 January 2023.

Goal: CliC grants aim at increasing the engagement of Early Career Scientists in CliC. The project strives for gender balance and geographical diversity so submissions from regions currently under represented in CliC, such as Asia and Africa, are particularly encouraged.

Objectives: Applications shall target CliC´s vision and mission as described in the Strategic Plan 2022-2031, as well as to address one or more of its five strategic areas, as follows: 

1. Engagement of a broad and diverse community in cryosphere research
2. Cryosphere ice loss- assessment and impacts
3. Projection of future ice loss and impacts
4. System description of the cryosphere regions
5. Knowledge syntheses and communication to stakeholders

Timeline: Activities must be completed within one year after the project´s acceptance unless otherwise outlined in the proposal.

Who can apply:

• Early Career Scientist: students enrolled in a PhD programme and scientists who have obtained a PhD within 7 years by 1 March 2023. The period excludes career breaks due to parental leave, health issues, etc.
• For research visits: the visiting institution must differ from the applicant´s country of origin and current country of residence.

Submission deadline: 1 March 2023 at 23:59 /11:59 pm UTC
