Presentation on theme: "Ocean Zones (shoreline to open ocean)"— Presentation transcript:

1 Ocean Zones (shoreline to open ocean)
Intertidal Zone Neritic Zone Open Ocean Zone Benthic Zone

2 Intertidal Zone Neritic Zone Open Ocean Zone Continental Shelf
Sunlight Continental Shelf Benthic Zone

3 Intertidal Zone Area between high tide line and low tide line
Organisms adapted to harsh, changing environments Intertidal Zone Continental Shelf

4 The Impact of the Intertidal Zone

5 Neritic Zone Area over the continental shelf
Area of greatest density and diversity of marine life Neritic Zone Continental Shelf

6 Open Ocean Zone From the continental break out to open ocean
Shelf

7 Benthic Zone The Ocean Floor Underlies all the other zones

8 Lifestyles 3 Basic Lifestyles: Plankton Nekton Benthos

9 Ocean Lifestyles

10 Plankton Floaters or very poor swimmers
Plankton divided into 2 groups: Phytoplankton – producers, photosynthesizers Zooplankton – consumers

11 Phytoplankton Must live in the photic zone
Most abundant in shallow coastal areas or in upwelling zones The basis of the oceanic food web

12 Zooplankton Foraminifers Radiolarians Cnidarians Combjellies
Arthropods Larvae

13 Zooplankton

14 Nekton (swimmers) Free swimmers Maneuver actively in the water column
Found in the water column from surface to ocean floor

15 Nekton (swimmers) 5 Categories: Reptiles Mammals Fish Arthropods
Mollusks

16 Nekton (swimmers) Marine Reptiles: Turtles Snakes Crocodiles Iguanas

17 Nekton (swimmers) Marine Mammals: Whales Seals Otters Manatees
Dolphins

18 Nekton (swimmers) Bony Fish: Tuna Barracuda Eels Angler Fish

19 Nekton (swimmers) Cartilaginous Fish Sharks Rays Skates Chimaeras

20 Nekton (swimmers) Marine Arthropods Shrimp Mollusks Squid Octopi

21 Benthos (bottom dwellers)
Live either burrowed in, resting on, or attached to the bottom Primarily filter feeders, scavengers or deposit feeders

22 Benthos (bottom dwellers)
2 Basic Types: Sessile - Live attached to the bottom Vagrant - Able to move about

23 Benthos (bottom dwellers)
Sessile: Barnacles Sponges Corals Sea Anemones Oysters Clams

24 Benthos (bottom dwellers)
Vagrant: Crabs Sea Stars Sea Cucumbers Sea Urchins Brittle Stars

25 Now what do you think?? Hmmmm…

34 Which mapping technology would you use?
Intertidal Zone Snorkel GPS (satellites) Neritic Zone Scuba Diver Open Ocean Zone Submarines Sonar Benthic Zone Submersibles R.U.M.s (robots)
