The first true ocean-going boats were invented by the Austronesian peoples, using technologies like multihulls, outriggers, crab claw sails, and tanja sails. This enabled the rapid spread of Austronesians into the islands of both the Indian and the Pacific Oceans , known as the Austronesian expansion .
Rheic Ocean, the Paleozoic ocean between Gondwana and Laurussia; Slide Mountain Ocean, the Mesozoic ocean between the ancient Intermontane Islands (that is, Wrangellia) and North America; South Anuyi Ocean, Mesozoic ocean related to the formation of the Arctic Ocean; Tethys Ocean, the ocean between the ancient continents of Gondwana and Laurasia
Ocean exploration is a part of oceanography describing 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.
The opening of the North Atlantic Ocean is a geological event that has occurred over millions of years, during which the supercontinent Pangea broke up. As modern-day Europe ( Eurasian Plate ) and North America ( North American Plate ) separated during the final breakup of Pangea in the early Cenozoic Era, [ 1 ] they formed the North Atlantic ...
The Wilson cycle theory is based upon the idea of an ongoing cycle of ocean closure, continental collision, and a formation of new ocean on the former suture zone.The Wilson Cycle can be described in six phases of tectonic plate motion: the separation of a continent (continental rift), formation of a young ocean at the seafloor, formation of ocean basins during continental drift, initiation of ...
The clockwise motion of Laurasia led much later to the closing of the Tethys Ocean and the widening of the "Sinus Borealis", which later became the Arctic Ocean. Meanwhile, on the other side of Africa and along the adjacent margins of east Africa, Antarctica and Madagascar , rifts formed that led to the formation of the southwestern Indian ...
The first long-distance ocean crossing in human history and the first humans to reach Remote Oceania. [ 5 ] [ 9 ] Austronesians in Island Southeast Asia establish the Austronesian maritime trade network with Southern India and Sri Lanka , resulting in an exchange of material culture , including boat and sailing technologies and crops like ...
Magellan discovers the Strait of Magellan and encounters a sea he names the Peaceful Sea (Pacific Ocean). Magellan becomes the first explorer to cross the Pacific Ocean, which proves far vaster than he imagined and requires an arduous four-month voyage. 1521 Ferdinand Magellan reaches Guam and the Philippines.
