Actual salinity varies among different marine ecosystems. [4] Marine ecosystems can be divided into many zones depending upon water depth and shoreline features. The oceanic zone is the vast open part of the ocean where animals such as whales, sharks, and tuna live. The benthic zone consists of substrates below water where many invertebrates live.
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.
As in many marine ecosystems, copepods represent a major food source for a variety of neustonic and surface-associated species. [ 1 ] The sea surface microlayer (SML) at the air-sea interface is a distinct, under-studied habitat compared to the subsurface and copepods, important components of ocean food webs, have developed key adaptations to ...
Scientists have identified several new marine species in a pristine underwater ecosystem recently discovered in international waters -- and they expect to find more. Modern technology that allows ...
The Mid Atlantic Bight's ecosystem can be seen as a transitional ecosystem between that of temperate and tropical ocean. Like the Gulf of Maine, it is an area of relatively high primary production. Much of the primary production in the Mid Atlantic Bight is in the summer and winter, and is highest near shore, and in estuarine environments.
The following is a list of marine ecoregions, as defined by the WWF and The Nature Conservancy. The WWF/Nature Conservancy scheme groups the individual ecoregions into 12 marine realms, which represent the broad latitudinal divisions of polar, temperate, and tropical seas, with subdivisions based on ocean basins.

Coral reefs deliver ecosystem services to tourism, fisheries and coastline protection. The global economic value of coral reefs has been estimated to be between US$29.8 billion [14] and $375 billion per year. [15] About 500 million people benefit from ecosystem services provided by coral reefs. [155]
