Arctic sea ice [allegedly] younger, thinner as melt season begins

Sea ice extent averaged over the month of March 2009 was 15.16 million square kilometers (5.85 million square miles). This was 730,000 square kilometers (282,000 square miles) above the record low of 2006, but 590,000 square kilometers (228,000 square miles) below the 1979 to 2000 average.

Has anyone out there seen any actual sea ice thickness measurements from the Catlin Arctic Survey? If not, why?
