Peer feedback

A system will be set up where participants provide friendly and constructive feedback on each others' presentations.

Professional skill development

There will be discourses on topics relevant to early-career researchers. These will include:

- Workshop 1 "How to write a scientific proposal for funding." Presenters: Hubertus Fischer, Jonas Bunikis (European Research Council) and Pilar Calatayud (University of Zaragoza).
- Workshop 2 "How to communicate science." Presenters: Alicia Newton, Liz Kalaugher and Angela Wade
- Workshop 3 "Data" Darrell Kaufman (Data Stewardship Integrative Activity and how it works in practice); Alicia Newton (Nature policy regarding data availability); Jonas Bunikis (the position of the European Research Council on data policy).

Breakout discussions

Participants will discuss and develop strategies on specific topics in small groups, under moderation of a senior scientist. The outcome of the discussion will be presented to the plenary and prepared for publication in the PAGES Magazine.

Publication opportunity

YSM participants will be offered the opportunity to publish their work as full papers in a special issue of Climate of the Past. Some YSM participants will be given the opportunity to join the team of co-guest editors for the special issue.

Social activities

An icebreaker reception is planned for the evening of 7 May, followed by an activity. A dinner is planned for 8 May, followed by another (different) activity. An excursion to Ainsa is planned for 9 May, before participants take the bus back to Zaragoza to join the OSM Icebreaker Party.
