To minimise risk of carbon contamination, all equipment used during sampling and processing was new or acid-washed and all samples were managed in a radiocarbon tracer-free laboratory. For the Ribble, Conwy and Dee sites samples were collected during high-flow events. For the Avon, which has a much less flashy flow regime, they were taken at regular intervals throughout one year. High flow events were identified from daily river levels measured at gauging stations near the sampling sites, and made available on-line by the Environment Agency of England and Wales and the Scottish Environment Protection Agency. During the period October 2013-October 2014, four samples were taken for most of the sites, but only three each at the Gairn and Dee A sites. Additional 500 or 1000 mL samples were collected for the determination of SPMconcentration and the carbon content of the SPM.","metadataDate":"2026-06-29T17:24:58","notGEMINI":false,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/data/4962468f-54c4-49ff-adb8-03e9e88cffdd","name":"Download the data","description":"Download a copy of this data","function":"download","type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/sd/4962468f-54c4-49ff-adb8-03e9e88cffdd.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"pointsOfContact":[{"honorificPrefix":"Dr","familyName":"Adams","givenName":"Jess","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"pointOfContact","email":"enquiries@ceh.ac.uk","address":{"deliveryPoint":"Lancaster Environment Centre, Library Avenue, Bailrigg","city":"Lancaster","administrativeArea":"Lancashire","postalCode":"LA1 4AP","country":"United Kingdom"},"fullName":"Adams, J.","pointOfContact":"UK Centre for Ecology & Hydrology"}],"publicationDate":"2020-02-13T00:00:00.000Z","publishers":[{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/4962468f-54c4-49ff-adb8-03e9e88cffdd"},{"code":"10.5285/4962468f-54c4-49ff-adb8-03e9e88cffdd","codeSpace":"doi"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"familyName":"Adams","givenName":"J.","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"author","email":"enquiries@ceh.ac.uk","nameIdentifier":"https://orcid.org/0000-0003-1825-0537","fullName":"Adams, J."},{"familyName":"Tipping","givenName":"E.","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"author","email":"enquiries@ceh.ac.uk","nameIdentifier":"https://orcid.org/0000-0001-6618-6512","fullName":"Tipping, E."},{"familyName":"Bryant","givenName":"C.L.","organisationName":"NERC Radiocarbon Facility","role":"author","email":"charlotte.bryant@glasgow.ac.uk","fullName":"Bryant, C.L."},{"familyName":"Helliwell","givenName":"R.C.","organisationName":"The James Hutton Institute","organisationIdentifier":"https://ror.org/03rzp5127","role":"author","email":"Rachel.helliwell@hutton.ac.uk","fullName":"Helliwell, R.C."},{"familyName":"Quinton","givenName":"J.","organisationName":"Lancaster University","organisationIdentifier":"https://ror.org/4f2nsd36","role":"author","email":"j.quinton@lancaster.ac.uk","address":{"city":"Lancaster","country":"UK"},"fullName":"Quinton, J."},{"honorificPrefix":"Dr","familyName":"Adams","givenName":"Jess","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"pointOfContact","email":"enquiries@ceh.ac.uk","address":{"deliveryPoint":"Lancaster Environment Centre, Library Avenue, Bailrigg","city":"Lancaster","administrativeArea":"Lancashire","postalCode":"LA1 4AP","country":"United Kingdom"},"fullName":"Adams, J.","pointOfContact":"UK Centre for Ecology & Hydrology"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"custodian","email":"info@eidc.ac.uk"},{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"spatialReferenceSystems":[{"code":"http://www.opengis.net/def/crs/EPSG/0/27700","title":"OSGB 1936 / British National Grid"}],"spatialRepresentationTypes":["textTable"],"spatialResolutions":[{"distance":"1000","uom":"urn:ogc:def:uom:EPSG::9001"}],"temporalExtents":[{"begin":"2013-01-01","end":"2014-12-31"}],"title":"Freshwater particulate organic radiocarbon for four major UK catchments, 2013-2014","topicCategories":[{"value":"inlandWaters","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/inlandWaters"}],"topics":["http://onto.nerc.ac.uk/CEHMD/topic/7"],"type":"dataset","uri":"https://catalogue.ceh.ac.uk/id/4962468f-54c4-49ff-adb8-03e9e88cffdd","useConstraints":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"},{"value":"© UK Centre for Ecology & Hydrology","code":"copyright"}]}
