Marine BiomeHeechae ChonAntonio MiresMauricio LauRafael Wille
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
1)Climate and Limiting Factors
ABIOTIC FACTORS BIOTIC FACTORS
Sand Seaweed
Grains Fish
Wind Mammals
Water Particles Bacteria
Precipitation Plankton
Current
Underwater caves
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
