Origins & Early Life

Ocean exploration, part of oceanography, is the exploration of ocean surfaces. Notable explorations were undertaken by the Greeks, the Phoenicians, the Romans, the Polynesians, Phytheas, the Vikings, Arabs and the Portuguese. Scientific investigations began with early scientists such as James Cook, Charles Darwin, and Edmund Halley. Ocean exploration itself coincided with the developments in shipbuilding, diving, navigation, depth, measurement, exploration, and cartography. 4500 BC Around this time, humans began diving into the sea as a source of food gathering, commerce, and possibly even warfare.

Career & Major Achievements

4000 BC Egyptians developed sailing vessels, which were probably used only in the eastern Mediterranean near the mouth of the Nile River. 4000 BC - 1000 AD Polynesian colonization of South Pacific Islands. 1800 BC Basic measuring of the depths is done in Egypt. 1500 BC Middle Eastern people explored the Indian Ocean 600 BC Phoenicians developed sea routes around the entire Mediterranean and into the Red Sea and the Indian Ocean. Going around Africa they reached England by sailing along the western European coast.

Enduring Legacy & Impact

Although they understood celestial navigation, they probably stayed within sight of land whenever possible. 500-200 BC Greeks developed trade routes in the Mediterranean using the length of the day (corrected for the time of the year) to estimate latitude. 450 BC Herodotus produces a map of the Mediterranean region. 325 BC Pytheas, a Greek astronomer and geographer, sailed north out of the Mediterranean, reaching England and possibly even Iceland and Norway. He also developed the use of sightings on the North Star to determine latitude.

Historical Fact-Check Quiz: Ocean exploration

True or False: “The Phoenicians were the first civilization to develop reliable methods for determining longitude at sea.”

Answer (FALSE ❌): While they understood celestial navigation, the text notes they probably stayed within sight of land whenever possible; latitude determination was more advanced later.
