The trawls were conducted in a vertical direction at a speed of 1 m/s, stratified between the depth levels of 0-20 m, 20-60 m, and 60-150 m, resulting in a total of 99 zooplankton harvests.","EngDescr":"\tThe samples were preserved in borax-buffered 5% formalin (pH 8.5 - 9). The biovolume of the samples was calculated using the displaced volume method, with the largest organisms (&gt;1cm) removed beforehand. The biomass of zooplankton was measured in m1/m3. The zooplankton were identified and counted using stereomicroscopes in counting chambers (with grid of 50 squares with about 1 cm on a side).\n\nThe spatial and temporal variability of zooplankton during sardine spawning (May) in an area off Porto - Figueira da Foz was analysed. The distribution of zooplankton in the water column indicated a day-night rhythm of vertical migration, since the biomass between 20 and 60 meters depth was significantly higher during the night that during the day. From the application of principal component analysis to the more frequent taxa the following spatio-temporal patterns were obtained: a) A community with neritic characteristics was identified in position to a community with oceanic characteristics. This aspect of spatial variability weighted highly in the total variability of the samples. b) Vertical stratification by taxonomic groups and the influence of hidrodinâmica processes (daily advection) on zooplanktonic communities. c) Changes with time in the distribution of some species seem to have been determined by saline fronts.","OrigAbstract":null,"OrigDescr":null,"Comments":null,"ReleaseDate":"Dec  6 2022 12:00AM","ReleaseDate0":"2022-12-06","OrigDescrLang":null,"EmbargoDate":null,"OrigDescrLangNL":null,"OrigLangCode":null,"OrigLangCodeExtended":null,"OrigLangID":null,"DescrCompFlag":null,"DescrTransFlag":null,"Citation":null,"AccessConstraints":null,"UDate":"2026-01-26","CDate":"2022-10-17","CurrencyDate":null,"RevisionDate":null,"DateLastModified":{"date":"2026-05-14 01:44:00.153333","timezone_type":1,"timezone":"+02:00"},"CheckedFlag":0,"PublicFlag":1,"VlizCoreFlag":1,"MarineFlag":1,"FreshFlag":0,"BrackishFlag":0,"TerrestrialFlag":0,"StatusID":1,"DasType":"Data","DasTypeID":1,"DasOrigin":"Research: field survey","Progress":"Completed","AccessConstraint":"Attribution-NonCommercial (CC BY-NC)","AccConstrEN":"Attribution-NonCommercial (CC BY-NC)","AccConstrDisplay":"<a rel=\"license\" href=\"https://creativecommons.org/licenses/by-nc/4.0/\" target=\"_blank\"><img alt=\"Creative Commons License\" style=\"border:0px;height:15px;width:80px;vertical-align:middle;\" src=\"https://www.marinespecies.org/aphia/images/cc/by-nc.png\" /></a> This dataset is licensed under a <a rel=\"license\" href=\"https://creativecommons.org/licenses/by-nc/4.0/\" target=\"_blank\">Creative Commons Attribution-NonCommercial 4.0 International License</a>.","License":"https://creativecommons.org/licenses/by-nc/4.0","AccConstrDescription":"This license lets others remix, tweak, and build upon your work non-commercially, and although their new works must also acknowledge you and be non-commercial, they don’t have to license their derivative works on the same terms","Lineage":"Prior to publication data undergo quality control checked which are described in https://github.com/EMODnet/EMODnetBiocheck?tab=readme-ov-file#understanding-the-output","AccConID":24,"GBIF_UUID":"bdbe7271-1d2d-4229-bfde-d451a97686ed"},"dois":null,"spcols":[{"SpColID":619,"SpName":"available through EurOBIS"},{"SpColID":552,"SpName":"EMODNET"}],"keywords":[{"ThesaurusTerm":"Bio-geographical regions","ThesTypID":7,"ThesType":"INSPIRE themes","Code":"br","Description":"Areas of relatively homogeneous ecological conditions with common characteristics.","OrigThesTerm":"Bio-geographical regions","DutchTerm":"Biogeografische gebieden","URI":"https://inspire.ec.europa.eu/theme/br","DasKeywordDescr":null},{"ThesaurusTerm":"Biota","ThesTypID":16,"ThesType":"INSPIRE Topics","Code":"biota","Description":"Flora and/or fauna in natural environment.","OrigThesTerm":"Biota","DutchTerm":"Biota","URI":"https://inspire.ec.europa.eu/metadata-codelist/TopicCategory/biota","DasKeywordDescr":null},{"ThesaurusTerm":"Environment","ThesTypID":16,"ThesType":"INSPIRE Topics","Code":"environment","Description":"Environmental resources, protection and conservation.","OrigThesTerm":"Environment","DutchTerm":"Milieu","URI":"https://inspire.ec.europa.eu/metadata-codelist/TopicCategory/environment","DasKeywordDescr":null},{"ThesaurusTerm":"EurOBIS calculated BBOX","ThesTypID":35,"ThesType":"Geoterms no link Marine Regions","Code":null,"Description":null,"OrigThesTerm":"EurOBIS calculated BBOX","DutchTerm":null,"URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Geoscientific Information","ThesTypID":16,"ThesType":"INSPIRE Topics","Code":"geoscientificInformation","Description":"Information pertaining to earth sciences.","OrigThesTerm":"Geoscientific Information","DutchTerm":"Geowetenschappelijke informatie","URI":"https://inspire.ec.europa.eu/metadata-codelist/TopicCategory/geoscientificInformation","DasKeywordDescr":null},{"ThesaurusTerm":"Habitats and biotopes","ThesTypID":7,"ThesType":"INSPIRE themes","Code":"hb","Description":"Geographical areas characterised by specific ecological conditions, processes, structure, and (life support) functions that physically support the organisms that live there.
