Manannan's association with the ocean needs little explanation, so here instead are some interesting facts:

The oceans provide 99 percent of the Earth's living space- the largest space in our universe known to be inhabited by living organisms. More than 90% of this habitat exists in the deep sea known as the abyss, and less than 10% of this living space has been explored by humans.

The oceans cover 71 percent of the Earth's surface and contain 97 percent of the Earth's water. Less than 1 percent is fresh water, and 2-3 percent is contained in glaciers and ice caps.

The highest tides in the world are at the Bay of Fundy, which separates New Brunswick from Nova Scotia. At some times of the year the difference between high and low tide is 53 feet 6 inches, the equivalent of a three-story building.

At the deepest point in the ocean the pressure is more than 8 tons per square inch, or the equivalent of one person trying to support 50 jumbo jets.

At 39 degrees Fahrenheit, the temperature of almost all of the deep ocean is only a few degrees above freezing, although the top ten feet of the ocean hold as much heat as our entire atmosphere.

If mined, all the gold suspended in the world's seawater would give each person on Earth 9 pounds.

If the ocean's total salt content were dried, it would cover the continents to a depth of 5 feet.

Ninety percent of all volcanic activity occurs in the oceans.
