Ocean Exploration Technologies and Techniques

The video tutorial explores technologies used to study the ocean floor, focusing on the sounding pole. It demonstrates how to collect and analyze ocean depth data using a depth data grid. The tutorial highlights the limitations of the sounding pole and discusses potential improvements, such as using sonar and cameras. The video emphasizes the importance of understanding the ocean floor for navigation and scientific research, noting that only 5% of the ocean has been studied.

Which technology was historically used to understand the ocean floor's structure?

• Sonar

• Sounding Pole

• Radar

• Satellite Imaging

What is the primary purpose of using a sounding pole?

• To determine ocean depth

• To detect marine life

• To measure water temperature

• To map ocean currents

In the model ocean activity, what does a '7' represent?

• A rocky area

• The shallowest part

• The deepest part

• A sandy area

What does the model ocean activity help students understand?

• The speed of ocean currents

• The depth variations of the ocean floor

• The temperature of the ocean

• The types of marine life

What was a key limitation of the sounding pole identified during the activity?

• It could not measure temperature

• It was difficult to use

• It was too expensive

• It missed many features on the ocean floor

What do the ping-pong balls and tennis balls represent in the model ocean?

• Ocean currents

• Marine animals

• Unseen features on the ocean floor

• Temperature variations

What advanced technology is suggested for better ocean floor exploration?

• Lidar

• Sonar

• Radar

• Infrared Imaging

How much of the ocean has been explored according to the video?

• 75%

• 10%

• 5%

• 50%

What is one suggested improvement for the sounding pole?

• Attaching a camera

• Using a longer pole

• Making it lighter

• Adding a GPS

Why is sonar considered a better technology than the sounding pole?

• It provides more detailed data

• It is easier to use

• It covers a larger area

• It is cheaper
