Natural Science Forum / Earth Science / Oceanography / September 2003

Dear lurkers and participants,

Recently some sonar pictures of the sea
bottom off of northwest end of Cuba have
been posted on the Internet at:

http://www.earthfiles.com/Images/news/C/CubaSideScanSonars.jpg

The estimated length and width of these features,
which are sounded by loose sand, estimated as:

""up to 150 to 200 meters (492
to 656 feet) in  length and
maybe up to 50 to 100 meters
(164 to 328 feet) in width."

They occur at a depth of 700 meters.

The full story can be found at:

Does anyone on this mailing list seen features
like this before?   Does anyone have any
suggestion as what they might be?

NOTE: remove "NO from email address before replying.

Yours,
