7. Why are you here? What is Marine Biology?

8. Marine Biology Study of organisms that live in the ocean Subset of Biology Many subdisciplines

9. Marine Biology Why is it important?

10. Marine Biology Why is it important? –Food, medicine, raw materials, recreation –Disease, attacks, damage –Effect the global ecosystem –Recreation, education –$$$$$$ ($20 trillion/yr!) –71% of the earths surface is WATER!

11. Marine Biology It is a science, “a general science of biology, but applied to the sea.” –There is a reason why things happen –Discover these reasons by systematic methods

12. History of Marine Biology Ocean explored for food, as trade routes, wars, etc. Aristotle (4 th century BC) – first marine biologists

13. History of Marine Biology Many voyages of exploration Captain James Cook (European, 1700’s) –First to include a fulltime naturalist

14. History of Marine Biology Charles Darwin –Naturalist on HMS Beagle (1831) –Atolls, plankton, barnacles

16. History of Marine Biology Edward Forbes –Dredges the Ocean floor (1840’s & 1850’s) –Azoic Theory – no life below 2000 ft. (pg. 359 text)

17. History of Marine Biology First Voyages ever to specifically study the ocean (19 yrs. to publish, 50 volumes) Challenger Expedition (1872-1876): measuring systems used, species samples

19. The Ocean Ocean Facts: Covers 71% of the earth’s surface Accounts for 97% of the water on earth (rest in land ice, groundwater, lakes & rivers) Average depth = 3,796 meters (12,451 feet) (deepest = Mariana trench 11,022 m or 36,163 ft) Average temp = 3.9 o C (only 39 o F)
