In 2022 we finally had an in-person COSIMA workshop! 🎉 Thanks to everyone who attended and made it such an enjoyable and productive meeting.
Dates
9am Thursday 3rd Nov – 4pm Friday 4th Nov 2022
Location
Beautiful Hobart! (specifically, CSIRO Hobart Auditorium, Castray Esplanade, Battery Point)
Scope
The workshop featured our usual mix of talks and discussions, covering physical oceanography, sea ice, biogeochemistry, waves, model development and technical advances. Our workshops are not restricted to ACCESS-OM2 users – we welcome contributions from all who consider themselves part of the COSIMA community (but if you haven’t already, please sign up to our COSIMA-announce email list). Reports and slides from previous workshops are available here.
Program
The latest version of the workshop program was COSIMA2022_workshop_program_2022_10_28.pdf.
Discussion topics
Breakout sessions on Thursday afternoon. Please follow the links to continue these discussions!
1. Priorities for large CPU experiments (Chair: Andrew Kiss)
2. Vision for WOMBAT ocean BGC (Chair: Matthew Chamberlain)
3. COSIMA recipes / on-ramping for new people (Chair: Julia Neme)
