Arctic Sea Ice Volume in 2013 Up 50%. (h/t NorthWest Passage 2013 blog)

“Measurements from ESA’s CryoSat satellite show that the volume of Arctic sea ice has significantly increased this autumn.

The volume of ice measured this autumn is about 50% higher compared to last year.

In October 2013, CryoSat measured about 9000 cubic km of sea ice – a notable increase compared to 6000 cubic km in October 2012.”

“90% of the increase is due to growth of multiyear ice”

“This year’s multiyear ice is now on average about 20%, or around 30 cm, thicker than last year.”

“the volume of ice year-to-year was not varying anything like as much as the ice extent”
