navigator sea

A navigator is sb. who finds the position and plots the course of a ship by using maps and nautical instruments.

Page 7: The Arctic Ocean the Indian Ocean the Pacific Ocean the Atlantic Ocean

find new places within an already identified island or continent

A explorer is sb. who travels into or through a place in order to learn about it.

Very often navigators are also explorers.

Can you identify these early navigators\explorers?

Zheng He, the most famous Chinese na

vigator, lived from 1371 to 1433 and mad

e seven voyages around the South China

Sea, visiting more than thirty countries.

The people there gave him a warm welco

me. And he not only spread Chinese cult

ure, but also developed many trade lin

ks with the other countries.

Page 12: The Arctic Ocean the Indian Ocean the Pacific Ocean the Atlantic Ocean

In the years between 1405 and 1433, s

even large treasure fleets sailed westwar

ds on voyages of trade and exploration.

Under the command of Zheng He, the fle

ets set sail from the South China Sea acr

oss the Indian Ocean to the Red Sea, and

then traveled further south, discovering t

he eastern coast of Africa.

Page 13: The Arctic Ocean the Indian Ocean the Pacific Ocean the Atlantic Ocean

He renewed relations with the

Kingdoms of the East African coast.

One African king sent the Ming

emperor a royal present: two giraffes.

Marco Polo was the only person to pro

vide information about China to the ou

tside world. His journey around Asia la

sted 24 years. He reached further than

any of his predecessors, travelling beyo

nd Mongolia and into China. Finally he

wrote his adventures down and his boo

k was published and became a best-sell

er.

Page 17: The Arctic Ocean the Indian Ocean the Pacific Ocean the Atlantic Ocean

About 700 years ago a young trader from

Italy took a long trip to Cathay. Cathay is

known as China today. He went with his father

and uncle, who had traveled there once before.

They stayed in China for about two decades.

The young man's name was Marco Polo. He

was liked by the leader in China at the time.

Page 18: The Arctic Ocean the Indian Ocean the Pacific Ocean the Atlantic Ocean

He knew four languages and traveled a

round the kingdom as the leader. When

Marco Polo returned to Italy, he dictated

his story to a writer. He told of the Chines

e postal system, paper money, and the use

of coal as fuel.

James Cook

Page 20: The Arctic Ocean the Indian Ocean the Pacific Ocean the Atlantic Ocean

James Cook (1728-1779) was the greatest Bri

tain navigator. Cook enlisted in the Royal Navy

in 1755. In 1768 he was promoted and sent to th

e Pacific where he surveyed Tahiti, New Zealan

d, and Australia. On his famous second expediti

on (1772-1775) he explored Antarctica. In 1776

he undertook his third and final voyage in whic

h he explored

Page 21: The Arctic Ocean the Indian Ocean the Pacific Ocean the Atlantic Ocean

the West Coast of North America and trie

d to locate a passage between the Atlantic

and Pacific oceans.

On this voyage he discovered the Hawai

ian Islands, and sailed up the coast of Nor

th America through the Bering Straits to t

he Arctic Ocean. On his return he was kill

ed by Hawaiian islanders.

The astrolabe measures the height and

position of the sun. If you can measure

this accurately, a sailor can tell how

many degrees the boat is from the

North Pole. From this he can tell

where the boat is in the ocean.

sextant

Page 29: The Arctic Ocean the Indian Ocean the Pacific Ocean the Atlantic Ocean

The sextant is a navigational instrumen

t for measuring the angle between the h

orizon and some object in the sky. First

a sailor looks at the horizon through an

eyepiece( 接目镜) . At the same time h

e can see light from the sun or a star ref

lected off a small mirror on top of the i

nstrument, onto a second mirror and in

to the eyepiece.

The navigator can then see two images,

the horizon and the sun side by side. He

can then measure the angle between

them on a scale at the bottom of the

instrument. The scale goes from 0 to

120 degrees. An earlier instrument,

called a quadrant, measured in angle in

the same way but it could only measure

angles from 0 to 90 degrees.

nautical chartnautical chart

Page 33: The Arctic Ocean the Indian Ocean the Pacific Ocean the Atlantic Ocean
Page 34: The Arctic Ocean the Indian Ocean the Pacific Ocean the Atlantic Ocean

Nautical charts are maps of the depth of the sea and the currents of the oceans. They provide modern sailors with routes through the seas, rather like roads through the countryside. The information began to be collected in the nineteenth century and has continued to be updated ever since. These charts were not available to Captain Bligh or Zheng He.

1. Read the passage and answer the following questions.

1) What is the use of a bearing circle, astrolabe, quadrant or sextant? ( ) What is the use of a compass? ( )

A. To set the course of the ship B. To measure the position of the ship C. To measure the speed of the ship D. To tell the time

2) Why are speed and time important in working out the longitude of a ship?Speed and time are important in finding out the longitude of a ship because the earth moves fifteen degrees westwards every hour. If you know your direction, speed and time, you can work out the approximate longitude or change in your position in relation to the stars.

3) Why is the position of the sun and various

stars useful for working out latitude?

The position of the sun and stars are

useful for working out latitude because

they are fixed points in the sky and their

movements in relation to the earth are

already known. So they can be used to

measure a ship's position.

1. What skills would you seek in your sailors?

The sailors would need to be excellent navigators, able to cope with both hot and cold weather, experienced in sailing through very bad weather and able to co-operate in a team.

Page 60: The Arctic Ocean the Indian Ocean the Pacific Ocean the Atlantic Ocean

2. What problems would you anticipate for this journey?

I would anticipate very hot weather (around the equator), cold weather (around Cape of Good Hope), very stormy seas (around the Cape), and problems with food and water, etc.

What would you do if you came across the following problems during your voyage?

What would you do if: Plan of action

You were far from land and a storm arose.

You knew your latitude but didn’t know your longitude.

You were blown off-course.

You were offshore but you needed more food and water.

You wanted to keep a straight course.

You were lost with no land in sight.

wait till the storm is over, and then find your new position and return to your original course

use knots to find your speed and work out your approximate longitude

use the compass and the astrolabe, quadrant or sextant to find out your position, return to your former course.
