Sea water is a mixture of various types of salt and water. There is also chlorine, sodium, sulfur, magnesium, calcium, and potassium that are in the sea salt.
Station 3: Water Mass Identification Using T-S Diagrams
1.
In
the CTD profile you plotted, the deepest water had the lowest salinities.
Explain how this is possible. Hint: Remember that more than salinity affects
water density.
2. Normally you find high salinities at
the surface of the water, especially in samples taken closer to the equator.
Explain.
3. Why would scientists be interested
in identifying specific water masses?
Station 4: Factors affecting Salinity
1.
Examine
the transect line and your plotted graph and explain what causes the salinity
changes from the equator to the Bering Sea in the Arctic Circle.
2. Research what other factors can
alter the salinities in the ocean from its average of 35‰.
Conclude and Communicate:
1.
Write
two new research questions based on what you have learned from this activity.
2. The value and importance of this
activity:
a. What is the unique chemistry of
seawater, how is it measured, what is its consistency and what are its physical
characteristics?
b. Why would scientists be interested
in the inorganic chemistry of water?
