Dear Alex,

I advice you to see this work: "Ocean yearbook, 27. Dalhousie University, Leiden (2013)" its a very interesting publication in this field, and especially the chapter of Spalding et al. "Protecting Marine Spaces: Global Targets and Changing Approaches" this one is available online from: http://www.cbd.int/doc/meetings/mar/cbwsoi-seasi-01/other/cbwsoi-seasi-01-protecting-marine-spaces-en.pdf

I hope this can be helpful. Good luck.

For the US anyway that is all recorded on the NOAA site. See the map here:

Dear Alex, Integrated coastal zone management, coastal aquaculture authority may able to provide this king of information.

Try the World Database on Protected Areas for all the data you could possibly hope for.

http://www.wdpa.org

And their most recent report.

Thank you all for these useful suggestions. I found the Spalding chapter particularly useful Ibrahim, there was a lot of relevant information in there for a paper I'm trying to write. Thanks again!

You are welcome Alex ;)
