The Science of Marine Biology

These flashcards cover key concepts, definitions, and historical context within the study of marine biology.

What is marine biology?

The scientific study of life in the sea.

Why are many students attracted to marine biology courses?

Because of the beauty, mystery, and variety of sea life.

What is a major practical reason to study marine biology?

It teaches us about the origin of life on Earth, which probably originated in the sea.

What do marine organisms provide that is significant to humans?

Food, medicines, raw materials, and recreation.

How do marine organisms contribute to Earth's oxygen supply?

They produce around half of the oxygen we breathe.

To what science is marine biology closely related?

Oceanography.

What branch of oceanography is most closely related to marine biology?

Biological oceanography.

What was the key outcome of the Challenger Expedition?

It laid the foundations of modern marine science and revealed the enormous variety of marine life.

Who is often considered the first marine biologist?

Aristotle.

What significant advancements were made in marine biology after World War II?

The development of sonar and scuba technology.

What was the Census of Marine Life (COML)?

A 10-year initiative launched in 2000 to study marine biodiversity and document undiscovered species.

How did the use of satellites enhance marine biology?

They provided large-scale observations of ocean currents and marine life distribution.

What is the scientific method?

A set of procedures used by scientists to learn about the world.

What is a hypothesis?

A statement that might be true and is testable.

Why can't hypotheses be proven true?

Scientific hypotheses cannot be absolutely proved; they can only be supported by evidence.

What is a scientific theory?

A well-tested hypothesis that is accepted as true until contradicted by new evidence.

How do marine biologists conduct experiments?

By manipulating nature to test hypotheses and control variables.

What is the significance of controlled experiments?

They allow scientists to isolate specific variables to determine their effects.

Who were John Steinbeck and Ed Ricketts?

John Steinbeck was a writer who contributed to marine biology largely due to his friendship with marine biologist Ed Ricketts.

What is the role of technology in marine biology today?

Technology enhances observation, data collection, and overall understanding of marine ecosystems.
