What is Marine Science? Marine science: the study of the ocean, its ecosystems, and life forms Interdisciplinary Marine Biology Chemical Oceanography Geological Oceanography Physical Oceanography

Marine Biology Study of life in the ocean (characteristics, physiology, life history, interactions) and the ocean’s role as their habitat

Chemical Oceanography Study of the chemical changes the ocean, sea floor, and marine organisms undergo

Geological Oceanography Study of the ocean’s topography, structure, and geological process of the ocean floor Understand how Earth & oceans were formed and how current processes may change them

Physical Oceanography Study of physical conditions, properties, and processes within the oceans, especially motion

World’s Oceans From largest to smallest by volume: • Pacific • Atlantic • Indian • Arctic • Southern

World Ocean

Importance of Oceans Ocean helps regulate temperature of Earth Absorb 90% of heat trapped by atmosphere

Importance of Oceans >70% Earth is covered by ocean 97% water on Earth is in ocean Glaciers, ice, rivers, lakes, groundwater 3%

Importance of Oceans 50 -80% oxygen we breathe from ocean Phytoplankton

Importance of Oceans Economics (trading, tourism, jobs) Recreation (fishing, diving)

Importance of Oceans 40% of world population on coast

Importance of Marine Organisms 80% of known life is in the ocean 99% living space on plant = ocean Animals = bioindicators of ocean health “Wipe out all life on land life would still exist in the ocean. Wipe out all life in the sea and nothing would be left on land. ”

How do YOU rely on the ocean?
