Hello there,

I would like to know if it is possible to spot underwater reefs through world wind. My question is based on the fact that I am looking for a reef in the eastern Greek Aegean sea that was reported in 1978 by greek submarines (thats what the story tells...!!) and is present in any bythometric commercial chart.

I had a closer look with world wind but couldnt be able to get something. In the nearby area there are only two ships going by at the time the sattelite image was taken.

The area that I am refferring to is at: 38.00530N and 25.83410E

Any ideas whereas infrared imaging (or other maybe?) could actually find this mythical (for me) place?

Thank you for your bandwidth and time!

Kostis

I did work as an undergrad in the early 90's looking at submurged channels and terraces off the coast of Puerto Rico. Infra-red has very little penetration power in water. The best bands to look at underwater features are true color blue and true color green. Blue will penetrate at most 20 meters and green at most 10 meters in clear water. So unless the reef is quite shallow you will not see it. I checked the area in the landsat and did not see anything. below is an example of what underwater channels and reefs would look like. this is my undergrad research area.
