Marine protected areas (MPAs) now cover 8.2% of the world’s ocean. Human activities in these spaces are restricted or regulated to conserve marine ecosystems and resources. Satellites help identify, monitor, and manage these protected areas.
The image of Egg Island in the Bahamas shows the sharp contrast between the beautiful shallow turquoise waters to the southwest and the deeper darker Atlantic waters to the northeast. Ripples of sand waves created by currents stand out in the shallow waters, a natural nursery for sea turtles and other sea life.

The establishment of marine protected areas where human activities are limited or forbidden is fundamental for the protection of marine ecosystems and for restoring biodiversity. Furthermore, they boost tourism by providing new sustainable recreational activities. Satellite data provide constant, detailed, global information about marine protected areas and their characteristics, such as water temperature, water quality, habitat type, and coastline boundaries. They are also used to detect illegal activities and track the movement and distribution of species.
