Nine rivers within sub-catchments of contrasting geology (clay, sand, chalk) were investigated. Data were obtained via laboratory incubations (potential data) and direct, field-based measurements (in situ data) in summer 2013. Also included are chemical parameters determined in porewaters prior to in situ rate measurements.","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"}],"id":"d1b08279-68a8-4d93-afa2-576e903cc04d","incomingCitationCount":1,"incomingCitations":[{"description":"Lansdown, K., McKew, B.A., Whitby, C., Heppell, C.M., Dumbrell, A.J., Binley, A., Olde, L. and Trimmer M.

As chemical data were generated, checks were made to ensure accuracy (certified reference materials) and precision (repeat measurements) were within accepted tolerance limits. We also ensured measured values fit within those of calibration standards and, if necessary, re-analysed samples diluted to fall within the calibration range. For data generated via mass spectrometry, beam areas of all measured mass-to-charge ratios were corrected for drift offline using control standards. All data were checked to ensure reported values were above the detection limit of the method. All calculations were checked for errors before data was accepted.","metadataDate":"2026-06-29T16:28:29","notGEMINI":false,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/data/d1b08279-68a8-4d93-afa2-576e903cc04d","name":"Download the data","description":"Download a copy of this data","function":"download","type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/sd/d1b08279-68a8-4d93-afa2-576e903cc04d.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"pointsOfContact":[{"honorificPrefix":"Dr","familyName":"Lansdown","givenName":"Katrina","organisationName":"Queen Mary University of London","organisationIdentifier":"https://ror.org/026zzn846","role":"pointOfContact","email":"katrina.lansdown@gmail.com","address":{"deliveryPoint":"School of Biological and Chemical Sciences, Mile End Road","city":"London","postalCode":"E1 4NS","country":"UK"},"fullName":"Lansdown, K.","pointOfContact":"Queen Mary University of London"}],"publicationDate":"2016-08-17T00:00:00.000Z","publishers":[{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"relationships":[{"relation":"http://purl.org/dc/terms/isPartOf","target":"a6c8e7c5-4c1a-43ef-9f0b-504b96549d7d"}],"resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/d1b08279-68a8-4d93-afa2-576e903cc04d"},{"code":"10.5285/d1b08279-68a8-4d93-afa2-576e903cc04d","codeSpace":"doi"}],"resourceMaintenance":[{"frequencyOfUpdate":"notPlanned"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"honorificPrefix":"Dr","familyName":"Lansdown","givenName":"Katrina","organisationName":"Queen Mary University of London","organisationIdentifier":"https://ror.org/026zzn846","role":"pointOfContact","email":"katrina.lansdown@gmail.com","address":{"deliveryPoint":"School of Biological and Chemical Sciences, Mile End Road","city":"London","postalCode":"E1 4NS","country":"UK"},"fullName":"Lansdown, K.","pointOfContact":"Queen Mary University of London"},{"familyName":"Lansdown","givenName":"K.","organisationName":"Queen Mary University of London","organisationIdentifier":"https://ror.org/026zzn846","role":"author","email":"katrina.lansdown@gmail.com","fullName":"Lansdown, K."},{"familyName":"Heppell","givenName":"C.
