Blue whales
don’t migrate…
• Humpbacks begin migration at their birthing area north of the
Dominican Republic on the Silver Banks. They end their voyage in
the Labrador Sea, in the Gulf of St. Lawrence, or in areas off the
Canadian Maritime Provinces. Gray Whales begin their journey
near Baja California and then swim northward to the waters of
Alaska, the Bering Sea, and the Chukchi Sea (CHOOK – chee).
• The waters in southern areas are used for breeding or birthing in
winter. Northern waters are used for feeding in spring and
summer.
• From southern to north waters in spring, and the opposite in fall.
• Humpback Whales will travel approximately 4500 km (2800 miles),
while Gray whales will travel approximately 9000 km (5600 miles).

Jamur traveled from Central America, through the Atlantic, across
to Europe (off the coast of Portugal), and South to Africa. If the
distance measured is approximately 31 cm (acceptable range is 2933 cm), the distance traveled is approximately 12,200 km. Over 54
weeks, Jamur’s traveled an average of ~226 km per week.
Where they go so humans can protect them.
In what climates and marine ecosystems they can be found.

Sample of satellite imagery
demonstrates that 4-kilometer
resolution (km) imagery, where each
pixel in the image represents an area
of 4 km x 4 km, is more detailed than
16-kilometer resolution.
Satellite tagging of Blackfooted Albatross resulted in
the discovery that these
animals travel throughout the
North Pacific.
It was thought that Great White
Sharks in the Pacific Ocean
wandered aimlessly, never
venturing into the San Francisco
Bay. However, scientists recently
followed over 100 tagged sharks
and found that five sharks swam
under the Golden Gate Bridge and
into the San Francisco Bay on
several visits.
Elaborate:
Using the map below and the map you plotted in the EXPLORE section, con
distance and duration of the route of the Leatherback Sea Turtle with the r
traveled by Zubenelgenubi, the Black-footed Albatross.
