Scientists should not be telling folks that they're inventing the wheel.
We're talking 150 years ago!!

Gary Pearse says:
Undersea volcanoes have been known by geologists for well over a century. Iceland, Hawaii and a host of other islands and terrains are born of undersea vulcanism. I mapped “pillowed” basalts in the Archean of the Canadian Shield over 50 years ago myself and these are 2.5-3.0 billion years old.

Click on the images on the right for modern Hawaiian pillows and for ancient precambrian pillows in the Canadian Shield. It is a common thing among scientists these days to be “rediscovering” well known phenomena and finding them much more prevalent “than thought (by themselves)”. Thought seems to be of declining interest. If they go for the Nobel Prize, I might try to horn in on it for my prior work but of course there will be another 20,000 geologist in line.
Oh, and Alan the Brit:
“I don’t suppose they just happen to lie around the West Antarctic Penninsula or could possibly affect the ocean temperatures locally at all,”
Yes they are:

They were also reported by WUWT some time ago. Indeed the most common rocks on the Western Peninsula are volcanic rocks.
