Humans often aggregate near coastal habitats to take advantage of ecosystem services. For example, coastal capture fisheries from mangroves and coral reef habitats are estimated to be worth a minimum of $34 billion per year. [64] Yet, many of these habitats are either marginally protected or not protected.
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.

Marine habitats can be broadly divided into pelagic and demersal habitats. Pelagic habitats are the habitats of the open water column, away from the bottom of the ocean. Demersal habitats are the habitats that are near or on the bottom of the ocean. An organism living in a pelagic habitat is said to be a pelagic organism, as in pelagic fish.
The refuge protects various kinds of habitat, including barrier beach, dune, tidal estuary, salt marsh, and rocky coastline. [ 2 ] However, it wasn't until the 1970s when the modern science of marine conservation would become first recognised; with undersea explorations equipped with new technologies, such as computers, being undertaken at the ...
By living in the Aquarius habitat and working at the same depth on the ocean floor, NEEMO crews are able to remain underwater for the duration of their mission. For NASA, the Aquarius habitat and its surroundings provide a convincing analog for space exploration. [2] Much like space, the undersea world is a hostile, alien place for humans to live.
Reef Life Survey provides data to improve biodiversity conservation and the sustainable management of marine resources. They collect and curate biodiversity information at spatial and temporal scales beyond those possible by most scientific dive teams which have to work with limited resources, by using volunteer recreational divers trained in the RLS survey procedures.
The Gulf Council was concerned about the effect that the removal of structures serving as artificial reef habitat may have on reef fish fisheries in the region. [39] Artificial reefs can be inhabited by federally managed species and may provide important habitat necessary to fish for spawning, breeding, feeding or growth to maturity. [40]
