OHC for both regions is actually down slightly from a quarter ago, but this seems like the usual occurrence. But they're both up compared to 2Q16:
0-700 m region four-quarter change: +1.8 W/m2
0-2000 m region four-quarter change: +2.3 W/m2
where, again, I spread the heat change over the Earth's entire surface, since almost all (about 93%, plus or minus) of the trapped heat goes into the ocean.
By my calculations, the OHC of the 0-2000 m region -- basically the top half of the ocean -- is accelerating since 1Q2005 at 0.04 ± 0.02 (W/m2)/yr. That uncertainty is 2σ, and doesn't include consideration of autocorrelation.
Here are the graphs. Since OHC is the best measure of a planetary energy imbalance, it's clear the planet has kept warming.

I find this interesting. I expected very little energy would be lost in the El Niño, and it appears very little was.
