History

When do you think people first started learning about

marine life?

• From the moment they saw the ocean.

History

Archeologists have discovered piles of shells, the remains

of ancient “clambakes”

They have also discovered harpoons & simple hooks of

bone & shell dating back to 5000 B.C.

Through experience people learned

Which food was good & which were bad.

History

Phoenicians:

• First to accomplish Western

navigation

• 2000 B.C. they were sailing the

Mediterranean Sea, Red Sea,

eastern Atlantic Ocean, &

Indian Ocean.

• 1938 - 1756 B.C. they built the

canal, the Isthmus of Suez, to

navigate ships across land.

History

Greeks:

• First used mathematical principles and sophisticated maps

for seafaring.

• Eratosthenes (264-194 B.C.) mathematically calculated the

circumference of the Earth at 40,000 km (actual 40,032 km).

• Aristotle (4th Century B.C.) considered by many to be the

first marine biologist (describe marine life).

• Pytheas (Geographer) noted that he could predict the tides in

the Atlantic based on the phases of the moon.

History

Vikings:

• Crossed the North Atlantic to

colonize Iceland, Greenland, &

Newfoundland in 900 A.D.

• Leif Eriksson (995 A.D.) discovered

Vinland, now called North America.

History

Arabs:

• Traders actively voyaged to eastern Africa, southeastern

Asia, & India during the middle ages (1000 A.D.).

• Learned about wind and current

patterns, including strong winds

that reverse direction with the

seasons.

• They are believed to have

invented the lateen sail

(triangular sail). http://exhibitions.nypl.org/africansindianocean/essay-arabian-peninsula.php

History

Chinese:

• Responsible for inventing the magnetic compass.

• Developed central rudders & watertight compartments.

More History

Individuals:

1492 A.D. - Christopher Columbus rediscovered New World.

1519 A.D. - Ferdinand Magellan

• Circumnavigated globe (accurate maps!)

• He actually died before the journey was

finished, but his crew returned in 1522.

More History

1728 A.D. - John Harrison

• Developed the first chronometer (spring run timepiece

allowing longitude to be known)..

1762 A.D. - Benjamin Franklin (American)

• Created chart of the Gulf Stream.

• The Gulf Stream gives the eastern

U.S. its warm climate, bringing

warm water north from the equator.

1786 A.D. - James Cook (British Royal Navy)

• Made numerous scientific observations.

• Considered the first marine scientist.

More History (cont.)

1831 A.D. - Charles Darwin

• Known for “natural selection,”

• Also described how atolls are formed!

1838 A.D. - Charles Wilkes

• charted 1500 miles of coastline & collected

10,000 specimens (2000 new).

• First effort sponsored by U. S. government!

1840 A.D. - Mathew Maury (U.S. Navy)

• Father of Oceanography, published “The Physical Geography

of the Sea.”

• Through sounding discovered the Mid-Atlantic Ridge.

More History (cont.)

1840 A.D. - Edward Forbes

• Sea floor dredging (discovered new organisms).

• Led the way for the Challenger expedition.

HMS Challenger

1872-1876 Charles Wyville Thomson & John Murray

• HMS Challenger expedition.

• First pure oceanographic investigation that

stimulated the science of marine biology.

• Expedition lasted 1,000 days and covered

more than 68,000 nautical miles.

• Discovered 4,727 new species, tested water, made

soundings, 151 trawls, currents, meteorology, sediments, &

charted reefs.

• Compiled a 50 volume set of information still used today.

• Discovered the world’s deepest ocean trench, the Marianas

Trench, sometimes called the Challenger Deep.

Challenger Map

Research Vessels

1895 - Fridtjof Nansen

• Studied the polar oceans aboard the

Fram (ship built to withstand crushing

ice).

1898 - John Holland

• Invented the 1st gas engine/battery

powered submarine.

Research Vessels

1925 - German Meteor Expedition

• Use of echo sounding (depth and contour) discovered the

ocean floor was rugged, not flat as previously thought.

• South Atlantic to the Antarctic.

1943 - Jacque Cousteau & Emil Gagnan

• Invented the “aqualung.”

http://otlibrary.com/invention-of-the-aqua-lung/

Research Vessels

1960 - Jacque Piccard & Don Walsch

• U.S. Trieste bathyscaphe (small submarine).

• Descended 35,801 ft. into the deepest

part of the ocean, the Marianas trench.

• NO ONE HAS BEEN BACK SINCE!

Research Vessels

1962 - The Alvin

• Designed by Woods Hole Oceanographic Institute

• First deep sea submersible with mechanical arms

• In 1966 helped to locate an H-bomb that was lost in the

Mediterranean Sea.

• In 1979 discovered black smokers on the sea floor.

Research Vessels

1968 - The Glomar Challenger

• Confirmed evidence of seafloor spreading & plate tectonics

from core drilling samples.

Research Vessels

1989 - Japan launched the Shinkai 6500

• Carried a crew without a tether (rope) up to 21,414 ft deep

into the ocean (a world record).

2006 - Chinese mineral company (COMRA) designed a craft to

reach 23,000 ft.

Marine Labs

Before the Challenger set off; biologists were excited about the

organisms brought back; however, …

• There was only a limited amount of room on oceanographic

vessels.

• Living specimens were essential to the study of biology, but

ships stayed in one place for short periods of time.

Where else were marine biologists able to study marine

organisms?

• Seashores

Marine Labs

Biologists began conducting studies along the seashore.

• Among the first of these were Frenchmen, Henri Milne

Edwards & Victor Andouin (1862).

Seashore excursions allowed for the study of live organisms, &

so permanent laboratory dedicated to marine life were

established.

Marine Labs

1872 - The first marine laboratory was the Stazione Zoological.

• Founded in Naples, Italy.

• The same year the HMS Challenger embarked.

1879 - The laboratory of the Marine Biological Society of the

United Kingdom.

• Founded at Plymouth, England.

1888 - Marine Biological Laboratory at Woods Hole.

• At Woods Hole, MA

• The first major American marine laboratory.

Marine Labs

After these early beginnings, other marine laboratories were

established.

Among the earliest in the U.S. were:

• Hopkins Marine Station in Pacific Grove, CA.

• Scripps Institute of Oceanography in La Jolla, CA.

• Friday Harbor Marine Laboratories in Friday Harbor, WA.

Many marine laboratories appeared around the world & were

vital to the growth of marine biology.

Marine Technology

What type of human endeavor leads to technological

advancement?

• War

The onset of World War II had a major effect on the

development of marine biology. Why?

• Sonar or sound navigation ranging was developed in

response to submarine warfare.

• Marine animals use this same technique & marine biology

became a matter of national security.

Marine Technology

The years immediately after WWII saw refinement of the first

really practical SCUBA (Self Contained Underwater Breathing

Apparatus).

• Jacques Cousteau & Emil Gagnan modified the apparatus to

breathe compressed air underwater.

• For the first time marine biologists were able to descend

below the surface of the water to observe marine organisms

in their natural environment.
