Library founded at Alexandria 300 B.C.E *The Royal Library of Alexandria was once the largest library in the world. *It was a major library and cultural center located on the shore of the Mediterranean Sea in the Egyptian city of Alexandria.
Latitude & Longitude *Latitude lines never intersect but they run East and West. Zero degrees parallel is the Equator. The equator measures distances only by Degrees. Longitude line run North & South. Zero degrees meridian is also know as The Line Of Longitude. The Prime Meridian measures distance using Degrees.
The Ancient Polynesians By Michael Abraham Ancient uses & Explorations 2000 and 500 B.C.
Culture and Location The Polynesian culture was a seafaring culture focused on oceanic exploration The Polynesians originally traveled by canoe around the islands of New Guinea Due to grater distance between Islands as exploration increased they developed double hauled vessels, capable of hauling colonists and supplies. With this new technology in transportation they then had to advance their navigation techniques, which led to a highly sophisticated system based on the stars, ocean swells, birds flight patterns and natural landmarks.
Exploration With new technology and navigation, the Polynesians went to explore on from new Guinea onto new lands in the North, East, South and West. From New Guinea the Polynesians reached islands such as Fiji, the northern Hawaiian Islands, Easter Island, and New Zeland. The reaches of Polynesian exploration and expansion is now known as and area called the Polynesian Triangle.

Ancient Greek Explorations and Discoveries
It was primarily the ancient Greeks who first used mathematical principles and sophisticated maps for seafaring. By applying their advancements in early science and mathematics, this culture contributed to understanding the oceans in many ways. Although western civilization would lose the knowledge during the Middle Ages, the Greeks knew that the world was a sphere and not flat.
The Greek Pytheas noted that he could predict the tides in the Atlantic based on the phases of the moon. About 150 years later, Eratosthenes (264-194 B.C.) calculated the Earth s circumference and invented the first lattitude/longitude system a system of imaginary lines on the Earth, used for navigation and mapping. Hipparchus invented a better system the one used today later.

Chinese Exploration and discoveries Daniel Probst
By AD 10150, Chinese navigators were using the float compass. In 1070, the Chinese developed dry docks for their ships. In the 13 th century Chinese ships ventured to India and occasionally to East Africa. Artifacts found on the Pacific Shores of America suggest the Chinese reached America before Columbus died. Chinese invented the magnetic compass around 1125 AD Chinese seafaring well established by about 1000 AD By the mid 1400 s they were well established ship builders
Prince henry the navigator By Devon Elkhay
... This is the area that Prince henry traveled from Africa. This started the Slave Trade after a few Years. Prince henry the navigator is the son of the Portugal king. He was the third surviving son of King John I and Philippa of Lancaster. Henry is often credited with beginning the Age of Discovery, the period during which European nations expanded their reach to Africa, Asia and the Americas. Henry himself was neither a sailor nor a navigator, his name just being a title.
Prince Henry Henry died in 1460 in Sagres, Portugal. By the time of his death, Portuguese explorers and traders had advanced as far as the region of modern-day Sierra Leone. It would be another 28 years before Vasco de Gama, under the Portuguese flag, would sail clear around Africa and complete an expedition to India.
Christopher Columbus by:jett Lathrop
Christopher Columbus, a master mariner is most known for discovering the New World. The Vikings had actually discovered the Americas 500 years earlier. Columbus purpose was to find a new trading route to India, hence him naming the natives Indians. Columbus had assumed that the Earth was only HALF of it s actual size. He even died beliving that he had discovered islands off the coast of Asia, not realizing the massive impact he had.

Military Applications to Ocean Exploration There are a lot of things that have to do with the ocean exploration that help the military, such as UWSNs (underwater sensor networks) By 1900 the industrial revolution had helped to expand oceanography as a science with the invention of the steam engine and iron ships. War has been a major contributing factor in the oceanography explosion.
Steam Engines and Iron Ships Steam engines and iron ships were part of the first inventions that helped the military. Steam engines are machines that perform tasks mechanically by using steam as fuel. These helped the military because they could transport things from one place to another. (Steam engines look and act like trains.) Iron ships also tremendously helped the military. Iron ships are just what they sound like. They are large ships made of iron. These also helped the military transport things from one place to another.
UWSNs UWSN = underwater sensor networks UWSNs are just one example of how ocean explorations have aided the military. UWSNs are used to enable applications for oceanographic data collection, pollution monitoring, disaster prevention, etc.

The Trip
The Challenger Ship
Summary The challenger 2 was a ship that was built to explore sea and islands going through rough conditions like water pressure and lack of oxygen but was the first to attempt exploring the vast body of water and manage to discover 4,000 unknown species but eventually it come to a end in 1876
Ocean Drilling Rachel Broadbent P3
The Ocean Drilling Program(ODP) The ODP was an international and group mission to disclose and study the structure, matter composition on the Earth s ocean fundamental basis. Drilling discoveries have led to further hypotheses and questions in Earth sciences.
Important impacts Animals such as birds and sea turtles have a destroyed habitat from the construction of new oil pipes. Contaminated sediments are pushed by the current into fish populations, which reduced the population as a whole.
Pros It s important we have ocean drilling because oil is one of the most fundamental needs in the world today. Its needed for plastic and fuel.

