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

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 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
