3. Other Surface Waters What is a wetland?
An area where the water table is at, near or above the land surface long enough during the year to support adapted plant growth
What are the types of wetlands?
Swamps, bogs, and marshes
Swamp: a wetland dominated by trees
Bogs: a wetland dominated by peat moss
Marshes: a wetland dominated by grasses

6. Technology and the Hydrosphere
Remote Sensing - allows scientists to use satellites to monitor all areas of Earth
Hundreds of km above Earth’s surface
Detects changes in light and energy that are not visible to the human eye
Computers can covert to colors
Example: temperature

7. Technology and the Hydrosphere (con’t)
Remote Sensing (con’t)
Uses:
Amounts and location of phytoplankton
Amounts of dissolved organic compounds
Location and amount of sediment
Temperatures (predict El Nino)
Buoys can be used to record temperatures, winds, currents, and air temperatures

8. Ground Truthing
The information gathered on the GROUND to verify remote-sensing information.

9. Technology and the Hydrosphere (con’t)
GPS (Global Positioning System) – uses satellites to pinpoint locations on Earth
Calculates latitude and longitude at 3 or more sites

10. Technology and the Hydrosphere (con’t)
GIS (Geographic Information Systems) – mapmaking software that creates different map layers for the same area
Each layer contains different information
Example: Mapping a Watershed would include different layers, each showing something different like temperature, nitrate levels, pH, dissolved oxygen, pollution
Using all the layers, the location of possible polluters can be determined
