Google 3 ways that the ocean is divided into zones.

6. Marine Science: Unit 3 – Ocean Zones and Ocean Chemistry

7. Part 1 – Ocean Zones Student learning goals for part 1 include;
Students will be able to .. .
Describe the types of ocean zones, the physical characteristics of each zone and determine the type of organisms that live there.
Describe the limitations and adaptations needed for organisms to live in each ocean zone
Explain how changes to an ecosystem like climate change, seasonal variation, and succession can affect populations in an ocean zone.

8. Zones are differentiated based on different properties
These properties are as follows:
Water or Bottom
Near Shore or Offshore
Light Availability
Ocean Depth

9. ● The zones exist only in our minds and on paper as a way to study different characteristics of different areas of the oceans ● Just as the different oceans are not separated by any boundaries, neither are the zones in the ocean ● Animals pass through the zones readily without any actual borders to stop them ● These zones can differ depending on what information you view so you are only responsible for what you learn in this class

10. A. Pelagic (water) or Benthic (bottom)

11. Pelagic Benthic The sea floor at all depths
The water column above the bottom
Organisms that live in this zone swim or drift
It can be from the ocean’s surface to the deepest waters
The sea floor at all depths
Organisms that live here generally don’t swim well or are sessile
It can be on the ocean floor from where the waves break to the trenches

12. Benthic or Pelagic?

19. B. Neritic (nearshore) or Oceanic (offshore)

20. Neritic Oceanic
From where the tide comes up out to the edge of the continental shelf
From the continental shelf all the way across the ocean to the other continental shelf

22. Neritic or Oceanic?

27. C. Light Availability
Photic Zone – Surface of ocean down to about 100 meters
Greek, photic means “lit”
Disphotic Zone – Below photic zone from about 100 meters down to about 500 meters
Greek, disphotic means “poorly lit”
Aphotic Zone – Below disphotic zone from about 500 meters down to the bottom
Greek, aphotic means “without light”
90% of the ocean is in the aphotic zone!!

28. Photic, Disphotic or Aphotic?

33. D. Ocean Depth Epipelagic - “Surface” Mesopelagic – “Middle”
Bathypelagic – “Deep”
Abyssalpelagic – “Bottomless”
Hadalpelagic – “Unseen”

34. Epipelagic Zone 90% of all ocean life lives here.
This is the only zone where photosynthesis occurs.
This zone contains the most important organisms in the ocean!!!!
Guess what they are.
Why do you think they are the most important organisms?

35. Mesopelagic Zone Food is scarce, and mostly falls from above.
There is enough light from above that animals need camouflage, but not enough for photosynthesis.

36. Bathypelagic Zone Deep Dark Cold Food is very scarce
Water pressure is immense, reaching 5,850 pounds per square inch.
In spite of the pressure, a surprisingly large number of creatures can be found here
Most of the animals that live at these depths are black or red in color due to the lack of light.

37. Abyssalpelagic Zone
Three-quarters of the ocean floor lies within this zone.
Deeper
Darker
Colder
Even less food
The water temperature is near freezing.
The deepest fish ever discovered was found in the Puerto Rico Trench at a depth of 27,460 feet (8,372 meters).

38. Hadalpelagic Zone Deepest Darkest Coldest The trenches
The deepest point in the ocean is located in the Mariana Trench off the coast of Japan at 35,797 feet (10,911 meters).
Temperature of the water is just above freezing, and the pressure is an incredible eight tons per square inch.
That is approximately the weight of 48 Boeing 747 jets.
In spite of the pressure and temperature, life can still be found here. Invertebrates such as starfish and tube worms can thrive at these depths

39. Copy the picture below

41. Video clips on Ocean Zones
Deep Sea Exploration
Why is the ocean blue?
Why are oceans salty?

42. Opening Assignment Day 3
List the following zones in the correct order AND tell me what the prefix means
Hadalpelagic
Epipelagic
Abyssalpelagic
Bathypelagic
Mesopelagic
