What is Marine Biology? The study of the organisms that live in the sea. The study of the organisms that live in the sea.

Why should we study Marine Biology? Food, medicine, raw materials and support tourism all over the world. Food, medicine, raw materials and support tourism all over the world. Marine organisms can erode sea walls, ship bottoms and clog pipes. Marine organisms can erode sea walls, ship bottoms and clog pipes. Studying marine organisms can teach us a lot about life on earth. Studying marine organisms can teach us a lot about life on earth. –Example: in the nineteenth century a scientist discovered cells of the animal immune system in sea anemones and the larvae of sea stars.

History of Marine Biology Stone Age Stone Age –Food, jewelry and knowledge of marine organisms –Example: The tomb of an Egyptian pharaoh bears a warning against eating poisonous pufferfishes Explorers Explorers –Leif Eriksson, Christopher Columbus, James Cook (chronometer), Charles Darwin, Charles Wilkes (Wilkes’s expedition), ect…..

History of Marine Biology The Challenger Expedition The Challenger Expedition –Edward Forbes-carried out extensive dredging of the sea floor. Discovered many unknown organisms and learned that sea-floor life varies at different depths. Discovered many unknown organisms and learned that sea-floor life varies at different depths. –The Challenger Expedition brought back more information about the ocean than any study previously done.

The Growth of Marine Labs Development of Technology Development of Technology –Sonar sound navigation ranging sound navigation ranging Used for submarine welfare (WWII) Used for submarine welfare (WWII) Detection of underwater echoes-listening to the sea.
