In 2002 and 2004, the surveys were a continuation of those done in 1999 and 2000, taking advantage of the survey platform as it ran transects through SEBS. In 2008 and 2010, the cetacean survey was included as part of the Bering Sea Integrated Ecosystem Research Program, a NPRB funded project to test and improve our understanding of effects of climate change and management actions on the Bering Sea ecosystem. \r\n\r\nMethods in all years were the same with three observers rotating through two 25x (Big Eye) binocular positions and one recorder on the flying bridge. Survey effort was conducted along the pollock survey transect lines, weather permitting. Additional effort was conducted while in transit to and from pollock survey waypoints. Transect survey effort was 3,761 km in 2002, 1,692 km in 2004 (observers were present for only half of the survey), 3,255 km in 2008 and 1,681 km in 2010. \r\n\r\nThe following cetacean species were recorded: fin whale (<i>Balaenoptera physalus</i>), sei whale (<i>Balaenoptera borealis</i>), minke whale (<i>Balaenoptera acutorostrata</i>), humpback whale (<i>Megaptera novaeangliae</i>), gray whale (<i>Eschrichtius robustus</i>), sperm whale (<i>Physeter macrocephalus</i>), Baird’s beaked whale (<i>Berardius bairdii</i>), Stejneger’s beaked whale (<i>Mesoplodon stejnegeri</i>), killer whale (<i>Orcinus orca</i>), Pacific white-sided dolphin (<i>Lagenorhynchus obliquidens</i>), Dall’s porpoise (<i>Phocoenoides dalli</i>), and harbor porpoise (<i>Phocoena phocoena</i>). Pinniped species were also recorded to include the Steller sea lion (<i>Eumetopias jubatus</i>) and the northern fur seal (<i>Callorhinus ursinus</i>), as well as the sea otter (<i>Enhydra lutris</i>). \r\n\r\nFin whales were the most common large whale, and Dall's porpoises were the most common small cetacean. Distribution, abundance estimates and population trends for fin, humpback, and minke whales, and Dall’s and harbor porpoise are currently being analyzed.","OrigAbstract":null,"OrigDescr":null,"Comments":null,"ReleaseDate":null,"ReleaseDate0":null,"OrigDescrLang":null,"EmbargoDate":null,"OrigDescrLangNL":null,"OrigLangCode":null,"OrigLangCodeExtended":null,"OrigLangID":null,"DescrCompFlag":0,"DescrTransFlag":0,"Citation":null,"AccessConstraints":null,"UDate":"2013-04-25","CDate":"2012-11-29","CurrencyDate":null,"RevisionDate":null,"DateLastModified":{"date":"2026-05-30 01:37:59.451226","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":null,"AccConID":24},"dois":null,"spcols":null,"keywords":[{"ThesaurusTerm":"IN, Bering Sea","ThesTypID":34,"ThesType":"ASFA Geoterms","Code":null,"Description":null,"OrigThesTerm":"IN, Bering Sea","DutchTerm":null,"URI":null,"DasKeywordDescr":null}],"parents":null,"children":null,"othrel":null,"othrelrev":[{"DasID":1865,"Acronym":"OBIS-SEAMAP","StandardTitle":"Spatial Ecological Analysis of Megavertebrate Populations","Relation":"Published dataset","RelationY":"Published in","RelID":13,"doi":null,"vlizDoi":null}],"ownerships":[{"OrderNr":1,"Surname":null,"Firstname":null,"Initials":null,"PerPublicFlag":null,"AdrID":null,"Email":null,"InsPublicFlag":1,"Acronym":null,"OrigNameLangCode":null,"OrigNameLangID":null,"FullOrigName":null,"InsOwnerCNT":2,"PersID":null,"InsID":1120,"FullInstitute":"National Oceanic and Atmospheric Administration;
