The portal presents data from a variety of sources in a spatial way.

Our seas and coasts are an important natural resource. They support a wealth of wildlife and many commercially viable fisheries.

They contribute significantly to sectors of our economy such as tourism, ports, shipping, and alternative energy production.

Marine Protected Areas, where the important species and habitats are, help us to think about the possible impact our activities may have on these areas and how they may affect the wildlife that live there.

Our vision is for clean, healthy, safe, productive and biologically diverse oceans and seas.
