    I’m doing a research project about renewable energy, and I need a

    map of ocean depths near shore lines in order to figure out where one can

    place wind turbines. I also need information about which country a given point

    in the ocean belongs to (near shorelines).

    On natural earth data I can find information about countries (10m_admin_0_countries)

    and bathymetry in 0-10-100 meter scales. But the country borders does not extend into the sea,

    and the bathymetry data is not fine enough. I specifically need a 60 meter depth border/polygon.

    10-20-30-40-50-60-70-80-90-100m data would be very useful for me.

    How do I get this kind of data? Is there some universal rule to determine

    which piece of ocean belongs to what country, or can I download a polygon file?

    Any hints would be greatly appreciated!

    Thanks, this is exactly the kind of map I was looking for!

    I could not really find any information on bathymetry. Googling bathymetry

    takes me to the British oceanographic data centre, where they also have low depth resolution

    near shores. Even NOAA (http://ngdc.noaa.gov/mgg/bathymetry/relief.html) does not seem to

    have this data.
