Question
Chapter 3, Problem 1CT
Summary Introduction
To predict: The salinity of the Adriatic Sea.
Introduction: The amount of dissolved salts (sodium and chlorine) in sea water is called ocean salinity (saltiness). It is usually measured in practical salinity unit (PSU).
Expert Solution & Answer
Explanation of Solution
In abnormal cold winters, the Black Sea may sometimes freeze whereas the Adriatic Sea does not freeze. The Black Sea has a low salinity of about 18 psu. The Adriatic Sea has salinity much greater than Black Sea. It usually varies between 38–39 psu in the south to 33–25 psu in the north.

- Another motion of surface water are ocean currents. Ocean currents are like rivers of water moving through other seawater. These can also be caused by prevailing winds. The worldwide prevailing winds causing great circular moving water in the ocean called gyres. Another type of current is caused by the waves washing up on the shore at an angle, but the water then running back down the shore in a straight line. So you have this process of water going up onto the shore at an angle and then straight back down the face of the shore. Resulting in the water moving along the shore in a zig-zag pattern. As this is repeated thousands of times a day, the effect is a current (movement of water) is formed that moves parallel to the shoreline. This current is called a longshore current. There is another current that runs along the coast of California called the California current. An amazing animal travels along this current during its annual migration. In the fall, this animal travels from its…arrow_forwardWhy is the pH found in freshwater sources in the Eastern half of the United States dramatically lower than that found in the western half?arrow_forwardPollutant released due to human activities (like effluents from industries and homes) can radically accelerate the ageing process of the water body .(a) Explain how does this process occurs during natural ageing of lake.(b) Give the term used for accelerated ageing of water bodies.

- A city’s sewage outfall flows 40 ft3/s of sewage with a BOD concentration of 30 mg/L anda DO of 1.5 mg / L into a small river that has a flow rate of 280 ft3/s and a velocity of 1.1 ft /s.The river has a natural BOD of 3.5 mg/L and at this time of year the DO level is 7 mg/L. Giventhe water temperature this time of year the DO saturation is 8.5 mg / L.
