What is Oceanography (Marine Science) - CORRECT ANSWER✅✅✅The scientific study of the ocean
in all its aspects
Aims of Oceanography - CORRECT ANSWER✅✅✅To define, describe, understabd, predict, and
utilize the oceans for basic research and applied uses
Shape of the earth - CORRECT ANSWER✅✅✅not a perfect sphere, its oval
Latitude - CORRECT ANSWER✅✅✅Horizontal lines. The angular distance, in degrees, minutes, and
seconds of a point north or south of the equator. Line of latitude are often referred to as parallels. Used
to find distance)
Longitude - CORRECT ANSWER✅✅✅Shown as vertical lines. Is the angular distance, in degrees,
minutes, and seconds, of a point eat or west of the prime meridiacn (Greenwich, England). Lines of
longitude are often referred to as meridians.
Important Parallels - CORRECT ANSWER✅✅✅66.5 N - Arctic Circle
66.5 S - Antarctic Circle
23.5 N Tropic of Cancer
23.5 S Tropic of Capercorn
Degrees of Latitude - CORRECT ANSWER✅✅✅There are 180 degrees laitude, 90 N and 90 S
Degrees of Longitude - CORRECT ANSWER✅✅✅There are 360 degrees of longitude, 180 E and 180
W
Prime Meridian - CORRECT ANSWER✅✅✅0 degrees longitude. Passes through Greenwich, England
,How to find Latitude - CORRECT ANSWER✅✅✅Stars - Starts remain fixed in the horizon throughout
the year, rotating around a common point
The North Star
Sextant - CORRECT ANSWER✅✅✅Used to measure the angle of Polaris above the horizon to get
latitude
Longitude and time - CORRECT ANSWER✅✅✅The clock is set at noonwne the sun is at its highest
above the prime meridian. every 15 degrees of longitude is equal to 1 our
John Harrison - CORRECT ANSWER✅✅✅developed the first accurate sea going clock in response to
large cash prize by british government
GPS - CORRECT ANSWER✅✅✅Global Posting System
Controled by the US Department of Defense. designed to help US military
GPS senses 4 satellites, then uses them to tell you your location.
Polaris - CORRECT ANSWER✅✅✅North Star
Sits above the spin axis, angle of you from polaris is where you are. Want to go east or west, you keep
angle between polaris constant. want to go north, grow angle. want to go south, shrink angle
Who started oceanography - CORRECT ANSWER✅✅✅eqyptians developed the arts of shipbuilding
and ocean piloting
Herodotus - CORRECT ANSWER✅✅✅compiled a map of the known world
First diver - CORRECT ANSWER✅✅✅Aristotle. He down in a glass ball. Alexander the Great did it too
Exploration of Polynesians - CORRECT ANSWER✅✅✅Set out on big canoes with sails to all pacific
islands and settled there.
Used stick map to tell them where islands were
, Pytheas - CORRECT ANSWER✅✅✅explored the coasts of england, norway, island... developed a way
to determine latitude. also proposed a conection between phases of the moon and the tides
Meteorologica - CORRECT ANSWER✅✅✅Aristotle published it, describing geography and physical
structires of the known world
Historia Animalia - CORRECT ANSWER✅✅✅Aristotle published first book on marine biology
Eratosthenes - CORRECT ANSWER✅✅✅made a ner map of the world and determined the
circumference of the earth
Seneca - CORRECT ANSWER✅✅✅devised hydrologic cycle, showing that, despite inflow of river
eater, the ocean level remained stabled because of evaporation
Ptolemy - CORRECT ANSWER✅✅✅compiled a map of the entire Roman world that showsed
latitudes and longitudes. He "Improved" on eratosthenes estimates of the earth circumference, but had
the earth only at 70%of its true size
Venerable Bede - CORRECT ANSWER✅✅✅published on the lunar control of tides, tidal variation,
and the effects of wind on tidal height
Vikings - CORRECT ANSWER✅✅✅primarily raiders in wooden boats, reached Iceland and Greenland.
Eric the Red - CORRECT ANSWER✅✅✅completed first trans-atlantic crossing and visited canadian
arctic
Leif Erikson - CORRECT ANSWER✅✅✅established North American settlement of vinlan in
nerfoundland
Columbus - CORRECT ANSWER✅✅✅first european to reachthe Caribbean (used Ptolemy's incorrect
estimate of the earths circumference to convince the spanish court to support his voyage
