GEUS Bulletin An open access, peer-reviewed geoscience journal published by the Geological Survey of Denmark and Greenland.

@evangowan.bsky.social Interesting to hear about the #DiamondOpenAccess GEUS Bulletin (geusbulletin.org), I was not aware of this option. "Platform for Earth Science research and data published in Denmark, Greenland and the wider Arctic", sounds good! 👍

IGS Global Seminar: Ralf Greve | February 18 Topic: Basal sliding laws and flow laws for ice-sheet and glacier modelling, and why their non-dimensionalization can make modellers' lives easier

Join me at the @igsoc.bsky.social Global Seminar ❄️ on Feb 18 (20:00 UTC). I'll be talking about basal sliding laws, flow laws, and how their non-dimensionalization simplifies #Glacier and #IceSheet #Modelling. 📉🧊

👏👏👏
That's the way to move forward with #AcademicPublishing: community-organized, free for readers & authors. I would love to see such an initiative in #Glaciology / #CryosphereSciences as well.

No free labour for a multi-million bucks industry!

I have made it a personal policy not to do unpaid work for commercial, for-profit publishers anymore. So, #SpringerNature, #Elsevier et al., if you'd like me to review your papers, you'll have to pay me. Otherwise, no deal.
