A-Z Blogging Challenge: O Stands For: Oceans

(An example of the five major oceans and the World Ocean. SOURCE)

71% of Earth is covered by ocean. The area of the World Ocean--which is the Atlantic, Arctic, Indian, Pacific, and Southern Oceans combined as a single body of salt water--is 361 million square kilometers (139 million square miles), and is approximately 1.3 billion cubic kilometers (310 million cubic miles) in volume. The average depth is 3,790 meters (12,430 feet), and the deepest point is 10,924 meters (6.787 miles), at the Mariana Trench.

99% of Earth's living space is provided by the oceans--it is estimated they provide 300 times the habitable volume of land habitats. 90% of of that living space exists in the deep sea, the area below 200 meters (660 feet). Around 230,00 marine species are currently known, but that number could be up to ten times higher.

Humans have explored less than 10% of the ocean. The Challenger II reached the Mariana Trench in 1951 and named its deepest point Challenger Deep, and the Trieste also reached the Trench in 1960 with a two-man crew, but much of the ocean floor is still unmapped and unknown.

News and information on ongoing and past projects, such as the Indonesia-USA Deep-Sea Exploration and the exploration of the deep reefs of the Indo-Pacific, can be found HERE.




Have you ever seen the ocean?

I LOVE the ocean... Currently I am a block and half away from the Atlantic Ocean in Central Florida. Beautiful.

I've been to the Pacific as well. Other bodies of water I've visited is the Gulf of Mexico, Caribbean Sea, Mediterranean Sea, Aegean Sea, Baltic Sea, and North Sea.

You can tell I love any place by the sea. I also live a five minute walk to Lake Michigan in Chicago.

I feel like I'm on a great adventure when I stop by your site.

It's like having a private tutor...I'm trying my best to absorb it all, but sometimes I think there is a black hole in my head where it all gets sucked into - then the oceans roll in and wash way what's left.

Fortunately, I can always come back here and reload with new and exciting information.

Have a wonderful day,

Michael, I'm just across the "road" from you - Portugal. Waaaave!
G.E. I was so fascinated I clicked your Marianna link but it kept crashing the computer. I'm using Chrome - thought I'd just let you know (also the final image isn't showing). I love the sea, I really do but it's so unpredictable.

Melody Jackson said...

I love the ocean as well! I love the pictures of the sea slug and pymgy seahorse! The ocean is so mysterious, just when we think we know all about it, something new surfaces that blows our minds.

I love all the pretty pictures you use in your post, I would like to give you the Versatile Blogger Award.

You can accept your honor here:


Old Kitty said...

Oceans are awesome!! Oceans ROCK!! Oceans should be treasured and cared for and loved and not dumped on!!! :-)

There is so much to explore and so much to still uncover! Amazing! Take care

the writing pad said...

I never cease to be amazed by the fascinating facts and figures I find here :-) I have seen the ocean but only from the top ...
Thanks for the O Post!
All best

M Pax said...

The ocean is beautiful. Been to the Caribbean, Atlantic and Pacific. They're all different.

Jessica Bell said...

It really is amazing what is out there that we don't have access to, huh? Beautiful shots you've chosen to post too. The seahorses are mmy fave :o)

Alex J. Cavanaugh said...

Seen the ocean many times and even swam in it, but never below the surface. Can you imagine the critters living in the depths?

Siv Maria said...

Ocean right outside, the sound of waves put me to sleep at night.

Emily Rose said...

The ocean is so incredible. I love the last fish.:D

Susan Kane said...

The ocean is only 20 miles away, and yet we go only a few times a year. Life cannot be allowed to be so busy, that we can't ignore all that beauty so close to us. New resolution: Sped more time at the ocean.
Wonderful photos, and excellent info.

Donna Weaver said...

I lurves the ocean. I've sailed the Pacific 3 times (and once just to Hawaii and back). I'd love to do my retirment on cruiseships. =D

Josh Hoyt said...

I actually have a psychedelic Goby. He is pretty cool and is surviving. It is amazing what the oceans do for us and the amount of life that are in them.

L.G.Smith said...

Uh-oh. I feel my inner geography geek coming out.

Did you know the Marianas trench is a subduction zone? Than means two plates are being pushed together there and one part gets forced down below the other, moving like a conveyor belt. It gets pushed so deep it melts and becomes magma which then resurfaces through volcanos to make new land. Recycling at it's finest.

Holly Ruggiero said...

I love oceans. You posted my favorite fish today, the Mandarin fish. I really like the little pygmy seahorse too.

Lynda R Young said...

I live 15min drive from the beach so oceans are a familiar sight. For such a huge body of water, they have so many different looks. I love your pics.

Shelley said...

