I have a lot of information on Puget Sound wrecks, how best to share it?

[Belzelbub]

For me..... the best info would simply be the EXACT GPS coordinates along with any narrative or description or insight that might be specific or particular to the particular site.

Agreed. As an example, the link below should take you to the database maintained by FWC for the artificial reefs in the state of Florida. This includes some wrecks as well that were purposely sunk for the artificial reef program.

Some of the info they maintain may not be applicable here, but it at least gives an idea of what would be good to include.

From my perspective, what would be most useful for me would be:
Name
GPS Coordinates
Description
Depth
Relief

They provide this in a variety of formats. (PDF, Excel, etc.)
