Notes from the SISAL database: PU-2 (SISAL entity_id = 184): The upper three dating points (dating_id = 2723, 2724 and 2725) and the respective interp_age do not reproduce the figure from the paper. The author has been asked for help but this question has not been answered in a satisfying way. The sample was collected in 1977. In the original paper, the model was linear but the data the author provided was obtained with a linear between dates model. It is not actively growing when collected. The chronology (Onac et al., 2002) is no longer valid. New U-Th data shows no hiatus and a different time range. The new U-Th and isotope data will be submitted for publication at the end of 2022 as Dragusin et al. #----------------------------------------- # Publication # Authors: Onac, Bogdan Petroniu; Silviu Constantin; Joyce Lundberg; Stein‐Erik Lauritzen # Published_Date_or_Year: 2002 # Published_Title: Isotopic climate record in a Holocene stalagmite from Ursilor Cave (Romania) # Journal_Name: Journal of Quaternary Science # Volume: 17 # Edition: # Issue: 4 # Pages: 319-327 # Report_Number: # DOI: 10.1002/jqs.685 # Online_Resource: # Full_Citation: Onac, B.

A lack of high-quality reconstructions of past hydroclimate has recently been identified as a critical research gap. Speleothems, with their precise chronologies, widespread distribution, and ability to record changes in local to regional hydroclimate variability, are an ideal source of such information. Here, we present a new version of the Speleothem Isotopes Synthesis and AnaLysis database (SISALv3), which has been expanded to include trace element ratios and Sr isotopes as additional, hydroclimate-sensitive geochemical proxies. The oxygen and carbon isotope data included in previous versions of the database have been substantially expanded. SISALv3 contains speleothem data from 365 sites from across the globe, including 95 , 85 , 52 , 25 , 29 , and 14 Sr-isotope records. The database also has increased spatiotemporal coverage for stable oxygen (892) and carbon (620) isotope records compared with SISALv2 (which consists of 673 and 430 stable oxygen and carbon records, respectively). Additional meta information has been added to improve the machine-readability and filtering of data. Standardized chronologies are included for all new entities along with the originally published chronologies. Thus, the SISALv3 database constitutes a unique resource of speleothem palaeoclimate information that allows regional to global palaeoclimate analyses based on multiple geochemical proxies, permitting more robust interpretations of past hydroclimate and comparisons with isotope-enabled climate models and other Earth system and hydrological models. The database can be accessed at https://doi.org/10.5287/ora-2nanwp4rk (Kaushal et al., 2024). #----------------------------------------- # Funding_Agency # Funding_Agency_Name: # Grant: #----------------------------------------- # Site_Information # Site_Name:Ursilor Cave # Location:Romania # Northernmost_Latitude:46.5537 # Southernmost_Latitude:46.5537 # Easternmost_Longitude:22.5695 # Westernmost_Longitude:22.5695 # Elevation_m:482 #----------------------------------------- # Data_Collection # Collection_Name: PU-2 isotopes Onac2002 SISAL v3 # First_Year: 7068 # Last_Year: -50 # Time_Unit: Cal Yr BP # Core_Length_m: # Parameter_Keywords: oxygen isotopes, carbon isotopes # Notes: Contact: István G.
