Like pelagic surface waters, this habitat layer is well mapped, though slight inaccuracies may have been introduced by errors in the bathymetry along the 60 m depth contour. Surface and deep pelagic water habitats are completely overlapping in the horizontal dimension. What happens in the vast stretches of the world's oceans - both wondrous and worrisome - has too often been out of sight, out of mind. The sea represents the last major scientific frontier on planet earth - a place where expeditions continue to discover not only new species, but even new phyla. The role of these species in the ecosystem, where they sit in the tree of life, and how they respond to environmental changes really do constitute mysteries of the deep. Despite technological advances that now allow people to access, exploit or affect nearly all parts of the ocean, we still understand very little of the ocean's biodiversity and how it is changing under our influence. The goal of the research presented here is to estimate and visualize, for the first time, the global impact humans are having on the ocean's ecosystems. Our analysis, published in Science February 15, 2008, shows that over 40% of the world's oceans are heavily affected by human activities and few if any areas remain untouched.
