This sedimentological, geomorphological and geochronological study aims at better understanding of the taphonomy of the MIS 3 fossil accumulations and their palaeoclimate context. The two sites contain complex types of fossil thanatocoenosis - in situ, secondary or mixt. Numerous methods of investigation, typical for this type of multidisciplinary research were applied: AMS 14C direct dating on fossil bone (N = 42), U/Th dating of the relevant speleothems (N = 4), termoluminiscence for dating sediments (OSL; N=7), analysis of physical and chemical properties of cave sediments, rock magnetism, stable isotope analyses on the cave bear’s bone collagen (δ15N and δ13C; N=125), taphonomic methods for assessing the bone assemblage’s properties (MNI, NISP, ISD, long bone orientation etc.), high resolution osteometry, laser scanning of the cave bear’ bioglyphs etc.","PeriodicalId":30470,"journal":{"name":"GEOREVIEW Scientific Annals of Stefan cel Mare University of Suceava Geography Series","volume":"26 1","pages":"78"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70436672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five PMIP periods have been retained for tier one simulations as part of CMIP6 (coupled model intercomparison project, phase 6): the last millennium, the mid-Holocene (6ka BP), the Last Glacial maximum (21ka BP), the Last Interglacial (127ka BP) and the Pliocene (3 Ma BP). The talk will review the rationale behind these simulations and highlight what would be needed from the paleoclimate community to fully benefit from this huge simulation effort.  The discussion will also discuss how this suite of PMIP4CMIP6 experiments is connected to several other periods and sensitivity experiments as part of PMIP.
