Hi everybody!

Our team at Earthmover is excited to announce a brand new open source project called **Icechunk**. Here’s our launch blog post:

> **[Announcing Icechunk! | Earthmover](https://earthmover.io/blog/icechunk)**
>
> Icechunk is a brand new open-source transactional storage engine for tensor / ND-array data designed for use on cloud object storage.
> Icechunk works together with Zarr, augmenting the Zarr core data model with features that enhance performance,...

Icechunk is an open-source library and specification for the storage of multidimensional array (a.k.a. tensor) data in cloud object storage. Icechunk works together with [Zarr](https://zarr.dev/), augmenting the Zarr core data model with features that enhance performance, collaboration, and safety in a multi-user cloud-computing context. With the release of Icechunk, powerful capabilities such as isolated transactions and time travel, which were previously only available to Earthmover customers via our [Arraylake](https://docs.earthmover.io/) platform, are now free and open source.

We’re super excited to get feedback on Icechunk from the Pangeo community.

You can learn more about Icechunk on the docs page:

> **[Icechunk](https://icechunk.io/)**
>
> Open-source, cloud-native transactional tensor storage engine

and on GitHub

> **[GitHub - earth-mover/icechunk: Transactional, versioned Zarr storage format](https://github.com/earth-mover/icechunk/)**

If you’re excited about this project, please help us out by giving Icechunk a ⭐ on GitHub! 🙏
