Unit 1 Introduction to Oceanography

1

Used to estimate the transparency of seawater, and can provide a relative measure of productivity or turbidity

1

Unoccupied, highly maneuverable underwater robots operated by a person aboard a surface vessel

1

Samples a wide variety of ocean and fresh water sediment. Designed to take samples in ooze, Clay, sand, gravel, and pebbles on flat or gently sloping bottoms

1

A device used to measure the salinity of liquids and solutions

1

Used to analyze grain size composition

1

Measures ocean currents

1

Wire leads through an electro-magnetically metered wheel attached to a J-frame to track the
amount of wire that has been used to lower equipment into the ocean

1

SCUBA

1

A drill used to collect a long tube of sediment

1

Uses sound waves and computer imaging to get a picture of the ocean floor

1

Uses gravity and microwave radio, timing the interval between transmitting a short pulse and receiving a reflection back from the sea surface, to map the ocean floor

Alvin

1

Who built elaborate canoes to carry supplies and developed a navigation system based on the position of the stars?

1

This person noticed that ships travelling against water currents took longer to return and was the first person to map the Gulfstream

1

Developed the theory of coral reef formation and atolls (ring-shaped coral reefs) & origin of species while sailing on the HMS Beagle

1

Inventor of diving devices and scuba devices such as the Aqua-Lung

1

The ship that discovered the Mariana Trench in 1875

1

Polynesian stick charts were used to:

1

Before the 1800's, Edward Forbes stated that the abundance and variety of marine life decreased with increasing depth. This theory was known as:

1

Place a check next to each of the 5 principle oceans.

1

How and why ocean currents flow and air-sea interactions such as the generation of waves by wind, is what type of Oceanography?

1

Study of rock structure in the ocean basin, properties of rocks such as magnetism and the occurrence of earthquakes is what type of Oceanography?

1

Studying organisms that live in the ocean and their relationship to the environment is what type of Oceanography?

1

Studying the composition of sea water and the processes controlling and altering its composition, including marine pollution, is what type of Oceanography?

1

What is Oceanography?

1

What percentage of the Earth's surface is covered by oceans?

1

Oceanography can be used to predict the weather and show weather patterns.

1

The study of Oceanography is needed to maintain our food supply from fisheries.

1

The Atlantic Ocean is the largest of the 5 oceans.

1

The Challenger Deep is located near Chili in the Pacific Ocean.
