These variations occurred with periodicities similar to those of solar activity and appear to be coherent with time series of the cosmogenic nuclides 14C and 10Be as well as North Atlantic drift ice. Our results imply that small variations in solar irradiance induced pronounced cyclic changes in northern high-latitude environments. They also provide evidence that centennial-scale shifts in the Holocene climate were similar between the subpolar regions of the North Atlantic and North Pacific, possibly because of Sun-ocean-climate linkages.","pubRank":"1"}],"site":[{"NOAASiteId":"22948","siteName":"Arolik Lake","siteCode":null,"mappable":"Y","locationName":"Continent>North America>United States Of America>Alaska","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["59.967","-161.116"]},"properties":{"southernmostLatitude":"59.967","northernmostLatitude":"59.967","westernmostLongitude":"-161.116","easternmostLongitude":"-161.116","minElevationMeters":"145","maxElevationMeters":"145"}},"paleoData":[{"dataTableName":"Arolik Lake Core AROLIKAK Silica","NOAADataTableId":"12518","earliestYear":15112,"mostRecentYear":2305,"timeUnit":"cal yr BP","earliestYearBP":15112,"mostRecentYearBP":2305,"earliestYearCE":-13162,"mostRecentYearCE":-355,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/paleolimnology/northamerica/usa/alaska/arolik2003.txt","urlDescription":"Data","linkText":"arolik2003.txt","variables":[{"cvDataType":"PALEOLIMNOLOGY","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":"age_calkaBP"},{"cvDataType":"PALEOLIMNOLOGY","cvWhat":"depth variable>depth","cvMaterial":null,"cvError":null,"cvUnit":"length unit>centimeter","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"tephras removed from depth","cvFormat":"Numeric","cvShortName":"depth_cm"},{"cvDataType":"PALEOLIMNOLOGY","cvWhat":"chemical composition>compound>inorganic compound>silicon dioxide>biogenic silica","cvMaterial":"geological material>bulk geological material>sediment>dry sediment","cvError":null,"cvUnit":"concentration unit>mass fraction unit>milligram per gram","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"Bsi_Raw"},{"cvDataType":"PALEOLIMNOLOGY","cvWhat":"chemical composition>compound>inorganic compound>silicon dioxide>biogenic silica","cvMaterial":"geological material>bulk geological material>sediment>dry sediment","cvError":null,"cvUnit":"concentration unit>mass fraction unit>milligram per gram","cvSeasonality":null,"cvDetail":"smoothed","cvMethod":null,"cvAdditionalInfo":"3 point running average","cvFormat":"Numeric","cvShortName":"Bsi_3pt"},{"cvDataType":"PALEOLIMNOLOGY","cvWhat":"chemical composition>compound>inorganic compound>silicon dioxide>biogenic silica","cvMaterial":"geological material>bulk geological material>sediment>dry sediment","cvError":null,"cvUnit":"concentration unit>mass fraction unit>milligram per gram","cvSeasonality":null,"cvDetail":"detrended|smoothed","cvMethod":null,"cvAdditionalInfo":"3 point running average","cvFormat":"Numeric","cvShortName":"BSi_3pt_detrend"}],"NOAAKeywords":["earth science>paleoclimate>paleolimnology>geochemistry"]},{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/paleolimnology/northamerica/usa/alaska/arolik2003.xls","urlDescription":"Data","linkText":"arolik2003.xls","variables":[],"NOAAKeywords":["earth science>paleoclimate>paleolimnology>geochemistry"]}]}]}],"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}
