Oceans by Roger Pink

The Great Unknown...Right Next To Us

Although oceans and other bodies of water cover 70% of the Earth's surface, we are only just now beginning to explore their depths in detail. I came across some neat topographical, sea floor age, depth, etc. maps of the oceans. Thought I'd share what I found. I've posted some below, but due to resolution constraints I have posted better images on my website, found here.

Ocean Facts!

The deepest part of the world's oceans is the Mariana Trench. The trench is about 1,580 miles long and about 43 miles wide. The maximum known depth of the trench is 6.8 miles at Challenger Deep. At the bottom of the trench, the pressure exceeds 1000 atmospheres. Remarkably, life has adapted and thrives in these extreme conditions at the bottom of the trench.

The deepest part of the Atlantic Ocean is Milwaukee Deep, part of the Puerto Rico Trench. It has a maximum depth of 5.2 miles.

The deepest part of the Indian Ocean is Diamantina Deep, part of the Diamantina Trench. It has a maximum depth of 5.0 miles.

The average depth of the Atlantic Ocean is 2.4 miles. The Pacific Ocean average depth is 2.7 miles. The Indian Ocean average depth is 2.4 miles. The average depth of the Arctic Ocean is 0.6 miles. The Arafura Sea north of Australia has an average depth of 250 ft (0.05 miles).

Conclusions

I hope you enjoyed the maps and got a chance to see the additional images and higher res images found on my website. I am very impressed with the work the NOAA has done and has made available online. Till next time -Roger
