Despite being the most abundant beaked whale in the Arctic and subarctic, information on the behavior of northern bottlenose whales (\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>Hyperoodon ampullatus<\/jats:italic>\n                    <\/jats:styled-content>\n                    ) is limited. This study used records from 13 satellite tags deployed off Jan Mayen in June\u2013July 2014\u20132016 to provide an extensive description of the dive behavior of\n                    <jats:italic>Hyperoodon<\/jats:italic>\n                    for the Nordic Seas. A total of 8372 dives, collected over 224\u2009days (or 5376\u2009h), were analyzed. The whales performed extreme dives of up to 2288\u2009m deep and 98\u2009min long\u2014deeper and longer than previously reported for behavior in presumed undisturbed contexts. Individuals spent on average 18% of the time at depths shallower than 40\u2009m, and 22%, 47%, and 12% in epi\u2010, meso\u2010, and bathypelagic dives, respectively. Epipelagic dives averaged 123\u2009m (s.d.: 46\u2009m) in depth and 11\u2009min (5\u2009min) in duration. Mesopelagic dives averaged 441\u2009m (217\u2009m) and 24\u2009min (11\u2009min) and were performed at a mean rate of 1.46\u2009h\n                    <jats:sup>\u22121<\/jats:sup>\n                    . Bathypelagic dives averaged 1487\u2009m (366\u2009m) and 55\u2009min (13\u2009min) and were performed at a mean rate of 0.23\u2009h\n                    <jats:sup>\u22121<\/jats:sup>\n                    . The distribution of dive depths was less bimodal than typically reported for other beaked whales, and all dive profiles contained periods of continuous, consecutive deep dives. Benthic diving occurred at meso\u2010 and especially bathypelagic depths and was individual specific, varying from 8% to 51% of the animal's bathypelagic dives. Overall, our findings demonstrate that northern bottlenose whales have extraordinary capabilities to dive, and presumably feed, throughout the water column including at the sea floor. High rates of deep dives highlight the importance of the Iceland and Norwegian Seas to this population of deep\u2010sea predators.\n                  <\/jats:p>","DOI":"10.1002\/ece3.71862","type":"journal-article","created":{"date-parts":[[2025,7,30]],"date-time":"2025-07-30T23:23:44Z","timestamp":1753917824000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Long\u2010Term Depth Records of Satellite\u2010Tagged Northern Bottlenose Whales Reveal Extraordinary Dive Capabilities"],"prefix":"10.1002","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-6816-9237","authenticated-orcid":false,"given":"Barbara K.","family":"Neubarth","sequence":"first","affiliation":[{"name":"Faculty of Life and Environmental Sciences, School of Engineering and Natural Sciences University of Iceland  Reykjav\u00edk Iceland"},{"name":"Coastal and Marine Management University Centre of the Westfjords  \u00cdsafj\u00f6r\u00f0ur Iceland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick J.
