Capture locations were transcribed from North American (“Yankee”) pelagic whale vessel log books dating from 1761 to 1920 and plotted onto nautical charts in a Mercator projection by a cartographer. Each point plotted on the charts represents the location of a whaling ship on a day when one or more whales were taken and is symbolized by month of the year using a combination of color and open and closed circles.\nTownsend and his cartographer plotted vessel locations as accurately as possible according to log book records.  When plotting locations on an earlier sperm whale chart published in 1931 the cartographer spaced points where locations were very dense, \"extending areas slightly\" for a number of whaling grounds. However, for charts in preparation at this time, Townsend states that \"this difficulty is avoided by omitting some of the data, rather than extend the ground beyond actual whaling limits.\" We assumed that this statement refers to the 1935 charts but there is still some question as to whether the cartographer did in fact space locations and thus expand whaling grounds.\n","intellectualrights":"This work is licensed under a  Creative Commons Attribution (CC-BY) 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":"Gillian","surname":"Woolmer","organization":"WCS Canada","position":"Primary contact","email":"gwoolmer@wcs.org","url":"http://www.wcscanada.org","organization_oceanexpert_id":null,"type_display":"Creator"},{"role":null,"type":"contact","givenname":"Gillian","surname":"Woolmer","organization":"WCS Canada","position":"Primary contact","email":"gwoolmer@wcs.org","url":"http://www.wcscanada.org","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":"Gillian","surname":"Woolmer","organization":"WCS Canada","position":"Primary contact","email":"gwoolmer@wcs.org","url":"http://www.wcscanada.org","organization_oceanexpert_id":null,"type_display":"Owner"},{"role":"owner","type":"personnel","givenname":"Gillian","surname":"Woolmer","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":"whales","thesaurus":"N/A"},{"keyword":"charts","thesaurus":"N/A"},{"keyword":"sperm whale","thesaurus":"N/A"},{"keyword":"humpback whale","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":2611,"records":8365737},{"year":2025,"downloads":6831,"records":85273519},{"year":2024,"downloads":4860,"records":110640621},{"year":2023,"downloads":4176,"records":84520777},{"year":2022,"downloads":36851,"records":60535195},{"year":2021,"downloads":3699,"records":67028952},{"year":2020,"downloads":1388,"records":22562416},{"year":2019,"downloads":426,"records":3174320},{"year":2018,"downloads":10,"records":10122}],"tags":null,"disable_extensions":null}]}
