Lesson 2 Presentation Content Engage – Navigating the Ocean Explore – Plotting Albatross Locations Explain – Analyzing Albatross Movements Elaborate – Satellite Tracking Evaluate – Other Seabird Movements

Engage Navigating the Ocean

A crucial skill for ocean exploration is to map your location, often with no landmarks.

Painting by Herb Kawainui Kane Skilled sailors are able to navigate using the stars, sun, ocean conditions (wind, waves), and other natural cues (such as seabirds and clouds).

Oceanographers navigate the ocean using a variety of technological tools such as radar, sonar, and satellite communication.

Satellites are important in the scientific study of the oceans and marine life

Seabirds, especially albatross, spend most of their lives at sea.

Where do they go?

The Hypothesis. . . From many years of boat observations, scientists knew that Hawaiian albatross visited the west coast of North America.

The first albatross ever tracked from Hawai‘i confirmed this migration route

Do albatross from other Hawaiian Atolls travel to the same places?

A great discovery! 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.

How do we know? • 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. More details on this technology later. . .

Explore Plotting Albatross Locations

Now it’s your turn Use coordinates to track positions of individual albatross on a map of the Pacific Ocean.

Plot Albatross Routes from 3 Tagging Sites

Tagging Site: Kure Atoll Seabird Sanctuary

Tagging Site: Tern Island, National Wildlife Refuge

Tagging Site: Waters over Cordell Bank

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 nests in Chile and migrates to ?

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?
