Amazing site for tracking Sea-Ice(extent and thickness) and Global Methane...
I'd post an excerpt, but the site is almost 100% images, so you'll have to visit it yourself:
https://sites.google.com/site/apocalypse4real/home
I believe it's a work-in-progress, so some images are MIA for the moment.
BTW: "apocalypse4real" is a regular on Neven's Sea Ice Blog and Neven featured the site in one of his blog posts:
These new sea ice concentration (top) and thickness (bottom) maps come from the GODIVA2 Data Visualisation demo page (see this explanation on how to get to the images).
As Apocalypse4Real wrote to me:
The UK data I have been tracking in Godiva2 is put out by the UK, The National Center of Ocean Forecasting (NCOF). The NCOF is a strategic partnership between the Met Office and the Proudman Oceanographic Laboratory, Plymouth Marine Laboratory, National Oceanography Centre, Southampton and the Environmental Systems Science Centre (ESSC) at Reading. The GODIVA2 data is output by the ESSC. See

The NCOF uses the Operational Sea Surface Temperature and Sea Ice Analysis (OSTIA) data for sea surface temperature and sea ice concentration and thickness analysis. OSTIA uses satellite data provided by the GHRSST project, together with in-situ observations to determine the sea surface temperature. The analysis is performed using a variant of optimal interpolation (OI) described by Martin et al., 2007. The analysis is produced daily at a resolution of 1/20° (approx. 5km). See

The GHRSST project, which is the source of the 5km data, is an international satellite observation project. It consolidates imagery and data from a number of hi-res platforms. See:

I don't know about the accuracy of these images, but they're visually stunning. This is yet again another great tool for assessing and interpreting the situation up North. Thanks go out to Apocalypse4real for starting a website to make viewing of these images easier.
