The pulsed call sequences were stereotyped patterns composed of three or more pulsed call elements and were collected from two dolphins, separated into adjacent pools, and allowed to swim freely. Eight hydrophones and an overhead camera were used to determine the positions and directions of the participants. The mean peak frequency and source levels were 8.4 \u00b1 4.4 (standard deviation)\u201318.7 \u00b1\u200912.7 kHz and 160.8 \u00b1 3.8 to 176.4 \u00b1 7.9 dB re 1 \u03bcPa (peak-to-peak), respectively, depending on the element types. The elements were omnidirectional, with mean directivity index of 0.9 \u00b1 3.4 dB. The dolphins produced sequences, regardless of their relative position and direction to the lattice, leading to the adjacent pool where the conspecific was housed. They increased the amplitude by 6.5 \u00b1 4.6 dB as the distance from the caller to an arbitrary point in the adjacent pool doubled. These results suggest that callers broadcast pulsed call sequences in a wide direction to reach dispersed conspecifics. However, they can adjust the acoustic active space by controlling the source levels.<\/jats:p>","DOI":"10.1121\/10.0022377","type":"journal-article","created":{"date-parts":[[2023,11,10]],"date-time":"2023-11-10T12:43:36Z","timestamp":1699620216000},"page":"2974-2987","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":3,"title":["Directional and amplitude characteristics of pulsed call sequences in captive free-swimming Pacific white-sided dolphins (<i>Lagenorhynchus obliquidens<\/i>)"],"prefix":"10.1121","volume":"154","author":[{"given":"Yuka","family":"Mishima","sequence":"first","affiliation":[{"name":"Department of Marine Resources and Energy, Tokyo University of Marine Science and Technology 1 , 4-5-7, Konan, Minato-ku, Tokyo, 108-8477, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ikuo","family":"Matsuo","sequence":"additional","affiliation":[{"name":"Department of Information Science, Tohoku Gakuin University 2 , 2-1-1 Tenjinzawa, Izumi-ku, Sendai, 981-3193, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuu","family":"Karasawa","sequence":"additional","affiliation":[{"name":"Izu Mito Sea Paradise 3 , 3-1, Nagahama, Uchiura, Numazu-shi, Shizuoka, 410-0295, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marina","family":"Ishii","sequence":"additional","affiliation":[{"name":"Graduate School of Marine Science and Technology, Tokyo University of Marine Science and Technology 4 , 4-5-7, Konan, Minato-ku, Tokyo, 108-8477, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tadamichi","family":"Morisaka","sequence":"additional","affiliation":[{"name":"Cetacean Research Center, Graduate School of Bioresources, Mie University 5 , 1577, Kurimamachiya-cho, Tsu-shi, Mie, 514-8507, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","published-online":{"date-parts":[[2023,11,10]]},"reference":[{"key":"2023111012431609700_c1","doi-asserted-by":"publisher","first-page":"146","DOI":"10.1242\/jeb.037655","article-title":"Scanning sonar of rolling porpoises during prey capture dives","volume":"213","year":"2010","journal-title":"J.
