G'Day Paul,
I just had to have a look in Google Earth... it doesn't show an island there but the depth of the ocean gets to 0ft!!!
I haven't come across anything that does what you want (that doesn't mean it doesn't exist though!). I have spent some time surfing some excellent mapping sites, so I checked my favourites and I'm a bit puzzled cause I don't have them in my favourites... maybe I have them at work?
If you could find a map with the name on it would that do?
I think the University of Texas has some excellent mapping resources online. The other site I've had in mind that is pretty impressive is something to do with the JPL/NASA - they have MrSID format maps (actually satellite images) down to very good resolution (I found my house!) - but I don't think there are any names on the map/images

.
It's a curly one... I've tried a few searches without any luck, and no doubt so have you!
Planning an eclipse trip are we???
Al.
