Deep Ocean Drop Cam Expedition

The video tutorial introduces the use of deep ocean drop cams by National Geographic's remote imaging group. It highlights the collaboration among scientists collecting various data types and the exploration of the deep ocean, which remains largely unexplored. The process of preparing, deploying, and recovering the drop cams is detailed, including the use of bait and LED lights to attract marine life. The tutorial concludes with the analysis of footage, revealing new discoveries in marine biology.

What is the primary purpose of the deep ocean drop cams used in the expedition?

• To track ocean currents

• To communicate with submarines

• To capture images of marine life on the ocean floor

• To measure ocean temperature

How do scientists plan to use the data collected from different groups during the expedition?

• To predict weather patterns

• To create a map of the ocean floor

• To develop new fishing techniques

• To understand the movement of organisms in the water column

What is the purpose of using bait with the drop cams?

• To anchor the camera to the ocean floor

• To test the camera's durability

• To attract fish into the camera's frame

• To measure water salinity

What mechanism is used to release the drop cam's weight in the ocean?

• A mechanical lever

• A remote-controlled switch

• A burn wire that corrodes in the ocean

• A timer-based release

What tool is used to locate the drop cam after it surfaces?

• A satellite phone

• A radio receiver

• A sonar device

• A GPS tracker

What is the significance of the orange flag in the recovery process?

• It indicates the depth of the ocean

• It marks the location of the drop cam

• It signals the end of the expedition

• It is used to measure wind speed

What is the next step after recovering the drop cams?

• Conducting a team meeting

• Repairing the cameras

• Charging the batteries and downloading footage

• Analyzing water samples

What type of shark was identified in the footage below 1,000 meters?

• Lantern Shark

• Hammerhead Shark

• Great White Shark

• Tiger Shark

Why is the discovery of new marine life exciting for the team?

• It confirms existing marine theories

• It provides insights into uncharted territories

• It helps in developing new fishing methods

• It allows for better ocean navigation

What is the main challenge in predicting what the drop cams will capture?

• The cameras often malfunction

• The ocean currents are unpredictable

• The deep ocean is largely unexplored

• The bait does not always attract fish
