Question 1  SEAWATER SAMPLE  TEMPERATURE (C) SALINITY (o/oo)

A                          15                    36

B                          22                 35

C                          17                   35

Given the temperatures and salinities of the three seawater samples above, enter the corresponding letter below to indicate the layering of these water masses if they were all found in the same ocean basin:

 

Top Layer  （         ）

 

Middle Layer （          ）

 

Bottom Layer  （           ）

Question 2 How did you determine the order of layers from Question 1?

Question 3 What are TWO different reasons why oxygen levels tend to be low in deep ocean waters?

Question 4 What are TWO ways that carbon dioxide affects marine organisms?

Question 5 What are the main factors that create the consistent global wind patterns shown in the figure above?

Question 6 What are the FOUR main factors that create ocean (not atmospheric) geostrophic currents? Briefly explain each one individually and also include how the FOUR relate to each other.

Question 7 What are the TWO main types of global ocean currents and what forces drive each one?

Question 8 WAVE     WAVELENGTH (m) WAVE PERIOD (s)

A             158                 12

B             40                    6.4

C                         89                 9.8

What is the speed (celerity) of each deep-water wave above? (Round to the nearest hundredths decimal place. Make sure to include units in your answer!)

 

Speed of Wave A (           )

 

Speed of Wave B (             )

 

Speed of Wave C (             )

 

Question 9 If all three waves in Question 8 passed through an area with a water depth of 4 meters, which (if any) of them would be considered a shallow water wave?

(    )Wave A

(     )Wave B

(      )Wave C

Question 10 Why do waves break when the reach shallow water? Also, how can you mathematically predict when a wave will break?

 

Above are the tidal predictions for Seattle, WA in January 2017

Question 11 Based on the chart above, what kind of tides do we experience in Seattle? What causes this type of tidal pattern?

Question 12 When are the spring tides (include specific dates)? How do you know?

Question 13 Do we experience high tide in Seattle, WA before or after San Diego, CA? How do you know?
