37271 Kogia sima click characteristics Document Published / External 30990 PSD- Cetacean Research Program (CRP) Publications Portfolio Project Completed 2018-04-18 The two species of the genus Kogia are widely distributed throughout the world's temperate and tropical oceans, but because they are small and highly cryptic, they are difficult to monitor. The acoustic signals of K. breviceps have been described previously, but the signals of K. sima have remained unknown. Here we present three recordings of K. sima, two from free‐ranging animals and one from a captive setting, representing both the Atlantic Ocean and Pacific Ocean. The acoustic signals of K. sima are very similar to the signals of K. breviceps and other species that have narrow‐band, high‐frequency (NBHF) clicks. Free‐ranging K. sima produce “usual” clicks that have mean peak and centroid frequencies of 127–129 kHz, mean −3 dB bandwidth of 10 kHz, mean −10 dB bandwidth of 16–17 kHz, and mean interclick interval of 110–164 ms. Although K. sima clicks cannot yet be distinguished from those of K. breviceps or other NBHF clicking species, our detailed description of this species' signals reveals the similarities between the two Kogia species, and thus allows for passive acoustic monitoring of the genus Kogia in regions where other NBHF species are not present. https://doi.org/10.1111/mms.12488 Theme Atlantic Theme Florida Theme Guam Theme Kogia sima Theme Pacific Theme The Bahamas Theme biosonar Theme click Theme dwarf sperm whale Theme echolocation Theme narrow-band high-frequency Pacific Islands Fisheries Science Center Honolulu HI USA Journal article Microsoft Word Planned Author 2017-03-14 Person Merkens, Karlina PB karlina.merkens@noaa.gov 1845 Wasp Blvd. Honolulu HI 96818 USA (808)725-5749 Data Steward 2017-03-14 Person Merkens, Karlina PB karlina.merkens@noaa.gov 1845 Wasp Blvd. Honolulu HI 96818 USA (808)725-5749 Distributor 2017-03-14 Organization Pacific Islands Fisheries Science Center PIFSC pifsc.info@noaa.gov https://ror.org/02apffz65 1845 Wasp Blvd. Honolulu HI 96818 USA 808-725-5360 https://www.pifsc.noaa.gov Pacific Island Fisheries Science Center homepage Online Resource 8:00 a.m. - 4:30 p.m. Metadata Contact 2017-03-14 Person Merkens, Karlina PB karlina.merkens@noaa.gov 1845 Wasp Blvd. Honolulu HI 96818 USA (808)725-5749 Point of Contact 2017-03-14 Person Merkens, Karlina PB karlina.merkens@noaa.gov 1845 Wasp Blvd. Honolulu HI 96818 USA (808)725-5749 144 145 13.5 13 -77.5 -77 26.1 25.5 Range 2002 2016 Unclassified Requester will be asked to submit a request by email to Erin Oleson (erin.oleson@noaa.gov) or Karlina Merkens (karlina.merkens@noaa.gov) Requester will be asked to submit a request by email to Erin Oleson (erin.oleson@noaa.gov) or Karlina Merkens (karlina.merkens@noaa.gov) Requester will be asked to submit a request by email to Erin Oleson (erin.oleson@noaa.gov) or Karlina Merkens (karlina.merkens@noaa.gov) Requester will be asked to submit a request by email to Erin Oleson (erin.oleson@noaa.gov) or Karlina Merkens (karlina.merkens@noaa.gov) none none https://onlinelibrary.wiley.com/doi/abs/10.1111/mms.12488 gov.noaa.nmfs.inport:37271 Karlina Merkens 2017-03-14T17:38:49 SysAdmin InPortAdmin 2025-12-03T01:00:28 2019-07-17 Pacific Islands Fisheries Science Center PIFSC 1845 Wasp Blvd. Honolulu HI 96818 USA 808-725-5300 https://www.pifsc.noaa.gov 8:00 a.m. - 4:30 p.m. 1001 Public No 2019-07-17 1 Year 2020-07-17
