NDVI provides a proxy for the amount and/or the relative 'greenness' of vegetation. \n\nData collection was carried out at six intertidal sites in the winter and summer of 2013. Three of the sites were in Morecambe Bay, North West England and three of the sites were in Essex, South East England, each of these sites consisted of a saltmarsh area and adjacent mudflat area, twenty two sampling quadrats were placed on each area. A single NDVI observation was taken at each quadrat.\n\nSpectral reflectance was measured using a portable spectrometer.\n\nThis data was collected as part of Coastal Biodiversity and Ecosystem Service Sustainability (CBESS): NE/J015644/1. The project was funded with support from the Biodiversity and Ecosystem Service Sustainability (BESS) programme. BESS is a six-year programme (2011-2017) funded by the UK Natural Environment Research Council (NERC) and the Biotechnology and Biological Sciences Research Council (BBSRC) as part of the UK's Living with Environmental Change (LWEC) programme.","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":"NE/J015644/1","awardURI":"https://gtr.ukri.org/projects?ref=NE/J015644/1","orcid":false,"ror":true}],"id":"75b1f669-66b3-472b-9d31-eda908826e17","incomingCitationCount":0,"infoLinks":[{"url":"https://data-package.ceh.ac.uk/sd/75b1f669-66b3-472b-9d31-eda908826e17.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":"NDVI"},{"value":"mudflat"},{"value":"spectral reflectance"},{"value":"salt marsh","uri":"http://www.eionet.europa.eu/gemet/concept/7396"},{"value":"vegetation","uri":"http://www.eionet.europa.eu/gemet/concept/8922"}],"keywordsPlace":[{"value":"Morecambe Bay","uri":"http://sws.geonames.org/2642213"},{"value":"Essex","uri":"http://sws.geonames.org/2649889"}],"keywordsProject":[{"value":"BESS"},{"value":"CBESS"}],"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":"The location of the sample sites was determined by randomly allocated quadrats. Twenty-two 1 x 1 m quadrats were randomly allocated to each mudflat and saltmarsh site using R (R Development Core Team, 2014) to specify four different spatial scales (A = 1 quadrat only, B = 3 quadrats at 1 m to 10 m apart, C = 6 quadrats at 10 m to 100 m apart, D = 12 quadrats at 100 m to 1000 m or site maximum). These quadrats are common to all CBESS quadrat data. NDVI measurements were obtained before any destructive harvesting of the quadrats. \n\nAn OceanOptics USB2000 spectrometer with a 1.5 m fibre optic was used in all measurements. OOIBase32 Version 2.0.1.3 was used to log data on a laptop. Reflectance measurements were taken at 1.5 m above the ground surface. At each quadrat: 1) the integration time of the spectrometer was adjusted such that the peak of the white reference spectra was approx 75% of the spectrometers maximum level; 2) for short integration times (<100 ms) spectral averaging was used to reduce measurement noise; 3) a dark measurement was recorded; 4) a white reference measurement was recorded; and 5) the reflectance measurement was made. A note is made of the number of the OOBase files associated with the quadrat number and percentage cloud and water cover of the quadrat and any other relevant information are taken. NDVI is calculated in Matlab.","metadataDate":"2026-06-29T16:36:20","notGEMINI":false,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/data/75b1f669-66b3-472b-9d31-eda908826e17","name":"Download the data","description":"Download a copy of these data","function":"download","type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/sd/75b1f669-66b3-472b-9d31-eda908826e17.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"pointsOfContact":[{"honorificPrefix":"Dr","familyName":"Hill","givenName":"Tim","organisationName":"University of Exeter","organisationIdentifier":"https://ror.org/03yghzc09","role":"pointOfContact","email":"t.c.hill@exeter.ac.uk","address":{"deliveryPoint":"Amory Building, Rennes Drive","city":"Exeter","administrativeArea":" ","postalCode":"EX4 4RJ","country":"UK"},"fullName":"Hill, T.","pointOfContact":"University of Exeter"}],"publicationDate":"2015-12-31T00:00:00.000Z","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":"413dc2b2-f38b-4f8a-a198-f78b07534fb8"}],"resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/75b1f669-66b3-472b-9d31-eda908826e17"},{"code":"10.5285/75b1f669-66b3-472b-9d31-eda908826e17","codeSpace":"doi"}],"resourceMaintenance":[{"frequencyOfUpdate":"notPlanned","note":"Dataset is complete"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"honorificPrefix":"Dr","familyName":"Hill","givenName":"Tim","organisationName":"University of Exeter","organisationIdentifier":"https://ror.org/03yghzc09","role":"pointOfContact","email":"t.c.hill@exeter.ac.uk","address":{"deliveryPoint":"Amory Building, Rennes Drive","city":"Exeter","administrativeArea":" ","postalCode":"EX4 4RJ","country":"UK"},"fullName":"Hill, T.","pointOfContact":"University of Exeter"},{"familyName":"Hill","givenName":"T.C.","organisationName":"University of Exeter","organisationIdentifier":"https://ror.org/03yghzc09","role":"author","email":"t.c.hill@exeter.ac.uk","fullName":"Hill, T.C."},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"custodian","email":"info@eidc.ac.uk"},{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"},{"organisationName":"University of Exeter","organisationIdentifier":"https://ror.org/03yghzc09","role":"rightsHolder"}],"rightsHolders":[{"organisationName":"University of Exeter","organisationIdentifier":"https://ror.org/03yghzc09","role":"rightsHolder"}],"spatialReferenceSystems":[{"code":"http://www.opengis.net/def/crs/EPSG/0/27700","title":"OSGB 1936 / British National Grid"}],"spatialRepresentationTypes":["textTable"],"temporalExtents":[{"begin":"2013-01-01","end":"2013-08-31"}],"title":"Coastal Biodiversity and Ecosystem Service Sustainability (CBESS) Normalised Difference Vegetation Index (NDVI) in saltmarsh and mudflat habitats","topicCategories":[{"value":"oceans","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/oceans"}],"type":"dataset","uri":"https://catalogue.ceh.ac.uk/id/75b1f669-66b3-472b-9d31-eda908826e17","useConstraints":[{"value":"© University of Exeter","code":"copyright"},{"value":"This resource is made available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"}]}
