The purpose of this work was to identify suitable specimens that can be used for palaeoclimatic reconstructions.

The stalagmites were collected in February and March 2023, and geochemical analyses performed between April and December 2023.","distributionFormats":[{"name":"Comma-separated values (CSV)","type":"text/csv","version":"unknown"}],"distributorContacts":[{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"distributor","email":"info@eidc.ac.uk"}],"funding":[{"funderName":"Natural Environment Research Council","funderIdentifier":"https://ror.org/02b5d8509","awardTitle":"Novel insights into the Northeast Winter Monsoon","awardNumber":"NE/X011771/1","awardURI":"https://gtr.ukri.org/projects?ref=NE/X011771/1","orcid":false,"ror":true}],"id":"f1415ba4-35cd-40db-a717-db6693b03eb0","incomingCitationCount":0,"infoLinks":[{"url":"https://data-package.ceh.ac.uk/sd/f1415ba4-35cd-40db-a717-db6693b03eb0.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"inspireThemes":[{"theme":"Geology","uri":"http://inspire.ec.europa.eu/theme/ge"}],"keywordsOther":[{"value":"palaeoclimate"},{"value":"speleothem"},{"value":"carbon isotopes"},{"value":"oxygen isotopes"},{"value":"stable isotopes"},{"value":"carbonate","uri":"http://www.eionet.europa.eu/gemet/concept/1162"}],"keywordsPlace":[{"value":"Vietnam"}],"keywordsTheme":[{"value":"Climate and climate change","uri":"http://onto.nerc.ac.uk/CEHMD/topic/4"},{"value":"Environmental survey","uri":"http://onto.nerc.ac.uk/CEHMD/topic/7"}],"licences":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"}],"lineage":"Samples were brought to the laboratory from the field and cleaned with deionised water. The stalagmites were cut in half along the growth axis using a diamond wiresaw.  Subsamples for stable isotopes and U-Th dating were collected using a Sherline 2000 micromill. \n\nStable isotope values were calculated based on international standards NBS18 and IAEA60. U-Th ages are reported relative to 1950 CE and assume a Thorium-230/Thorium-232 atomic ratio of 4 (± 2) x 10e-6. Samples were completely dissolved in diluted hydrochloric acid and spiked with a Thorium-229/Uranium-233,236 tracer, after which they were converted to nitric form by boiling nitric acid. The U/Th separations were conducted with extraction chromatography and the final U and Th fractions were measured using a Thermo Scientific Neptune MC-ICPMS.","metadataDate":"2026-05-11T18:20:31","notGEMINI":true,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/data/f1415ba4-35cd-40db-a717-db6693b03eb0","name":"Download the data","description":"Download a copy of this data","function":"download","type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/sd/f1415ba4-35cd-40db-a717-db6693b03eb0.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"pointsOfContact":[{"familyName":"Ersek","givenName":"V.","organisationName":"Northumbria University","organisationIdentifier":"https://ror.org/049e6bc10","role":"pointOfContact","email":"vasile.ersek@northumbria.ac.uk","nameIdentifier":"https://orcid.org/0000-0001-9730-0007","address":{"deliveryPoint":"Sutherland Building,","city":"Newcastle-Upon-Tyne","postalCode":"NE1 8ST","country":"United Kingdom"},"fullName":"Ersek, V.","pointOfContact":"Northumbria University"}],"publicationDate":"2024-07-25T00:00:00.000Z","publishers":[{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/f1415ba4-35cd-40db-a717-db6693b03eb0"},{"code":"10.5285/f1415ba4-35cd-40db-a717-db6693b03eb0","codeSpace":"doi"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"familyName":"Ersek","givenName":"V.","organisationName":"Northumbria University","organisationIdentifier":"https://ror.org/049e6bc10","role":"pointOfContact","email":"vasile.ersek@northumbria.ac.uk","nameIdentifier":"https://orcid.org/0000-0001-9730-0007","address":{"deliveryPoint":"Sutherland Building,","city":"Newcastle-Upon-Tyne","postalCode":"NE1 8ST","country":"United Kingdom"},"fullName":"Ersek, V.","pointOfContact":"Northumbria University"},{"familyName":"Ersek","givenName":"V.","organisationName":"Northumbria University","organisationIdentifier":"https://ror.org/049e6bc10","role":"author","email":"vasile.ersek@northumbria.ac.uk","nameIdentifier":"https://orcid.org/0000-0001-9730-0007","fullName":"Ersek, V."},{"familyName":"Bendle","givenName":"J.","organisationName":"University of Birmingham","organisationIdentifier":"https://ror.org/03angcq70","role":"author","email":"j.bendle@bham.ac.uk","nameIdentifier":"https://orcid.org/0000-0002-6826-8658","fullName":"Bendle, J."},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"},{"organisationName":"Northumbria University","organisationIdentifier":"https://ror.org/049e6bc10","role":"rightsHolder"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"custodian","email":"info@eidc.ac.uk"}],"rightsHolders":[{"organisationName":"Northumbria University","organisationIdentifier":"https://ror.org/049e6bc10","role":"rightsHolder"}],"spatialReferenceSystems":[{"code":"http://www.opengis.net/def/crs/EPSG/0/4326","title":"WGS 84"}],"spatialRepresentationTypes":["textTable"],"title":"Stable isotope and U/Th speleothem measurements from Vietnam, 200,000–334 years BP","topicCategories":[{"value":"climatologyMeteorologyAtmosphere","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/climatologyMeteorologyAtmosphere"},{"value":"geoscientificInformation","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/geoscientificInformation"}],"topics":["http://onto.nerc.ac.uk/CEHMD/topic/4","http://onto.nerc.ac.uk/CEHMD/topic/7"],"type":"dataset","uri":"https://catalogue.ceh.ac.uk/id/f1415ba4-35cd-40db-a717-db6693b03eb0","useConstraints":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"}]}