Wow, awesome pictures! It's interesting how people travel into space, when we haven't even dicovered everything on this planet! Great post! :)

Elizabeth Mueller said...

Yes, I have! The Pacific, that is.
So beautiful. I love that sea horse, great blend ins! :)


N. R. Williams said...

Oh...that last fish is beautiful. I saw a sea horse at Ocean Journey in Denver but the photo didn't turn out very good. Thanks for sharing this information.

Karen B said...

I've lived about 15 minutes from the ocean for my entire life. I love the sound of it, the peace I feel sitting on the beach watching it. Love the way it crashes onto the shore. Learned a few things I didn't know. :-)

The Words Crafter said...

I absolutely LOVE learning about all the new species of creatures constantly being discovered, so strange and beautiful and mysterious.

Fantastic photos, too!

Trisha said...

I love oceans! There's something truly fascinating about the deep ocean, too.

erica and christy said...

i think i just got a book idea. thanks for the inspiration! beautiful post. christy

Carla said...

Oceans really are amazing...I've been lucky enough to visit quite a few. Right now, I live in part of Houston that is about 90 minutes away from the beach.

I LOVE your pictures...they are fantastic!


Duncan D. Horne said...

There are some fascinating creatures down there that I can only dream of seeing!

Cindy said...

Reading your A-Z postings is like flipping through an encyclopedia.. and I mean that in a good way :)

The Golden Eagle said...

Laughingwolf: Thanks!

*sigh* The oceans seem to be getting destroyed no matter where you look. And there's so little being done to stop it.

Michael: I wish I was where you were1 :) It sounds wonderful.

Wow. You've been all over!

I've never seen one of the Great Lakes.

Jenny: I hope I'm not a terrible guide on these post adventures. :)

Well, I'm not planning a test or anything--so no problems with just sitting back and enjoying the ride!

Lauracea: LOL.

I think I fixed it--I hope you find the new link helpful!

It is, true.

Melody: I'm glad you enjoyed the pics! :)

It's amazing how that happens--and intriguing! Who knows what might come up.

Thank you so much for awarding me!

Old Kitty: You said it! We pollute and destroy the oceans, and it continues to get worse--something should be done about it, but of course business and other sources of resistance get in the way . . .

Karla: Thanks! I'm glad you've been enjoying my posts so far. :)

You're welcome!

M: I've only seen the Atlantic--and that from a pretty good distance because the tide was out.

Jessica: Yup!

Mine too. :)

Alex: There's so much potential discovery!

The Golden Eagle said...

Siv: How cool! :)

Emily: Me, too--it's so colorful, isn't it?

Susan: I hope you get some time to see the ocean this year!

Thanks! I'm glad you enjoyed it. :)

Donna: To Hawai'i and back? That sounds like an amazing experience! I'd love to go on a boat sometime--but I think I had better learn how to swim first. LOL.

Josh: Awesome! They're such cool fish. :)

It is.

L.G.: Yes, I did know that! It's pretty amazing, isn't it?

Holly: I hope you enjoyed the pic of the Mandarin fish!

I love pygmy seahorses. :D

Lynda: We don't live near the ocean, so I've only seen it a few times--but it does have so many different faces, doesn't it?

Thanks! Glad you liked them.

Shelley: Thank you!

They call space the last frontier, but there's so much in the ocean that hasn't been discovered!

Elizabeth: Cool. :)

It does have pretty amazing camouflage, doesn't it?

Nancy: Seahorses are such interesting creatures--and cute besides. :D

You're welcome!

The Golden Eagle said...

Karen: I've never lived that close to the ocean for any amount of time--so I've never experienced anything like that. It sounds wonderful!

The Words Crafter: Me, too. Every new species they find somewhere in the ocean is just amazing . . .


Trisha: Definitely. :)

Christy: Awesome! I love getting new book ideas--unless I'm in the middle of a project! LOL.

You're so welcome!


Carla: I hope you get to visit the ocean often where you are. :)

I'm glad you enjoyed them!

Duncan: Me, too. Just too out of this world!

Cindy: LOL. Thank you! I'm glad you find something worthwhile in what I post.

Hey there Golden. I've seen the ocean alright! I have a house on the Pacific Ocean and it's different every day.

What an amazing post. The info was staggering and the pics just gorgeous. Has a sci-fi feel to it.

I love the opening image showing different ways to view the ocean. Plan to show it to my students, in fact it is a perfect thing to put on the wiki.

I have seen much of the Atlantic shore line from Maine to Florida and was also blessed to see the Pacific Coast line of Oregon.

The Golden Eagle said...

Denise: Must be nice, living so close to the ocean! :)


Well, SF is the main genre I write.

Stratoz: I hope it comes in handy! :)

That's a lot of coastline! Wow.
