  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. • Also the edge, slope and rise zones • Bathyal zone • Between 200 and 2,000 m (660 - 6,600 feet) below the surface. • Abyssal zone • Dark ocean region 2,000–6,000 m(6,500 - 19,500 feet) deep

  5. The Benthic Zones • Hadal zone • 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

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

  9. 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

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

  11. 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!

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

  13. 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

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

  15. Euphotic Zone (in Green) Neritic Oceanic zones Dysphotic Zone The Pelagic Zones (water zones separated by light penetration) Aphotic Zone Continental Shelf Bathyal Abyssal Hadal Trenches The Benthic Zones (Underwater lands)
