Skilled sailors are able to navigate using the stars, sun, ocean conditions (wind, waves), and other natural cues (such as seabirds and clouds).
Painting by Herb Kawainui Kane
Oceanographers navigate the ocean using a variety of technological tools such as radar, sonar, and satellite communication.
The Hypothesis . . .
From many years of boat observations, scientists knew that Hawaiian albatross visited the west coast of North America.
Reminds us of a few critical aspects about science:
• Scientific knowledge is subject to change.
• Technology and human creativity aid science.
• Hypotheses not supported by data are just as important as hypotheses that are… they both advance our understanding.
A great discovery!
• Scientists used satellite tracking to follow the birds’ movements.
• A satellite tag was attached to a few feathers with tape.
•The scientists can determine the animals’locations after they are released.
How do we know?
More details on this technology later...
Now it’s your turn
Use coordinates to track positions of individual albatross on a map of the Pacific Ocean.
A Quick Review - Latitude
• Measured in degrees north or south of the equator (line of 0 °°latitude).
• Lines of latitude run parallel to the equator.
A Quick Review - Longitude
• Measured in degrees east or west of the Prime Meridian (line of 0 °°longitude).
• Lines of longitude meet at the north and the south poles.
The Pink-footed Shearwater raises chicks on islands off Chile. One colony is on the famous Robinson Crusoe Island. How far do these birds migrate?
