How Deep?

Read all of the things below, and watch my video at the bottom of this if you don't understand how to do this!

Using the Deep Sea website below, please choose one animal from each pelagic zone listed. As you scroll down through the page, you will see a white line showing you how deep you are. The zones are: 

Epipelagic (0-200 m)

Mesopelagic (200-1000 m)

Bathypelagic (1000- 3000m)

 In a Google Slides presentation, please build one slide per animal and tell me:

1. Animal's common and scientific name and a picture

2. Where  specifically in the world is it found (which ocean basin, or all ocean basins)

3. Its maximum depth (that is where it is found on the webpage: at its deepest. So, it technically lives in the zone above its picture!)

4. How many atmospheres of pressure are at that depth (take the meters of depth, divide by 10, add 1)

5. Which density zone it is in: Surface, Pycnocline, or Deep

So, to recap: you will have 3 slides, one animal from each pelagic zone.

There is a reason Fravel doesn't teach math. I didn't explain how to calculate how many atmospheres of pressure at depth. 

• At the surface, there is 1 atmosphere (atm) of pressure already.
• Every 10 meters under the water exerts an additional atmosphere
• So, take the number of meters, divide by 10 and add 1 to get the atmospheres at that depth.
• EX: at 200 meters, there is 200/10=20 atm of water, plus 1 atm, so 21 atm pressure. 
  • (If you are a scuba diver, this is different from "gauge pressure", which doesn't count the surface atmosphere. )

Sorry, carry on.
