Marine Biomes: What?Marine regions cover about ¾ of the Earth’s

surface.

They provide much of the world’s oxygen supply

Marine regions include subsets of this biome like:OceansCoral ReefsEstuaries

Where is the Marine Biome?

Divided into 7 major bodies of water:Pacific, Atlantic, Artic, Indian, Southern

The ocean ecosystem, the largest within the marine biome, is separated into: Intertidal zone: where ocean meets landPelagic zone: Open oceanBenthic zone: Below open oceanAbyssal zone: Deep ocean

Salinity

2)Climate and Limiting Factors

The saltiness of water prevents ocean from freezing

The nutrient count in shallow waters produces a very rich ecosystem and inversely. Light Oxygen Temperature Salinity Food Space pH (acid or basic) Nutrients and Nitrates

Biotic and Abiotic Factors

Attributes - Arctic Ocean Top Layer (50m), low salinity

and temperature

Freshwater input of big Siberian and Canadian streams

Fragile ecosystem, slow to change and recover

Little plant life, except for phytoplankton

Natural resources: petroleum and natural gas fields, placer deposits, polymetallic modules, sand and gravel aggregates, fish, seals, and whales

Typical Primary and Secondary Consumers

Primary Consumer

Artic Cod (Arctogadus Glacialis)

Diet: small crustaceans, such as shrimp and amphipods

Predators: Harp seal, killer whale and baleen whale

Secondary Consumer

Harp Seal (Pagophilus Groenlandicus)

Diet: Mostly herring, capelin and cod

Predators: Walruses, polar bears, and killer whale
