What are some of the greatest challenges
associated with our water supply?
EnvironSci book p.293 - 298
What are some of the greatest challenges
associated with our water supply?
Access to Groundwater (Aquifers are recharged by Surface water)
Transpiration (Cottonwood & Willow trees suck up and evaporate water)
Competition for Use of water supply (agriculture, drinking water, septic system)
Agriculture Nitrates & Phosphorous (from fertilizers) Urbanization (population growth in cities draws more
groundwater)
S
Use a diagram to show the important
role that Aquifers play in our water
supply
Where does the majority of YOUR drinking water come from?

freshwater on earth found?
Where is your drinking water?

S
Where are the biggest reservoirs of freshwater on Earth?

What causes precipitation to
occur?
Explain what happened in the bottle.

What are the effects of El Nino?
El Nino
Where does the name “El Nino” come from?
Normal Pacific Ocean Currents
But every 4 - 12 years…
El Nino Pacific Ocean Currents
Is this a normal year? …or an El Nino year

IndonesiaNormal rain
South AmericaNormal rain
IndonesiaDrought!
South AmericaINTENSE Rain!
Ocean Nutrient upwelling
In terms of Nutrients, what does Ocean upwelling do off the coast of South America?
Ocean Nutrient upwelling
How does an El Nino year affect Nutrient cycling in off the coast of South America?

How do we collect this data?
http://www.pmel.noaa.gov/tao/jsdisplay/
What does normal climate look like around the
Pacific?
Purple = precipitationRed = surface temperatureBlue = nutrient Upwelling
What does climate look like during an El Nino year?
Purple = precipitationRed = surface temperatureBlue = nutrient Upwelling
S
How does El Nino affect precipitation
patterns, ocean temperatures, and nutrient upwelling?
S
How does El Nino differ from La Nina?
What does climate look like during a La Nina year?
Purple = precipitationRed = surface temperatureBlue = nutrient Upwelling
S
How does a La Nina year affect farmers
in South America and Indonesia?
