NOAA, The National Oceanic and Atmospheric Administration, reports [*] on the discovery, published in Nature Climate Change (full article is pay-walled):
[...] that between the 1990s and 2010, acidified waters expanded northward approximately 300 nautical miles from the Chukchi Sea slope off the coast of northwestern Alaska to just below the North Pole. Also, the depth of acidified waters increased from approximately 325 feet below the surface to more than 800 feet.
The United Nations Development Programme explains that
[...] since gases such as CO2 dissolve more readily in colder water, ocean acidification will progress – already is progressing – much more rapidly in the Arctic and Antarctic, where a number of species are already facing challenges in fixing their shells. Under a lower pH ocean future, increasing numbers of calcium carbonate fixing organisms could face dramatic losses or even extinction.

Why does the data stop in 2010? This makes it seem like they are only reporting on 2/3 the data.

Probably more recent data is still paywalled....
No, you are mistaken. I've always had this sig.

Looks like they are melding together multiple datasets in some byzantine way (but it is impossible that any errors from this can affect their conclusions):
That still doesn't explain why there was no more recent data available.

Probably not collected.
Remember, those were the years when King Harper ruled Canada.
Anything that had to do with the environment or global warming was cut and shredded.
And now, it's the US' turn.

From the Eurekalert article:
The researchers studied water samples taken during cruises by Chinese ice breaker XueLong (meaning "snow dragon") in summer 2008 and 2010 from the upper ocean of the Arctic's marginal seas to the basins as far north as 88 degrees latitude, just below the North Pole, as well as data from three other cruises.
