Part One -

1. What is the warmest temperature in the ocean? (answer to the nearest whole degree)

2. Which part of which ocean basin consistently contains the warmest water in the ocean (note this part of the ocean remains red and dark red permanently)?

3. In what month is the tropical ocean the hottest? (write the name of a month in the box in full (i.e. January instead of Jan)

4. What is the coldest temperature in the surface ocean? (answer to the nearest whole degree)

5. Where is the coldest surface water (in the part of the ocean illustrated)?

Part Two -

1. Where is the saltiest water in the ocean (hint: it is not in a major ocean basin)? Why?

 2. What locations are characterized by the freshest water in the Atlantic Ocean? Why (think about the processes that impact surface ocean salinity)?

3. Are equatorial locations generally associated with fresher or saltier water? Why (again think about the processes that impact surface ocean salinity)?

Part 3 -

As we have seen, temperature and salinity combine to determine the density of a water mass. Look at this map of ocean density and answer the following questions.

1. In what locations is the lightest water in the oceans found? Why (think about the processes that impact the density of a water mass)?

2. In the northern hemisphere what locations is the highest density in the oceans found? Why (think about the processes that impact the density of a water mass)?

Part 4 -

1. Where are the highest nutrient levels found in the Northern Hemisphere? Why (think about the processes that impact the nutrient content of a surface water mass)?

2. Where are the lowest nutrient levels found? Why (think about the processes that impact the nutrient content of a surface water mass)?

Part 5 -

1. Calculate the density of the water masses off the coast of Florida with a temperature of 24^oC and a salinity of 35 ppt and off the coast of Norway (temperature of 8^oC and salinity of 35 ppt). Make sure to record your values for temperature and salinity. You can use Water Density Calculator for the density calculation. Temperature values can be entered directly. Salinity values are in parts per thousand and must be converted to parts per million before entry (you will get wrong answers if you don't!).(Answer to 3 decimal places e.g. 1.234)

2. Which of the locations has the highest density and is therefore the most likely to form deep water?

3. Is this result what you expected from what you have learned about deep water circulation?
