Moving 6-year analysis of Water body chlorophyll-a in the NorthEast Atlantic for each season:\n - winter: January-March,\n - spring: April-June,\n - summer: July-September,\n - autumn: October-December. \nEvery year of the time dimension corresponds to the 6-year centred average of each season. 6-year periods span from 1971/1976 until 2016/2021. Observation data span from 1971 to 2021. \nHigh-frequency observation trails were filtered to a 3h temporal resolution. \nDepth levels (International Oceanographic Data Exchange (IODE) standard depths): [0.0, 5.0, 10.0, 20.0, 30.0, 40.0, 50.0, 75.0, 100.0, 125.0, 150.0, 200.0, 250.0, 300.0]. \nData sources: observational data from SeaDataNet/EMODNet Chemistry Data Network. \nDescrption of DIVAnd analysis: the computation was done with DIVAnd (Data-Interpolating Variational Analysis in n dimensions), version 2.7.4, using GEBCO 30 sec topography for the spatial connectivity of water masses. The horizontal resolution of the produced DIVAnd maps is 0.1 degrees. Horizontal correlation length varies from 200km in open sea regions to 50km at the coast. Vertical correlation length is defined as twice the vertical resolution. 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: a vertically-filtered profile of the seasonal data mean value (including all years) is substracted from the data. \nDetrending of data: no, advection constraint applied: no. \nUnits: mg/m3.\n\ncdm_data_type = Grid\nVARIABLES (all of which use the dimensions [time][latitude][longitude]):\nWater_body_chlorophyll_a_deepest (Deepest values of Water body chlorophyll-a, mg/m3)\n /erddap/metadata/fgdc/xml/V2023_chemistry_6f52_04de_e8a0_fgdc.xml /erddap/metadata/iso19115/xml/V2023_chemistry_6f52_04de_e8a0_iso19115.xml /erddap/info/V2023_chemistry_6f52_04de_e8a0/index.htmlTable http://opendap.oceanbrowser.net/thredds/dodsC/data/emodnet-projects/v2023/By_sea_regions/Northeast_Atlantic_Ocean/Water_body_chlorophyll-a.4Danl.nc.html (external link) https://erddap.emodnet.eu/erddap/rss/V2023_chemistry_6f52_04de_e8a0.rss /erddap/subscriptions/add.html?datasetID=V2023_chemistry_6f52_04de_e8a0&showErrors=false&email= IFREMER, SISMER, Scientific Information Systems for the SEA V2023_chemistry_6f52_04de_e8a0

Seasonal climatology of Water body chlorophyll-a for Loire river for the period 1971-2021 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 2021. \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 2.7.4, 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): 14000 (winter), 52000 (spring), 42000 (summer), 125000 (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.
