Given ongoing Extreme Weather Patterns I highly doubt, that this PIOMAS Figure is correct.
Just go outside for a Day & feel at what force Winds are blowing meridionally, N->S and viceversa.

Gridded PIOMAS thickness data was released, not yet the official volume data and graphs last time I looked.

Here is the animation for March 2018.

With a volume of 21.9 [1000 km3], 2018 is still second lowest. Much closer to third than the first place though.

Attached volume and volume anomaly graphs.

March 2017 had (very approximately) three times the Fram export of ice that of March 2018.  (January and February had vaguely similar export amounts this and last year.)
Arctic ice is healthy for children and other living things.

Yes. Not much MYI this year.

Zack, if it isn't too much trouble, could you update this temperature graph (the one at the bottom of the page, with the rankings)? I'd like to use it for the PIOMAS update:

No problem! It should be updated now at http://sites.uci.edu/zlabe/arctic-temperatures/. Thanks!

With a volume of 21.9 [1000 km3], 2018 is still second lowest.
Average Arctic sea ice VOLUME for April 1, for the period 1980-89, was ~30,200 cubic kilometers. April 1, 2018 Arctic sea ice VOLUME is ~21,900 cubic kilometers, ~ 8300 cubic kilometers LESS than the 1980-89 average for April 1.
Like 2015, 2016 & 2017, 2018 Arctic sea waters(which used to be ice & reflected solar energy to space)  have set themselves up to absorb much excess AGW predicted solar energy, while the sun is at its approaching maximum elevations in the sky. Any downwellings in those .5+ million square kilometers excess AGW generated waters, will transport excess AGW solar absorbed energy directly downward to Arctic continental shelves or into deeper Arctic waters, for storage.... energies that had not been available previously to the Earth. It has also been determined that excess solar energy can be absorbed through thin AGW generated ice when the sun is at its highest elevations in the Arctic....even more energy stored in Arctic waters.
////////
For half a century(+?), the solar TSI has been languid. For 11+ years the solar TSI has been well below average(including a 3+ year low period setting a 100 year record). For many years, due to the low solar TSI, AGW deniers have declared an ice age.
But Earth has NOT even returned to early 20th century low temperatures. For 395+ STRAIGHT months Earth temperatures have been over the 20th century average. AGW deniers should be happy there are no gay activities. ;D The first decade of the 21st century has been the hottest recorded decade, also including the 20th & 19th century recorded temperatures. The last five years have been the hottest 5 year recorded period, including the 21st, 20th, & 19th centuries. 2014, 2015, 2016, & 2017 has been the hottest recorded successive years, including the 21st, 20th, & 19th centuries. All this while solar TSI is low, which science says is only a blip low. For billions of years, the sun has continued to warm & WILL continue to warm. Once solar TSI becomes its normal, higher(& higher, still) self, Earth temperatures (already escalating), will take a faster elevator, upward!
//////
On January 1, average Arctic sea ice extent for the 1980's was 14.52 million KM2. Like 2015, 2016, 2017 & now 2018,  MAXIMUM Arctic sea ice extent did not reach 14 million square kilometers. Indeed, 3 months of Arctic sea ice freezing has disappeared!!

 A comparison of SMOS and PIOMAS sea ice thickness anomalies (baseline mean since 2011).

Thank you seaice.de.
That does not look good. All the positive anomalies are in areas that are likely to melt out.

Those anomalies look like less ice went through Fram than usual, but more through Nares.

Does SMOS have a more recent baseline than PIOMAS? They seem to be showing almost the same information, just shifted.

could be that SMOS takes longer to gather the data.

I think the CAA anomaly is due to persistant CAA export (aka garlic press) as well as temp, mobility etc.

thanks to A-team for tips on ascat graphics

edit: some of that MYI may still be working it's way through to Baffin Bay.
edit: after looking again, some more MYI is making it's way around the Beaufort

Rapid Ice Loss and United Nations General Assembly Motion 101292 (ref. UNFCCC-TAL-SRS/02/04/2018) - Rapid Loss of Sea/Land Ice Presented to UN General Assembly after Rio Earth Summit

United Nations Secretary-General Javier Pérez de Cuéllar issued authorization for the Hopi Nation to present their ethnoclimatology motion to the UN General Assembly which stated that any sustained warming on the Polar Regions would result in very rapid loss of ice, the investigation request remained languishing then in UN files for the following 26 years. After the Copenhagen Summit COP15 failed to continue pursuing the Kyoto Protocol route COP3 and the Bali Road Map COP13 (leading to nearly 10-year hiatus until the Paris Agreement), the UNESCO delegation of Bolivia in Paris and His Excellency Evo Morales asked me to present about the UN whereabouts of the matter at the Cochabamba Climate Summit (CMPCC), this UNFCCC-TAL-SRS02/04/2018 is a further to ask UN to respond on the First Nations of Americas 1992 statement that any sustained warming (succession of consequtive warm summers in the Arctic) would very rapidly damage ice. This re-presents some of the CMPCC arguments, the new UN motion also clarifies on matters as the First Nations of Americas traditional position on geoengineering and modifications of weather:

PIOMAS gridded thickness data was updated to 15th April.
 
The annual max seems not to have been reached, see attached volume and volume anomaly graphs.
