After the levelling off in volume gain we saw during February (see previous PIOMAS update), the 2015 trend line has continued on a more 'normal' course. The gap with record year 2011 has widened from 1675 to 1907 km3, but other than that 2015 has managed to creep a little bit closer to the other top years. Difference with 2012 went from 1329 km3 on March 8th to 1147 km3 at the end of March, for instance. And 2015 is now lower than big spring melt year 2010, albeit just 17 km3.
The PIOMAS volume graph produced by Wipneus shows the details more clearly:
The trend line on the PIOMAS sea ice volume anomaly graph is still hovering in the positive two standard deviation zone:
