Site details
Site description: This Marine IBA is identified using seaward extensions around breeding colonies. It originates from the Japan Exclusive Economic Zone (EEZ) and falls within the Pacific, Northwest FAO ocean region. The site covers an area of 1965 km2 and is 838 km away from the closet coastline. The depth ranges from 70 to 3052 m, mean annual sea surface temperature falls between 24.41 and 24.67 °C and mean annual chlorophyll-a concentrations found to range between 0.09 and 0.11 mg/m3.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
Additional biodiversity: 1 species triggers IBA criteria at this Marine IBA. Seaward extensions around breeding colony; Nishinoshima islet include key near-colony areas for breeding populations of Great Crested Tern (LC).
Delineation rationale: Site identified by applying a colony extension to SitRecId - 15046
