The Backer Islands are a chain of small islands at the south side of Cranton Bay. The islands trend northwest for 22 kilometers (12 nmi) from the ice shelf which forms the southern limit of the bay.

In 2011, scientists from the POLar Earth-observing NETwork (POLENET) traveled to the Backer Islands via a Twin Otter aircraft and installed a GPS monitoring site. This equipment is used to remotely monitor GPS and seismic data that will help scientists determine trends in ice sheet movement and other geophysical phenomena.

-The '''[[humpback whale]]''' is a species of baleen whale. One of the larger rorqual species, adults range in length from 12–16 m (39–52 ft) and weigh about 36,000 kg (79,000 lb). The humpback has a distinctive body shape, with long pectoral fins and a knobbly head. It is known for breaching and other distinctive surface behaviors, making it popular with whale watchers. Males produce a complex song lasting 10 to 20 minutes, which they repeat for hours at a time. Its purpose is not clear, though it may have a role in mating.
+The '''[[Backer Islands]]''' are a chain of small islands at the south side of [[Cranton Bay]]. The islands trend northwest for 22 kilometers (12 nmi) from the [[ice shelf]] which forms the southern limit of the bay.
-Found in oceans and seas around the world, humpback whales typically migrate up to 25,000 km (16,000 mi) each year. Humpbacks feed in [[Southern Ocean|polar waters]], and migrate to tropical or subtropical waters to breed and give birth when they fast and live off their fat reserves. Their diet consists mostly of [[krill]] and small fish. Humpbacks have a diverse repertoire of feeding methods, including the bubble net technique. Like other large whales, the humpback was a target for the [[whaling]] industry. Once hunted to the brink of extinction, its population fell by an estimated 90% before a 1966 moratorium.

This equipment is used to remotely monitor GPS and seismic data that will help scientists determine trends in ice sheet movement and other geophysical phenomena.
