Antoine Nasser and Alistair Adcroft investigate how machine learning can be used to develop **stable and accurate numerical schemes for solving the linear advection equation**. Their **[study](https://doi.org/10.48550/arXiv.2606.17497)** identifies the key factors governing the performance of data-driven finite-volume methods, including network architecture, training data, and normalization strategies. They show that data-driven reconstructions based on cell averages are shape-specific, limiting their ability to generalize across different classes of solutions. They introduce a machine-learned flux limiter that improves shape preservation relative to widely used classical schemes and demonstrate that training on polynomial profiles yields stable, high-order accurate discretizations. Overall, the work provides **practical guidelines for designing robust and generalizable machine-learning-based numerical methods for scientific computing.**

Yuan Yuan and collaborators from M²LInES and Open Athena have unveiled **[Samudra 2](https://doi.org/10.48550/arXiv.2606.02610)**, a next-generation neural ocean emulator that collapses massive supercomputer workloads down to a single GPU. Running **100x to 1000x faster** than traditional numerical models, it successfully scales to fine resolutions capable of capturing critical mesoscale eddies and sharp currents like the Gulf Stream without drifting or "blowing up" over multi-year simulations.



By slashing deep-ocean errors by **7–10×** and maintaining realistic physics, Samudra 2 turns a major computational bottleneck into an opportunity for massive ensemble modeling. This open-source breakthrough shifts climate science from rationing a few scenarios to running hundreds of plausible futures, paving the way for low-cost, decision-grade forecasting in shipping, energy, and sea-level rise. Read the full announcement in our **[latest blog post](https://medium.com/@lz1955/samudra-2-a-fast-cheap-ai-ocean-model-now-at-the-scale-that-matters-b37883c62d51)**, explore the **[project page and rollout demo](https://m2lines.github.io/Samudra/docs/)**, grab the **[code on GitHub](https://github.com/m2lines/Samudra)**, or just run it **using the weights on [Hugging Face](https://huggingface.co/M2LInES/Samudra2)**.
