What type of ocean exploration technique is the best for determining potential oil and gas reservoirs?

Ocean depth is calculated by the time it takes sound waves to travel from the ship to the seafloor and back to the ship again. What type of ocean exploration technique is the best for determining potential oil and gas reservoirs? Seismic reflection survey.

What is Seamount quizlet?

What is a seamount? An active volcano that occurs along the crest of the mid-ocean ridge. … Seamounts subside as tectonic plates move. Coral reefs grow away from the seamount in order to stay near the sunlight.

What is the depth of the ocean if a sonar signal takes 6 seconds to be sent and received back?

If it takes the sound 6 seconds to get to the floor and back then it takes 3 seconds to reach the floor. So all you would need to do multiply (3 seconds) x (the speed of sound in water) = distance to sea floor.

What are 4 ways scientists study the ocean floor?
