The cooling by 5°C from 21 ka to 12.8 ka implies the equatorward shift of the subarctic boundary in the northwestern Pacific by ~2.8° in latitude. This shift was a result of the stronger summer Okhotsk High. The Okhotsk High was likely enhanced by the combined effects of El NiFo-like conditions in the tropical Pacific and the heating of the land surface of northeastern Siberia.","pubRank":"1"}],"site":[{"NOAASiteId":"19275","siteName":"MD01-2421","siteCode":null,"mappable":"Y","locationName":"Ocean>Pacific Ocean>North Pacific Ocean","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["36.02","141.78"]},"properties":{"southernmostLatitude":"36.02","northernmostLatitude":"36.02","westernmostLongitude":"141.78","easternmostLongitude":"141.78","minElevationMeters":"-2224","maxElevationMeters":"-2224"}},"paleoData":[{"dataTableName":"MD01-2421 Uk37 Yamamoto2005","NOAADataTableId":"34988","earliestYear":144090,"mostRecentYear":240,"timeUnit":"cal yr BP","earliestYearBP":144090,"mostRecentYearBP":240,"earliestYearCE":-142140,"mostRecentYearCE":1710,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/contributions_by_author/yamamoto2005/yamamoto2005.txt","urlDescription":"Original Data and Full Metadata","linkText":"yamamoto2005.txt","variables":[{"cvDataType":"CLIMATE RECONSTRUCTIONS|PALEOCEANOGRAPHY","cvWhat":"earth system variable>temperature variable>temperature>sea water temperature>sea surface temperature","cvMaterial":"reconstruction material>organic compound index>alkenone unsaturation index","cvError":null,"cvUnit":"temperature unit>degree Celsius","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"depth variable>depth","cvMaterial":null,"cvError":null,"cvUnit":"length unit>centimeter","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"age variable>age","cvMaterial":null,"cvError":null,"cvUnit":"time unit>age unit>calendar kiloyear before present","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"chemical composition>compound>organic compound>organic compound index>alkenone unsaturation index>alkenone unsaturation index Uk37 prime","cvMaterial":null,"cvError":null,"cvUnit":"dimensionless","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null}],"NOAAKeywords":["earth science>paleoclimate>paleocean"]}]}]}],"reference":{"pastThesaurusSkos":"https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf","pastThesaurusExplorer":"https://www.ncei.noaa.gov/access/paleo-search/cvterms","gcmdKeywordThesaurus":"https://earthdata.nasa.gov/earth-observation-data/find-data/idn/gcmd-keywords"},"dataLicenseDescription":null,"dataLicenseUrl":null}
