Is the total volume of Arctic sea ice also declining?

The typical estimate of the sea - level change is five metres, a value arrived at by taking the total volume of the West Antarctic Ice Sheet, converting it to water and spreading it evenly across the oceans.

PIOMAS has been used in a wide range of applications but arguably the most popular product has been the time series of total Arctic sea ice volume which we have been putting out since March 2010 (see also Fig 1).

But which variable — proportion of total ice, or volume loss — is really the independent one?

The sampling issues arise from the fact that sea ice is highly dynamic with lots of spatial and seasonal variability so that measurements from individual moorings, submarine sonar tracks, and aircraft flights can only construct an incomplete picture of the evolution of the total Arctic sea ice volume.

Greenland's ice sheet has a total volume of 2,850,000 km ³ (so sayeth Wikipedia).

I sent some questions to some of the authors of the new study showing how much the thickness and total volume of Arctic sea ice have declined since 2003.

Wili: As ice volume decreases, the fraction of volume which is new ice increases, and hence the year to year variability in new ice becomes a larger fraction of the total ice volume variability, so I don't think the smoothed downward slope will stay as smooth, i.e. you should expect bigger surprises to the upside on a given winter if it is cold and has heavy snow fall.

In 2003, 62 percent of the Arctic's total ice volume was stored in multi-year ice, with 38 percent stored in first - year seasonal ice.

By 2008, 68 percent of the total ice volume was first - year ice, with 32 percent multi-year ice.

Even if the subs up there took constant ice thickness measurements, it would still be an incomplete picture, a series of snap shot pictues of local conditions, which wouldn't sum to big picture measurement of total ice volume.

Research has shown that glaciers around the world have been retreating at unprecedented rates, and Alaska, which has only 5 percent of the total ice Greenland has, lost a volume of ice equal to nine states 3 feet thick between 2004 and 2007 alone.

This work concerns only sea ice extent without considerations of the age, thickness, and total volume of sea ice.

As you mentioned gravity changes due to many causes, also orbital drift and large guesses with potential biases make the estimates of total ice volume have very large error bars.

(d, e) Total area of Arctic sea ice and AMOC volume transport as a function of time in the CTL, LW, and SW experiments.

Al Rodger: Well, yes, according to the PIOMAS the total change in Arctic ice volume during prior normal period was from about 28000 cubic km in winter to about 12000 at the minimum, or a change of about 16000 as you stated.

Given the close correlation between latent heat of fusion and net energy in the Arctic, this excellent animation of sea ice volume gives one of the indications of the total energy in the Arctic.

All of these characteristics (except for the ocean temperature) have been used in SAR and TAR IPCC (Houghton et al. 1996; 2001) reports for model - data inter-comparison: we considered as tolerable the following intervals for the annual means of the following climate characteristics which encompass corresponding empirical estimates: global SAT 13.1 — 14.1 °C (Jones et al. 1999); area of sea ice in the Northern Hemisphere 6 — 14 mil km2 and in the Southern Hemisphere 6 — 18 mil km2 (Cavalieri et al. 2003); total precipitation rate 2.45 — 3.05 mm / day (Legates 1995); maximum Atlantic northward heat transport 0.5 — 1.5 PW (Ganachaud and Wunsch 2003); maximum of North Atlantic meridional overturning stream function 15 — 25 Sv (Talley et al. 2003), volume averaged ocean temperature 3 — 5 °C (Levitus 1982).
