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.

The Marine biome is found in 5 main oceans: the Pacific, the Atlantic, the Indian, the Arctic, and the Southern ocean. The marine biome is found on every continent. The two largest bodies of water in the world are the Pacific Ocean and the Atlantic Ocean.
The adaptive capacities of marine and coastal ecosystems varies among species, sectors, and geographical regions. In the broader oceans, marine organisms will be relatively free to move to new geographical areas; organisms in enclosed seas and coastal zones are more constrained by the physical features
The benthic zone is home to a massive amount of oceanic life referred to as “benthos”, or bottom-dwellers. Out of all marine species, 98% of them can be found on the ocean floor, making the benthic zone the lifeblood of diversity in the ocean, comprised of mostly scavengers or detritivores, organisms that feed off of dead organic material.
This chapter assesses the impact of climate change on the full spectrum of ocean and coastal ecosystems, on their services and on related human activities, and it assesses marine-related opportunities within both ecological and social systems to adapt to climate change.
24 Οκτ 2024 · Marine ecosystem, complex of living organisms in the ocean environment. Marine waters cover two-thirds of the surface of the Earth. In some places the ocean is deeper than Mount Everest is high; for example, the Mariana Trench and the Tonga Trench in the western part of the Pacific Ocean reach.
