Sample Practice Problem for Oceanography

Given the following data about the salinity of seawater, calculate the average salinity of the sample:

Sample 1: 35.5 ppt

Sample 2: 36.2 ppt

Sample 3: 34.8 ppt

Solution:

To calculate the average salinity, add the three samples together and divide by three.

35.5 + 36.2 + 34.8 = 106.5

106.5 / 3 = 35.5 ppt

Oceanography Quiz

Answer the following questions to test your knowledge of Oceanography.

Problem	Answer
What is the study of oceanography?	The study of oceanography involves the exploration and research of marine organisms, ocean currents, waves, and geology of the ocean floor
What are the 5 oceans of the world?	Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern Ocean, and Arctic Ocean
What is the Ring of Fire?	The Ring of Fire is a region around the Pacific Ocean where many volcanic eruptions and earthquakes occur
What is the difference between a sea and an ocean?	Seas are smaller bodies of saltwater that are partially enclosed by land whereas oceans are the vast bodies of saltwater that cover most of the Earth's surface
What is the Coriolis effect and how does it affect ocean currents?	The Coriolis effect is the apparent deflection of moving objects when viewed from a rotating reference frame, such as the Earth. The Coriolis effect causes ocean currents to move clockwise in the Southern Hemisphere and counterclockwise in the Northern Hemisphere
What is salinity and how does it affect the ocean's density?	Salinity is the concentration of dissolved salt in water. The higher the salinity, the denser the seawater
What is the thermocline and how does it affect marine life?	The thermocline is a layer of water in the ocean where temperature changes rapidly with depth. The thermocline affects marine life by creating a barrier that prevents the mixing of warm surface water and cold deep water, which can limit the amount of nutrients available for marine organisms
What is El Niño and how does it affect ocean conditions?	El Niño is a weather phenomenon that occurs when warm water in the western Pacific Ocean shifts eastward toward the South American coast. This can cause changes in ocean temperatures and currents, and lead to extreme weather conditions in different parts of the world
What causes ocean acidification and how does it affect marine organisms?	Ocean acidification is caused by the increased absorption of carbon dioxide into seawater, which decreases the pH level of the ocean. This can affect the ability of marine organisms, such as shellfish and plankton, to build their shells and skeletons, which can alter the ocean's food web
How does the ocean regulate Earth's climate?	The ocean plays a vital role in regulating Earth's climate by absorbing and storing large amounts of heat and carbon dioxide. The ocean's currents also transport heat from the equator to the poles, helping to distribute warmth around the planet

What is the Coriolis effect?	The Coriolis effect is the deflection of moving objects when they are viewed from a rotating reference frame. This effect is caused by the rotation of the Earth and is responsible for the formation of cyclonic storms.
What is the thermohaline circulation?	The thermohaline circulation is a global oceanic conveyor belt driven by temperature and salinity differences. It is responsible for the movement of heat around the world and is a major component of the global climate system.
What is the difference between a continental shelf and a continental slope?	A continental shelf is the shallow, gently sloping area of the ocean floor adjacent to a continent. A continental slope is the steeply sloping area of the ocean floor that lies beyond the continental shelf.
What is the difference between a coastal upwelling and a coastal downwelling?	A coastal upwelling is the process by which cold, nutrient-rich water is brought up from the deeper ocean to the surface. A coastal downwelling is the process by which warm, nutrient-poor water is brought down from the surface to the deeper ocean.
