One body of water covers the planet. It is divided in how many oceans, based on ocean basins.

• Three
• Four
• Five
• Six

All of the following were Early Explorers of the Oceans, with the exception of:

• Christopher Columbus
• Charles Darwin

• Ferdinand Magellan
• Albert Einstein

Sir Charles Thompson is attributed with:

• The Challenger Report

• Providing 4700+ new specimens for study

• Set new standards for ocean study

• Laying the foundation of modern Marine Science

• All of these

Challenges of studying the ocean are:

• Distance from shore and lack of light in deeper waters

• Lack of air

• Colder temperatures

• Sharks and jellyfish

• Higher pressure in deep waters

The first Marine Laboratories allowed:

• The general public a place to tour and visit marine animals.

• Scientists room and opportunity to study living organisms.

• Eat some of the finest seafood in the area.

• People to swim with dolphins.

SONAR stands for:

• Sound Navigation And Ranging
• Sound Navigation And Reacting
• Sound Navigation And Reaching
• Sound Navigation And Reading

The acronym SCUBA stands for:

• Self-Contained Underwater Breathing Apparatus
• Submarine Controlled Underwater Breathing Apparatus
• Self-Controlled Underwater Breathing Apparatus
• Submersible Controlled Underwater Breathing Apparatus

The average depth of the ocean is:

• 1000 meters
• 2000 meters
• 3000 meters
• 4000 meters

Two major developments in types of submersibles are:

• Bathysphere & Bathyscaphe

• Peanut Butter and Jelly

• Military and Satellite operations

Unoccupied, highly maneuverable underwater machines that can be used to explore ocean depths while being operated by someone at the water surface.

• Remotely Operated Vehicles (ROVs)
• Submarines
• Scuba Diving Equipment
• Underwater Drones
