Prince Henry The Navigator
New World explorer - 3rd son of royal family of portugal. He is most famous for the voyages of discovery that he organised and financed, which eventually led to the rounding of Africa and the establishment of sea routes to the Indies. Prince Henry established a school for the study of the arts of navigation, mapmaking, and shipbuilding. This would allow sailors to better guide their ships and to come up with new ship designs. -

James Cook
!768-1779
He circumnavidgated areas such as New Zealand, mapped coastlines, explored the Great barrier Reef and evend studied prtions of the Southern Ocean. He contributed to oceanography by helping find many know island, such as Hawaiii, the Cook Islands, and + more -
Benjamin Franklin
Benjamin Franklin made the first scientific study of it and gave it its name. Franklin measured water temperatures during several Atlantic crossings and correctly explained the Gulf Stream's cause. Franklin and Timothy Folger printed the first map of the Gulf Stream in 1769-1770. -
Matthew Maury
devoted his time to the study of marine meteorology, navigation, and charting prevailing winds and currents. His Physical Geography of the Sea, 1855 was the first textbook of oceanography. Many nations sent oceanographic observations to Maury at the Naval Observatory, where he and his colleagues evaluated the information and gave the results worldwide distribution -
Challenger Expedition
scientific exercise that made many discoveries to lay the foundation of oceanography -
Sonar
Sonar is a technique that uses sound propagation (usually underwater, as in Submarine navigation) to navigate, communicate with or detect other vessels. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. use by humans in the water is initially recorded by Leonardo Da Vinci in 1490: a tube inserted into the water was said to be used to detect vessels by placing an ear to the tube. -
Bathysphere
William Beebe descends to a depth of 3027 feet off Bermuda in a tethered bathysphere to observe deep ocean life. Beebe invented and tested the bathysphere with his friend Otis Barton. -
Trieste
In 1960 the bathyscraphe Trieste descends to the bottom of the Mariana Trench a record depth of 35,801 feet. Used by the Navy for oceanography testing. -
Hydrothermal Vents
Hydrothermal vents discovered on the ocean floor, which helped understand more about Earth's life. For there was life around these vents. -
Satellite seast
The satellite Seast is launched and maps 5 percent of the ocean surface in 3 months before failing. Was the first satellite used to remotely map Earth's oceanography surface. -
Kaiko
The unmanned submersible Kaiko comes wintin 3 feet of the bottom of the Mariana Trench when a cable breaks. -
Pytheas
Pytheas of Massalia or Massilia (4th century BC), was a Greek geographer and explorer from the Greek colony, Massalia. He made a voyage of exploration to northwestern Europe at about 325 BC. He travelled around and visited a considerable part of Great Britain. Some of his observations may be the earliest report of Stonehenge. Pytheas is the first person on record to describe the Midnight Sun -
BC Eratosthenes
He was a Greek mathematician, elegiac poet, athlete, geographer, astronomer, and music theorist. He was the first person to use the word "geography" and invented the discipline of geography as we understand it. He invented a system of latitude and longitude. -
AD Ptolemy
Ptolemy was the author of several scientific treatises, at least three of which were of continuing importance to later Islamic and European science. The first is the astronomical treatise now known as the Almagest. The second is the Geography, which is a thorough discussion of the geographic knowledge of the Greco-Roman world.
