Ocean - Loire River - DIVAnd 4D seasonal analysis of Water body dissolved inorganic nitrogen 1971/2024 v2025. Seasonal climatology of Water body dissolved inorganic nitrogen for Loire river for the period 1971-2024 and for the following seasons:\n - winter: January-March,\n - spring: April-June,\n - summer: July-September,\n - autumn: October-December. \nObservation data span from 1971 to 2024. \nDepth levels (m): [0.0, 2.0, 4.0, 6.0, 8.0, 10.0, 15.0, 20.0, 25.0, 30.0, 35.0, 40.0, 45.0, 50.0, 60.0, 70.0, 80.0, 90.0, 100.0, 110.0, 120.0, 130.0]. \nData sources: observational data from SeaDataNet/EMODNet Chemistry Data Network. \nDescription of DIVAnd analysis: the computation was done with DIVAnd (Data-Interpolating Variational Analysis in n dimensions), version 2.7.12, using GEBCO 15 sec topography for the spatial connectivity of water masses. The horizontal resolution of the produced DIVAnd maps is 0.01 degrees. Horizontal correlation length is defined seasonally (in meters): 72000 (winter), 43000 (spring), 215000 (summer), 150000 (autumn). Vertical correlation length was optimized and vertically filtered and a seasonally-averaged profile was used (DIVAnd.fitvertlen). Signal-to-noise ratio was fixed to 1 for vertical profiles and 0.1 for time series to account for the redundancy in the time series observations. A logarithmic transformation (DIVAnd.loglin) was applied to the data prior to the analysis. Background field: the vertically-filtered data mean profile is substracted from the data. Detrending of data: no, advection constraint applied: no. \nUnits: umol/l.</gco:CharacterString>\n      </gmd:abstract>\n      <gmd:credit gco:nilReason=\"missing\"/>\n      <gmd:pointOfContact>\n

Ocean - Loire River - DIVAnd 4D seasonal analysis of Water body dissolved inorganic nitrogen 1971/2024 v2025. Seasonal climatology of Water body dissolved inorganic nitrogen for Loire river for the period 1971-2024 and for the following seasons:\n - winter: January-March,\n - spring: April-June,\n - summer: July-September,\n - autumn: October-December. \nObservation data span from 1971 to 2024. \nDepth levels (m): [0.0, 2.0, 4.0, 6.0, 8.0, 10.0, 15.0, 20.0, 25.0, 30.0, 35.0, 40.0, 45.0, 50.0, 60.0, 70.0, 80.0, 90.0, 100.0, 110.0, 120.0, 130.0]. \nData sources: observational data from SeaDataNet/EMODNet Chemistry Data Network. \nDescription of DIVAnd analysis: the computation was done with DIVAnd (Data-Interpolating Variational Analysis in n dimensions), version 2.7.12, using GEBCO 15 sec topography for the spatial connectivity of water masses. The horizontal resolution of the produced DIVAnd maps is 0.01 degrees. Horizontal correlation length is defined seasonally (in meters): 72000 (winter), 43000 (spring), 215000 (summer), 150000 (autumn). Vertical correlation length was optimized and vertically filtered and a seasonally-averaged profile was used (DIVAnd.fitvertlen). Signal-to-noise ratio was fixed to 1 for vertical profiles and 0.1 for time series to account for the redundancy in the time series observations. A logarithmic transformation (DIVAnd.loglin) was applied to the data prior to the analysis. Background field: the vertically-filtered data mean profile is substracted from the data.

Signal-to-noise ratio was fixed to 1 for vertical profiles and 0.1 for time series to account for the redundancy in the time series observations. A logarithmic transformation (DIVAnd.loglin) was applied to the data prior to the analysis. Background field: the vertically-filtered data mean profile is substracted from the data. Detrending of data: no, advection constraint applied: no. \nUnits: umol/l.</gco:CharacterString>\n      </gmd:abstract>\n      <srv:serviceType>\n        <gco:LocalName>OPeNDAP</gco:LocalName>\n      </srv:serviceType>\n      <srv:extent>\n        <gmd:EX_Extent>\n          <gmd:geographicElement>\n            <gmd:EX_GeographicBoundingBox>\n              <gmd:extentTypeCode>\n                <gco:Boolean>1</gco:Boolean>\n              </gmd:extentTypeCode>\n              <gmd:westBoundLongitude>\n                <gco:Decimal>-4.01</gco:Decimal>\n              </gmd:westBoundLongitude>\n              <gmd:eastBoundLongitude>\n                <gco:Decimal>-1.0099316</gco:Decimal>\n              </gmd:eastBoundLongitude>\n              <gmd:southBoundLatitude>\n                <gco:Decimal>46.25</gco:Decimal>\n              </gmd:southBoundLatitude>\n              <gmd:northBoundLatitude>\n                <gco:Decimal>47.999706</gco:Decimal>\n              </gmd:northBoundLatitude>\n            </gmd:EX_GeographicBoundingBox>\n          </gmd:geographicElement>\n        </gmd:EX_Extent>\n      </srv:extent>\n      <srv:couplingType>\n        <srv:SV_CouplingType codeList=\"https://data.noaa.gov/ISO19139/resources/codeList.xml#SV_CouplingType\" codeListValue=\"tight\">tight</srv:SV_CouplingType>\n      </srv:couplingType>\n      <srv:containsOperations>\n        <srv:SV_OperationMetadata>\n          <srv:operationName>\n            <gco:CharacterString>OPeNDAPDatasetQueryAndAccess</gco:CharacterString>\n          </srv:operationName>\n          <srv:DCP gco:nilReason=\"unknown\"/>\n          <srv:connectPoint>\n            <gmd:CI_OnlineResource>\n              <gmd:linkage>\n                <gmd:URL>https://erddap.emodnet.eu/erddap/griddap/oceanbrowser_opendap_eafe_0ec3_bec0</gmd:URL>\n              </gmd:linkage>\n              <gmd:protocol>\n                <gco:CharacterString>OPeNDAP:OPeNDAP</gco:CharacterString>\n              </gmd:protocol>\n              <gmd:name>\n                <gco:CharacterString>OPeNDAP</gco:CharacterString>\n              </gmd:name>\n              <gmd:description>\n                <gco:CharacterString>An OPeNDAP service for gridded data.
