The data were collected on seven monthly to bimonthly visits during 2013 and comprise methane ebullition fluxes measured using inverted funnels, and methane fluxes measured using static chambers. The tall, static chambers captured methane transported by diffusion, plant-mediated transport and steady ebullition, whereas the inverted funnels captured methane transported by steady and episodic ebullition. The dataset also includes measurements of water level and meteorological variables (net radiation, soil temperature, air pressure) along with an allometric measure of plant biomass (Vascular Green Area).","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"}],"funding":[{"funderName":"Natural Environment Research Council","funderIdentifier":"https://ror.org/02b5d8509","awardNumber":"NEC04526 ","orcid":false,"ror":true}],"id":"8d42ea20-6e8f-4b39-a735-8a6b3b95984e","incomingCitationCount":0,"infoLinks":[{"url":"https://data-package.ceh.ac.uk/sd/8d42ea20-6e8f-4b39-a735-8a6b3b95984e.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"inspireThemes":[{"theme":"Habitats and Biotopes","uri":"http://inspire.ec.europa.eu/theme/hb"}],"keywordsOther":[{"value":"ebullition"},{"value":"peatlands"},{"value":"methane","uri":"http://www.eionet.europa.eu/gemet/concept/5199"},{"value":"peat","uri":"http://www.eionet.europa.eu/gemet/concept/6081"},{"value":"fen","uri":"http://www.eionet.europa.eu/gemet/concept/3154"},{"value":"floodplain","uri":"http://www.eionet.europa.eu/gemet/concept/15370"}],"keywordsTheme":[{"value":"Climate and climate change","uri":"http://onto.nerc.ac.uk/CEHMD/topic/4"},{"value":"Pollution","uri":"http://onto.nerc.ac.uk/CEHMD/topic/15"}],"licences":[{"value":"This resource is made available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"}],"lineage":"Fieldwork measurements were made following the protocols developed by Defra project SP1210 'Lowland Peatland Systems in England and Wales'. Methane ebullition fluxes were measured using twelve inverted glass funnels at each site. Chamber methane fluxes were measured using six tall, static chambers at each site to capture diffusion, plant-mediated transport and steady ebullition. Measurements were taken within a 0.04 km2 area at each site in vegetation dominated by Phragmites australis. At each site an automatic weather station (MiniMet, Skye Instruments, UK) was used to measure meteorological variables. Six pressure transducers (Levelogger Gold, Solinst, Canada) were installed in dipwells adjacent to each static chamber collar to measure water level. Manual dips taken on a monthly basis were used to calibrate the pressure transducer data. Vascular Green Area was monitored non-destructively within each chamber collar. Measurements of methane concentration in funnels and static chambers were made by gas chromatography coupled with flame ionization detector. The analytical instrument was calibrated each run and certified gases were used to ensure accuracy.","metadataDate":"2026-06-29T17:09:53","notGEMINI":false,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/sd/8d42ea20-6e8f-4b39-a735-8a6b3b95984e.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/8d42ea20-6e8f-4b39-a735-8a6b3b95984e","name":"Download the data","description":"Download a copy of this data","function":"download","type":"OTHER"}],"pointsOfContact":[{"honorificPrefix":"Professor","familyName":"Heppell","givenName":"Kate","organisationName":"Queen Mary University of London","organisationIdentifier":"https://ror.org/026zzn846","role":"pointOfContact","email":"c.m.heppell@qmul.ac.uk","nameIdentifier":"https://orcid.org/0000-0001-6028-1359","address":{"city":"London","country":"UK"},"fullName":"Heppell, K.","pointOfContact":"Queen Mary University of London"}],"publicationDate":"2018-02-09T00:00:00.000Z","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/8d42ea20-6e8f-4b39-a735-8a6b3b95984e"},{"code":"10.5285/8d42ea20-6e8f-4b39-a735-8a6b3b95984e","codeSpace":"doi"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"honorificPrefix":"Professor","familyName":"Heppell","givenName":"Kate","organisationName":"Queen Mary University of London","organisationIdentifier":"https://ror.org/026zzn846","role":"pointOfContact","email":"c.m.heppell@qmul.ac.uk","nameIdentifier":"https://orcid.org/0000-0001-6028-1359","address":{"city":"London","country":"UK"},"fullName":"Heppell, K.","pointOfContact":"Queen Mary University of London"},{"familyName":"Heppell","givenName":"C.
