Marine biome

  1. 1. Marine Biome Heechae Chon Antonio Mires Mauricio Lau Rafael Wille
  2. 2. 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:  Oceans  Coral Reefs  Estuaries
  3. 3. 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 land  Pelagic zone: Open ocean  Benthic zone: Below open ocean  Abyssal zone: Deep ocean

  5. 5. 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
  6. 6. Biotic and Abiotic Factors
  7. 7. 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
  8. 8. Typical Primary and Secondary Consumers Primary Consumer Secondary Consumer Artic Cod (Arctogadus Glacialis)  Harp Seal (Pagophilus Groenlandicus) Diet: small crustaceans, such as shrimp and amphipods  Diet: Mostly herring, capelin and cod Predators: Harp seal, killer whale  Predators: Walruses, polar and baleen whale bears, and killer whale
  9. 9. Human activity in the ocean Sports Fishing Investigating