Oceanographic Institutions By: Sarah Shack Period 3
Albert s Institut Océanographique The first institution was founded by Prince Albert I of Monaco who gave his countries oceanographic laboratory and museum in 1906 Most famous alumnus of the Institute was Jacques Cousteau In addition Monaco became the place of the International Hydrographic Bureau, founded in 1921 The bureau published one of the first general charts of the ocean showing bottom contours
3 Preeminent Oceanographic Institutions Woods Hole Oceanographic Institution: located on Cape Cod founded in 1921 (affiliated with the Massachusetts Institute of Technology and the neighboring Marine Biological Laboratory, founded in 1888) The Scripps Institution of Oceanography: located in La Jolla, California founded in 1903 (affiliated with the University of California in 1912 The Lamont-Doherty Earth Observatory of Columbia University: located in Palisades, New York founded in 1949
NOAA The National Oceanic and Atmospheric Administration Found in the department of commerce in 1970 Includes the National Ocean Service, National Weather Service, National Marine Fisheries Service, The Office of Sea Grant Trying to facilitate commercial uses of the ocean
Submersibles Submersibles are tiny mobile research vessels that are designed for exploration of the oceans depths. They can be manned or unmanned. During the late 1950s and 1960s a great variety were developed, but the first submersible was launched in the1930s. They were needed to make direct observations and measurements, recover lost equipment, and for possible rescue activity.
Bathysphere: 1 st Type Of Submersible A Bathysphere is a manned spherical chamber for deep sea observation, lowered and raised by a cable from a ship. It cannot operate in great ocean depths and cannot move from side to side. The first one was launched in 1930.
Bathyscaphe: 2 nd Type Of Submersible A Bathyscaphe was designed in the 1940s, after the Bathysphere. It s different from the Bathysphere because it s not connected by a cable to the ship. It has water chambers to make the craft sink, and gasoline chambers to make the craft float. To get to the surface after exploration, the Pilot drops iron pellets stored in the bottom of the craft. Once launched, it is self propelled.
The Deep Sea Challenger: Latest technology In 2012, scientists used The Deep Sea Challenger for exploring the deepest parts of the ocean including the Mariana Trench(more than 35,000 feet below the ocean s surface). The Challenger is made up of a light but sturdy foam that is a substitute for steel. Gasoline tanks are not needed because the foam floats. This design allows the Pilot to spend more time on the bottom of the ocean because it descends and ascends faster than the Bathyscaphes.
Summary Because of Submersibles, people have been able to explore the ocean floor. By inventing new types of technology over the years, people can explore sealife longer and faster than the previous technology.
Self-contained diving History & scientific purpose of SCUBA diving.
Origin of scuba diving Also known as SCUBA (Self-Contained Underwater Breathing Apparatus), Scuba devices are used to explore the deep ocean floor, without the use of higher & more expensive technology, such as submarines. The earliest self-contained apparatus dates back to about 375 AD, with heavy innovations being brought upon nearly 300 years ago. Augustus Siebe introduced the hard hat diving equipment in 1840, while Henry Fleuss introduced the 1 st workable SCUBA in 1878. The Aqua-Lung, one of the earliest versions of SCUBA, was first to reach popularity & commercial success.
Pros & cons of scuba diving Positive Factors Include: - Minimalistic equipment allows for easier traversing on land & in water. - Able to operate with little to no crew with you. - Divers have a large amount of freedom to move around underwater. Negative Factors Include: - Limited dive time due to limited oxygen. - Lack of communication between divers & other divers/authorities on boat. - Limited depth travel when compared to submarines & other aquatic machinery. http://marinebio.org/oceans/scuba/ http://oceanexplorer.noaa.gov/technology/diving/scuba/scuba.html http://www.ancient-origins.net/ancient-places/ten-incredible-underwater-discoveries-have-captured-our-imagination-001522 http://umaine.edu/scientificdiving/files/2012/09/witmanet13-scuba-science1.pdf
Purpose of self-contained diving Not only is self-contained diving used for scientific purposes, but also for military work, sporting, industrial use, & commercially learning. Many scientific discoveries & advancements have occurred due to the hundreds of years of scuba diving, due to the quick progression of the technology & equipment. Such as an incredible ship wreck discovery that ages back 3,200 years ago in Croatia, & elongated skulls found in a Mayan underwater cave that scientists still have no answer to.
Robot Devices Remotely operated vehicles
Long Range Navigation (LORAN) Invented and first used in World War II Newest version is the LORAN-C, invented in 1970s Measured distance by time (in microseconds) signals took to transfer between devices Master LORAN systems would serve as a constant in one location, while secondary, or slave systems would send signals of their locations to the master system. Phased out by U.S. and Canada in 2010 in favor of Satellite-based GPS systems.
Global Positioning System (GPS) Rather than receiving signals from other transmitters, GPS uses satellites, ground stations, and receivers to transmit information. Satellites always stay in one position around the Earth, so we always know where they are Ground stations keep track and locate satellites. Receivers would read satellite signals and measures distance between itself and the satellite GPS replaced LORAN because it was a more precise method of location, with high-tech GPS systems being able to find a signal from within a fraction of an inch, as well as being able to see more of the planet with less systems tracking it.
Marine Archaeology Grant Roberts
What is Marine Archaeology? In plain terms it is the study and human interaction with any body of water. Marine Archaeology helps study the history of the ocean and aids in our understanding of it s beginning
Nautical Archaeology Probably the most relevant type of marine archaeology. Nautical Archaeology studies the remains of underwater shipwrecks. It studies the age of ships and the reason for sinking. Also involves the construction of the ship.
What does an archaeologist look like? Most, if not all marine archaeologists are veteran scuba divers.
