seaice.de is Dr. Lars Kaleschke's compact gateway to polar sea-ice maps, GeoTIFF downloads, regional extent and area graphs, and the research institutions behind them. The homepage is sparse and specialist-facing, but it gives curious visitors a direct route from today's ice picture to the data and documentation underneath.
What is seaice.de?
This is less a conventional homepage than a scientist's well-used bookmark board. The first choices lead toward current Northern and Southern Hemisphere map products; another branch opens regional Arctic and Antarctic extent and area material. Below that sits a small network of serious destinations: AWI sea-ice physics, the AWI/ESA CS2SMOS service, University of Hamburg data, University of Bremen maps, and a specialist discussion forum. The presentation is plain, but the rabbit hole is deep and distinctly frozen.
What you can do there
- Open current Northern or Southern Hemisphere GeoTIFF products
- Inspect regional sea-ice extent and area graphs
- Follow links to institutional datasets and documentation
Why we picked it
seaice.de turns an enormous planetary process into a handful of direct doors. It is valuable precisely because it does not bury the working data beneath a glossy explainer: the maps, regional series, documentation, and institutional sources remain close together for visitors who want to follow the ice rather than merely read about it.
How to get the most from it
Start with the hemisphere that interests you, then move to the regional extent and area page when you want trends instead of a single map. Keep the linked documentation nearby, and treat GeoTIFF downloads as analysis files that may need mapping software rather than ordinary browser images.
Good to know
The site assumes some familiarity with sea-ice data, and several links lead to external institutions or specialist file formats. Its companion graphs page calls itself experimental, while University of Hamburg notes that finer-resolution ASI products can be more sensitive to atmospheric effects near the ice edge.
