    A quick 1 minute summary snapshot on How many active volcanoes are there in the world? . The mention of active volcanoes on the ocean floor is interesting and makes you wonder how much influence they have on ocean heating. Around Antarctica there are about 200 volcanoes. 93 of them have only recently been discovered because of the previous inability to seem them.  Currently there are about 30 active volcanoes on the Pacific Ring of Fire, so how many active ones are there under the ocean?   Food for thought.
