This page has a lot of awesome facts about the sea including that the average piece of seawater freezes at -19 degrees Celsius. And that Australia “owns” the most amount of ocean. And that Mount Everest is more than a mile shorter than the deepest point in the ocean (called the Challenger Deep). And that the heart of a blue whale is the size of a Volkswagon. (!)
The fact that the Grand Banks are closed to fishing, however, is not quite true. True, the cod and flounder fisheries were halted with the 1992 moratorium, but there are other species, including shellfish, that are still being fished (and in some cases, thriving) up there.
So if you’re interested on reading up on the salinity, fishing rights, volcanic activity and assorted other facts, that’s the place to go.
