Arctic sea ice in 2015 is nearly ten inches thicker in Canada than it was in 2013 per ESA Cryosat

Arctic sea ice in the area is now nearly 10 inches thicker. 

4/20/15, "ESA CryoSat Sees More Arctic Sea Ice In Canada,",

"A satellite from the European Space Agency has recorded that the amount of Arctic sea ice has gone up in Canada, even though the country had the lowest winter range area [extent] of coverage in ice that has ever been recorded [in five years] since the satellite began coverage in 2010.

The information comes from the CryoSat satellite adventure. Over the past five years its mission is to study the Arctic sea ice floes. These recent measurements from CryoSat show a two dimensional view of the Arctic, and by measuring the range and depth of the ice, scientists can see how the cold winds there can cause the ice to either thicken up or spread out and flow more, making them thinner.
Arctic Sea Ice Measured by Thickness and Volume
ESA CryoSat can also measure how the Arctic sea ice behaves on its adventure in the water by measuring the height of the Arctic sea ice that sits over the sea water. Then, it combines both sets of data and uses a special formula to determine the volume of the ice. The latest measurements taken in February 2015 show an average thickness in the Arctic sea ice of almost two meters, which means there is about 24,000 cubic kilometers of it in total.

Ice Amounts Thicker, In More Areas than Previous Years

This revealed that the Arctic sea ice in the area is now thicker by nearly 10 inches, which means it has gone up 17 percent from the amount discovered two years ago. For instance, in the data there was a picture that revealed that there was an area in the Beaufort Sea that is now covered with ice, whereas 8 years ago this area had no ice and showed bare groups in the photos."...


February 2015 Arctic sea ice thickness up 17% from 2013 per Cryosat. Sea ice volume is best indicator, thickness and volume both up in recent years-BBC. BBC report refers to Arctic ice in general as opposed to "Arctic ice in Canada" referenced in above article.

4/17/15, "'3D Cryosat' tracks Arctic winter sea ice," BBC,

Although Arctic sea ice set a record this year for its lowest ever winter extent--that was not the case for its volume, new data reveals.

Europe's Cryosat spacecraft routinely monitors the thickness of floes in the far north. The thinnest winter ice it has ever seen was in 2013. This February, in contrast, the Arctic floes were about 25cm (17%) thicker on average. The long-term trend is, however, still downwards, the Cryosat team cautions.
"Year to year, the numbers will jump about, and it just so happens that we've seen relatively high levels of Arctic sea ice thickness and volume in recent years," said Rachel Tilling from the UK's Nerc Centre for Polar Observation and Modelling (CPOM). 
"But sea ice volume is definitely the number people should watch, because it is the most reliable measure of how much ice is left. It's also what we need to understand the processes that have caused the Arctic climate to change which, in turn, will help us to build more accurate models of what may happen to sea ice in the future," the University College London researcher told BBC News.

The Cryosat team released its Arctic winter assessment here at the European Geosciences Union General Assembly in Vienna, Austria."...


From August 2014, University of Illinois Cryosphere satellite also showed Arctic ice volume increase:

8/30/2014, "Myth of Arctic meltdown: Stunning satellite images show summer ice cap is thicker and covers 1.7million square kilometres MORE than 2 years ago...despite Al Gore's prediction it would be ICE-FREE by now," UK Daily Mail, David Rose
"The satellite images published here are taken from a further authoritative source, the University of Illinois’s Cryosphere project.

They show that as well as becoming more extensive, the ice has grown more concentrated, with the purple areas – denoting regions where the ice pack is most dense – increasing markedly.

Crucially, the ice is also thicker, and therefore more resilient to future melting. Professor Andrew Shepherd, of Leeds University and University Coillege, London, an expert in climate satellite monitoring, said yesterday: ‘It is clear from the measurements we have collected that the Arctic sea ice has experienced a significant recovery in thickness over the past year.

‘It seems that an unusually cool summer in 2013 allowed more ice to survive through to last winter. This means that the Arctic sea ice pack is thicker and stronger than usual, and this should be taken into account when making predictions of its future extent.’"...
