1. The Marine Biome
It’s Deep...

2. The Marine Biome The largest of all the Biomes
More than (>) 70% of the Earth’s surface is covered in water. Only 3% is fresh.
Ice 2% Lakes, Rivers and Atmosphere = 1%
Average depth is 3800 meters
About 2.4 miles
Deepest is 11,045 meters
Mariana Trench

3. The Marine Biome
The Marine Biome is broken into two major groups of zones.
The Benthic Zones
Underwater Land
The Pelagic Zones
The Water columns

4. The Benthic Zones Underwater Land Continental Shelf zone. Bathyal zone
Also the edge, slope and rise zones
Bathyal zone
Between 200 and 2,000 m ( ,600 feet) below the surface.
Abyssal zone
Dark ocean region 2,000–6,000 m(6, ,500 feet) deep

5. The Benthic Zones Hadal zone The Trenches
The deepest region of the oceans (greater than > 6,000 m)
The French meaning is "house of the dead".
The Trenches
Mariana Trench
The deepest known is at 10,911 m.(6.8 miles)

7. The Pelagic Zones The Water columns The Neritic zones
Above the Continental Shelf to the Shore
The Oceanic zones
Everywhere else

10. Prepare yourself...
You need to write a staggering 23 words for the next three slides!

11. The Pelagic Zones
The oceanic pelagic region is divided into three sunlight zones.
The top zone is the euphotic or sunlit zone. This is the ocean zone that sunlight penetrates.
Down to about 660 feet

12. The Pelagic Zones
The pelagic region is divided into three sunlight zones.
The next zone is the dysphotic or twilight zone. Some sunlight reaches this zone, but not enough for photosynthesis to occur.
Down to about 3,300 feet.

13. The Pelagic Zones
The pelagic region is divided into three sunlight zones.
The last zone is the aphotic or midnight zone.
No light, pure saturating darkness….down to the very pit of the festering abyss.
Bwaa Haaa Haaa Haaa!

15. And now…..
Something completely different!
With 31 and a & words.

16. Estuaries
An estuary is a partially enclosed body of water where incoming seawater is mixed with fresh water coming from the land.
Like a salt marsh…for example..
And what is good about a salt marsh? CD

17. Estuaries A Water Filtration System Flood & Storm Control
River sediment (and pollution) trapped.
Flood & Storm Control
Hugely absorptive of water..buffer for swells and tides
Extremely productive.
