Cette table fournit des métadonnées pour l'indicateur réel disponible à partir des statistiques US les plus proches de l'indicateur SDG global correspondant. Veuillez noter que même lorsque l'indicateur global des ODD est entièrement disponible à partir des statistiques US, ce tableau devrait être consulté pour obtenir des informations sur la méthodologie nationale et d'autres informations sur les métadonnées spécifiques à un pays_adjectif.
Actual indicator available | Percent of U.S waters in an MPA |

Actual indicator available - description | Percent of U.S. marine waters in a natural or cultural heritage marine protected area |
Date of national source publication | Fall 2017 |
Method of computation | The indicator is computed by dividing the total number of KBAs wholly covered by protected areas by the total number of KBAs in each country, and multiplying by 100. 'Wholly protected' is defined as >98% coverage to allow for resolution and digitisation errors in the underlying spatial datasets. |
Periodicity | Annual, as needed |
Scheduled update by national source | Annual, as needed |
U.S. method of computation | Area coverage of all U.S. natural and cultural heritage MPAs relative to total area of U.S. marine waters Including bays, estauries and Great Lakes). Protected areas that include terrestrial areas are clipped to include only marine portion in area statistics. |
Comments and limitations | Based on national scale GIS-based area calculations (using the World Eckert IV projection, an equal-area pseudocylindrical map projection). |
