As atmospheric carbon dioxide increases, the concentration of carbonic acid in seawater also increases, causing a decrease in ocean pH and carbonate mineral saturation states, a process known as ocean acidification. The oceans have absorbed approximately 525 billion tons of carbon dioxide from the atmosphere, or about one-quarter to one-third of the anthropogenic carbon emissions released since the beginning of the Industrial Revolution (Sabine and others, 2004). Global surveys of ocean chemistry have revealed that seawater pH has decreased by about 0.1 units (from a pH of 8.2 to 8.1) since the 1700s due to absorption of carbon dioxide (Caldeira and Wickett, 2003; Orr and others, 2005; Raven and others, 2005). Modeling studies, based on Intergovernmental Panel on Climate Change (IPCC) CO2 emission scenarios, predict that atmospheric carbon dioxide levels could reach more than 500 parts per million (ppm) by the middle of this century and 800 ppm by the year 2100, causing an additional decrease in surface water pH of 0.3 pH units. Ocean acidification is a global threat and is already having profound and deleterious effects on the geology, biology, chemistry, and socioeconomic resources of coastal and marine habitats (Raven and others, 2005; Ruttiman, 2006). The polar and sub-polar seas have been identified as the bellwethers for global ocean acidification.", "description": "HTML Document", "publisher": {"@type": "Organization", "name": "U.S. Geological Survey"}, "author": [{"@type": "Person", "name": "Yates, Kimberly K. kyates@usgs.gov", "givenName": "Kimberly K.", "familyName": "Yates", "email": "kyates@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0001-8764-0358", "url": "https://orcid.org/0000-0001-8764-0358"}, "affiliation": [{"@type": "Organization", "name": "St. Petersburg Coastal and Marine Science Center", "url": "https://www.usgs.gov/centers/spcmsc"}]}, {"@type": "Person", "name": "Robbins, Lisa L. lrobbins@usgs.gov", "givenName": "Lisa L.", "familyName": "Robbins", "email": "lrobbins@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0003-3681-1094", "url": "https://orcid.org/0000-0003-3681-1094"}, "affiliation": [{"@type": "Organization", "name": "St. Petersburg Coastal and Marine Science Center", "url": "https://www.usgs.gov/centers/spcmsc"}]}, {"@type": "Person", "name": "Buczkowski, Brian J. bbuczkowski@usgs.gov", "givenName": "Brian J.", "familyName": "Buczkowski", "email": "bbuczkowski@usgs.gov", "affiliation": [{"@type": "Organization", "name": "Woods Hole Coastal and Marine Science Center", "url": "https://www.usgs.gov/centers/woods-hole-coastal-and-marine-science-center"}]}, {"@type": "Person", "name": "Knorr, Paul O. pknorr@usgs.gov", "givenName": "Paul O.", "familyName": "Knorr", "email": "pknorr@usgs.gov", "affiliation": [{"@type": "Organization", "name": "St. Petersburg Coastal and Marine Science Center", "url": "https://www.usgs.gov/centers/spcmsc"}]}, {"@type": "Person", "name": "Wynn, Jonathan", "givenName": "Jonathan", "familyName": "Wynn"}, {"@type": "Person", "name": "Lisle, John", "givenName": "John", "familyName": "Lisle"}, {"@type": "Person", "name": "Moore, Barbara", "givenName": "Barbara", "familyName": "Moore"}, {"@type": "Person", "name": "Mayer, Larry", "givenName": "Larry", "familyName": "Mayer"}, {"@type": "Person", "name": "Byrne, Robert H.", "givenName": "Robert H.", "familyName": "Byrne"}, {"@type": "Person", "name": "Liu, Xuewu", "givenName": "Xuewu", "familyName": "Liu"}, {"@type": "Person", "name": "Armstrong, Andrew", "givenName": "Andrew", "familyName": "Armstrong"}], "funder": [{"@type": "Organization", "name": "St. Petersburg Coastal and Marine Science Center", "url": "https://www.usgs.gov/centers/spcmsc"}], "spatialCoverage": [{"@type": "Place", "additionalType": "unknown", "name": "Arctic Ocean", "url": "https://geonames.org/2960860"}, {"@type": "Place", "geo": [{"@type": "GeoShape", "additionalProperty": {"@type": "PropertyValue", "name": "GeoJSON", "value": {"type": "FeatureCollection", "features": [{"type": "Feature", "properties": {}, "geometry": {"type": "Polygon", "coordinates": [[[-180.0, 70.0], [-180.0, 90.0], [180.0, 90.0], [180.0, 70.0], [-180.0, 70.0]]]}}]}}}, {"@type": "GeoCoordinates", "latitude": 80.0, "longitude": -0.0}]}]}
