Welcome to Weather, Climate, & the Oceans!
Why did you decide to take this class?
What are you interested in learning about?

4. Who am I?
Ms. Mueller
I teach Biology, Weather & Climate, and Space Science
Three things about me… 1. I love music.
2. I speak German.
3. I love the Badgers!

5. Unit 1: The Oceans Seafloor Mapping/Bathymetry Salinity
Seafloor Sediments
Ocean Thermohaline Currents
Oceanic zones & life

6. Where are the oceans? 5 oceans:
Pacific, Atlantic, Indian, Arctic, Southern

8. That being said…
It is important to remember that our oceans are all connected to form 1 “World Ocean”.

9. Distribution of Land vs. Water

10. Pacific Ocean is the largest basin

11. What is at the bottom of the ocean?

12. Ocean Topography
Topography: description and arrangement of physical pieces of a landscape

13. …how do we know?
Bathymetry = measurement of ocean depths and charting of shape or topography of the ocean floor
Sonar
SOund NAvigation and Ranging
transmits sound waves toward the ocean bottom and then intercepts the echo reflected, and a clock measures the time interval

14. Single Beam vs. Multi-beam Sonar
Single beam: one sound signal from one source
Multi-beam: many sound signals from one source

15. Satellite Altimeter measures the topography of the oceans surface
The ocean floor affects the topography of the ocean surface

16. Two Views:
Transect— “side view”
Relief— “top view”… shows depth by colors

17. Bathymetry Lab Work with a partner Obtain an “Ocean Floor” box
Follow the directions on the lab to figure out what the bottom of your Ocean Floor looks like

18. How much do we know about the bottom of the ocean?
Not much!
“To date, we have explored less than five percent of the ocean.” --NOAA
WHY?

19. “Just how little do we know about the ocean floor?”
Something you found interesting
Something you found confusing
Something you have a question about

20. Exit Slip Where do you prefer to sit? (Front, back, middle, side, ect)
With regard to Oceans—what are you interested in learning about?
