Sea Ice Thickness Forecast by TOPAZ 4

The Operational TOPAZ4 Arctic Ocean system uses the HYCOM model and runs every week to provide 10 days of forecast (one single member) and 7 days of analysis (ensemble average) for the 3D physical ocean, including sea ice. More Arctic related scientific products are available at the MyOcean website. Registration is free.

The MyOcean project is funded under a European Commission 7th Framework Programme and is planned to continue at least until end of September 2014

Now is the time with most top and bottom melting. Recognize the upcoming Swiss Cheese effect after the break. The colors range from 0 to 3 meters, black is above.

Sea Ice Thickness Forecast

Just out of curiosity I wanted to know what the average sea ice thickness in the Arctic actually is. So I took the available GSFC Dataset, filled the holes and used the overlapping time range with the IJIS/JAXA data set to perform a least error approach and gained a table starting 1979-01-01 and ending 2010-12-31. This range is also covered by the PIOMAS sea ice volume data set and calculating daily thickness was easy then.

But average thickness is a value which works only within a certain range. Having an average of zero, does no way mean there are any floes with negative thickness. Also, it turns out yearly thickness minimum is not in September, but rather in December when the Arctic is covered with a lot of fresh and thin ice.
