Tides
Starting from around 673 until 735 A.D.
The connection between the moon and Earths' tides was made by an English historian. He is often referenced as "the Venerable Bede," he figured out the phases of the moons matched with phases of tides. He was the first to find this connection. -

Prince Henry
Prince Henry the Navigator funded many expeditions that would travel the world by ship. He then founded a school for learning the study and components of navigation. -
Aug 3, 1441
Slave Trade
With learning more about the ocean came more exploitation of the ocean. New trade routes were created along with the African slave trade which began in 1441. -
Sep 9, 1519
Expedition Circumnavigates
CircumnavigateBeginning in 1519 up until 1522, Ferdinand Magellan's began his expedition to circumnavigate the globe. His goal was to reach the spicily rich islands of Indonesia but he was killed in the Philippines and his crew was the only ones to survive therefore completing the expedition. -
Mar 3, 1529
Portuguese Cartographer
A Portuguese cartographer created the first map to show the Pacific Ocean with India and China correctly placed and marked on the map. This map also marked the North and South Pole. Previous maps were very skewed but this one had the oceans and landmasses correctly placed. -
Barometer
A man by the name of Torricelli, nationality from Italy invents the barometer. This new instrument could track when storms were near a ship or on their way. -
First Marine Chronometer
Harrison, who was a British inventor, invented a clock with a "spring" inside of it instead of a pendulum like all the other clocks of the time. This was the first marine chronometer, gave the time on a ship at sea. At that time in history clocks contained a pendellum which wouldnt work out in sea bcause of the constant moving of the waves. -
Gulf Stream
Travelling from North America to England constantly allowed Benjamin Franklin to note an important detail about our ocean. A current made ships go faster traveling to England because this "stream" was located along the east coast only. But coming back to North America, the ship would have a harder and lonoger time. He called this the Gulf Stream. -
SteamShip
A man by the name of Perier from France was an inventor. He was the first to invent the steamship. This ship used the water to power its engines and move through the water. This was another option for travelers and was convenient since there was plenty of water. -
Mapping Ocean Currents
Ocean currents began to be mapped in 1847 by a man named Maury. From his observations and research he created multiple charts and published them under the name of "Wind and Current Charts." -
Return to England
The Challenger was a boat with dozens of instruments on it to study the ocean. This vessal made various trips around the world to places like Hawaii, Africa, South American countries. Also, trips throughout the Atlantic and Pacific Ocean. After all these trips, the Challenger took its last voyage to England in May of 1876. -
Fridtjof Nansen
Fridtjof Nansen, a Norwegian scientist who was the first to do research about the Arctic. He collected critical data about the world oceans, magnetic field, and climate. He used Arctic currents to help his studies. -
The Fram
Fridtjof Nansen takes a ship to the Arctic to study but also to prove his idea that the Arctic has no land. He believed that the Arctic was only ice and nothing else. He used a ship called "the fram" to help him in his studies. -
Ocean Drilling
A program was created by international groups of oceanographers part of an instituation and the U.S. National Science Foundation to test Tuzo Wilsons hypothesis. They performed ocean drillings to test the hypothesis of plate tectonics. Ocean drilling would then be used to exploit the oceans natural resources, the main one being oil. -
Gulf of Mexico
Oil dirllings began in the Gulf of Mexico. Natural resources began to be extracted from the bottom of the ocean. One of the big and most profitable natural resources was oil.When oil wells would be damage, hundreds of gallons of oil would be released into the water causeing damage to the ocean. Hundred of fish and other sea creatures were killed during these eventa, disrupting the natural form of things. (exploiting our oceans) -
Deepwater Horizon Oil Spill 2010
One of the worst oil spills in history was of the oil-drilling rig from the Deepwater Horizon that exploded and then sank. Drilling oil from the ocean goes miles deep and after this rig sank, the well was not sealed therefore millions of gallons of oil continued to be release for ~three months.
