A researcher needs estimates of current speed and direction from an instrument operating in the water. How does an acoustic Doppler current profiler obtain these estimates?

A
It uses sound reflected from particles in the water to estimate current speed and direction.
B
It uses satellite images to measure seafloor plate movement.
C
It collects water samples and analyzes their chemical composition.
D
It uses cameras to count organisms in deep-water habitats.

A research team wants to determine whether an observed ocean pattern represents lasting change rather than short-term variation. Which approaches support a reliable interpretation? Select all that apply.

A
Repeat observations to distinguish short-term variation from lasting change.
B
Compare data collected by different platforms.
C
Consider measurement uncertainty when interpreting the observations.
D
Assume that each instrument captures every relevant ocean condition.

A change in one ocean region may affect weather or climate far away. Which explanation best accounts for this connection?

A
The seafloor blocks all exchanges between the ocean and atmosphere.
B
Ocean currents affect only the locations where they originate.
C
The ocean stores and redistributes heat, and currents transport heat and water around the planet.
D
The ocean influences climate only through its dissolved materials.

A
They replace the need to collect observations from any other platform.
B
They extend exploration into places that are difficult or unsafe for people to reach.
C
They are used only to observe the ocean surface from space.
D

Which statement best explains how the ocean’s role in handling heat can influence conditions beyond the region where that heat is absorbed?

A
It only reflects heat back to the atmosphere and has little influence on climate.
B
It absorbs, stores, and redistributes heat, influencing weather and climate.
C
It affects climate only through direct contact with land.
D
It prevents heat from moving between the ocean and atmosphere.
