Nothing says "our publishing model is feeling the heat" quite like SpringerNature buying YouTube ad space. 📺 It looks like a clear reaction to the growing momentum of the #OpenAccess movement. The landscape is definitely changing. 🔓👍 #AcademicPublishing #ScolarlyPublishing #OpenScience

New preprint, submitted to @igsoc.bsky.social Journal of #Glaciology: "The Smith-Morland flow law revisited". We offer a singularity-free alternative to Nye-Glen, avoiding the infinite-viscosity limit at zero stress. Already implemented in #SICOPOLIS. 👉 Zenodo doi.org/10.5281/zeno...

@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! 👍 #ScientificPublishing #ScolarlyPublishing

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. 📉🧊 👉 Details: www.igsoc.org/event/igs-gl... 👉 Paper: doi.org/10.1017/jog....

Release SICOPOLIS v25.12 (2025-12-29) · sicopolis/sicopolis

Main new features Repository migrated from AWI GitLab to GitHub. Rate factor and sliding coefficient made dimensionless; thus decoupled from the exponents of the flow law and sliding law, respecti...

👏👏👏 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. #ScientificPublishing #ScolarlyPublishing #DiamondOpenAccess

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. #AcademicPublishing #ScientificPublishing #ScholarlyPublishing #PeerReview

No free labour for a multi-million bucks industry!

New paper: Introducing dimensionless sliding & flow laws for ice sheets & glaciers, decoupling coefficients from exponents. This makes sensitivity studies and ensemble modelling far simpler. Demonstrated in #SICOPOLIS. ❄️📘 doi.org/10.1017/jog.... [Accidentally deleted, thus reposting; sorry...]
