5 Technologies Helping Us Explore The Deep Ocean

The video explores the vast and largely unexplored ocean depths, highlighting the challenges of underwater pressure and the technologies used to overcome them. It covers scuba diving limitations, the use of trimix gases, atmospheric diving suits, bathyscaphes, submarines, and remotely operated vehicles (ROVs). Each technology offers unique advantages for exploring different ocean depths, from recreational diving to the deepest parts of the ocean. The video emphasizes the importance of these technologies in discovering new species and understanding the ocean's ecosystems.

What is one of the main challenges of exploring the ocean?

• Lack of sunlight

• High water temperature

• Pressure increase with depth

• Strong ocean currents

Why are recreational scuba divers advised not to dive deeper than 40 meters?

• Compressed gases become dangerous

• The water is too cold

• There are too many marine animals

• Visibility is too low

What is the purpose of using trimix gases in deepwater diving?

• To reduce oxygen and nitrogen toxicity

• To improve visibility

• To increase buoyancy

• To attract marine life

What is a unique feature of atmospheric diving suits?

• They require SCUBA certification

• They allow for deep dives without pressure dangers

• They are lightweight

• They are used only in shallow waters

What was the significance of the Trieste's journey in 1960?

• It mapped the ocean floor

• It discovered new marine species

• It reached the deepest spot on Earth

• It was the first manned submarine

What material is primarily used in the construction of deep submergence vehicles (DSVs)?

• Aluminum

• Titanium

• Carbon Fiber

• Syntactic Foam

How do remotely operated vehicles (ROVs) differ from manned submersibles?

• They can dive deeper

• They are operated from the surface

• They have more storage space

• They are faster
