Found you, Anuradha :) These are good facts. Re tweeted :)

Very interesting! You make this a good reference for science and geography teachers. Thanks.

Wow,I cant imagine it would be possible to excavate a shipwreck in the Mariana Trench. There are only three submersibles that could go that deep, but barely.

Good work on this post.

Great compilation of really deep bodies of ocean, but the Gulf is suffering this time. Excellent post Anuradha.

@Phoenix, Thnks for the re-tweet.

@Chan, Peter, Ron, Thnx for your support.
