The '''[[Antarctic petrel]]''' is a boldly marked dark brown and white petrel, found in [[Antarctica]], most commonly in the [[Ross Sea|Ross]] and [[Weddell Sea]]s. They eat [[Antarctic krill]], fish, and small squid. They feed while swimming but can dive from both the surface and the air.
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.


The Antarctic petrel is the only known species in the genus ''Thalassoica'', and is a member of the family Procellariidae, and the Procellariiformes order. Also, this petrel along with the [[snow petrel]], the [[Cape petrel]], both giant petrels, and the two species in the Fulmarus family, are considered to be a separate group from the other Procellariidae members. They share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns. Although the nostrils on the petrels are on the top of the upper bill. The bills of Procellariiformes are also unique in that they are split into between seven and nine horny plates.
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 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.
