Summary

The worlds’ oceans and seas have tremendous potential to contribute to the provision of food, feed, energy and natural resources. The emerging concepts of “Blue Growth” and “Blue Economy” have put the development of new marine industries on the political agenda. As marine industries expand, spatial interconnections and industry boundaries are being drawn and the potential for the combined use of marine space is being explored. The aim of this paper is to provide a single source document that summarizes the probable boundaries of marine growth industries, namely aquaculture; offshore wind energy with fixed foundations; floating offshore wind energy; tidal and wave energy; marine biotechnology, seabed mining; and tourism and recreation, based on depth and distance from the shore. This is an important first step in developing a single source document for marine industry boundaries that will help marine spatial planners and researchers develop innovative industry combinations to foster growth in the marine sector. This paper explores marine industry overlaps in four basins: European Atlantic, Baltic/North Sea, Mediterranean/Black Sea and the Caribbean/ Gulf of Mexico. By describing the geographical characteristics of different sea basins, this paper helps to focus marine governance strategies for stimulating combinations of marine industries towards the most promising areas. The methodology developed in this paper was also used to generate 72 country-specific maps and corresponding tables to support marine spatial planning processes at a national level.
