Canadian Oceans

Even though the Mariana's Trench is not in and no where near Canada, we still have ocean environments of our own. In fact, Canada has the world's longest coastline. It borders the Pacific in the west, Atlantic in the east, and Arctic oceans in the north.

I think that the Arctic ocean, though not as deep as the Mariana's Trench, is still similar in a way. Since the Arctic air is so cold, the water tends to be cold as well, so the under the usual over-top ice covering, there are oxygen-rich waters, kind of like the Mariana's Trench (besides the ice covering). 

The oceans are an environment that haven't been explored too well. They are the least explored environments on this planet! Did you know that space has been explored more than our very own oceans? That's very shocking! For an environment that covers roughly 70% of the Earth's surface, we need to explore it more.  Time is short. There is global warming, oil spills, etc. that are happening. When need to fully explore this environment before there is no time left. There are estimates made that still 95% of the world's ocean and 99% percent of the ocean floor have yet to be explored.

The oceans hold many clues to earth's history and process. The oceans have led to the discovery of continental drift, chemosynthesis, and that the Black Sea was once a fresh-water lake.
