Any good free sources for bathymetry maps online ?
 

I'm building a Dangerous Waters campaign and I really need a good resource for various bathymetry maps online to research different areas where I'm staging my conflict. I'm especially trying to find a good map of the topography of the entire Reykjanes Ridge but so far, all I've found were articles about it and no detailed maps of the entire underwater parts of it which won't do because I need specific locations. Every site I've looked for these maps want to charge me money for them. Are there any good free resources out there with this information ?

Why do you need real maps if you are planing to do DW campaign ? DW has much simplified topography.

Anyway here is source I know:

http://www.gfdl.noaa.gov/products/vi...opography.html

But it's raw bathymetry data, no maps usable without some software. The format is quite simple anyway. What is lat/long of the site you are looking for ?

It's a little bit of chrome as well as landmarks for my various missions. If the mission is over or along an certain feature , it would be good to have it marked on the map. This will first off, look nice, and seccondly give landmarks to otherwise featureless battlefields that are in the middle of water areas where no shore is visible.
I just found a pretty helpful map at

http://www.gebco.net/data_and_products/gebco_world_map/

It's nice because it actually has names for a lot of the underwater features which is what I want. If you know of anything that goes into deepter detail that lists the names of features, let me know.

I see .. nice found.

I've found these helpful.
