1. April 20th/21st Notes 12.a: Ocean Zones

2. Life in the ocean is extremely diverse & unevenly distributed.
TODAY’S TARGET: I can determine where life in the ocean can be found.
Life in the ocean is extremely diverse & unevenly distributed.
World ocean copepod diversity (D) (log of taxonomic richness, see vertical scale bar) predicted from ocean temperature (T), salinity (S) and chl a (C) using the equation: D = T  S − C (environmental variables were gridded on 1° longitude × 1° latitude).

3. Life in the ocean is extremely diverse & unevenly distributed.
TODAY’S TARGET: I can determine where life in the ocean can be found.
Life in the ocean is extremely diverse & unevenly distributed.
The ocean’s great age
Enormous water volume
Intervening seas with land masses
Historic stability of environment
Specialization on particular sediment types and in different water depths

4. TODAY’S TARGET: I can compare and contrast various methods used to divide the ocean into habitats using target vocabulary.
One way to subdivide the ocean is to separate the __________ (benthic) from the ____________ (pelagic).
sea bottom
water column

5. Pelagic (i.e., water column areas) Neritic Oceanic
TODAY’S TARGET: I can compare and contrast various methods used to divide the ocean into habitats using target vocabulary.
Pelagic (i.e., water column areas)
Neritic
Oceanic
Shallow part of sea near coast
Far from shore open ocean area
Neritic – shallow part of the sea near the coast or above the continental shelf

8. Practice with cards in class Work in groups of 2-3 Pelagic and Benthic
TODAY’S TARGET: I can compare and contrast various methods used to divide the ocean into habitats using target vocabulary.
Practice with cards in class
Work in groups of 2-3
Pelagic and Benthic
How do you divide the benthic? (6)
How do you divide the pelagic? (2)
Which one of those is subdivided more?
How?

9. TODAY’S TARGET: I can compare and contrast various methods used to divide the ocean into habitats using target vocabulary.
Another way of dividing the ocean relies on illumination. Here the ocean is divided into the:
Photic zone
Aphotic (midnight)
Euphotic (sunlight)
Disphotic (twilight)

12. TODAY’S TARGET: I can label an ocean cross section diagram using target vocabulary.
Homework: Ocean zones mural label these 15 terms (with correct names) on a piece of paper. Cut out an ocean floor and glue onto paper.
Due April 26th.
