Each data point corresponds to a flux-run of a duration of ~1 minute.  Bulk variables are averaged (mean) along each flux-run, unless otherwise stated in variable description. The sea-ice fraction and melt-pond fraction are from subjectively analysed video footage, where the fraction of sea ice and melt ponds are recorded every minute. Fractions are recorded to the nearest 5% and benchmarked by objective image color analysis of still images. The data set was compiled by Miriam Bennett, with help from Ian Renfrew and Chris Barrell (all University of East Anglia).","keywords":"MASIN, sea ice, melt pond, NE/T006773/1","publicationState":"published","dataPublishedTime":"2026-05-20T09:41:20","doiPublishedTime":null,"updateFrequency":"notPlanned","status":"completed","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/45949/?format=json","dataPath":"/badc/arcticcyclones/data/ASC_sea_ice_and_melt_pond_fraction","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":82132,"numberOfFiles":3,"fileFormat":"ASCII text"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/13191/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/5153/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/4385/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/18405/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/18408/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/50340/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/92544/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/93410/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/93411/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/93412/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/93413/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/93414/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/93415/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/93416/?format=json"],"dataLineage":"These data were produced by the project team and the output data were then supplied to CEDA for archiving.","removedDataTime":null,"removedDataReason":"","language":"English","identifier_set":[],"projects":["https://catalogue.ceda.ac.uk/api/v2/projects/41265/?format=json"],"observationcollection_set":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/219560/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/219551/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/219552/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/219553/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/219554/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/219555/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/219556/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/219557/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/219559/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/219550/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/219558/?format=json"],"procedureAcquisition":"https://catalogue.ceda.ac.uk/api/v2/acquisitions/45950/?format=json","procedureCompositeProcess":null,"procedureComputation":null,"permissions":[{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/2522/?format=json","useLimitation":null,"accessConstraints":null,"accessCategory":"registered","accessRoles":null,"label":"registered: None group","licenceURL":"http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/","licenceClassifications":"any"}],"discoveryKeywords":[]}
