Mesozooplankton was sampled using a vertical Juday plankton net with a 0.1 m² mouth opening and a mesh size of 150 μm. Vertical hauls were carried out from 2 m above the seabed or from the lower boundary of the oxic layer to the surface at designated sampling horizons. The wire length required to reach the target depth was determined by accounting for both the wire angle and its deployed length. Samples were preserved in a 4% formaldehyde solution buffered to pH 8.0–8.2 with disodium tetraborate (borax, Na₂B₄O₇·10H₂O), prepared by mixing one part of 40% formaldehyde with nine parts water/sample, and stored in plastic containers. Before laboratory analysis, samples were concentrated to a volume of 100–150 cm³ and divided into sub-samples. Quantitative analyses (abundance and biomass based on species-specific individual weights) and taxonomic identification were performed using a Bogorov counting chamber under a stereoscopic zoom microscope. At least 100 individuals of each of the three dominant species were counted in every sub-sample. According to Alexandrov et al. (2014), this counting procedure provides an abundance estimate with a precision of approximately 20% for the three dominant groups. Species were identified following the taxonomic keys of Mordukhay-Boltovskoy (1968, 1969, 1972).\n        \n        \n        ","language":"eng","citation":{"text":"Ukrainian Scientific Centre of Ecology of the Sea (UkrSCES): National Monitoring Studies 2009, (Mesozooplankton) https://doi.org/10.15468/jwznst accessed via GBIF.org on 2026-10-21.","citationProvidedBySource":true},"contactsCitation":[],"lockedForAutoUpdate":false,"createdBy":"b9a1023a-e508-4168-a837-fa0781820a8b","modifiedBy":"crawler.gbif.org","created":"2026-08-10T11:27:53.699+00:00","modified":"2026-08-10T12:53:10.275+00:00","contacts":[{"key":7103443,"type":"ORIGINATOR","primary":true,"userId":[],"firstName":"Mykhailo","lastName":"NABOKIN","position":[],"email":[],"phone":[],"homepage":[],"organization":"Ukrainian Scientific Centre of Ecology of the Sea (UkrSCES)","address":[],"createdBy":"crawler.gbif.org","modifiedBy":"crawler.gbif.org","created":"2026-08-10T12:53:10.256+00:00","modified":"2026-08-10T12:53:10.256+00:00"},{"key":7103444,"type":"USER","primary":false,"userId":[],"firstName":"Oleksandr","lastName":"Neprokin","position":[],"email":["o.neprokin@gmail.com"],"phone":[],"homepage":[],"organization":"Ukrainian Scientific Centre of Ecology of the Sea (UkrSCES)","address":[],"createdBy":"crawler.gbif.org","modifiedBy":"crawler.gbif.org","created":"2026-08-10T12:53:10.257+00:00","modified":"2026-08-10T12:53:10.257+00:00"},{"key":7103445,"type":"ADMINISTRATIVE_POINT_OF_CONTACT","primary":true,"userId":[],"firstName":"Olena","lastName":"Miasnikova","position":[],"email":[],"phone":[],"homepage":[],"organization":"Ukrainian Scientific Centre of Ecology of the Sea (UkrSCES)","address":[],"createdBy":"crawler.gbif.org","modifiedBy":"crawler.gbif.org","created":"2026-08-10T12:53:10.259+00:00","modified":"2026-08-10T12:53:10.259+00:00"}],"endpoints":[{"key":1312399,"type":"DWC_ARCHIVE","url":"http://gp.sea.gov.ua:8082/ipt/archive.do?r=ukrmon_2009","createdBy":"b9a1023a-e508-4168-a837-fa0781820a8b","modifiedBy":"b9a1023a-e508-4168-a837-fa0781820a8b","created":"2026-08-10T12:52:09.404+00:00","modified":"2026-08-10T12:52:09.404+00:00","machineTags":[]},{"key":1312398,"type":"EML","url":"http://gp.sea.gov.ua:8082/ipt/eml.do?r=ukrmon_2009","createdBy":"b9a1023a-e508-4168-a837-fa0781820a8b","modifiedBy":"b9a1023a-e508-4168-a837-fa0781820a8b","created":"2026-08-10T12:52:09.327+00:00","modified":"2026-08-10T12:52:09.327+00:00","machineTags":[]}],"machineTags":[{"key":33267279,"namespace":"crawler.gbif.org","name":"crawl_attempt","value":"9","createdBy":"crawler.gbif.org","created":"2026-10-19T01:04:32.227+00:00"}],"tags":[],"identifiers":[{"key":471941,"type":"UUID","identifier":"f76eabca-24b3-47f7-bdc0-1c6b82046dbc","createdBy":"crawler.gbif.org","created":"2026-08-10T12:53:10.260+00:00","primary":false},{"key":471930,"type":"URL","identifier":"http://gp.sea.gov.ua:8082/ipt/resource?r=ukrmon_2009","createdBy":"crawler.gbif.org","created":"2026-08-10T11:28:54.617+00:00","primary":false}],"comments":[],"bibliographicCitations":[],"curatorialUnits":[],"taxonomicCoverages":[],"geographicCoverages":[{"description":"North-western part of the Black Sea","boundingBox":{"minLatitude":46.012,"maxLatitude":46.755,"minLongitude":30.081,"maxLongitude":32.168,"globalCoverage":false}}],"temporalCoverages":[{"@type":"range","start":"2009-01-15T00:00:00.000+00:00","end":"2009-11-18T00:00:00.000+00:00"}],"keywordCollections":[{"thesaurus":"GBIF Dataset Type Vocabulary: http://rs.gbif.org/vocabulary/gbif/dataset_type_2015-07-10.xml","keywords":["Sampling event"]}],"project":{"title":"National Monitoring Studies 2008","contacts":[{"type":"ADMINISTRATIVE_POINT_OF_CONTACT","primary":false,"userId":[],"firstName":"Oleksandr","lastName":"Leposhkin","position":[],"email":[],"phone":[],"homepage":[],"address":[]}],"awards":[],"relatedProjects":[]},"samplingDescription":{"methodSteps":[]},"countryCoverage":[],"collections":[],"dataDescriptions":[],"dataLanguage":"eng","pubDate":"2026-08-10T00:00:00.000+00:00","maintenanceUpdateFrequency":"AS_NEEDED","maintenanceDescription":"","license":"http://creativecommons.org/publicdomain/zero/1.0/legalcode","dwca":{"coreType":"http://rs.tdwg.org/dwc/terms/Event","extensions":["http://rs.tdwg.org/dwc/terms/Occurrence","http://rs.iobis.org/obis/terms/ExtendedMeasurementOrFact"],"modified":"2026-08-10T12:53:10.205+00:00"},"approximateCounts":{"occurrenceCount":220}}
