The numbers are down slightly from the previous quarter (by 12.4 ZJ and 25.2 ZJ, respectively); on the other, the 1Q13 results were revised upward (by 8.4 ZJ and 10.9 ZJ respectively).
1 ZJ = 1 zettajoule = 1021 Joules = 15.9 million Hiros, where 1 Hiro = yield of Hiroshima bomb = 63 TJ = 63 terrajoules = 63 trillion Joules
These are cool units but a little ridiculous; for changes and trends it's easier to use terrawatts -- which is more prosaic since all of humanity's average energy consumption is about 15 TW (= 1 Civ) -- or Watts/square-meter, where you can divide by the total area of the ocean (361.8 Mkm2) or, since over 90% of the greenhouse-trapped heat goes into the ocean, by the total area of the Earth (510.1 Mkm2).
Then, the 12-month change in OHC is
0-700 m: 22.7 ZJ <--> 718 TW = 48 Civ = 2.0 W/m2
0-2000 m: 24.4 ZJ <--> 773 TW = 52 Civ = 2.1 W/m2
where I used the total ocean area. The 15-year trend for the 0-700 m region is 0.41 W/m2. There is only 8 years of quarterly data for the 0-2000 m region (roughly the top half of the ocean); it's trend over that time is 0.52 W/m2.
The 0-700 m region has warmed 37% more in the last 15 years than in the previous 15 years, which goes some way towards explaining The Pause.
Invariably someone will complain that these large heat changes represent a temperature change of only a small fraction of a degree Kelvin (via the definition of specific heat, ΔQ = mcΔT), to which the correct answer is, "yeah, so what, it's a big planet, we ought be measuring temperature in energy units anyway, as they are just related by a constant (Boltzmann's) that in a perfect world would have been set equal to one and done away with."
