Unlike ice age reductions in AABW, the interglacial stagnation event appears decoupled from open ocean conditions and may have resulted from coastal freshening due to mass loss from the Antarctic ice sheet. AABW reduction coincided with increased North Atlantic Deep Water (NADW) formation, and the subsequent reinvigoration in AABW coincided with reduced NADW formation. Thus, alternation of deep water formation between the Antarctic and the North Atlantic, believed to characterize ice ages, apparently also occurs in warm climates.","pubRank":"1"}],"site":[{"NOAASiteId":"19271","siteName":"ODP 1094","siteCode":null,"mappable":"Y","locationName":"Ocean>Atlantic Ocean>South Atlantic Ocean","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["-53.18035","5.130333"]},"properties":{"southernmostLatitude":"-53.18035","northernmostLatitude":"-53.18035","westernmostLongitude":"5.130333","easternmostLongitude":"5.130333","minElevationMeters":"-2807","maxElevationMeters":"-2807"}},"paleoData":[{"dataTableName":"ODP1094 Hayes14","NOAADataTableId":"27734","earliestYear":158990,"mostRecentYear":118121,"timeUnit":"cal yr BP","earliestYearBP":158990,"mostRecentYearBP":118121,"earliestYearCE":-157040,"mostRecentYearCE":-116171,"coreLengthMeters":null,"dataTableNotes":"Depths given are composite depths for combined drill holes.","species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/contributions_by_author/hayes2014/hayes2014.txt","urlDescription":"Formatted Text File","linkText":"ODP1094 Data","variables":[{"cvDataType":"CLIMATE RECONSTRUCTIONS|PALEOCEANOGRAPHY","cvWhat":"earth system variable>temperature variable>temperature>sea water temperature>sea surface temperature","cvMaterial":null,"cvError":null,"cvUnit":"temperature unit>degree Celsius","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"based on the marine lipid index TEX-86L calibration of Kim et al.
