Records were selected based on their length, completeness and resolution, and their age models were updated, where required, by alignment to the LR04 benthic delta (super 18) O stack. The resulting compilation allows comparison of individual glacial to interglacial transitions with confidence, but the level of synchronisation is inadequate for discussion of temporal phasing. The comparison of interglacials and glacials concentrates on the peaks immediately before and after terminations; particularly strong and weak glacials and interglacials have been identified. This confirms that strong interglacials are confined to the last 450 ka, and that this is a globally robust pattern; however weak interglacials (i.e. marine isotope stage 7) can still occur in this later period. Strong glacial periods are also concentrated in the recent half of the records, although marine isotope stage 16 is strong in many delta (super 18) O records. Strong interglacials, particularly in the marine isotopic records, tend to follow strong glacials, suggesting that we should not expect interglacial strength to be strongly influenced by the instantaneous astronomical forcing. Many interglacials have a complex structure, with multiple peaks and troughs whose origin needs to be understood. However this compilation emphasises the under-representation of terrestrial environments and highlights the need for long palaeoclimate records from these areas. The main result of this work is the compiled datasets and maps of interglacial strength which provide a target for modelling studies and for conceptual understanding.completedQuaternary geologyalgaealiphatic hydrocarbonsalkanesAntarcticaArabian SeaAtlantic Oceanbenthic environmentcarbon dioxideCeara RiseCenozoicChatham Riseclastic sedimentsCoccolithophoraceaecoresDeep Sea Drilling Projectdepositional environmentDome CDSDP Site 607East PacificEPICAEquatorial AtlanticEquatorial PacificForaminiferaglacial environmentGorda RiseHolocenehydrocarbonsice coresIndian Oceaninterglacial environmentInvertebrataIPODisotope ratiosisotopesLeg 111Leg 117Leg 130Leg 138Leg 154Leg 162Leg 167Leg 177Leg 181Leg 184Leg 94loesslower HolocenemethanemicrofossilsMid-Atlantic RidgeNorth AtlanticNorth PacificNortheast AtlanticNortheast PacificNorthwest PacificO-18/O-16Ocean Drilling ProgramODP Site 1020ODP Site 1090ODP Site 1123ODP Site 1143ODP Site 1146ODP Site 677ODP Site 722ODP Site 806ODP Site 846ODP Site 925ODP Site 980ODP Site 982ODP Site 983Ontong Java Plateauorganic compoundsoxygenPacific Oceanpaleoclimatologypaleosolspaleotemperatureperiglacial environmentPlantaeProtistaQuaternaryRockall Banksea watersedimentsSouth AtlanticSouth China SeaSouth PacificSoutheast Pacificstable isotopestemperatureWest PacificWilkes Landurn:org.iodp:exp:111urnlargerWorkCitationcampaignurn:org.iodp:exp:117urnlargerWorkCitationcampaignurn:org.iodp:exp:130urnlargerWorkCitationcampaignurn:org.iodp:exp:138urnlargerWorkCitationcampaignurn:org.iodp:exp:154urnlargerWorkCitationcampaignurn:org.iodp:exp:162urnlargerWorkCitationcampaignurn:org.iodp:exp:167urnlargerWorkCitationcampaignurn:org.iodp:exp:177urnlargerWorkCitationcampaignurn:org.iodp:exp:181urnlargerWorkCitationcampaignurn:org.iodp:exp:184urnlargerWorkCitationcampaignurn:org.iodp:exp:94urnlargerWorkCitationcampaignurn:org.iodp:exp:94:site:607urnlargerWorkCitationstudyurn:org.iodp:exp:94urnlargerWorkCitationcampaignurn:org.iodp:exp:167:site:1020urnlargerWorkCitationstudyurn:org.iodp:exp:167urnlargerWorkCitationcampaignurn:org.iodp:exp:177:site:1090urnlargerWorkCitationstudyurn:org.iodp:exp:177urnlargerWorkCitationcampaignurn:org.iodp:exp:181:site:1123urnlargerWorkCitationstudyurn:org.iodp:exp:181urnlargerWorkCitationcampaignurn:org.iodp:exp:184:site:1143urnlargerWorkCitationstudyurn:org.iodp:exp:184urnlargerWorkCitationcampaignurn:org.iodp:exp:184:site:1146urnlargerWorkCitationstudyurn:org.iodp:exp:184urnlargerWorkCitationcampaignurn:org.iodp:exp:111:site:677urnlargerWorkCitationstudyurn:org.iodp:exp:111urnlargerWorkCitationcampaignurn:org.iodp:exp:117:site:722urnlargerWorkCitationstudyurn:org.iodp:exp:117urnlargerWorkCitationcampaignurn:org.iodp:exp:130:site:806urnlargerWorkCitationstudyurn:org.iodp:exp:130urnlargerWorkCitationcampaignurn:org.iodp:exp:138:site:846urnlargerWorkCitationstudyurn:org.iodp:exp:138urnlargerWorkCitationcampaignurn:org.iodp:exp:154:site:925urnlargerWorkCitationstudyurn:org.iodp:exp:154urnlargerWorkCitationcampaignurn:org.iodp:exp:162:site:980urnlargerWorkCitationstudyurn:org.iodp:exp:162urnlargerWorkCitationcampaignurn:org.iodp:exp:162:site:982urnlargerWorkCitationstudyurn:org.iodp:exp:162urnlargerWorkCitationcampaignurn:org.iodp:exp:162:site:983urnlargerWorkCitationstudyurn:org.iodp:exp:162urnlargerWorkCitationcampaignEnglishgeoscientificInformation-171.2956159.2142-41.471016.3719Includes supplement: http://www.clim-past.net/7/361/2011/cp-7-361-2011-supplement.xlsx; published in Climate of the Past Discussion: 15 October 2010, http://www.clim-past-discuss.net/6/2223/2010/cpd-6-2223-2010.html; accessed in Nov., 2011application/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www.clim-past.net/7/361/2011/cp-7-361-2011.pdfdownload
