Samples were analysed on day of collection or arrival at the laboratory using a Metrohm 702 Titrino autosampler with sample changer. Duplicate samples were analysed at the Institute for Freshwater Ecology (IFE) Windermere for a 12 months period and also at IFE East Stoke to compare results obtained by the laboratories. Alkalinity was also measured as part of the chemical harmonisation programme set up by the IFE at East Stoke. A zip file containing box-and-whisker plots for each determinand, showing the range of values (median, inter-quartile range, 1.5 * inter-quartile range, outliers) recorded at each site is available to enable prospective users of the data to understand data quality. The analysis was carried out by members of the analytical chemistry section at York University (from April 1994 until February 1997).","metadataDate":"2026-06-29T16:32:16","notGEMINI":false,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/sd/73a7ae36-2882-434f-a206-76b848e22d82.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset.","function":"information","type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/data/73a7ae36-2882-434f-a206-76b848e22d82","name":"Download the data","description":"Get a copy of this data","function":"download","type":"OTHER"}],"pointsOfContact":[{"organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"pointOfContact","email":"enquiries@ceh.ac.uk","address":{"deliveryPoint":"Maclean Building, Benson Lane, Crowmarsh Gifford","city":"Wallingford","administrativeArea":"Oxfordshire ","postalCode":"OX10 8BB","country":"United Kingdom"},"pointOfContact":"UK Centre for Ecology & Hydrology"}],"publicationDate":"2014-08-18T00:00:00.000Z","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":"a97dc330-cb83-4b34-b79a-6ceab7fac8cc"}],"resourceIdentifiers":[{"code":"1408369454181","codeSpace":"CEH:EIDC:"},{"code":"https://catalogue.ceh.ac.uk/id/73a7ae36-2882-434f-a206-76b848e22d82"},{"code":"10.5285/73a7ae36-2882-434f-a206-76b848e22d82","codeSpace":"doi"}],"resourceMaintenance":[{"frequencyOfUpdate":"notPlanned","note":"Programme is finished"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"pointOfContact","email":"enquiries@ceh.ac.uk","address":{"deliveryPoint":"Maclean Building, Benson Lane, Crowmarsh Gifford","city":"Wallingford","administrativeArea":"Oxfordshire ","postalCode":"OX10 8BB","country":"United Kingdom"},"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"},{"familyName":"Leach","givenName":"D.","organisationName":"University of York","organisationIdentifier":"https://ror.org/04m01e293","role":"author","email":"enquiries@ceh.ac.uk","fullName":"Leach, D."},{"familyName":"Bachiller-Jareno","givenName":"N.","organisationName":"Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"author","email":"enquiries@ceh.ac.uk","fullName":"Bachiller-Jareno, N."},{"familyName":"Tindall","givenName":"I.","organisationName":"Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"author","email":"enquiries@ceh.ac.uk","fullName":"Tindall, I."},{"familyName":"Moore","givenName":"R.","organisationName":"Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"author","email":"enquiries@ceh.ac.uk","fullName":"Moore, R."},{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"},{"organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"rightsHolder","email":"enquiries@ceh.ac.uk"}],"rightsHolders":[{"organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"rightsHolder","email":"enquiries@ceh.ac.uk"}],"securityConstraints":["unclassified"],"spatialReferenceSystems":[{"code":"http://www.opengis.net/def/crs/EPSG/0/27700","title":"OSGB 1936 / British National Grid"}],"spatialRepresentationTypes":["textTable"],"temporalExtents":[{"begin":"1993-09-07","end":"1997-10-29"}],"title":"Total alkalinity data from rivers [LOIS]","topicCategories":[{"value":"environment","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/environment"}],"topics":["http://onto.nerc.ac.uk/CEHMD/topic/16"],"type":"dataset","uri":"https://catalogue.ceh.ac.uk/id/73a7ae36-2882-434f-a206-76b848e22d82","useConstraints":[{"value":"This resource is made 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"}]}
