  1. Marine Ecosystems

  2. Warm-Up • Write your homework – leave it out to be stamped • Update your Table of Contents for today! • REVIEW: What is an ecosystem? What are biotic & abioticfactors? What are water ecosystems called? Land ecosystems? How can they be connected? • Our focus today is marine ecosystems…what does marine refer to?

  3. Intertidal Zone • Shoreline area that falls between the high tide and low tide mark.

  4. Life in the Intertidal Zone • Animals in this area are able to adapt to being both underwater and in open air Common Life Forms: • Crabs • Urchins • Starfish • Clams • Snails • Mussels

  5. Neritic Zone • The ocean zone that slopes down from the shoreline towards the ocean floor.

  6. Life in the Neritic Zone • Animals in the Neritic Zone have access to both shallow and deeper water. The life in this zone is very diverse! Common Life Forms: • Sea Turtles • Dolphins • Seals • Variety of fish

  7. Oceanic Zone • The oceanic zone is made up of the open waters of the ocean

  8. Life in the Oceanic Zone • Marine life varies greatly due to the changes in depth, temperature, pressure and amount of sunlight. Common Life Forms: • Whales • Sharks • Squid • Angler Fish (deep)

  9. Intertidal zone Neritic zone Oceanic zone

  10. Marine Ecosystems: • Within these zones are many different and separate ecosystems.

  11. Coral Reefs • Extremely diverse ecosystems - “The Rainforests of the Ocean,” are sensitive to change and protect coastlines from storm surges

  12. Estuary • An area where fresh water from a river mixes into the salt water of the ocean creating “brackish” waters

  13. Estuary Demo • Salt Water is denser than freshwater therefore it does not fully mix…watch what happens in our mini estuary

  14. Kelp Forests • Large underwater forests of brown algae that provide a habitat for animals and many resources for humans

  15. Kelp Forests http://oceantoday.noaa.gov/underwaterforests/ http://oceantoday.noaa.gov/seaotterkelphumans/welcome.html

  16. Salt Marshes • A transitional area between land and water that acts like a filter for pollution

  17. Mangrove Forests • A transitional area between land and water in tropical areas that transfer energy from land to sea through the food chain

  18. What About the Deep Ocean Ecosystem? • http://ocean.si.edu/ocean-videos/deep-ocean-explorers • What are some characteristics of the deep ocean ecosystem and the organisms within it?

  19. What Is Ocean Life Like? Investigate what makes the ocean so unique by taking a “Vocab Swim” through the ocean’s… • Features & Zones • Nutrients & Processes • Physical Conditions • More Unique Ecosystems • Essential Organisms

  20. The Ocean as a Resource… What is the value of marine ecosystems…what do we get from them and what do we use them for? http://www.youtube.com/watch?v=euY7vdM5mpE http://www.youtube.com/watch?v=SuW__C9wLPQ
