It turns out, humans aren't the only creatures in need of a winter vacation. In 2002, scientists discovered an area in a remote part of the Pacific Ocean, partway between Baja California and Hawaii, where typically coastal great white sharks will migrate to in the winter. The scientists named the spot the White Shark Café and some sharks hang around the area for months before heading back to the coast for warmer weather.

Just two vestiges of ice remain from our planet's last ice age: the Greenland Ice Sheet and the Antarctic Ice Sheet. The latter of the two is staggering in size. Clocking in at 5.4 million square miles, according to the National Snow & Ice Data Center (NSIDC), it's roughly the size of the continental United States and Mexico combined!

There's around 20 million tons of gold dispersed throughout the oceans. It is, however, diluted pretty much to a pulp—its concentration is only a few parts per trillion, according to the National Ocean Service. The ocean floor also has undissolved gold embedded in it, but it's not cost-effective to mine it. However, if the ocean's gold were equally distributed among every person on earth, we'd each receive nine pounds of it.

HSAS GM Ocean Facts That Will Blow You Out of the Water

With so much going on well below the surface, it's easy to forget that the oceans are teeming with life. In fact, 94% of life is aquatic, according to the USA Science & Engineering Festival. That means those of us who live on land are part of a very, very small minority.

The biggest ocean waves are not the ones that you can see from the shoreline. As physical oceanographer Kim Martini told Deep Sea News, the largest waves that occur in the ocean are called internal waves, which take place between two fluids with two different densities. As these internal waves travel—for thousands of miles, no less—they can grow to be 650 feet tall.
