Nutrient Cycles:

Nutrient Cycles

• We are but stardust

2
Every atom within us is on a journey

• Odyssey part one by Aldo Leopold

3
Biogeochemical Cycles
How elements move through our planet
4
Other planets can move matter about
Great Red Spot on Jupiter
Wind Storms on Mars
Volcano on Io
5
but as the only planet that contains water in
its liquid state

• Earth is the only planet that can effectively
  move large amounts of solid material from one
  place to another.

6
Case in Point

• Encontras do Aguas, Manaus, Amazonas, Brasil

7
The Andes Mountains are washed away
8
So too are the Guinea Highlands
9
The Result
Sandy,quartz sediment
Silty, volcanic sediment
10
All washes down to the Atlantic Ocean
11
The Upshot
Underwater view of deep ocean sediment fan off
Amazon. Where were these sediments before?

Major Biogeochemical Cycles on Planet Earth

• Water (Hydrologic) Cycle
• Carbon Cycle
• Nitrogen Cycle
• Oxygen Cycle
• Sulfur Cycle
• Phosphorus Cycle

14
Water Cycle the driver for all other cycles
15
Carbon Cycle
16
LIFE LIMESTONE
17
Nitrogen Cycle
18
N-Cycle Aquatic Science application
19
Oxygen Cycle
20
Aquatic O cycle
21
Sulfur Cycle
22
Phosphorus Cycle
23
Why is it important that these cycles be kept in
balance?

• How do we throw them out of balance?

Aquatic Science Biogeochemical Review Game

• With 2-3 classmates, create the following
• - a board game that reviews the inputs,
  reservoirs, and outflows of each biogeochemical
  cycle.
• Must cover the movement of each cycle, the
  reservoirs, and anthropogenic effects.
• Game is due for teacher grade on Tuesday, 6
  September, 2011.
