Site description
Gibbon Bay lies between Rayner Point and The Turret on the northeastern coast of Coronation Island. The IBA qualifies on the basis of the concentration of seabirds present (in particular Chinstrap Penguin (Pygoscelis antarctica)) and comprises ice-free areas along the shoreline of Gibbon Bay, including the intervening marine and ice-covered areas.

Information on the environment at Gibbon Bay is not available. In contrast to Signy Island, northern Coronation Island is more susceptible to fog as a result of moisture-heavy prevailing north-westerly winds rising over the permanently ice-covered mountains on Coronation Island.

The nearest research station to the site is Signy (GBR), located on the eastern coast of Signy Island. See IBA Signy Island for more information on this station.

Key biodiversity

Approximately 13 210 pairs of Chinstrap Penguin were recorded breeding along the shoreline of Gibbon Bay in 1983 (Poncet & Poncet 1985), located on ice-free areas at Rayner Point, The Turret and along the shoreline between these two headlands. Snow Petrels (Pagodroma nivea) are reported to breed in at least three locations along the shore of Gibbon Bay (Croxall et al. 1995).

Non-bird biodiversity: None known.
