The Franklin Island ( English : Franklin Iceland ) is an island in the Antarctic Ross Sea . It is approximately 12 km long and is located north of Ross Island and Beaufort Island and east of McMurdo Sound .

The island is of volcanic origin and formed in the Pliocene . Rock samples taken from the lower 100 meters of the island show an age of 3.3-3.7 million years.

James Clark Ross landed on the island on January 27, 1841 and named it after John Franklin , the governor of Van Diemens Land ( Tasmania ).

There is an Adelie penguin breeding colony (about 60,000 pairs) on the island , which BirdLife International has designated as an Important Bird Area (AQ190). Between 1,500 and 5,000 pairs of emperor penguins breed on the sea ice east of Bernacchi Head , a rugged cliff at the extreme southern end of the island (Important Bird Area AQ189).
