Om dit te achterhalen zijn van de houten staken in de waterput monsters genomen voor dendrochronologisch onderzoek.\nHet gaat hier om essenhout (Fraxinus excelsior L.). Het referentiemateriaal voor deze houtsoort is beperkt. Synchronisatie met eik (Quercus spp.) is mogelijk, maar niet gebruikelijk.\nVoor het onderzoek zijn drie monsters aangeleverd. Deze kunnen onderling gedateerd worden en uit de sterke gelijkenis mag geconcludeerd worden dat het om dezelfde boom gaat. Hiervoor is de middelcurve 25.113.B01 gemaakt.\nVoor de IJzertijd is alleen referentiemateriaal voor eik beschikbaar en hiermee kan geen resultaat gevonden worden. Vergelijking met essen materiaal uit de IJzertijd en andere perioden levert eveneens geen resultaat op.\nGezien het lage dateringspercentage van essenhout zijn deze resultaten niet opmerkelijk."},"dsDescriptionDate":{"typeName":"dsDescriptionDate","multiple":false,"typeClass":"primitive","value":"2026-01-26"}}]},{"typeName":"subject","multiple":true,"typeClass":"controlledVocabulary","value":["Arts and Humanities"]},{"typeName":"depositor","multiple":false,"typeClass":"primitive","value":"van Daalen, Sjoerd"},{"typeName":"dateOfDeposit","multiple":false,"typeClass":"primitive","value":"2026-01-26"}]},"dccd":{"displayName":"DCCD Metadata","name":"dccd","fields":[{"typeName":"dccd-projectType","multiple":true,"typeClass":"controlledVocabulary","value":["dating"]},{"typeName":"dccd-category","multiple":false,"typeClass":"controlledVocabulary","value":"archaeology"},{"typeName":"dccd-principalInvestigator","multiple":false,"typeClass":"primitive","value":"Sjoerd van Daalen"},{"typeName":"dccd-objectType","multiple":true,"typeClass":"controlledVocabulary","value":["water well"]},{"typeName":"dccd-elementType","multiple":true,"typeClass":"controlledVocabulary","value":["post"]},{"typeName":"dccd-taxon","multiple":true,"typeClass":"controlledVocabulary","value":["Fraxinus excelsior L."]},{"typeName":"dccd-location","multiple":true,"typeClass":"compound","value":[{"dccd-latitude":{"typeName":"dccd-latitude","multiple":false,"typeClass":"primitive","value":"52.173"},"dccd-longitude":{"typeName":"dccd-longitude","multiple":false,"typeClass":"primitive","value":"4.383"}}]}]},"dansDataVaultMetadata":{"displayName":"Data Vault Metadata","name":"dansDataVaultMetadata","fields":[{"typeName":"dansDataversePid","multiple":false,"typeClass":"primitive","value":"doi:10.34894/YOWTNV"},{"typeName":"dansDataversePidVersion","multiple":false,"typeClass":"primitive","value":"1.0"},{"typeName":"dansBagId","multiple":false,"typeClass":"primitive","value":"urn:uuid:b08e53b0-316f-4170-a4e3-2e2cf7ed8e99"},{"typeName":"dansNbn","multiple":false,"typeClass":"primitive","value":"urn:nbn:nl:ui:13-d4a21296-3c87-46e3-842f-4c13bee4ffda"}]}},"files":[{"label":"25.113.001.JPG","restricted":true,"version":1,"datasetVersionId":33758,"dataFile":{"id":601869,"persistentId":"","filename":"25.113.001.JPG","contentType":"image/jpeg","friendlyType":"JPEG Image","filesize":18719985,"storageIdentifier":"surf://store:19bfaafb6f1-0e683fff0ce1","rootDataFileId":-1,"checksum":{"type":"SHA-1","value":"890c0f9e9339f3725f5515103a9aa2ca6814ade8"},"tabularData":false,"creationDate":"2026-01-26","publicationDate":"2026-01-26","lastUpdateTime":"2026-01-26T15:55:19Z","fileAccessRequest":true}},{"label":"25.113.002.1.JPG","restricted":true,"version":1,"datasetVersionId":33758,"dataFile":{"id":601866,"persistentId":"","filename":"25.113.002.1.JPG","contentType":"image/jpeg","friendlyType":"JPEG Image","filesize":11011344,"storageIdentifier":"surf://store:19bfaafc08b-a4c6a455475d","rootDataFileId":-1,"checksum":{"type":"SHA-1","value":"f2ce71639b4e6772eec3552544cfde6e00d9e952"},"tabularData":false,"creationDate":"2026-01-26","publicationDate":"2026-01-26","lastUpdateTime":"2026-01-26T15:55:19Z","fileAccessRequest":true}},{"label":"25.113.002.2.JPG","restricted":true,"version":1,"datasetVersionId":33758,"dataFile":{"id":601867,"persistentId":"","filename":"25.113.002.2.JPG","contentType":"image/jpeg","friendlyType":"JPEG Image","filesize":15510910,"storageIdentifier":"surf://store:19bfaafc87e-bd24631a88b9","rootDataFileId":-1,"checksum":{"type":"SHA-1","value":"d8ad4c6a269c8e91fb474c6c2f14e237817d0bad"},"tabularData":false,"creationDate":"2026-01-26","publicationDate":"2026-01-26","lastUpdateTime":"2026-01-26T15:55:19Z","fileAccessRequest":true}},{"label":"25.113.003.JPG","restricted":true,"version":1,"datasetVersionId":33758,"dataFile":{"id":601865,"persistentId":"","filename":"25.113.003.JPG","contentType":"image/jpeg","friendlyType":"JPEG Image","filesize":14795173,"storageIdentifier":"surf://store:19bfaafb293-f123d74ef5f1","rootDataFileId":-1,"checksum":{"type":"SHA-1","value":"dffc940c940b531d701bbed034bf6134c4b26b8a"},"tabularData":false,"creationDate":"2026-01-26","publicationDate":"2026-01-26","lastUpdateTime":"2026-01-26T15:55:19Z","fileAccessRequest":true}},{"label":"25.113 rapport Wassenaar -
