This Worldview of the UN Atlas of the Oceans presents material by geographic areas.
Geographic search
The interactive world map allows a geographic search of all topics and knowledge objects in the UN Atlas. Geographic areas have been developed using the AGROVOC Thesaurus, published by the Food and Agriculture Organization of the United Nations (FAO), as a global standard.
Boundaries and names shown and the designations used on the map do not imply official endorsement or acceptance by the United Nations.

Most carbon dioxide released into the atmosphere as a result of the burning of fossil fuels will eventually be absorbed by the ocean, with potentially adverse consequences for marine biota. Here we quantify the changes in ocean pH that may result from this continued release of CO2 and compare these with pH changes estimated from geological and historical records. We find that oceanic absorption of CO2 from fossil fuels may result in larger pH changes over the next several centuries than any inferred from the geological record of the past 300 million years, with the possible exception of those resulting from rare, extreme events such as bolide impacts or catastrophic methane hydrate degassing.
