Individual sample locations (latitude and longitude) are provided in the data file. In total, 18 water and SPM samples were collected from 11 different localities. Samples were collected to span a large salinity range (0.15-29 P.S.U.).

Element concentrations were determined via inductively-coupled plasma optical emission spectroscopy (ICP-OES) on an Agilent 5100 at the Department of Earth Sciences (University of Cambridge). Element concentration uncertainties were determined via repeated measurements of the SPS-SW2, SLRS-6 and IAPSO standards. Suspended particulate matter (SPM) concentrations were made using the volume of water collected and the mass of dried solids. Dissolved inorganic carbon (DIC) isotope measurements were made using a Thermo Gas Bench attached to a Delta V Mass Spectrometer.","metadataDate":"2026-06-29T16:12:10","notGEMINI":true,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/data/7565893d-95ec-4f89-94c5-952457820fa7","name":"Download the data","description":"Download a copy of this data","function":"download","type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/sd/7565893d-95ec-4f89-94c5-952457820fa7.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"pointsOfContact":[{"familyName":"Knight","givenName":"Alasdair","organisationName":"University of Cambridge","role":"pointOfContact","email":"acgk2@cam.ac.uk ","nameIdentifier":"https://orcid.org/0000-0002-3206-3060","fullName":"Knight, A.","pointOfContact":"University of Cambridge"}],"publicationDate":"2024-06-13T00:00:00.000Z","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/7565893d-95ec-4f89-94c5-952457820fa7"},{"code":"10.5285/7565893d-95ec-4f89-94c5-952457820fa7","codeSpace":"doi"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"familyName":"Knight","givenName":"A.C.G.","organisationName":"University of Cambridge","role":"author","email":"acgk2@cam.ac.uk ","nameIdentifier":"https://orcid.org/0000-0002-3206-3060","fullName":"Knight, A.C.G."},{"familyName":"Knight","givenName":"Alasdair","organisationName":"University of Cambridge","role":"pointOfContact","email":"acgk2@cam.ac.uk ","nameIdentifier":"https://orcid.org/0000-0002-3206-3060","fullName":"Knight, A.","pointOfContact":"University of Cambridge"},{"familyName":"Stevenson","givenName":"E.I.","organisationName":"University of Cambridge","role":"author","email":"eis22@cam.ac.uk ","fullName":"Stevenson, E.I."},{"familyName":"Knapp","givenName":"W.","organisationName":"University of Cambridge","role":"author","email":"wjk27@cam.ac.uk ","fullName":"Knapp, W."},{"familyName":"Bridgestock","givenName":"L.","organisationName":"University of Cambridge","role":"author","email":"ljb212@cam.ac.uk ","nameIdentifier":"https://orcid.org/0000-0001-7636-6090","fullName":"Bridgestock, L."},{"familyName":"Tipper","givenName":"E.T.","organisationName":"University of Cambridge","role":"author","email":"ett20@cam.ac.uk ","nameIdentifier":"https://orcid.org/0000-0003-3540-3558","fullName":"Tipper, E.T."},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"custodian","email":"info@eidc.ac.uk"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"},{"organisationName":"University of Cambridge","organisationIdentifier":"https://ror.org/013meh722","role":"rightsHolder"}],"rightsHolders":[{"organisationName":"University of Cambridge","organisationIdentifier":"https://ror.org/013meh722","role":"rightsHolder"}],"spatialReferenceSystems":[{"code":"http://www.opengis.net/def/crs/EPSG/0/4326","title":"WGS 84"}],"spatialRepresentationTypes":["grid"],"spatialResolutions":[{"distance":"10","uom":"urn:ogc:def:uom:EPSG::9001"}],"temporalExtents":[{"begin":"2022-09-11","end":"2022-09-18"}],"title":"Cation and suspended sediment concentrations from the Mackenzie River and Estuary, Canada, September 2022","topicCategories":[{"value":"environment","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/environment"},{"value":"inlandWaters","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/inlandWaters"}],"topics":["http://onto.nerc.ac.uk/CEHMD/topic/6","http://onto.nerc.ac.uk/CEHMD/topic/9","http://onto.nerc.ac.uk/CEHMD/topic/7","http://onto.nerc.ac.uk/CEHMD/topic/16"],"type":"dataset","uri":"https://catalogue.ceh.ac.uk/id/7565893d-95ec-4f89-94c5-952457820fa7","useConstraints":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"}],"version":1}
