Vast information resources exist for those who are curious about how the Arctic, and its ice in particular, is changing. Satellites and other sensors record data constantly, and various institutions publish this data (raw, or analyzed in various ways, or both) on the internet for unrestricted use. Many of these sites (see Links below) do an excellent job of presenting some of their products to the public. Still, the daily data flow is so large and complex that some of the potential is still untapped.

So the first goal of this site is to pull together products from all these sources and present them in a curated, easily navigated and up-to-date form.

The second goal is to build new products (animations, images, charts, etc.) from the daily data flows by automated use of various image-processing tools, and add these to the site, with annotations and explanations of their significance.

The third goal is to make all the same tools and resources available interactively, either by filling in forms or by scripting. Some of these tools will be useful to relative newcomers, and others will be geared toward advanced users, who will also have access to storage on the server.


This site consists of two main components, both hosted on a virtual machine in the Amazon Cloud. First is a Python program called floe, running on a daily schedule to refresh a set of static content pages (see https://github.com/dsteinkraus/floe for the full source code and documentation). The floe framework is extensible and uses various image-processing programs and libraries (like ImageMagick and NetCDF4).

The other component is a Django front end to provide user interactivity for the online data processing tools, as well as services like account management.

This is just a starter list, will be refined and annotated over time:

This effort was inspired by the many excellent contributors to the Arctic Sea Ice Forums, especially user "A-Team" on that site.
