Data were collected during 3 major field experiments between 1981 and 1985, divided into two periods: First International BIOMASS Experiment (FIBEX) in 1980-1981, and the Second International BIOMASS Experiment (SIBEX) in 1983-1985.\nIn total 34 cruises were carried out (El-Sayed, online resource), of which  21 cruises were gathered in this data set. This data set provides sea-bird observation collected in the cruises.\n\nReference\nFor full citation information, see [Cross Reference].\n</p>\n        ","intellectualrights":"This work is licensed under a  Creative Commons Attribution Non Commercial (CC-BY-NC) 4.0 License","feed":{"id":"18954703-9b9d-4584-b46d-87846532c5ee","url":"https://ipt.env.duke.edu/rss.do","website":"https://ipt.env.duke.edu","active":true},"institutes":[{"name":"Duke University","oceanexpert_id":19393,"oceanexpert_parent_id":null}],"contacts":[{"role":null,"type":"creator","givenname":"Helen","surname":"Campbell","organization":"Helen Campbell","position":"Primary contact","email":"unknown@dummy.com","url":null,"organization_oceanexpert_id":null,"type_display":"Creator"},{"role":null,"type":"contact","givenname":"Helen","surname":"Campbell","organization":"Helen Campbell","position":"Primary contact","email":"unknown@dummy.com","url":null,"organization_oceanexpert_id":null,"type_display":"Contact"},{"role":null,"type":"metadataProvider","givenname":null,"surname":"OBIS-SEAMAP","organization":"Marine Geospatial Ecology Lab, Duke University","position":null,"email":"seamap-contact@duke.edu","url":"https://seamap.env.duke.edu","organization_oceanexpert_id":19393,"type_display":"Metadata Provider"},{"role":"distributor","type":"associatedParty","givenname":null,"surname":"OBIS-SEAMAP","organization":"Marine Geospatial Ecology Lab, Duke University","position":null,"email":"seamap-contact@duke.edu","url":"https://seamap.env.duke.edu","organization_oceanexpert_id":19393,"type_display":"Distributor"},{"role":"owner","type":"associatedParty","givenname":"Helen","surname":"Campbell","organization":"Helen Campbell","position":"Primary contact","email":"unknown@dummy.com","url":null,"organization_oceanexpert_id":null,"type_display":"Owner"},{"role":"owner","type":"personnel","givenname":"Helen","surname":"Campbell","organization":null,"position":null,"email":null,"url":null,"organization_oceanexpert_id":null,"type_display":"Owner"}],"nodes":[{"id":"573654c1-4ce7-4ea2-b2f1-e4d42f8f9c31","name":"OBIS-SEAMAP"}],"keywords":[{"keyword":"Occurrence","thesaurus":"GBIF Dataset Type Vocabulary: http://rs.gbif.org/vocabulary/gbif/dataset_type.xml"},{"keyword":"Observation","thesaurus":"GBIF Dataset Subtype Vocabulary: http://rs.gbif.org/vocabulary/gbif/dataset_subtype.xml"},{"keyword":"Marine Biology","thesaurus":"N/A"},{"keyword":"Visual sighting","thesaurus":"N/A"},{"keyword":"Vessels","thesaurus":"N/A"},{"keyword":"Sightings","thesaurus":"N/A"},{"keyword":"Sea-bird","thesaurus":"N/A"},{"keyword":"Sea bird","thesaurus":"N/A"},{"keyword":"Bird","thesaurus":"N/A"},{"keyword":"seabirds","thesaurus":"N/A"},{"keyword":"marine birds","thesaurus":"N/A"},{"keyword":"Biological Investigations of Marine Antarctic Systems and Stocks","thesaurus":"N/A"},{"keyword":"BIOMASS","thesaurus":"N/A"},{"keyword":"Krill","thesaurus":"N/A"},{"keyword":"Ship survey","thesaurus":"N/A"},{"keyword":"at-sea distributions","thesaurus":"N/A"},{"keyword":"Occurrence","thesaurus":"GBIF Dataset Type Vocabulary: http://rs.gbif.org/vocabulary/gbif/dataset_type_2015-07-10.xml"}],"downloads":[{"year":2026,"downloads":616,"records":2773162},{"year":2025,"downloads":3156,"records":38018150},{"year":2024,"downloads":3857,"records":52857285},{"year":2023,"downloads":3115,"records":40617340},{"year":2022,"downloads":6679,"records":29125591},{"year":2021,"downloads":2607,"records":32161487},{"year":2020,"downloads":861,"records":10833643},{"year":2019,"downloads":135,"records":1018278},{"year":2018,"downloads":1,"records":389}],"tags":null,"disable_extensions":null}]}
