MMAB Sea Ice Analysis Page
A satellite we use in constructing the sea ice analyses is overage and now
providing poor data. This has corrupted the analysis. We are working on
getting better data, but this may not be a speedy process. When we have
confidence in a newer process, it will be announced here. In the mean time,
though figures will continue to be produced, they cannot be relied upon
as formerly. 25 February 2009

Interpreting the Images
How the ice grids are constructed
Details on the regional images
The current sea ice state is important for both modeling efforts,
such as the sea ice model and the global weather model, and for sea ice
analysts, such as at the Anchorage
WSFO. Consequently we produce two sorts of field. One is suitable for
use by models, the global field. And the other is suitable for use by an
analyst. The analyst can apply intelligence and additional data sources
to produce a superior final product in his area of responsibility.

The Northern Hemisphere and Southern Hemisphere ice concentration
images are live maps. If you select a point on these images, you'll get
a magnified image of the region for about 550 km (300 nautical miles) around
that point. The orientation of the maps may be different from the full
hemisphere image. Please click
